Use of atracurium in a patient with plasma cholinesterase deficiency.
The use of atracurium during anaesthesia for abdominal hysterectomy in a 37-year-old patient with homozygous plasma cholinesterase [EsEs] deficiency is described. Intubation was achieved utilizing 0.47 mg X kg-1 of atracurium. Subsequent doses of 0.08 mg X kg-1, 0.12 mg X kg-1 and 0.12 mg X kg-1 were given 34, 57 and 78 minutes respectively after the initial dose. At the time of reversal of the residual effects of neuromuscular blockade, 26 minutes after the last dose, spontaneous respiration had resumed. The duration of action of the drug was not different from that described in normal patients. Atracurium would appear to be a safe drug to provide neuromuscular relaxation in patients with plasma cholinesterase deficiency, where surgical procedures of intermediate duration are being undertaken.
