Comparison of the effects of butorphanol and tramadol on shiver in patients with cesarean section

Abstract

Objective To compare the effects of butorphanol and tramadol on shiver in patients with cesarean section.Methods 200 cases with maternal shiver (both for waist hard combined anesthesia,ASA Ⅰ ～ Ⅱ) were chosen in this study.According to the digital meter method,they were randomly divided into two groups,100 cases in each group.The observation group(group Ⅰ) was intraoperatively given butorphanol (0.015mg/kg),the control group(group Ⅱ) was intraoperatively given tramadol(1mg/kg).Shivers rating before and after drug use 5min,10min,adverse reactions,blood pressure (MAP),heart rate (HR),respiratory (RR),pulse oxygen saturation (SpO2)and incidence rate of adverse reaction were recorded.Results Perioperative and postoperative BP,HR,RR,SpO2,etc between two groups had no statistically significant differences (P ＞ 0.05).At 5 min,10 min,the total effective rate of shiver vanishing of the observation group was 100％ and 98％,respectively,which of the control group was 100％ and 88％,respectively,the differences between the two groups were not statistically significant (P ＞ 0.05).In the observation group,intraoperative blood pressure decline occurred in 5 cases,sleepiness 8 cases,nausea and vomiting 1 case,recurrence of shivers in 2 cases,those in control group were 4 cases,6 cases,26 cases,12 cases.Blood pressure drop and incidence rate of sleepiness between two groups had no statistically significant differences(P ＞ 0.05).Nausea and vomiting,the incidence rate of recurrent shiver between two groups had statistically significant differences (x2 =26.7609,7.6805,all P ＜ 0.05).Conclusion The effect of butorphanol is better than tramadol in treatment of cesarean section intraoperatie shivers.
