Commentary 6.1.4.


by Tomas Beran

Skeletal muscle relaxants are used in patients with severe traumatic brain injury to avoid excessive motor activity that increases ICP. Patients must have continuous ICP monitoring. The recommended relaxants are succinylcholine, atracurium, vecuronium and pancuronium1-4.

After 72 hrs, it is preferable to induce analgesia and sedation. If skeletal muscle paralysis is necessary, atracurium, vecuronium or pancuronium are recommended 5-7.
