Which medication should be avoided during induction in a patient with myotonic dystrophy?

• A. Propofol
• B. Succinylcholine
• C. Rocuronium
• D. Fentanyl

Answer: (B)

In patients with myotonic dystrophy, succinylcholine is the medication that should be avoided during induction due to the risk of inducing a prolonged myotonic reaction. Succinylcholine, a depolarizing muscle relaxant, can cause muscle contractions that are problematic for individuals with myotonic dystrophy. This disorder is characterized by muscle stiffness and delayed relaxation following contraction, which may be exacerbated by succinylcholine administration, leading to significant postoperative complications. The use of depolarizing agents like succinylcholine can trigger severe and prolonged muscle contractions or myotonia, which may complicate intubation and recovery. As a result, it is generally recommended to opt for non-depolarizing neuromuscular blockers in these patients, as they do not share the same mechanism of action and are associated with a lower risk of precipitating these neuromuscular complications. Other medications listed, such as propofol, rocuronium, and fentanyl, do not carry the same risks associated with myotonic dystrophy. Propofol is primarily an anesthetic agent, rocuronium is a non-depolarizing neuromuscular blocker, and fentanyl is an opioid analgesic. While they all
