What is the maximum adult dose of succinylcholine?

The maximum adult dose of succinylcholine is recognized to be 150 mg for a single administration in emergency situations. Succinylcholine, a depolarizing neuromuscular blocker, is commonly used to facilitate intubation by causing rapid muscle paralysis. This maximum dose is determined by safety and efficacy considerations, as doses higher than this can lead to increased risk of complications such as prolonged neuromuscular blockade or adverse cardiovascular effects.

Understanding the pharmacodynamics and pharmacokinetics of succinylcholine allows medical professionals to effectively utilize this medication while minimizing risks. In patients with specific contraindications or risk factors—such as a history of malignant hyperthermia, electrolyte abnormalities, or certain neuromuscular diseases—care must be taken to not approach the upper limits of dosing.

Being aware of proper dosages ensures that healthcare providers can perform critical interventions safely and effectively, reinforcing the importance of adhering to established guidelines when administering medications in an emergency context.
