Is succinylcholine appropriate or obsolete in the intensive care unit?

Published by National Institutes of Health | U.S. Department of Health & Human Services | Metadata Last Checked: September 07, 2025 | Last Modified: 2025-09-06
Muscle relaxants in intensive care unit (ICU) patients are predominantly administered to facilitate intubation. The adverse effect profile of succinylcholine is such that its use in the ICU must be considered obsolete. Suitable alternatives are the intermediately long-acting nondepolarizing relaxants, of which rocuronium is probably preferable.
