Clinical research of epidural ropivacaine infusion combined with fentanyl or tramadol for postoperative analgesia

Objective To observe the effect of fentanyl and tramadol in combination with ropivacaine on continuous epidural postoperative analgesia.Methods Sixty patients,undergoing uterine-incision delivery,were randomly divided into three groups(20 in each group) to receive 0.2% ropivacaine alone(Group R),0.2% ropivacaine plus 0.0004% fentanyl(Group F),and 0.2% ropivacaine plus 0.5% tramadol(Group T).The disposable micro-infusion pump was applied to continuous epidural postoperative analgesia.VAS were recorded at different time.The incidence of side-effect was assessed.Results The VAS in Group F or Group T were significantly less than that in Group R(P0.05)and no significant difference were noted between Group F and Group T(P0.05).The incidence of nausea and vomiting in Group T was significantly lower than that in Group F(P0.05).Conclusions Ropivacaine infusion combined with tramadol is the better choice because of the less side-effects.
