Question

John J is a 32 year-old man about to undergo surgery to remove his inflammed appendix. John has a family history of malignant hyperthermia, as well as a genetic disorder causing resulting in very low atypical pseudocholinesterase activity. Based upon his medical history, John's surgeon uses caution when selecting both the type of general anesthetic and skeletal muscle relaxant prior to starting the procedure. What skeletal muscle relaxant should John's surgeon avoid using?

A. Atracurium
B. Pancuronium
C. Rocuronium
D. Succinylcholine
E. Vecuronium

Answer 1

John's surgeon should avoid using the skeletal muscle relaxant Succinylcholine.

Step-by-step explanation:

Based on John's medical history of having a family history of malignant hyperthermia and a genetic disorder causing low atypical pseudocholinesterase activity, his surgeon should avoid using the skeletal muscle relaxant Succinylcholine. Succinylcholine is contraindicated in patients with these conditions because it can trigger malignant hyperthermia and cause severe adverse reactions due to the low pseudocholinesterase activity.
