Influence of low-dose ropivacaine combined with sufentanil continuous epidural anesthesia on the analgesic effect of parturients undergoing painless delivery and maternal and infant outcomes
Objective To explore the influence of low-dose ropivacaine combined with sufentanil continuous epidural anesthesia on the analgesic effect of parturients undergoing painless delivery and maternal and infant outcomes.Methods A total of 100 parturients who were included in obstetric examination and planned to have painless delivery were divided into a control group(ropivacaine continuous epidural anesthesia)and an observation group(low-dose ropivacaine combined with sufentanil continuous epidural anesthesia)according to random number table method after being sequenced,with 50 cases in each group.Comparison was made on anesthetic and analgesic effect(onset time of anesthesia,complete block time,analgesic duration),stage of labor(first stage,second stage,third stage and total stage of labor),pain scores at different time periods(before analgesia,15 min after analgesia,30 min after analgesia,when the cervix was fully dilated)and maternal and infant outcomes between the two groups.Results The observation group had onset time of analgesia of(4.56±1.68)min and complete block time of(12.35±2.42)min,which were significantly shorter than(15.14±1.87)and(23.41±2.13)min in the control group;the observation group had longer analgesic duration of(5.38±0.57)h than(2.66±0.33)h in the control group;there was statistical significance(P<0.05).The observation group had duration of the first stage of labor of(376.22±61.23)min and the total duration of labor of(427.71±82.21)min,which were significantly shorter than(432.42±88.21)and(484.77±112.42)min in the control group,and there was statistical significance(P<0.05).There was no statistical significance in the duration of the second and third stages of labor between the two groups(P>0.05).In the observation group,the pain scores 15 min after analgesia,30 min after analgesia and when the cervix was fully dilated were(1.78±0.34),(1.23±0.24)and(1.54±0.28)points,which were significantly lower than(2.12±0.41),(1.87±0.27)and(3.23±1.16)points in the control group.There was statistical significance(P<0.05).There was no significant difference in Apgar score 10 min after birth and the incidence of nausea,vomiting,headache and urinary retention between the two groups(P>0.05).Conclusion The analgesic effect of low-dose ropivacaine combined with sufentanil continuous epidural anesthesia in painless delivery is significant,and it will not increase the adverse risk of maternal and infant outcomes.
