Ketamine may do which of the following in a patient with shock:
A) Raise blood pressure
B) Decrease blood pressure
C) Not cause a change in blood pressure
D) All of the above
There are some misconceptions about ketamine in emergency medicine and specifically in EMS. Some EMS providers believe ketamine will ALWAYS raise blood pressure, acting like a vasopressor. Ketamine is a great drug but in some patients it can decrease perfusion.
