ABSTRACT
Objective To investigate the clinical efficacy and side effects of nalbuphine for treatment of post combined spinal epidural anesthesia shivering undergoing cesarean section.Methods Ninety puerpera underwent elective caesarean section under combined spinal-epidural anesthesia,who developed shivering Wrench grade 3 or 4,aged 20-35 years,ASA physical status Ⅰ or Ⅱ,were randomly and double-blindly divided into three groups with 30 puerpera each to receive either saline (group C) or nalbuphine (group N,0.07 mg/kg) or tramadol (group T,1 mg/kg) as a slow intravenous bolus for treatment of shivering.Onset of shivering,time interval from treatment to cessation of shivering,success rate,recurrence rate after successon treatment outcome of shivering,OAA/S sedation scores,nausea and vomiting,bradycardia and hypotension were recorded.Results There was no significant difference of the time interval from treatment to cessation of shivering between the three groups.Compared with group C,there was statistically significant shorter time interval from treatment to cessation of shiveringin group N [(3.6±1.3) min vs (14.3±7.3) min] and group T [(4.2± 2.2) min vs (14.3±7.3) min],higher success ratein group N (93.3％ vs 16.7％) and group T (90％ vs 16.7％) and lower recurrance ratein group N (7.1％ vs 80.0％) and group T (11.1％ vs 80.0％)(P＜ 0.05).Higher sedation scores in group N were observed (P＜0.05).The incidence of nausea and vomiting was 60.0％ in group T,which was significantly higher than those in group C (20.0％) and group N (13.3％) (P＜0.05).There was no significant difference in the incidence of bradycardia and hypotension in three groups.Conclusion Nalbuphine can control the shivering of post combined spinal epidural anesthesia undergoing cesarean section safely and effectively,which seems suitable for parturients cesarean delivery due to the lower incidence of nause and vomiting and a certain sedation effect.
