Abstract:

Background/aim: Knowledge regarding pain relief during labor remains insufficient. We aimed to determine and compare the effectiveness and safety of epidural analgesia, combined spinal-epidural analgesia, and parenteral meperidine on both mothers and fetuses. Materials and methods: This study was designed as an observational case-control study. We collected prospective data from patients whose labor pain management was conducted with meperidine in addition to retrospective cohort data of neuraxial methods; 138 patients were enrolled. Epidural analgesia group consisted of 68 patients, whereas combined spinal-epidural (CSE) analgesia group and meperidine group consisted of 50 and 20 patients, respectively. We compared the delivery patterns, labor durations, pain levels, side effects, maternal satisfaction levels, and neonatal outcomes of the various pain management methods. Results: Patient demographics, duration of first, second, and third labor stages, and instrumental delivery rates were comparable among groups (P > 0.05). Cesarean section tended to be less frequent in the CSE group. In the meperidine group, visual analog scale (VAS) values and sedation were significantly higher (P < 0.001) and maternal satisfaction lower (P < 0.001). Hypotension tended to be more frequent in the meperidine group. APGAR scores at the 1st and 5th min were similar among the groups and between meperidine subgroups defined by three different administration times ( 0.05). Conclusion: Neuraxial methods had no effect on instrumental delivery rates. CSE represented a near significant risk reduction in cesarean section. Our results demonstrated that regional analgesia methods were reasonably safe for both mother and fetus, and regional analgesia methods resulted in greater maternal satisfaction and pain control compared to meperidine.
