Abstract：Objective: To explore the application of ropivacaine intraspinal anesthesia combined with sufentanil in labor analgesia of primipara. Methods: 100 cases of primipara who delivered in our hospital were selected as the research object. The selected time range was from December 2016 to July 2018. They were divided into control group or compound group, 50 cases of primipara in each group. The control group was given ropivacaine intraspinal anesthesia, and the compound group was given ropivacaine intraspinal anesthesia combined with sufentanil. Anesthesia index, duration of labor, visual analogue scale (VAS) scores of 5, 30, 60 and 90 minutes before and after anesthesia, delivery mode and incidence of adverse reactions were compared between the two groups. Results: The onset time of analgesia (7.13±1.97) min, complete block time (12.59±2.34) min and duration of analgesia (153.43±26.57) min in the compound group were significantly shorter than those in the control group (16.45±2.14) min, 24.56±2.81) min and (106.35±31.27) min respectively The time of the third stage of labor (6.71±1.47) min was shorter than that of the control group (532.26±207.34) min, (46.86±10.47) min, (10.13±2.69) min; after anesthesia, the pain of the two groups of parturients was more relieved, but the pain degree of the compound group of parturients was (3.68±0.41), (2.56±0.33), (1.64±0.22), (1.57±0.21) respectively. It was significantly lower than that of the control group (4.76±0.49), (3.14±0.32), (2.58±0.24), (2.46±0.23); the natural delivery rate of 86.00% in the compond group was significantly higher than that of 62.00% in the control group (P<0.05). There was no significant difference in the incidence of adverse reactions between the two groups (P>0.05). Conclusion: The effect of ropivacaine combined with sufentanil on labor analgesia of primipara is better. It can take effect quickly, shorten the time of complete block, prolong the duration of analgesia, shorten the time of the first labor process, the second labor process and the third labor process, reduce the degree of pain of primipara and improve the rate of normal labor.
