Q

Differences in musculokseletal system in ped pts?

A
  • ped bone has higher water content and lower mineral content: so less brittle than adult bone, thick periosteum in kids, rich blood supply
  • physis (growth plate): cartilagionous structure that is weaker than bone predisposed to injury
20
Q

Most commonly fractured bone in kids?

A
  • clavicle
  • younger kids fracture upper extremities
  • get older, more risk for lower extremity fractures
  • closed reductions of fractures more common in kids
21
Q

Why are kids at risk for head trauma?

A
  • large heads
  • thin skulls
  • poor muscle control
  • diffuse edema more common than intracranial hematomas
22
Q

When should you consider the possibility of serious injury in a child?

A
  • if injured child has altered mental status or appears to have inappropriate behavior
  • sig mechanism regardless of whether there are obvious injuries
  • injured child has evidence of poor systemic perfusion
23
Q

Guidelines for neuroimaging in head trauma?

A
  • imaging recommended if LOC greater than 1 min, evidence of skull fx, or focal neuro findings
  • consider imaging or observation if brief LOC
24
Q

There is an increased likelihood of intracranial injury if what sxs and signs are present?

A
  • immediate seizures
  • HA
  • vomiting
  • lethargy
25
GCS of 13 or 14, what should be done?
- emergent neuro imaging
26
GCS of 15 with LOC or PTA, what should be done?
- warrants strong consideration for neuro-imaging
27
What are signs of elevated ICP?
- AVPU (alert, voice, pain, unresponsive) - pupils - vomiting - cushing response (HTN, bradycardia, apnea) - controlled hyperventilation if IICP - resuscitate hypovolemic shock aggressively
28
Concussion definition?
- in children generally defined as sx head injury with no intracranial injury identified with CT (mild TBI)
29
Presentation of a concussion?
- HA - confusion and disorientation - difficulties with memory - inattentiveness - dizziness
30
Management of a concussion?
- physical and cognitive rest primary interventions - assessment for concomitant injuries - may use meds for HA and nausea short term - gradual return to activity after sxs have resolved - return to play only after pt is asx and has progressed through increasing levels of exertion w/o sxs
31
Common causes of poisoning in peds?
- cosmetic and personal care products - cleaning substances - analgesics - plants - cough and cold meds risk of ingestion: -improper or dangerous storage practices (cupboard locks), changes in normal home routines, visiting grandma
32
Dangerous Rxs for kids?
- antidepressants (TCAs especially, not so much SSRIs) - sedatives and antipsychotics - stimulants and ilicit drugs - cardiac meds
33
Assessment of acetaminophen overdose?
- # tabs or syrup ingested? strength? - toxic exposure is suggested when greater than 140 mg/kg ingested in single dose when greater than 7.5 g is ingested within 24 hr period - serum acetaminophen levle: draw 4 hrs following ingestion in anyone suspected of overdose - toxicity nomogram to determine need for tx
34
APAP overdose presentation over time?
- variable and depends on length of time following ingestion - stage 1: first 24 hrs - often minimal signs and sxs of toxicity, perhaps anorexia, N/V, pallor, malaise - stage 2: 2-3 days - signs of hepatotoxicity including RUQ pain and tenderness, elevated LFTs nad bilirubin - stage 3: 3-4 days - some pts will progress to fulminant hepatic failure, findings: metabolic acidosis, coagulopathy, renal failure, encephalopathy, and recurrent GI sxs - stage 4: pts who survive stage 3
35
What is happening to body during Acetaminophen overdose?
- initially liver breaks it down to non-toxic form - shortly after however because of high acetaminophen load - glutathione levels are depleted - when glutathione stores decrease to less than 30% of nomral, hepatic necrosis ensues (if sufficient amt of acetaminophen remaining) - N-acetylcysteine (mucomyst) works to counteract hepatic toxicity by replenishing glutathione
36
Management of acetaminophen overdose?
- GI decontamination with early admin of activated charcoal orally or through NG tube - Mucomyst: 140 mg/kg then maintenance dose (70 mg/kg) q 4 hrx 17 doses - supportive care - no ipecac to induce vomitng - this will delay admin of mucomyst
37
Why has number of exposures to aspirin decreased?
- fear of Reyes - lower dose of chewable forms (81 mg) - restriction on number of tabs/bottle
38
Presentation of Aspirin overdose?
- typically: tinnitus and vomiting - hyperpnea, fever, lethargy, confusion, convulsions, coma, resp/cardiac failuire - sx onset within few hrs following ingestion - dx: plasma salicylate concentrations
39
Tx of aspirin overdose?
- no specific antidote - activated charcoal - alkalinization with IV bicarb - dialysis may be necessary
40
Iron is toxic to what body systems?
- GI, cardiovascular and CNS | - will cause metabolic acidosis
41
Presentation of iron overdose?
- initial GI sxs: vomiting, abdominal pain, GI bleed, diarrhea - stable period (after 6 hrs and up to 24 hrs sxs may resolve, which may falsely reassure you) - resolution of GI sxs is presumed to occur as circulatting free Fe is redistributed into reticuloendothelial systems - can progress to circulatory shock
42
Dx of Fe overdose?
- abdominal xray: can see pure Fe, but vitamins won't show up - serum Fe concentrations
43
Tx of Fe overdose?
- whole bowel irrigation - don't use ipecac, may obscure initial signs of clinical toxicity and it isn't thought to be more effective than gastric emptying than Fe-induced vomiting - activated charcoal not recommended, doesn't absorb sig amounts of Fe - blood levels to determine toxicity - deferoxamine IV (chelating agent) for severe cases
44
Amt of Fe ingestion and sxs?
- pts who ingest less than 20 mg/kg of elemental Fe are usually asx - 20-60 mg/kg may or may not produce sxs of serious toxicity - small # of pts who have taken 40-60 mg/kg of Fe are sx - ingestions of more than 60 mg/kg can be assoc with serious toxicity - death from Fe toxicity has been reported from wide range of doses (60-300 mg/kg)
45
Lead poisoning? Causes?
aka: plumbism - insidious disorder but may have acute episodes (repetitive ingestions of small amts far more serious and common than single massive exposure) - paint/paint chip ingestion - contaminated household dusts in old homes - living near lead smelter - lead contaminated soils
46
Presentation of lead poisoning? | Tx?
- vague sxs: weakness, irritability, wt loss, vomiting, personality changes, ataxia, constipation, HA, colicky abdominal pain, developmental delay, behavioral disorders, seizures, peripheral neuropathy - blood disorders: anemia - tx: interrupt ingestion chelation therapy with succimer (in sx children) - SCREEN appropriately!!
47
key intervention for APAP overdose? Why?
- N-acetlycystein (mucomyst), replenishes glutathione which reduces APAP to nontoxic form
