Q: Succinylcholine should be use with caution for intubation in all of the  following patients with except 

A) Neuromuscular diseases

B) Burns, 

C) Closed head injury,

 D) Drowning,

 E) Acute MI 

Answer: E

It is well known that Succinylcholine should be used with caution in some patients as a single injection of Succinylcholine can lead to massive release of potassium from skeletal muscles, like in patients with neuromuscular diseases (Guillain–Barré syndrome, myopathy, tetanus), burns, closed head injury, massive acidosis. Often forgotten and missed in this list is the near drowning patients.

Acute myocardial infarction (MI) is not a contra-indication to use of Succinylcholine.
