RESUMEN
Objective To observe the effect of mivacurium,succinylcholine and atracurium in modified electric convulsive therapy (MECT).Methods Sixty ASA Ⅰ or Ⅱ patients with schizo-phrenia aged from 18 to 60 years old were randomly divided into 3 groups :mivacurium group (group A,n=20),succinylcholine group (group B,n=20),atracurium group (group C,n=20).The on-set time of muscle relaxation,the recovery time of spontaneous breathing after MECT,the awake time,as well as the changes of 5 min MAP,HR and SpO2 before and after MECT were observed re-spectively.Results The onset time of muscle relaxation and the recovery time of spontaneous breath-ing in group B were shorter than those in groups A and C (P <0.05).The onset time of muscle re-laxation and the recovery time of spontaneous breathing in group A were shorter than those in group C (P <0.05).Conclusion Mivacurium is a better alternative medicine in MECT in the situation of no succinylcholine or succnylcholine contraindication.
