The clinical effect of sufentanil combined with ropivacaine epidural anesthesia in emergency caesarean section

Objective: To investigate the effects and adverse reactions of different dosage of sufentanil combined with ropivacaine epidural anesthesia in caesarean section.Methods: One hundred and twenty puerperas were randomly divided into 3 groups(A,B and C group,40 cases in each group).Group A,B and C were treated with 0.5% ropivacaine for 15 ml combined with 10μg sufentanil for 1 ml,0.5% ropivacaine for 15 ml combined with 15μg sufentanil for 1 ml and 0.5% ropivacaine for 15 ml combined with 0.9% sodium chloride injection for 1 ml,respectively.The fetal Apgar score after delivery,onset of action,painless plane,improved Bromage score,visual analogue scale(VAS) and adverse reactions in three groups were observed.Results: Compared with the group C,the onset of action,painless plane time and the highest plane time in group A and B were significantly shortened(P<0.01),the duration of analgesia in group A and B was significantly prolonged(P<0.01).The differences of VAS score between three groups at cutting skin were not statistically significant(P>0.05).The differences of VAS score at exploration and delivery and incidence of shiver between three groups were statistically significant(P<0.01).The differences of the incidence of intraoperative hypotension,bradycardia,nausea,vomiting and itching between three groups were not statistically significant(P>0.05),the difference of Apgar score after delivery of the fetus was not statistically significant(P>0.05).Conclusions: The application of ropivacaine combined with sufentanil in caesarean section under epidural block can significantly enhance the effect of anesthesia,and relieve viscera retracting discomfortable symptoms and reduce the incidence of shiver.
