Intravenous injection of flurbiprofen axetil and sufentanil combined with epidural morphine for post-cesarean analgesia

Abstract

Objective To investigate the analgesic effect and the safety assessment of intravenous injection of flurbiprofen axetil and sufentanil combined with epidural morphine for post-cesarean analgesia.Methods One hundred and eighty parturients (ASA Ⅰ-Ⅱ) undergoing elective cesarean section with combined spinal and epidural anesthesia were divided into morphine group (group A),sufentanil + morphine group(group B),flurbiprofen axetil+sufentanil+ morphine group(group C) with 60 cases in each group.All patients were used subarachnoid epidural anesthesia,at the end of the surgery,1.5 mg morphine diluted to 5 ml saline was injected into the epidural space of each patient.Additional,group B and group C received patient-controlled intravenous analgesia after cesarean section.Flurbiprofen axetil and sufentanil were diluted to 100 ml with saline.The visual analog scale (VAS) of rest and dynamic incisional pain and uterine contraction pain,Ramsay sedation scale (RSS),and adverse events were recorded at 6,12,24 h after operation.Results At 6,12,24 h after operation,the VAS scores of rest and dynamic incisional pain and uterine contraction pain in group B and group C were statistically lower than those in group A [rest incisional pain:(2.6 ± 0.6),(2.7 ± 0.4),(2.8 ± 0.3)scores in group A; (2.3 ± 0.3),(2.3 ± 0.4),(2.2 ± 0.3) scores in group B; (1.8 ± 0.4),(1.7 ±0.5),(1.9 ±0.4) scores in group C; dynamic incisional pain:(5.7 ±0.9),(5.5 ± 0.8),(5.6 ± 1.0) scores in group A; (3.8 ± 0.4),(3.7 ± 0.5),(3.7 ± 0.4) scores in group B ; (2.7 ± 0.4),(2.4 ± 0.5),(2.4 ± 0.6) scores in group C ; uterine contraction pain:(5.7 ± 1.2),(5.9 ± 0.9),(5.8 ± 1.1) scores in group A; (3.0 ± 0.5),(3.1 ± 0.6),(3.2 ± 0.7)scores in group B; (2.5 ± 0.5),(2.5 ± 0.6),(2.4 ± 0.4) scores in group C],and group C were lower than group B,and there were significant differences (P＜0.05).At 6,12,24 h after operation,Ramsay score in group B and group C was higher than that in group A [(1.8 ± 0.5),(1.7 ± 0.4),(1.9 ± 0.5) scores in group A; (3.4 ± 0.8),(3.2 ± 0.7),(3.3 ± 0.6) scores in group B; (2.7 ±0.7),(2.7 ±0.5),(2.6 ± 0.4)scores in group C],and group C was higher than group B,and there were significant differences (P ＜ 0.05).The incidence of adverse events in group A and group C was lower than group B [8.3％(5/60) and 23.3％(14/60) vs.40.0％(24/60)],and group A was lower than group C,and there were significant differences (P ＜ 0.05).Condusion Intravenous injection of flurbiprofen axetil and sufentanil combined with epidural morphine could perform better analgesic on postoperative incisional and uterine contraction pain after cesarean section and the incidence of adverse events is less than sufentanil combined with morphine.
