What is the typical dose of succinylcholine?

The typical dose of succinylcholine for adults is generally in the range of 1 to 2 mg/kg when administered intravenously, with the most commonly used dosages being around 1.5 to 2 mg/kg for rapid sequence induction during anesthesia. This dose range is particularly effective for inducing muscle relaxation quickly for procedures requiring intubation. Dosing at this level allows for rapid onset of action, typically within 30 to 60 seconds, which is ideal for emergency situations or where quick paralysis is required.

Higher doses, such as 3 to 4 mg/kg, are usually not recommended due to the increased risk of side effects and prolonged neuromuscular blockade. Lower doses, such as 1 mg/kg, may not provide the rapid onset or sufficient effect needed for certain surgical procedures. Therefore, the choice of 2 mg/kg strikes a balance between efficacy and safety, making it the standard for use in clinical settings.
