Patients with butyrylcholinesterase (BChE) deficiency can experience prolonged paralysis after receiving suxamethonium or mivacurium. We hypothesized that patients suspected of BChE deficiency had a higher risk of being awakened while paralysed and having respiratory complications if neuromuscular monitoring was not applied before awakening. ⋯ Patients with BChE deficiency are at higher risk of being awakened while paralysed if neuromuscular monitoring is not applied or used; neuromuscular monitoring is recommended whenever a neuromuscular blocking agent is administered.
