I was wondering what you all use for your upper limit of Diprivan for sedation? At work the other day had an issue where the patient was just not being sedated yet MDs did not want to change to another gtt. (He was s/p MVA with high ethanol level and drinker....duh...of course it isnt working....but I am just a nurse) Anyhow, drug insert is no help, called pharmacy they said they weren't sure either...isn't that your job? Anyhow, one insert said that 50 mcg/kg/min is high dose but that some have needed higher, no guidelines though. What is the highest you have seen on a vented pt with stable BP? (for sedation not in or....i was talking to CRNA after this and she said they go up to like 150 mcg in OR)
