pediatric a/w +trauma Flashcards
physiological differences of peds anatomy….
- larger head, larger tongue, higher larynx, flat/flexible epiglottis thats funnel shaped, vocal cords are lower and more forward, less residual long capacity
resistance to air flow formula?
=inversly proportionate to the 4th power of the radius of the airway
size of infant airway?
4mm across while adults are 8mm a
how should you lay your pediatric pt down?
rolled towel/blanket under the patient shoulders to align a/w! do not over extend neck, sniff position, chin life to move tongue out tf the way
what are common ages to have mechanical airway obstructions?
12-24 months
how to treat airway obtructions?
basic maneuvers, Back-blows/chest thrust?abdo thrusts, suction at (80mmhg-100mmhg)
child vsa
1 analysis than transport (unless vf-3 analysis then transport), 2 breaths- 15 compressions ( solo), check a/w after 1 round *noadjuncts for FBAO
what is CROUP?
Laryngotacheobronchiolitis
- subglottic airway infection usually affecting pt ages 3months-3 years old,Hx of URTI/fever/runny nose etc. causes major airway swelling, baring cough at night time, slow onset (24-72 hours), impending respiratory failure
management for croup?
blow by O2 w/ simple face mask, NRB if tolerated, neb EPI, dexamethasone, PPV prn, cold air
indications for nebulize epi?
current history of URTI
conditions for neb epi?
> 6 months-8 yrs old, hr=<200bpm, stridor at rest
Contraindications for epi?
allergy/sensitivity
croup standard tx?
weight=<10kg, route: NEB, concentration: 1:1000, dose=25mg, ma single=25mg, max #=1
Weight>10kg, dose=5mg, max single=5mg, max#=1
what is epiglotitis?
supraglottic viral infection with a rapid onset of high fever, drooling, SOB/stridor w/ retractions
epiglotitis management?
keep kid calm ( w parent), DO NOT INSPECT A/W, sniff possition, O2, ppv w/ BVM prn, support under the pt shoulders for alignment!
pediatric respiratory triangle
1)appearance: muscle tone, speech, retractions etc
2) circulation: pallor, cyanosis, mottling
3) WOB: abnormal?head bobbing?nasal flare?
what is the pediatric Tidal volume?
5-6mls/kg, vent till you see chest rise & fall
why is a scared child crying concerning?
+secretions, +aw irritability, +risk of laryngospasms, +a/w edema+wheeze
normal breathing rates for peds:
3months-6months: 25-45bpm
0-3months:30-60bpm
*higher metabolic demand
presentation of aspiration in peds?
dyspnea/tachypnea, fever, crackles, pleural rib, decreased breath sounds
Asthma:
chronic a/w inflammation and bronchial hyperactiviry causing bronchospasms and air trapping when exacerbated (ex exercise). will have dyspnea/tachypnea, tachycardia, chest tightness, pulsus paradoxus
triad for asthma:
dyspnea, wheeze, cough
what is pulsus paradoxus?
when you SBP changes by 10 sd during inspiration
Status asthmaticus:
caused by an acute exacerbation. pt is unresponsive to initial bronchodilators and will be hypercapnic–> resp fialure & retarctions&wheeze& pneumo, lethargy
- give pt epi first, then bag so air can get in
CF?
cyctic fibrosis genetic disorder characterized by abnormal Cl- ion transport on the surface of the epithelial cells in the exocrine glands causing sticky thick secretions of mucous that obstructs small bronchioles.
- airtrapping, electrolyte imbalances, digestive issues, salty skin on babies, dyspnea, chronic cough, sputum, fracturs
Bronchiolitis (febrile disorder)
inflammation of the small airways in the lower resp tract—> necrosis caused by RSV. common in ages 1-12 months, <2 yrs)
presentation: recent fever/cold, dyspnea, wheeze, crackles, chest retarctions
pneumonia
can be bacterial, virus, or fungal, commonly strep. Inflammation of the lung parenchyma–> aveolar exudate.
presentation: fever, dyspnea, sputum or not, pleuritic cp, unilateral crackles
