A
6Ps Pain Pallor Pulselessness Paresthesia Paralysis Pressure
24
Q
Fractures: Casts application
A
Retention can be done through casting or traction
Give choices of color so the child can feel some sense of control
Explain procedure
When applying: provide distraction by talking about hobbies, pets…
The cast being applied reassures them its ok because they feel warmth from the application
Ensure proper padding of all boney prominences
Apply a stocking net before casting to protect the skin from any sharp edges after its dry
25
Fractures: Casts: Care management
Let the cast dry completely
Dry from the inside to out before putting any pressure on it
Use a fan or a cool air hair dryer may be helpful to get cast dry if it is very humid
Always use the palms of hands while its wet, using fingers leaves indentations which cause pressure points
26
Fractures: Cast at home care
Provide instructions on how to take care of cast. Keep the extremity elevated for the first 24hr to prevent swelling, observe for extremities for swelling and discoloration, checking for movement or sensation
Activity restriction, not allowing the child to put anything down the cast, it might get itchy and kids want to scratch it
Teach about crutch walking
27
Fractures: Cast: skin care
Teach hygiene because its important as well as how to pay special attention to skin care
Maintain child's skin integrity while they are in casts
28
Fractures: Cast: assessment
Unusual odor beneath the cast
Tingling, buring, numbness of toes or fingers
Drainage through cast to toes or fingers
Swelling or inability to move toes or fingers
Toes/fingers that are cold, blue, or white
Sudden unexplained fever
Pain that is not relieved by comfort measures
Unusual pain or nre pain that the child begins tp experience
Neurovascular assessment (CSM)
29
Fractures: Cast Care teaching
Petaling the edges of the cast (Especially when its a spica cast. Apply transparent dressing to edge of the cast and another one to childs perineum that acts as a continuous water proof bridge between the cast and the perineum in order to prevent leakage and allows for observation of the skin and area beneath the dressing)
Drying of the cast
Prevention of swelling (elevate, or if elbow: teach how to properly use a sling to provide support to the arm)
Protecting the cast from damage (cover before bathing or swimming)
When to call the dr
30
Spica cast
Used to immobilize the hip and thighs so that bones and tendons can heal properly
Starts at the chest and can either extend down one or both legs
Bar is a hip abductor to keep the legs in the proper position
Be sure not to use bar as a handle
Opening at the middle of the cast allows for elimination
Pose specific challenges like eating, feeding, positioning, bathing issues
Use disposable diapers
Potty trained children can use bedpan
Breastfeeding: use a football home
31
Traction for fracture
Pull or force that exerted on one part of the body
Balanced skeletal traction is applied to: Allow physiological stability, Align bone fragments, Enable closer evaluation of the injured site
Newer technology: orthopedic fixation devices that allow for mobility
32
Purpose of traction
```
Relieve fatigue in involved muscle
Position distal and proximal bone ends
Immobilize fracture site
Prevent deformity
Immobilize healing bone and prevent further injury
Reduce muscle spasms
```
33
Types of traction: Skeletal traction
Hardware is fixated to bone
34
Types of traction: Skin traction
Applying dressing to skin and traction is applied through dressing
35
Types of traction
```
Upper extremity
Lower extremity
Balance suspension
Gardner-Wells tong
Cervical (halo brace)
```
36
Types of traction: Lower extremity
```
Buck extension (Used for comfort measures for hip fractures)
Bryant traction (Developmental dysplasia of hip, when pelvic harness isnt working to keep the hips in place, used for 2-3 wks prior to surgery to loosen muscle around the hip joint)
Russell traction
```
37
Types of traction: Cervical
Used for about 6-8 wks before spinal instrumentation with scoliosis. Used for issues other than scoliosis
Corrects curvature greater than 80%, can be lessened to 50-60%
Continuous traditions
Children can ambulate despite having screws in their head
38
Traction care
Purpose: maintain bone alignment, prevent muscle spasms
Assessment of neurovascular status: don't have any coldness, cyanosis, pulselessness
Maintain correct balance between traction pull and counter-action force
Care for weights: NEVER adjust without orders
Skin inspection
Pin care
Developmental concerns
39
Immobilization affect on development: Toddlers
Need to explore and the ability to imitate behaviors in order to develop a sense of autonomy
Help this by giving them different items of different textures to explore and have them classify them
Anything to promote sense of exploration so that they can work to develop sense of autonomy
40
Immobilization affect on development: Preschoolers
Expression of initiative is evidenced by their need for vigorous physical activity. This is very hard for them to do when they are in traction. So whatever they can do with their unaffected extremities is good
41
Immobilization affect on development: School age
Sense of industry is influenced by physical achievement and competition. Maybe have competition with other children on their unit or with parents or board games. Or any game they can participate in that has simple rules
42
Immobilization affect on development: Adolescent
Rely on mobility to achieve independence, one of the steps in creating their identity. Give them as much independence as you can.
43
Pneumonic for traction care
```
T: Temp
R: Ropes hang freely on the traction
A: Alignment
C: Circulation (6Ps)
T: Type and location of fraction
I: Increase fluid intake so they don't get dehydrated or constipation
O: Overhead trapeze is there to help position them for comfort
N: No weights ever on the floor or bed
```
44
Compartment syndrom
```
Very serious!!!! Medical emergency!!!!!!
6Ps
Needs immediate intervention
Fasciotomy is performed when it occurs
Elevate extremity to the level of the heart
```
45
Developmental dysplasia of the Hip (DDH)
Refers to spectrum of disorders related to abnormal development of hip during fetal life, infancy, or childhood
Defined as condition where head of femur is improperly seated in the acetabulum of the pelvis
Girls are more commonly affected
Most are breech position
Strong family history
Cause is not completely known or understood
46
Developmental dysplasia of the Hip (DDH): Degrees: 1. Acetabular dysplasia (preluxation)
Mildest form
Delay in development of acetabulum defied by inadequate development of babies acetabulum.
Acetabulum is shallow and disk shaped rather than cup shape, osseous hypoplasia (obliquely inclined outward) of acetabular roof rather than normal horizontal orientation. Femoral head remains in the acetabulum
47
Developmental dysplasia of the Hip (DDH): Degrees: 2. Subluxation
Most common
Incomplete dislocation of hip, not complete dislocation, femoral head is in contact with acetabulum but it's partially displaced
48
Developmental dysplasia of the Hip (DDH): Degrees: 3. Dislocation
Femoral head loses contact with acetabulum and is displaced posteriorly and superiorly over the rim so femoral head actually slides completely out of socket
Ligaments are elongated and taut
49
Developmental dysplasia of the Hip (DDH): Clinical manifestations: Infant
Newborn: appears in a lax hip joint rather than an outright dislocation
Hip joint laxity
Shortened limb on affected side
Restricted abduction of hip on affect side
Unequal gluteal folds when infant prone
Positive Ortolani test
Positive Barlow test
50
Ortolani test
Used to confirm Barlow findings
| Thighs are abducted to test of subluxation and dislocation
51
Barlow test
Performed by adducting the hip bringing thigh to midline while applying light pressure on the knee and directing force posteriorly. Hip dislocates easily with this maneuver, then the test is considered positive
52
DDH: Early intervention
Longer the delay in treatment the more severe, more difficult treatment, and less favorable the prognosis is
Goal is to obtain and maintain a stable hip joint and promote normal hip joint development
53
DDH: Birth - 6 mo
Pavlik harness: maintaining abduction and flexion of the hip for about 3-5 months
Straps are checked and adjusted Q1-2 weeks due to rapid growth
54
Pavlik harness
there is one on each leg placed so that legs are held in important position to keep it stabilized during course of treatment
55
DDH: 6-24 mo
Dislocation unrecognized until child begins to stand and walk
Treatment: Closed reduction under general anesthesia, then placed in a hip spica cast for 2-4mo
If hip remains unstable: open reduction is performed
56
DDH: Older children
Operative reduction, include preoperative traction, or the performance of a tenotomy (surgical division of tendon), and possibly a hip osteotomy (surgical procedure where bones of hip joint are cit and reoriented and fixed back into a new position)
In older children, may have to perform more dramatic procedures to construct the acetabular roof. Correction after 4 yr is very difficult, not advised after 6yr
57
DDH: Nursing care
Teach parents to remove and apply harness appropriately
Only remove to check skin and bathing
Teach skin assessments, always put a shirt or onesie underneath the harness chest straps and put some type of long socks preferably up to the knees to prevent straps from rubbing against skin
Have parents check 2-3 x/day for any red areas under the straps
Provide gentle massage underneath the straps to stimulate circulation
Avoid any lotions, creams, ointments, or powder under the straps
Place diaper under the straps
Encourage cuddling to promote cognitive development and infant/caregiver bonding
58
Talipes equinovarus (clubbed foot)
Congenital abnormality in which the foot and ankle is twisted out of its normal position
Boys affected more than girls
Unknown cause
59
Talipes equinovarus (clubbed foot): Diagnostic evaluation
Deformity is apparent and detect prenatally through US or at birth
60
Talipes equinovarus: Described according to position of the ankle and foot
Talipes varus: inversion or bending inward (most common)
Talipes valgus: eversion or bending outward
Talipes equinus: plantar flexion with toes lower than the heel
Talipes calcaneus: dorsiflexion with toes higher than the heel
Most cases are a combination
Most commonly occuring being the composite deformity talipes equinovarus: foot pointed downward and inward in varying degrees of severity
61
Talipes equinovarus: Categories: Positional
Mild or postural and may correct spontaneously or necessitate some passive exercising or possibly serial casting. No bony abnormality but there could be tightening or shortening of soft tissue
62
Talipes equinovarus: Categories: Syndrome or teratologic
Often associated with other congenital abnormalities, usually necessitates surgical intervention, and with this there is a higher incidence of recurrence for these kids
63
Talipes equinovarus: Categories: Congenital
Its usually idiopathic, there is bony abnormality involvement and requires surgical procedure
64
Talipes equinovarus: Goal of care
Stretch the tightened tendons and ligaments gently and return foot to maximal anatomical position
65
Talipes equinovarus: Treatment stages
Correction of deformity
Maintenance of the correction until normal muscle balance is regained, and normal position is then achieved
Follow-up observation to avert possible recurrence
66
Talipes equinovarus: Serial casting/Ponseti method
Series of corrective casting and or use of splints, could even require surgical correction and series of cast to gently guide that clubfoot into position
Applies to hold foot in desired position
Begun right after birth, weekly manipulation and serial long leg cast to allow gradual repositioning
Extremities are casted and changed every 1-2 weeks until maximum correction is achieved usually 6-10wks
67
Talipes equinovarus: Casting: Nursing care
Cast care
Skin care
Education
Parental support
68
Talipes equinovarus: Casting: eduction
Parents need to understand the overall treatment plan, importance of regular cast changes and that they understand their role in overall effectiveness of therapy
Reinforce and provide instructions of cast care and skin care. Make sure parents know how to assess for any problems. They need to encourage normal G&D
69
Talipes equinovarus: Parental support
Parents understand their role
Active participation in the physical therapy treatments and child's strength program
Help the parents understand the time commitment involved in caring for these kids
Very large commitment that parents have to follow through with physical therapy and doing it on consistent basis as well as strengthening program
Assess parents ability to monitor the child adequately for complications and confirm they understand the signs and symptoms of the complications that they might need to call the provider
70
Osteogenesis imperfecta
"brittle bone disease"
A group of heterogeneous inherited disorders of connective tissue. Parents often have a family history but most cases are generally due to new mutation
Defective periosteal bone formation and reduced cortical thickness of bones
Hyperextensibility of ligaments
71
Osteogenesis imperfecta: Characterized by
Excessive fragility/fracture and defects of bones/bone deformity
72
Osteogenesis imperfecta: Type I
Procollagen: Mutation on the genes that affect type 1 collagen, results in bone mineralization, abnormal construction of bone, and susceptibility of fractures. Most common mild bone fragility and may see kids have blue tinged to sclera, teeth usually look normal and may have some mild hearing loss
73
Osteogenesis imperfecta: Type II
Most lethal, results often in stillbirth or death in early infancy, it is a severe bone fragility with multiple fractures that may occur at birth, autosomal recessive inheritance
74
Osteogenesis imperfecta: Type III
Severe bone fragility (most cases), leading to severe progressive bone deformity, might have normal sclera, but will see very marked growth failure. Most autosomal recessive inheritance, some may be autosomal dominant
75
Osteogenesis imperfecta: Type IV: A
Mild to moderate bone fragility, normal sclera, short stature, variable deformities, autosomal dominant inheritance
76
Osteogenesis imperfecta: Type IV: B
Same as A but with abnormal dentition/teeth called dentinogenesis imperfecta
Represent about 6% of cases
77
Osteogenesis imperfecta: Type V
Similar to type IV may have hyperplastic callus and negative collagen mutation
78
Osteogenesis imperfecta: Type VI
Moderate to severe bone fragility
79
Osteogenesis imperfecta: Type VII & VIII
Osteochondroplasia and short stature
80
Osteogenesis imperfecta: Therapeutic management
Primary supportive care
IV bisphosphonate therapy, may need Calcium, GH.
No matter what fractures will occur
Children who get fractures from non-traumatic accidents need to be screen
Rehabilitative approach: (positional contractures and deformities, muscle weakness and osteoporosis, misalignment of lower extremity joints)
81
Osteogenesis imperfecta: Nursing implications
Careful handling
Changing diaper or tying a tourniquet can cause a fracture
Support when turning, positioning, and moving them
Educate parents on limitations and planning suitable activities to promote optimum development and to protect these kids from harm
82
Osteogenesis imperfecta: Clinical features
```
Weak bones, susceptible to fractures
Scoliosis
Kyphosis
Blue tint to sclera (type 1)
Early hearing loss (type 1)
Hypermobility in joints (all)
Hypoplastic discolored teeth (type IV B)
```
83
Scoliosis
Most common spinal deformity
Abnormal curvature of the spine
May be congenital or develop during childhood, many potential causes, most are idiopathic
Becomes noticeable after per-adolescent growth spurt, clothes may be ill fitting
Hips are slightly higher than the other
School screening, need to catch as soon as possible
84
Scoliosis: Causes: Idiopathic
Infantile, childhood/juvenile, adolescents (most common time of diagnosis)
Progresses faster in girls, and will more likely need surgical treatment
Becomes noticeable after pre adolescent growth spurt
85
Scoliosis: Secondary Cause: Neuro
Tethered cord
Cerebral palsy
Muscular dystrophy
Spinal tumor
86
Scoliosis: Secondary cause: MSK
DDH
Leg length discrepancy
OI
87
Scoliosis: Diagnostic
Based on Xray or observation
Assessment performed: standing behind the patient (should be in undergarments)
Asymmetry of shoulder height, scapular or flank shaped shoulders, or hip height and alignment should all be noted
Child bends forward and arms hanging, you'll see asymmetry
Scoliometer used to determine the angle of trunk rotation
Radiography/Xray used to determine the degree of curvature
88
Scoliosis: Assessment findings
Trunk asymmetry
Unevenness of shoulders
Prominent scapula or uneven height of scapula
Rib hump
Uneven hips
In addition to primary curvature, compensatory curvature often present that aligns head with gluteal cleft
89
Scoliosis: Therapeutic management
Team approach (ortho, neuro, PT, nurses, social work)
Children should be observed regularly by provider and receive routine xrays for evaluation
Options are based on the magnitude of curve, location, and type of curve
Bracing or surgical intervention
Sometimes exercise
90
Scoliosis: Other factors to determine treatment
Age, skeletal maturity, and other underlying conditions
Growth plates closed?
Whats the degree?
Is the child going to grow more?
If growth plates are closed then its sure that the pt wont grow anymore and the curvature wont increase
91
Scoliosis: Bracing
Not curative, but may shol curvature down in order to allow for skeletal maturity. Compliance is a problem because teens are concerned with appearance so that can make them feel very awkward
Most common braces: Boston, Wilmington, which are customized, pre-fabricated plastic shells.
Used for moderate curvature
92
Scoliosis: Surgical intervention
Severe curvature (instrumental and fusion)
Greater the 30-40 degree require fusion
Involves realignment with in an internal fixation and bony fusion of the realign spine
Variety of rods that may be used during surgical fusion (most common: Harrington, Luque)
Posterior spinal fusion is best choice for thoracic curves.
Anterior spinal fusion is the best treatment for lumbar curves.
93
Scoliosis: Exercise
May be prescribed but really rarely of any value in managing scoliosis but can maintain and strengthen abdominal muscles to provide support
94
Scoliosis: Care management
Concerns of body image is the priority psychoscolcial nursing diagnosis for the adolescent. Explain the importance of the benefits
95
Scoliosis: Pre-op teaching for spinal fusion
What to expect before and after surgery
Demonstrate how to use incentive spirometer, coughing , and deep breathing
Show them all the equipment that might be used: foley, IVs chest tubes, O2 mask
Teach them about the PCA pump and explain it is for their pain
Demonstrate how to log roll and how to assist them out of bed
96
Scoliosis: Post-op Care for spinal fusion
Make sure child maintains airway, do neurovascular assessment of lower extremities, log roll every 2 hours depending on orders
Typically they will be out of bed and ambulating at least 4 times a day
Most of the time adolescent so we want to encourage them doing ADL they usually do, start ambulating post op 2-3 days
97
Scoliosis: Family issues
Provide resources and information on support groups
| Family is encouraged to become involved so that they will be comfortable caring for them at home
98
Osteomyelitis
Infection of the bone that can occur at any age, when in children more frequently at the age of 10 and younger
Boys more than girls
Caused by exogenous or hematogenous sources
99
Osteomyelitis: Most common causative agent
Staphylococcus aureus
| Group B strep in neonates
100
Osteomyelitis: S/S
Begin abruptly and resemble symptoms of arthritis and leukemia
Starts off with severe pain, fever, irritability, tenderness to the area, limited ROM, swelling over the area, and pain with movement
101
Osteomyelitis: Diagnostic
Blood cultures to identify organism and abx susceptibility
MUST TREAT THE BACTERIA
Bone cultures obtained from biopsy is rare but will happen if the blood culture is inconclusive
Supportive evidence: marked leukocytosis, elevated ESRT, C-reactive protein
Xray
Bone scan
MRI - most definitive test and most sensitive diagnostic tool
102
Osteomyelitis: Xray
May appear normal at first, may take up to 2 -3 weeks for signs to become evident
103
Osteomyelitis: Bone scan
Shows areas where there is increase blood flow which can occur in early stages of infected bone and that can be useful in locating multiple sites
Not diagnostic
104
Osteomyelitis: Types
Acute hematogenous
Exogenous
Subacute
Chronic
105
Osteomyelitis: Acute hematogenous
Blood borne infection that goes on to cause infection in bone
106
Osteomyelitis: Exogenous
Acquired directly from puncture wound, open fracture, surgical contamination, or from tissue infection from adjacent wound.
107
Osteomyelitis: Subacute
Longer course
| Caused by less virulent microbe that created a walled off type abscess that typically in the tibia
108
Osteomyelitis: Chronic
Progression of acute Osteomyelitis, characterized by dead bone, bone loss, drainage as well as the development of sinus tracts in the bone
109
Osteomyelitis: Management
```
IV abx
Education
Surgery
Pain management
Monitoring
```
110
Osteomyelitis: Presentation
May be subacute, with walled-off abscess rather than spreading infection
111
Osteomyelitis: IV abx
```
#1 priority
Prompt, vigorous IV abx for extended period of time (3-4wk up to several months)
```
112
Osteomyelitis: Treatment for S. aureus
Nafcillin, clindamycin
| Nurse should advocate for a PICC line as soon as Osteomyelitis is diagnosed because of long term abx therapy
113
Osteomyelitis: Educate parents
IV administration, typically because kids are sent home for home care with PICC lines. Make sure parents know how to set those up and set up flushed. When one dose, have to draw up flushes.
114
Osteomyelitis: Surgery
Necessary if there is no response tot specific abx, if there is a penetrating injury, or if the infection spreads to the joint
115
Osteomyelitis: Pain management
Movement can cause severe discomfort. Position in a comfortable position with affected bone or limb supported
No weight bearing
Long term pain meds may be needed
116
Osteomyelitis: Monitor hematologic
Renal and hepatic responses to treatment
| When using abx, need to monitor renal and liver function and see how they are responding
117

Moderate impairment: 85% will go on to achieve ambulation
30-50% with CP will develop cognitive impairments
Growth can be affected, their survival depends on any comorbid conditions that they may be experiencing
136
Cerebral Palsy: Characterized by
Abnormal muscle tone and coordination
137
Cerebral Palsy: Causes
Prenatal brain abnormalities (exact cause is unknown, can be genetic or other prenatal birth abnormalities)

Cerebral Palsy: Types
```
Dependent on where the brain is damages
Spastic
Dyskinetic
Ataxic
Mixed
```
141
Cerebral Palsy: Spastic
Most common
Muscles appear stiff and movement are very stiff and jerky
Spasticity is a form of hypertonia or increased muscle tone
Both groups of muscles will turn on at the same time and in some instances the wrong group turns on making movement difficult or impossible (only one specific group should turn on at a time)
142
Cerebral Palsy: Dyskinetic
Variable movements that are involuntary.
Uncontrolled movements become very noticeable when they try and move
Movements can be a twisting or repetitive movement to the trunk or from extremities called Dystonia
Slowed movements called Athetosis/Athetoid
Dance like jerky irregular unpredictable movement is Athetoid, involuntary jerky slow worm like movements
Muscles involved are extremities, trunk, facial muscles, and tongue

Careful assessment
Good history and physical
Talking to parents, assessing for developmental milestones
Head lag when you pick them up, ask the parents if the baby feels stiff when being picked up or feel floppy, should not feel floppy as they get older
Cradled in arms: does the child overextend the neck or back or feel like they are pushing away from you?

Support family
162
Neural tube defects
Largest group of congenital anomalies
163
Neural tube defects: Normally
The spinal cord and cauda equina are encased in a protective sheath of bone and meninges during development
164
Neural tube defects: Failure of neural tube closure during development
Produces defects of varying degrees may involve entire length of neural tube or be restricted to a small area
165
Neural tube defects: Incidence
Occurs more often in White and Hispanic children, studies have shown that it may be due to Hispanic diet.
They are less likely to take folic acid supplements and folic acid are known to help reduce neural tube defects
Supplementation may not be as protective in overweight woman according to some studies, this is important for Hispanic women because they 1/2 times more likely to give birth to a baby with spina bifida or neural tube defects
166
Neural tube defects: Types
Anencephaly
Myelodysplasia
Spina bifida occulta
Spina bifida cystica
167
Anencephaly
Congenital malformation where both of the cerebral hemispheres are absent
Condition is basically absence of brain. Incompatible with life, even if infant had some brain and is able to control temp, cardiac, and respiratory function, the may live for a few hours to weeks but eventually die from respiratory failure
168
Myelodysplasia
Any malformation of spinal canal and cord
| Failure of the bony spine to close is termed spina bifida (2types)
169
Spina bifida occulta
Defect not visible externally, occurs most frequently in lumbosacral area, not apparent unless other associated manifestations or neuromuscular disturbances
Mild form of SB that many people aren't aware they have. Outer part of vertebrae are not completely closed, the splits are so small that the spinal cord does not protrude. The skin at site and lesion may be normal or may have small hairs growing from it. May be a dimple in the skin or birthmark
170
Spina bifida cystica
```
Visible defect and usually occurs with external sac like protrusion
2 forms (Meningocele, Myelomeningocele)
```
171
Spina bifida cystica: Meningocele
Encases meningeal and spinal fluid and not neural elements involved
172
Spina bifida cystica: Myelomeningocele
Contains meninges, spinal fluid and nerves, usually associated with varying degrees of neurologic deficits
173
Neural tube Defects: Patho
Failure of the neural tube to close during the embryo's early development (3-4weeks after conception). Some vertebrae and spinal cord do not fully formed and remain unfused and open. If opening is large enough then can cause some spinal cord to protrude through opening of those bones. There may not be a fluid filled sac that surrounds the spinal cord. May be genetic. Degree of neurologic dysfunction the child will experience depends on where the sac protrudes through the vertebrae, level of defect is, and amount of nerve tissues involved
174
Neural tube Defects: Patho: Multifactorial causes
Drugs, radiation, maternal malnutrition, chemical exposure, genetic mutation
175
Neural tube Defects: Patho: Additional causative agents
Maternal obesity
Maternal Dm
Low vitamin B12 level
176
Neural tube Defects: Prenatal detection
Elevated alpha-fetoprotein level in amniotic fluid at 16-18 wk gestation
Uterine ultrasonography
Chorionic villus sampling (CVS) can be done first. Not recommended before 10 wk of gestation because the CVS carries certain risks
177
Neural tube Defects: Clinical manifestations
Hydrocephalus associated with spina bifida, flaccid paralysis of lower extremities, absence of deep tendon reflexes, lack of response to pain, presence of constant urinary dribbling
178
Neural tube Defects: Therapeutic management: Postnatal care
Prevention of infection, performing neurological assessment, observing for abnormalities, dealing with the impact that it might have on the patient and family
Early closure of meningocele, typically with in the first 24-72 hr of life, favorable outcomes.
If sac is leaking then closure if recommended even earlier (24hr)
179
Neural tube Defects: Therapeutic management: Shunt
Provide some relief from progressive hydrocephalus
Early surgical closer if myelomeningocele sac, pre-fetal birth surgery can reduce the need for placement of shunt
Can shoe improvement of mental and motor function
180
Neural tube Defects: Therapeutic management: Orthopedic considerations
Prevention of joint contracture, correction of existing deformities if possible, prevention or minimization of motor and sensory deficit, want best possible function of lower extremities.
Skin care is important with use of braces, walking devices, wheel chairs
181
Neural tube Defects: Therapeutic management: Of GU function
Myelomeningocele is a common cause of neurogenic bladder which is lack of bladder control due to nerve innervation that causes them to lack bladder control
Predisposes the child to UTI because of not emptying the bladder completely
Might need intermittent catheterization
Teach parents how to do it and eventually taught the child when they are older
182
Neural tube Defects: Therapeutic management: GU Goal
Preserve renal function and manage the urinary incontinence
183
Neural tube Defects: Therapeutic management: GU surgical procedure
Vesicostomy- bladder is surgically brought out to the abdominal wall to allow continuous drainage
Appedovasacotomy- where catheterized channels is created from appendiz, ureter or bowel so catheter can be inserted through the channel. This is done when kids get older around 10 because they are old enough to use this to perform a self-catheterization, and it fosters independence
184
Neural tube Defects: Therapeutic management: Latex allergy
Risk for allergy is highest with spina bifida
Always place on a latex allergy precaution
Food items: bananas, kiwi, avocado and nuts
Educate the child and parents
Advocate for an Epipen
185
Neural tube Defects: Therapeutic management: Bowel control
Some degree of fecal continence may be achieved with regular bowel habits
186
Neural tube Defects: Prognosis
Depends on extent of neurological deficit and early surgical repair, preventing infection and correcting hydrocephalus. Many are intelligent and will achieve independence. Remember coordinated care is important
187
Neural tube Defects: Emergent nursing care
Prevent trauma to the membranous cyst, usually baby us placed in incubator or warmer to maintain temp. Avoid rectal temps can cause irritation and prolapse, sphincter function is effected.
Before surgical closure, prevent from drying out by covering with a sterile moist non-adherent dressing, usually sterile NS. When changing dressing look for leaks, abrasions, irritations and signs of infection. Carefully clean if soiled/contaminated
Look for signs of ICP: monitor FOC Q2H
Keep baby prone, no clothing or covering because don't want to irritated it.
Turn baby head Q2H
188
Neural tube Defects: Post-op care
Monitor VS, I&O, provide nutrition through OG, NG, TPN, or PO if able to
Prone right after surgery or side lying
Close observation for any CSF leak
Monitor for signs of infection, and pain
Ventriculoperitoneal Shunt: FOC measurements, signs of increased ICP, careful with positioning of head
Bladder surgery: Look for signs of infection, make sure its healthy, no unusual odor or drainage. (want pink,no bleeding)
Orthopedic surgery
189
Neural tube Defects: Prevention
Supplementation of folic acid: 0.4mg/day begin before conception
Food that have folate: Green leafy veggies, citrus, fortified foods (rice, grits, pasta, breads,)
If history of neural tube defects take 4mg/day
190
Duchenne muscular dystrophy
"pseudohypertrophic muscular dystrophy"
Most severe and most common of muscular dystrophies in childhood
X-linked recessive inheritance pattern, 1/3 of cases results from fresh mutations and mother is not a carrier
191
Duchenne muscular dystrophy: Characteristics
Most kids reach their appropriate early developmental milestones, but evidence begins to occur in early childhood (3-5yr)
Difficulty running, climbing stairs, riding the bike
A progressive of muscle weakness, wasting contractures then begin
Hypertrophic calf muscles occur in most patients due to enlargement from fatty infiltrations occur- feels firm or woody
Progressive generalized weakness
Death from respiratory or cardiac failure between 15-30
192
Duchenne muscular dystrophy: Diagnostics
Prenatal diagnosis is possible as early as 12 weeks of gestation
Made through PCR where they look for dystrophic chain gene mutation
Confirmation of diagnosis by electromyography, muscle biopsy (reveal fatty fibrous tissue that gradually replaces muscle, protein dystrophin is low in muscle of these patients) and serum enzyme measurement
Positive family history and display of the usual characteristics of the disease
193
Duchenne muscular dystrophy: Clinical manifesations
First sign: delayed walking, tired easily, difficulty running, climbing, riding bike
Waddling gait, frequent falls, gower sign (characteristic sign of rising up from squatting or sitting position from the floor)
Lordosis from weaken pelvic muscles
Progressive symmetric muscle wasting that occurs
Enlarged or hypertrophic muscles, especially in thighs and upper arms
Profound muscular atrophy in later stages
Mild to moderate mental impairment
Obesity is common (contribute to premature loss of ambulation, and restricted because of dystrophy, and physical activity, become bored and end up consuming more calories )
Diet needs to be closely monitored
Deficiency of dystrophin isoforms in brain tissue is what causes cognitive mental impairment
194
Duchenne muscular dystrophy: Therapeutic management
No effective treatment
Keep child as active as possible: ROM exercises, bracing, performance of activities of daily living, surgical release of contractures as needed
Maintain vital lung capacity, surgery to release and muscle contractures or deformities, help them in their performance of ADLs
Ensure the child gets all vaccines due to a risk of respiratory infection, everyone around the child needs vaccines also. Avoid anyone who has a respiratory infection
Develop abnormal breathing patterns= inadequate oxygenation
Long term ventilation may be required
Genetic counseling for family
195
Duchenne muscular dystrophy: Goal
Maintain function in unaffected muscles (ambulations and independence as long as possible)
196
Duchenne muscular dystrophy: Care management
Multidisciplinary team helps child and family cope with chronic, progressive, debilitating disease
Design program to foster independence and maintain activity as long as possible
Teach child self-help skills
Provide appropriate health care assistance as child's needs intensify
Take care of their skin and family as well because they can be immobilized or with assistive devices that can cause problem for their skin
Maintain some sort of bowel and bladder functioning and protect them from respiratory infection
Diet monitoring to prevent obesity
197
Guillain-Barre syndrome
Infectious polyneuritis
Acute demyelinating polyneuropathy with progressive flaccid paralysis
Occurrence in children is rare but happens between 4-10y/o
Child's own immune system begins to damage their nerve cells, causing muscle weakness, which then leads to paralysis
Symptoms that can last for a few weeks. Most people fully recover but some people may be left with serious nerve damage. Rare occasions people have died from this disease, death occurs due to difficulty breathing
198
Guillain-Barre syndrome: Hallmark
Acute peripheral motor weakness. Occurs after 10 days after a nonspecific viral infection. Very rare occasion been reported after administration of certain vaccines, usually the influenza vax.
199
Patho of acquired neuromuscular disorders
Immune-mediated disease
Associated with viral or bacterial infections or administration of vaccines
Inflammation and edema in spiral and cranial nerves: progresses to impair nerve conduction and the produces partial or complete paralysis of muscles innervated by involved nerves
200
Patho of acquired neuromuscular disorders: Associated with
Infectious mononucleosis, measles, mumps, gastroenteritis, cytomegalovirus, Epstein barr virus, H. pylori, lyme disease
201
Guillain-Barre syndrome: Diagnostic
Based on paralytic manifestations, electromyographic findings or both
CSF analysis: may have increased protein concentrations; other lab tests results may be within normal limits
Symmetric nature of paralysis helps differentiate from other diagnosis
202
Guillain-Barre syndrome: Clinical manifestations
Very rapid onset
Begins with flu like symptoms
Initially: muscle tenderness, sore throat, paresthesia, muscle weakness
Weakness progresses to paralysis: may be ascending or descending, rapidly ascending from lower extremities; may involve trunk, arms, and face
Flaccid paralysis with areflexia which is a loss of reflexes
Intercostal and phrenic nerve involvement (breathlessness, vocalization and shallow and irregular respirations may be noted)
Urinary incontinence or retention and constipation (recovery of function usually begins 2-4wks after the progression stops)
203
Guillain-Barre syndrome: Therapeutic management
Treatment: symptomatic
Hospitalized in the acute phase due to respiratory involvement that may require ventilation assistance or even the use of a temporary trach tube
Treatment is acute phase is aggressive (IV steroids, IV immunoglobulin, plasmapheresis)
Respiratory support
Medications to prevent complications
Most patients may make full recovery in several weeks but it can take up to several months
204
Guillain-Barre syndrome: Acute phase
When the symptoms begin until new symptoms stop appearing; may last for as long as 4weeks
205
Guillain-Barre syndrome: Plateau phase
Symptoms remain constant without deterioration and may last from several days up to a few weeks
206
Guillain-Barre syndrome: Recovery phase
Patients begins to improve and progress on to their optimal recovery period
207
Guillain-Barre syndrome: Course and progrosis
Better outcomes are associated with younger ages
| Muscle function begins to return 2 days- 2 weeks after onset of symptoms, but period to complete recovery is prolonged
208
Guillain-Barre syndrome: Care management
Supportive care
Observation for early signs of respiratory distress/difficulty swallowing (NPO, NG/G tubes)
Maintain an open airway with suctioning; postural changes to prevent pneumonia; monitoring O2 status
Temporary urinary catheter
Prevention of complications (prevent muscle or joint contractures so nurse or PT may provide passive ROM)
Pain management (Neurontin)
Physical therapy (passive ROM in the acute phase, later in the recovery phase: active therapy may be indicated)
Support for child and family
209
Down's syndrome
Most common chromosomal abnormality
Decreased muscle tone, which can begin to compromise respiratory expansion. The underdeveloped nasal bone also causes inadequate drainage of mucus
Caused by an extra chromosome 21 = trisomy 21
The degree of cognitive and physical development is related to the percentage of cells with the abnormal chromosomal makeup
210
Down's syndrome: Caused by
Translocation of chromosomes 15,21,22
| Associated with advanced maternal age >35
211
Down's syndrome: Physical features
```
Separated sagittal sutures
Brachycephaly (short head)
Flat occiput
Inner epicanthal fold of the eye
Specking of the iris (Brushfield spots)
Small nose with the depressed nasal bridge
Small ears (conductive hearing loss)
High arched palate
Protruding tongue
Delayed eruption of teeth
Excessive neck skin folds (detected on prenatal ultrasound)
Neck laxity
Very short broad neck
Pectus excavatum (sunken chest)
Pectus carinatum (pigeon chest)
Congenital heart defects
Round protruding abdomen
Umbilical hernia
Small penis
Cryptorchidism
Bulbous vulva
Broad short hands with stubby fingers and transverse palmar crease
Plantar crease between the big and the second toe
Broad short feet with stubby toes
Short stature
Hyperflexibility
Muscle weakness
Hypertonia
Atlantoaxial instability
Dry cracked fissuring of skin
Mottling of skin
```
212
Down's syndrome: Brushfield spots
White dots ringing the iris
213
Down's syndrome: Considerations
Speech, PT, OT: to promote the child's optimal development
| Give the family reassurance and resources and tell them about support groups
214
Down's syndrome: Higher risk for
```
Strabismus
Leukemia
Cardiac defects
Obesity
Respiratory infections
Hearing and vision loss
Hypothyroidism
```
215
Down's syndrome: Atlantoaxial instability
Increased mobility at the articulation of the 1st and 2nd cervical vertebrae
Most of the time it is something that is asymptomatic. Some who have it have normal x-ray and then have an abnormal x-ray following, some who have it have abnormal x-rays then have normal x-rays following
All children with Down's who want to play sports should have a cervical spine x-ray to check for this (if negative then no need for more x-rays)
Children who do not have instability should be encouraged to participate in any sports they want
216
Down's syndrome: Atlantoaxial instability: Cause
Not well understood but it may be an abnormality of the ligament which maintains the articulation, could also be from bony abnormalities of the cervical vertebrae... could be both
217
Down's syndrome: Hypotonicity of muscle and Hyperflexibility of joints
Complicate position of children
Limp, flaccid extremity resembles posture of ragdoll so holding the infant can be difficult
Extended body position can also promote heat loss so parents should be encouraged to swaddle or cover the infant before picking them up
Decreased muscle tone compromises the respiratory expansion, and affects gastric motility- predisposing the child to constipation
Increase fiber and water to prevent constipation
