156
Consideration for managing pediatric peri-intubation hypotension
Give fluid bolus before induction (almost always helpful, especially if tubing for resp failure or sepsis)
Consider push dose pressors if severely hypotensive. Would personally be hesitant for push dose in kids, could consider epi or norepinephrine infusion if anticipating hypotension

mgmt of epiglottis
minimal intervention. do not try and visualize the throat unless can be done without agiatation/tongue blade etc
arrange for airway in OR with double setup, unless necessary loss of airway, can try BVM first then, tracheal intubation or FONA prn. be prepped for airwya while awaiting OR
only get IV if needed for airway mgmt unless pt is ++ chill
in terms of other mgmt: IV abx/fluids only if IV access can be secured without too much irritation/agitation as this will make hasten airway loss
keep them with parent, try some blow o2 etc.
