SUX stands for which term?

• A. Succinylcholine
• B. Sulfanyl Chloride
• C. Sulfurex
• D. Sulfursal Xylitol

Answer: (A)

SUX is the shorthand clinicians use for succinylcholine, a depolarizing neuromuscular blocker used to rapidly paralyze a patient for airway management such as rapid sequence intubation. The abbreviation comes from the sound of the first syllable of succinylcholine, a long-standing EMS shorthand. Succinylcholine works by binding to nicotinic acetylcholine receptors at the neuromuscular junction, causing a brief, sustained depolarization that prevents further signals and results in temporary paralysis. It has a very fast onset—typically 30 to 60 seconds—and a short duration, about 5 to 10 minutes, which is often ideal for securing the airway and then allowing the patient to recover muscle function. The other terms listed aren’t recognized abbreviations for this medication in routine practice; they’re not standard names for a clinically used drug in acute care.
