Vecuronium, pancuronium, and cis-atracurium are other non-depolarizing agents that are not affected by this enzyme deficiency. Etomidate is used for rapid sequence induction and is not affected by pseudocholinesterase deficiency; etomidate does block steroid synthesis and has been associated with acute adrenal insufficiency', 'role': 'assistant'}]
