Q

young child fell on his head and experienced LOC followed by irritability, lethargy, bulging fontanelle and vomiting. Upon seeing him in the ED you immediately you order a CT exam. Results indicates diffuse blood spread in crescent shape. Dx? and what is the etiology? concern?

A

dx: subdural hematoma
etiology: tearing of VEINS resulting in low pressure bleed that separates arachnoid from dura.
concern: Bad bc crosses suture lines so blood can spread, swell –> death, coma, LT effects if not treated. Poor prognosis

tx open nondisplaced fx
PO antibiotic, repair laceration, splint, ortho FU
26
deformed/displaced fx tx?
make sure to check neurovascular structures, will require closed/open reduction, possible fixation (ortho ED consult)
27
standard tx for all fx?
always document neurovascular status before and after splinting or reduction to any fx (cap refill, nerve sensation) splint, pain control, ortho f/u
28
common fx to suspect child abuse
spiral fracture of long bone, femur fracture, spinous processes, acromion, skull fracture greater than 3 mm, posterior rib fracture, corner fracture or bucket handle from jerking/shaking (metaphyseal fracture)
29
child comes in guarding arm, holding it in slightly flexed prone position and will not use the arm even to grab candy. Normal radiographs. dx and tx?
dx: nursemaids elbow tx: reduction by immobilizing elbow, applying pressure to radial head, supinating forearn and flexing elbow - should feel pop * do not reduce without xray clearance
30
Acute septic arthritis presentation, cause, labs
presentation: fever, constant worsening joint pain, arm swollen joint pain with ROM *hip typically flexion/external rotation cause: adolescent = N gonorrhea, kids = s aureus or strep Lab: CBC< CRP, ESR, blood culture, joint aspiration
31
tx for acute septic arthritis if not treated, this may lead to?
* antibiotics (empiric then targeted) * repeated aspiration if peripheral joints or surgical drainage for hips/shoulders (ususal**) untreated --> osteomyelities
32
Kid comes in with fever, bone pain, swelling, and is guarding limb that began over a week ago. Pain in leg upon palpation. Xray (2 wks after initial onset) reveals bone destruction. MRI (the best study in this scenario) reveals marrow edema, abscesses. Dx, etiology, tx?
Osteomyelitis etiology: hematogenous spread of infection into BONE cause bone destruction in long bone tx: IV antibiotic (empiric then targeted), surgical drainage, debridement, hyperbaric O2 (to help with tissue healing)
33
this disease commonly affecting 18mth to 2 yrs has unknown etiology, but commonly follows URI, strep or trauma. Sx include abrupt onset pain to hip/thigh or knee, temp but FROM. WBC and ESR is normal and Xray shows some effusion. Dx, tx?
dx: transient synovitis tx: pain relief, obs, f/u *dx of exclusion, comes on quickly
34
6 year old BOY is limping and holds hip internally rotated with limited abduction but has little to no pain. How to dx and likely dx? etiology, tx?
Legg Calve Perthes disease dx: xray (AP and frog leg lat), bone scan, ortho referral URGENT etiology: idiopathic avascular necrosis of femoral head (no blood supply, bone dies), slow onset **think frog LEGG calve
35
this disease has similar presentation as Legg Calve Perthes but affects males 14-16 more freq. Associated with obesity, increased ht, genital underdev, pituitary tumors. Sx are acute or chronic hip/knee pain and xrays reveal ice cream falling off cone.
dx: SCFE (slipped capital femoral epiphysis) - -> femoral head slips and exposes anterior/superior aspects of femoral neck tx: bed rest with traction but most require surgery
36
toxidromes are helpful in categorizing reactions. Name the main ones
Anticholingeric (hot as haire, dry as a bone, red as a beet, blind as a bat; tachycardia) - benadryl is pink and could look like candy cholinergic (bradycardia), hallucinogenic, opiate/narcotic, sedative/hypnotic, sympathomimetic
37
poison control phone number
1-800-222-1222
38
what is the most important thing to know! deadly in a dose (1-2 tab can kill)
the substance! ASA, Ca chan blockers, oils, clonidine, iron (vit, birth control), chloroquine, methadone, nicotine, TCA, lindane, methyl salicylate
39
tx
stabilize ABC, contact poison control, DDD (disability/supportive car, drugs/antidotes, decontaminate)
40
Decontamination - ocular, skin, GI, blood stream
ocular (IRRIGATE saline lavage, flush till pH normal via litmus paper, alkali is worse than acidic); skin (normal saline flush), blood stream (antidote) GI (lavage, charcoal, cathartics, whole bowel irrigation, enhance elim - diuretics, dialysis, hemoperfusion, urine, charcoal)
41
GI decontamination methods
Ipecac only if within 30 min, gen not rec Gastric lavage - rarely; use for TCA CCB, iron, EtOH cathartics - not usually whole bowel irrigation - sustained release med charcoal - deox simple dilution for mild toxin
42
antidote for: acetaminophen
acetylcysteine
43
antidote for: anticholinergic
physostigmine
44
antidote for: benzodiazepine
flumazenil
45
antidote for: beta blocker
glucagon
46
antidote for: ca channel blocker
calcium
47
antidote for: digoxin
digibind
48
antidote for: heavy metals
chelation
49
antidote for narcotics/opiates
naloxene/narcan
50
if you don't know what poison was ingested..
draw lab for acetaminophen bc worse C metabolic panel (electrolyte level, kidney function, liver), coags (liver function), ABG, protein administer antidotes empirically as indicated by exam; you will do less harm by administering antidotes then letting the kid just be
51
places where foreign body often lodges; when is it clear to go
circopharyngeal narrowing, tracheal bifurcation, aortic notch, LES *clear once passes pylorus
52
when to consult for foreign body aspiration
sharp/elongated objects, multiple foreign bodies, button batteries, evidence of perforation, coin at cricopharyngeus muscle level, if present more than 24 hr
53
button battery in esophagus.. what is the worry?
alkaline battery on mucosa, pressure necrosis, residual charge; burns can occur in as little as 4 hours, perforation in 6, lithium is worst, mercuric oxide worry about fragmenting - measure blood and urine levels or contact national button battery ingestion hotline
54
tx button battery
emergent removal if in esophagus, if passed esophagus, no need to remove if asymp UNLESS doesn't move through pylorus after 24-48 hr if any GI sx, immediate surgical consult
55
near drowning outcomes
survival > 24 post event, but severe brain damage in 10-30% victims if come to ED comatose, needing CPR, fixed and dilated pupils, no resp = poor prog (30-60% die, 60-100% neuro complication)
56
when to worry about child abuse and drowning
if less than 6 mth or in toddlers with atypical presentation | *fences could prevent most drowning events
57
dry drowning
laryngospasm --> hypoxia --> LOC | *no fluid in lungs
58
wet drowning
more common, aspiration of water into lungs dilution and washout of surfactant --> diminished gas transfer across alveoli --> atelectasis --> ventilation perfusion mismatch - fresh vs salt water
59
secondary drowning - what is it and why is it dangerous
may cause death up to 72 hours after near drowning bc... | freshwater ingested during near drowning dilutes blood --> hemolysis and cardiac arrythmias if enough water ingested
60
tx drowning
pres hospital care is critical | in ED: ventilation, warmed isotonic IV fluids, address injuries, CXR and repeat at 6 hr, obs by neuro
61
Fever without a source
Rectal temp >38 deg c | goal is to identify occult infections: pneumonia, UTI, bacteremia/sepsis, herpes-virus, meningitis
62
how to manage fevers?
decide how to manage based on age and risk factors, appearance <2 mth is neonate, 2 mth-3 yr is infant/young children risk: birth hx, travel, exposures, vaccination, immune def
63
2 mth to 3 yr: non toxic management
UA cath, rapid viral testing (flu, RSV), stool for WBC and guaiac if diarrhea *if all these things are negative and they appear okay, are fully immunized, etc you can send them home --> f/u 24 hr with PCP
64
2 mth to 3 year: toxic management (judge based on appearance)
CBC with diff, CXR, UA cath, CSF analysis via lumbar puncture, stool for WBC and guaiac, rapid virus testing *admit for obs and begin empiric antibiotics while waiting for culture results
65
toxic management for infants less than 2 mth temp > 38 deg C
workup regardless of appearance; get pretinent birth hx (premature, STD exposure, PROM, fetal hypoxia, in NICU at all?)
66
neonatal fever: sx of infection, management
irritability * be careful with this documentation management: full septic workup, early administration of empiric antibiotics (cefotaxime, ampicillin) till culture results
67
febrile seizures age range and types
6mth to 5 yr simple febrile: less than 15 min, isolated complex febrile: > 15 min multiple in rapid succession usually benign unless prolonged aspiration, compromised ventilation/perfusion
