In the NEALSIVMAN mapping, which drug corresponds to the letter S?

• A. Succinylcholine
• B. Lidocaine
• C. Versed
• D. Fentanyl

Answer: (A)

In NEALSIVMAN mapping, each letter points to a specific anesthetic drug, with S representing Succinylcholine. Succinylcholine is the depolarizing neuromuscular blocker chosen for rapid sequence induction because it has an ultrafast onset (about 30–60 seconds) and a very short duration (roughly 5–10 minutes). This quick, brief action is what the mnemonic key uses for the S slot. The other drugs listed—lidocaine, Versed, fentanyl—fit different letters in the mnemonic and have different primary roles, so they don’t occupy the S position.
