RESUMO
ObjectiveTo investigate the effects of induction with Dezocine to prevent the agitation of the patient after remifentanil anesthesia.Methods60 patients of upper abdominal surgery,ASA Ⅰ ~ Ⅱ class,were randomly divided into 3 groups,20 patients in each group,anesthesia was induced with the midazolam 0.05 mg/kg,propofol 1 ~2mg/kg,vecuronium 0.12mg/kg.Analgesic drugs were administer as follow:control group,remifentanil ( group Rmf )1 μg/kg; fentanyl group ( group F) 4 μg/kg; Dezocine group ( group D) 0.2mg/kg.Remifentanil、propofol are used to maintain anesthesia.The time of recovery and extubation,the VAS pain score,the Ramsay score and adverse reactions such as vomiting,respiratory depression after extubation were recorded.ResultsCompared with group Rmf,the hemodynamic parameters was more stable in group F and group D.Compared with group F ( 1 μg/kg),the VAS pain score,the Ramsay score and adverse reactions significantly decreased in group D ( P < 0.05 ),and the time of extubation in group F was longer than group D(P < 0.05).Conclusion0.2mg/kg of Dezocine could be used for the induction of anesthesia to reduce the incidence of agitation and adverse reactions during recovery period.
