What is the duration of action for succinylcholine?

The duration of action for succinylcholine is typically around 4 to 6 minutes. This neuromuscular blocker is commonly used for rapid sequence intubation because of its quick onset and relatively short duration. The reason it acts for this length of time is due to its rapid breakdown by plasma cholinesterase, which renders it non-active shortly after administration. This makes it especially useful in emergency settings where quick intubation is necessary, allowing patients to regain muscle function soon after the procedure. The pharmacodynamics of succinylcholine support its use in critical situations, balancing the need for immediate paralysis with the necessity for a swift return to normal respiratory function. Other options fall outside the typical duration, making them less accurate in describing succinylcholine's pharmacokinetics.
