Comparison of the effects of dezocine and tramadol for the prevention of shivering in cesarean section

Objective To observe the effect and safety of dezocine and tramadol for the prevention of shivering in cesarean section. Methods According to the digital table,240 routine cesarean mothers(both epidural anesthesia, ASAⅠ-Ⅱ)were randomly divided into three groups, each group in 80 cases. After the completion of combined spinal epidural, group A received verdict preventive maternal supine dezocine intravenous 0.1mg/ kg(diluted to 20m L with saline), group B for prophylactic intravenous tramadol 1mg/kg(with saline diluted to 20m L),group C(control group)received normal saline 20m L,continuous monitoring of perioperative respiratory, circulation changes, maternal chills,adverse reactions and Apgar score were observed and recorded. Results The incidence of post-anesthetic shivering maternal of group A and group B were 5.0%,7.5%respectively, while the rate was 60%in group C,there was significant difference between group A and group B(H=3.418, P=0.019);,but the maternal nausea and vomiting incidence of group B(45.0%)was significantly higher than those of group A(10.0%)and group C(7.5%)(χ2=11.491,P=0.021).There were no statistically significant differences in neonatal Apgar score among three groups(F=10.062,P=0.017). Conclusion Tramadol and dezocine can effectively prevent shivering during cesarean section and had no effect on the Apgar score, but tramadol incidence of nausea and vomiting was significantly higher than that of Dezocine, which is recommended for clinical use to rank and file Sim prevent cesarean section shivering response.
