Abstract:Objective: To investigate the application of sufentanil and ropivacaine in postoperative analgesia for cesarean section and neonatal conditions. Methods: 200 cases of cesarean section delivery of singletons full-term birth admitted nearly 1 year in our hospital were randomly divided into two groups, respectively selected sufentanil combined with ropivacaine, epidural analgesia and pethidine intermittent intramuscular injection were used to relieve pain. Results: The visual analogue pain score of VAS in the observation group was significantly lower than that in the control group (P < 0.05), and the level of plasma prolactin after operation was obviously increased due to the control group (P < 0.05). The colostrum time of the observation group was significantly shorter than that of the control group (P < 0.05), and the number of breast feeding was significantly higher than that of the control group (P < 0.05). Conclusion: Sufentanil combined with ropivacaine epidural analgesia can effectively relieve the pain after cesarean section, improve prolactin levels in maternal blood, improve breast milk status, and have no adverse effects on the newborn.
