[外文]Objectives To evaluate the efficacy, safety and security of whole-range epidural analgesia for labor.
Methods Forty nulliparous primiparae without contraindication for epidural anesthesia were enrolled. Epidual analgesia was performed on demand after the emergence of regular uterine contraction, and the primiparae were divided into Group A or B according to the timing of analgesia initiation. Whole range analgesia was initiated instantly at the time of cervical dilatation = 1 cm in group A and conventional analgesia was administered when cervical dilatation ≥ 3 cm in Group B. Analgesia result, time length of labor, modes of delivery, neonatal blood gas analysis and weight, and neonatal Apgar score were recorded.
Results Cesarean section was needed in a total of 5 cases, and oxytocin dose was similar between the two groups. The two groups are not significantly different in time kength of labor stage II and III, modes of delivery, neonatal Apgar score, neonatal weight, umbilical venous blood gas analysis, neonatal outcome and postpartum hemorrhage (P > 0.00).
Conclusion Whole range epidural analgesia provides parturients with favorable intra-partum and post-partum analgesia without delay of labor stage II and III, increase in postpartum hemorrhage and adverse effect on neonatal Apgar score.[/外文]
