Abstract To explore the effect of dural puncture epidural block (DPEB) used in labor analgesia of primipara, and to study its influence on mother and infant. Methods: 100 primipara were selected and were divided into group A and group B (50 cases in each group) according to different analgesia methods from February 2020 to December 2020. The primipara in group A were given DPEB for labor analgesia, while the primipara in group B were given programmed intermittent epidural bolus (PIEB) and DPEB for labor analgesia. The visual analogue scale (VAS) score, the neonatal Apgar score, the delivery situation, the anesthetic dosage, the anesthetic effect, the adverse reactions rate, the satisfaction degree of the primipara, and the results of the umbilical cord arterial blood gas analysis were compared between the two groups. Results: The VAS scores of the primipara in group A at each time point of uterine contraction and after analgesia were significantly lower than those of the primipara in group B (P<0.05). There were no significant differences in Apgar score, the midwifery rate, the postpartum blood loss, the rate of oxytocin used, and the incidence of adverse reactions of the primipara between the two groups (P>0.05). The sufentanil and ropivacaine dosage, and PCA pressing frequency of the primipara in group A were significantly lower than those of the primipara in group B, and the sacral sensory block effect of the primipara in group A was significantly more extensive than that of the primipara in group B (P<0.05). There was no significant difference in the level of thoracic sensory block of the primipara between the two groups (P>0.05). The degree of anesthesia satisfaction (9.8±2.0 points) of the primipara in group A was significantly higher than that (8.1±1.8 points) of the primipara in group B (P<0.05). There were no significant differences in the results of the mbilical cord arterial blood gas analysis of the primipara between the two groups (P>0.05). Conclusion: DPEB used for primipara has good labor analgesic effect, which can reduce the dosage of anaesthetic drugs, improve satisfaction of primipara without adverse maternal and infant outcomes.
