Aim To investigate perinatal outcomes, the analgesic efficacy and maternal satisfaction in nulliparous women receiving fentanyl intravenous patient‐controlled analgesia (i.v.‐ PCA ). Material and Methods A total of 1401 nulliparous women with a singleton pregnancy who received fentanyl i.v.‐ PCA (i.v.‐ PCA group, n = 290) or no analgesia (control group, n = 1111) in labor between 2005 and 2010 were reviewed. Fentanyl i.v.‐ PCA was implemented on maternal request during the first stage of labor over 35 weeks of gestation, and discontinued at full cervical dilatation. Perinatal outcomes were compared between the i.v.‐ PCA and the control groups. The numerical rating scale ( NRS ) levels during labor were also examined in the i.v.‐ PCA group. Additionally, parturients received fentanyl i.v.‐ PCA in 2010 ( n = 73) were asked about overall satisfaction using a scale poor, moderate, good and excellent on postpartum day 0–3. Results Women receiving i.v.‐ PCA showed significantly longer labor and more need of oxytocin augmentation, compared with the control. Cesarean section was significantly less frequent in the i.v.‐ PCA group compared with the control (11.0% v.s. 24.1%, respectively), with the vacuum‐assisted delivery rate comparable between groups. Neonatal outcomes (i.e. Apgar score <7 at 1 min or 5 min, umbilical artery pH <7.20) were comparable between groups, irrespective of mode of delivery. Significant reduction of NRS levels was noted until 3 h after induction of i.v.‐ PCA , compared to the baseline. Of the women who expressed their satisfaction, 72% (48/67) exhibited ‘excellent’ or ‘good’ for pain relief by i.v.‐ PCA . Conclusion Fentanyl i.v.‐ PCA could be a useful approach for labor pain relief in nulliparas when regional blocks are unavailable.
