2. Peds/Neonates Flashcards
narrowest part of airway
cricoid carilage
RR
increased
metabolic consumption
increased
6-8 mL/kg/min
lung compliance
reduced
chest wall compliance
increased
FRC
reduced
head/tongue
larger
nasal passages
narrower
larynx
anterior
cephalad
epiglottis
longer
trachea/neck
shorter
adenoids/tonsils
more prominent
intercostal/diaphragm muscles
weaker
resistance to airflow
greater
neonates and infants are obligate
nasal breathers
CV is dependednt on
HR
HR
increased
BP
reduced
LV
non-compliant
CV summary: peds
1) HR-dependent CO
2) incr HR
3) reduced BP
4) non-compliant LV
5) residual fetal circulation
6) potential difficult venous/arterial cannulation
BSA is _______
larger
how do neonates warm themselves?
brown fat metabolism for nonshivering thermogenesis
what inhibits brown fat metabolism
anesthesia
BSA calculation
BSA = sqrt[(height x weight)/3600]
when does peds renal function normalize
6 months
peds glycogen
reduced which can cause hypoglycemia
peds drug dosing should be
allometric
50th percentile for weight
(Age x 2) + 9
neonate TBW
more than that of an adult
incr TBW =
incr volume of distribution of drug
== higher dosing needed
which pt population has highest anesthetic requirement for inhalational?
3 month olds
fast emergence can cause
incr risk of post-op delerium
volatile agent impact on myocardium
sensitizes myocardium to catecholamines
propofol infusion syndrome SE
HD instabolity
brady
hTN
green urine
propofol infusion most common pt
critically ill children
opioids peds
more pronounced effect due to immature mu receptors
remi dosing for peds
need to increase dosing due to incr clearance
dexmedetomidine nasal sedation dose
1-2 mcg/kg
