Abstract:
OBJECTIVE To investigate the effect of ropivacaine combined with dexmedetomidine on postoperative analgesia in women undergoing cesarean section， and to explore the feasibility of the opioid-free analgesia mode after cesarean section under spinal-epidural anesthesia. METHODS Totally 80 women undergoing cesarean section were randomly divided into observation group （ropivacaine combined with dexmedetomidine for analgesia） and control group （ropivacaine combined with opioid drug sufentanil for analgesia） ， with 40 cases in each group. The exercise and rest score in visual analogue scale （VAS） within 48 hours after operation， the use of analgesia pump （the time of first analgesia pump pressing， the times of analgesia pump pressing within 24 hours and 48 hours after operation）， the time of block （the onset time of spinal anesthesia sensory block， the time to the highest level of spinal anesthesia sensory block， the time of sensory recovery and the time of movement recovery） ， the time of prognosis （the time of gastrointestinal ventilation recovery， the time of getting out of bed and the hospitalization time）， and the incidence of adverse events were compared in 2 groups. RESULTS Finally， 64 parturients （32 in the observation group and 32 in the control group） were involved in the analysis. Compared with the control group， the recovery time of sensation and movement were significantly prolonged， the ventilation time was significantly shortened， and the incidence of nausea， vomiting and abdominal distension was significantly decreased in the observation group （P＜0.05） . There was no significant difference in the other indexes between the two groups （P＞0.05）. CONCLUSIONS Ropivacaine combined with dexmedetomidine under spinal-epidural anesthesia could provide similar analgesic effect as combined with opioids drug sufentanil， shorten the time of gastrointestinal ventilation recovery， and reduce the incidence of nausea，vomiting and abdominal distension， with no increased risk of low blood pressure or urinary retention.
