Abstract:
Objective To evaluate the efficacy of continuous incision analgesia with 0.2％ levobupivacaine for postoperative analgesia in parturients undergoing cesarean section.Methods Thirty ASA physical status Ⅰ or Ⅱ parturients who were at full term,aged 20-30 yr,weighing 60-80 kg,undergoing elective cesarean section,were enrolled in the study.The parturients received 0.2％ levobupivacaine 2 ml/h via a continuous incision analgesia device at the end of surgery.Pain was evaluated by visual analogue scale (VAS).Additional tramadol 50 mg was given when VAS score was above 3 and the consumption was recorded.The effective analgesia within 48 h after surgery (no addition of tramadol,VAS score ≤3) was recorded.The serum prolactin level was measured at 30 min before cesarean section and 24 and 48 h after cesarean section.The colostrum time was recorded.The toxic reaction and side effects were recorded.Results The effective analgesia rate was 80 ％.The consumption of tramadol was (95 ± 15) mg.The colostrum time was (24 ± 6) h.No toxic reaction was found.The serum prolactin level was significantly higher at 24 and 48 h after surgery than that at 30 min before surgery (P ＜ 0.05).Conclusion Continuous incision analgesia with 0.2％ levobupivacaine provides better efficacy,earlier colostrum time and fewer side effects for postoperative analgesia in parturients undergoing cesarean section.
