Which postoperative risk should be closely monitored after administration of succinylcholine?

• A. Potential malignant hyperthermia
• B. Hypotension
• C. Hypoglycemia
• D. Nausea

Answer: (A)

Succinylcholine can trigger malignant hyperthermia in susceptible individuals, so monitoring for this reaction after its administration is essential. Malignant hyperthermia is a dangerous, genetically mediated hypermetabolic crisis in skeletal muscle triggered by certain anesthetic agents, including succinylcholine. It causes rapid increases in carbon dioxide production, tachycardia, muscle rigidity, and, if unchecked, rising body temperature and metabolic acidosis. Signs can appear during surgery or in the early postoperative period, so vigilant monitoring of vital signs, end-tidal CO2, oxygenation, and muscle tone is crucial. Early detection and treatment with dantrolene, along with supportive care, are key to preventing severe complications. The other options are not as closely linked to succinylcholine and do not require the same level of immediate postoperative vigilance for this specific drug reaction.
