Q

What positioning do we put infant in for meningocele and myelomeningocele?

Why does surgery take so long?

A

Prone position or on tummy to keep them from rolling onto the sac until recovered

Surgery can only happen 16-18 hours later bc they hav to to know the extension of the problem
- how much tissue, nerves, other defects (bc midline defects means other defects are likely)

90 degree angle and raised leg that causes pain and occurs with meningitis

40
Q

What will happen to glucose and protein if it is bacterial meningitis?

What else will they culture?

Testing?

A

Glucose will drop
Protein rises if the cause was bacterial

Will culture blood and urine

Rapid antigen testing

41

We isolate them and we get treatment for anyone who has been in contact with them.

45
Q

What treatment do we start out with if meningitis is suspected?
Next?

A

Broad spectrum IV antibiotics first but then narrow it down after lumbar puncture is done and we know the organism
- lumbar puncture being cloudy is not god

46
Q

What position do we keep those wit meningitis in?

A

Elevated to help drain the fluid from the head

47
Q

What precautions will someone with meningitis be on? meds?

A

Isolated but also seizure precautions with anti-seizure meds

- headache may be present too

48
Q

With antibiotics administration what do we want to give before? Why?

A

Steroids like dexamethasone as to avoid inflammation and ICP from Cytokine Cascade

The antibiotics may break down the cell wall and allow fragments of the membrane to to cause inflammation

49
Q

How can we prevent meningitis?

How can meningitis effect the elderly?

A

Vaccinate
- especially young and elderly

They’re already at risk from reduced motor skills, hearing, and cognition issues. We don’t want any secondary effects occurring from the meningitis.

Encephalopathy characterized by viral infection that can lead to hepatic, metabolic, neuro failure

Using aspirin - so don’t give this to kids. Salicylates

53
Q

What is Guillain Barre’ ?

A

Progressive motor weakness that travels upwards due to infection from the nerves being affected
- bottom peripheral and distal affected first like legs

54
Q

Major concerns with Guillain Baree?

A

Respiratory depression bc it affects breathing muscles

Fall risk bc it starts from bottom and goes up

55
Q

What is recommended for Guillain Barre patients?

When is another Time Guillain barre can also happen?

A

PT to learn how to use muscles again

Post pregnancy due to hormones shifting

56
Q

What is the major thing to remember about treating head injuries?

A

We aren’t treating the head injury but we are preventing the secondary injury

57
Q

T/F

Having a seizure means you have epilepsy

A

False. To be an epileptic, you must have 2 or more seizures that are not caused by anything else
- bc you can have seizures

58
Q

Classifications of seizures

A

Focal : Limited area in the brain with abnormal firing but there are seizures taking place . Motor response is not always involved though so may not even see it and can be simple with motor signs, sensory signs, impaired awareness.

Generalized : Abnormal firing in a large area such as a whole hemisphere of the brain and there is a muscle response that can be seen that result in Tonic or Clonic responses.

59
Q

Tonic Generalized Seizure

Clonic Generalized Seizure

A

Stiffening up for 10-20

Stiffening with jerky movement

60
Q

What is meant by Post stage seizure?

A

Stage where the effects go on

61
Q

Focal seizure that is partial with motor signs

A

A seizure of the a limited area of the brain due to it being focal
And Small response like lip smacking or hand smacking. and it appears on one side

62
Q

Focal seizure that is simple partial with sensory signs

A

Limited area of the brain seizure that produces sensory issues like numbness, paresthesia, or pain in one area of the body.
Posture change from muscle relaxation and visual sensations

63
Q

Focal seizure with impaired awareness

What will you have?

A

Period of altered behavior
Can have auras and impaired consciousness.
You won’t remember it.

64
Q

T/F

Generalized seizures or seizures that happen in large areas are always either tonic or clonic.

A

False!

It can be both called a Tonic-Clonic generalized seizure and be followed be a postictal phase

65
Q

In a tonic clonic seizure, how long does each portion last

A

Tonic for 10-20 seconds
- stiffening contractions and often may fall to the ground

Clonic for at least 30 seconds but can last half or longer
- you will see violent jerking movement from rhythmic

66
Q

Explain the tonic phase

A

Immediate loss of consciousness, falls to ground even.
Eyes roll upward
Not breathing, apnea
Increases salivation not swallowing

67
Q

Explain the clonic phase

A

Violent jerking
Foaming at mouth
Incontinent urine and feces

68
Q

Postical phase

A

Appears relaxed, but is semiconscious or confused with poor coordination.

  • not out of the woods
  • very sleepy
69
Q

What are generalized absence seizures?

When do they go away?

How often can these happen?

A

Unrecognizable seizures almost that happen to kids 4-12 years old that is mistaken for inattentiveness or daydreaming
- the seizure Vetter discussed

Go away with puberty

Absence seizures can happen multiple times throughout the day 20 or more

70
Q

What are Atonic and Akinetic generalized seizures

When do these happen a lot tho?

Can you outgrow these?

A

Sudden abrupt momentary loss of muscle tone
You fall without the ability to break the fall essentially and can happen anytime in the day

Can happen shortly after being awake

Yes they can be outgrown

71
Q

What are Generalized Myoclonic seizures? Important thing to differentiate?

Is there a postictal state with Myoclonic seizures?

Do you lose consciousness with Myoclonic seizures?

Is it symmetric?

A

Sudden brief contractures of muscle that can be once or continuous.
- not a jerky movement but a contraction

No postictal state

You can or can’t be unconscious

It can or can’t be symmetric

72
Q

Where do they start with diagnosis of seizures?

A

A very thorough history and physical

- can even include prenatal care

73
Q

When a skilled observation of a seizure is happening (usually to help dx) what is needed?

A

Full description of what is happening , location, consciousness level, type, and how long it lasts
- document carefully

74
Q

What is the most useful tool for diagnosing seizures?

A

EEG

  • confirms abnormal electrical discharges
  • helps focus in on what type of seizure
75
Q

Why is the keto genie diet recommended for seizures?

A

The high fat, low carbs, and low protein induces keto to keep seizures at bay

76
Q

What is surgery like for seizure treatment?

A

Remove any area that interferes with electrical firing of brain or separate hemispheres; removal of epileptic foci

77
Q

How are vagal nerve stimulator a good option for management of seizures?

Programing?

A

The stimulator goes in the chest/collarbone, wires wrap around legs and vagal nerve, and then the single overrides the seizure

Programming can be continuous for 30 sec every 5 minutes or activated for demand of the seizure

78
Q

Vagal nerve stimulator complications?

A

Coughing, swallowing hoarseness
Infection
Tingling

All from excessive stimulation

79
Q

Larzepam use?

A

Most common seizure med and used in emergencies

80
Q

Diazepam use?
route?
What do we need to do for this med so it work properly?

A

Can be given rectally for seizures

Make sure to dilute with saline tho bc it can sticking interact to plastic

81
Q

Seizure meds that start with a P?

A

Phenytonin

Phenobarbital

82
Q

What can seizure meds interact with?

A

Liver issues
Bone marrow
- RBC/WBC development

83
Q

What are Febrile seizures?

What age group is this most common in?

A

Seizure activity related to fever above 100.4-102

Infant - 5 years

84
Q

Management for seizures including febrile?

A

Put the child on their side

Do not try to put anything in the mouth or restrain the child

85
Q

When to seek medical attention with febrile seizures?

A

If seizures are repetitive
Last longer than 5 minutes
Child is difficult to arouse after the seizure
- the child may be tired but you should be able to arouse them

86
Q

What to educate parents about febrile seizures
