Succinylcholine
Succinylcholine is the fastest neuromuscular blocker (30–60s onset, 5–10min duration), ideal for RSI. Its dangers include life-threatening hyperkalemia in denervation/burns, malignant hyperthermia, bradycardia in children, and prolonged paralysis in pseudocholinesterase deficiency. Always scrutinize potassium and MH history before use.
