Abstract:
ObjectiveTo compare the effects of programmed intermittent epidural bolus （PIEB） and continuous epidural infusion （CEI） on enhanced recovery after cesarean section. MethodsTotally 120 women scheduled to undergo elective cesarean section under combined spinal and epidural anesthesia， aged 18-45 years， with single fetus， full-term pregnancy （≥37 weeks）， ASA grade II or III， were recruited， with 60 cases in each group. At the end of the surgery， after a similar epidural loading dose， patients were randomLy assigned to receive either PIEB （6 mL·h-1 beginning 30 minutes after the loading dose） or CEI （6 mL·h-1， beginning immediately after the loading dose） for the maintenance of analgesia with 0.1% ropivacaine. At 2， 6， 12， 24 and 36 h postoperatively， VAS score was used to evaluate the composite pain， and Bromage Score was used to evaluate the degree of lower extremity motor block. The time to first flatus， time to first ambulation and the satisfaction scores were also recorded. ResultsThe VAS scores at 12， 24 and 36 h postoperatively and the lower extremity motor block scores at 6， 12 and 24 h postoperatively in the PIEB group were significantly lower than those in the CEI group （P < 0.01）. The epidural analgesic dosage was less in the PIEB group than that of the CEI group （P=0.002）. The time to first flatus and time to first ambulation were significantly shorter than those in the CEI group （P < 0.05）. The satisfaction scores were significantly higher in the PIEB group than in the CEI group （P < 0.05）. There was no significant difference in the first urination time after urinary catheter removal and the length of hospital stay between the two groups （P > 0.05）. ConclusionCompared with CEI， PIEB provides better postoperative analgesia， less motor block scores， lower epidural analgesic dosage， shorter the time to first flatus and defecation and time to first ambulation， and greater patient satisfaction， which is more consistent with the ERAS concept of analgesia.
