Which statement best describes the reason succinylcholine is preferred for intubation?

• A. It is long acting
• B. It is non-depolarizing
• C. It increases secretions
• D. Short acting and short to wear off

Answer: (D)

The main idea is achieving rapid airway control with paralysis that wears off quickly so the patient can resume breathing soon after the tube is placed. Succinylcholine is a depolarizing neuromuscular blocker that provides very fast onset, usually within seconds to a minute, and a short duration because it is rapidly broken down by plasma cholinesterase. This quick window allows intubation to be performed efficiently and, if needed, for spontaneous breathing to return quickly if intubation is straightforward or if ventilation becomes possible again. In contrast, long-acting or non-depolarizing agents have slower onset and linger longer, making them less ideal for intubation where temporary paralysis is desired. While succinylcholine can cause increased secretions and other risks, its defining advantage for intubation is its short acting nature and quick wear-off, which is why the best description is that it is short acting and short to wear off.
