TRUE statement regarding use of adrenaline in anaphylactic shock is:
Ans. (A) The usual dose is 0.5-1 mg by IM route(Ref: KDT 8th/e p150)Adrenaline 0.5 ml of 1 :1000 solution (i.e., 0.5 mg) by i.m. route is drug of choice for anaphylactic shock. It can also be used by s.c. routeIf not responding, it can be repeated after 5 minutes (not 2-4 hours). In desperate circumstances i.v. route can be used but it must be diluted 10 times (i.e., 1 : 10000 concentration is used), therefore same solution cannot be utilized, However, in rare circumstances, i.v. adrenaline can result in cerebral hemorrhage due to uncontrolled rise in blood pressure.
The usual dose is 0.5-1 mg by IM route
Cerebral hemorrhage never occurs as an adverse effect to epinephrine when used in treatment of anaphylactic shock
It is repeated after every 2-4 hours
Same solution can be given for SC as well as IV route
