目的基于低浓度局麻药探讨两种不同椎管内阻滞在潜伏期分娩镇痛中的临床价值。方法将孕妇200例随机分为试验组和对照组,每组100例。2组患者均于潜伏期给予低浓度局麻药,试验组选择双管硬膜外阻滞分娩镇痛,对照组选择腰硬联合阻滞分娩镇痛,观察2组患者麻醉镇痛效果。结果试验组分娩后VAS评分、第一产程末血清皮质醇、剖宫产率、产后出血量及麻醉并发症发生率均低于对照组,自然分娩率和新生儿Apgar评分均高于对照组,差异均有统计学意义(P<0.05)。结论基于低浓度局麻药的双管硬膜外阻滞分娩镇痛较腰硬联合阻滞分娩镇痛具有更好的镇痛效果和妊娠结局。
Objective To investigate the clinical value of two different spinal blockades in labor analgesia of latent period based on low concentration of local anesthetics. Methods 200 pregnant women were randomly divided into experimental group and control group, 100 cases in each group. Two groups of patients were given low concentration of local anesthetic in the incubation period. The experimental group was given dual-tube epidural analgesia for labor and the control group was used for analgesia combined with delayed labor. The analgesic effects of anesthesia were observed in the two groups. Results The VAS score, the serum cortisol, cesarean section rate, postpartum hemorrhage volume and anesthesia complication rate in the experimental group after delivery were all lower than those in the control group. The rates of spontaneous delivery and neonatal Apgar scores were higher in the experimental group than those in the control group. The differences were statistically significant (P <0.05). Conclusion The double analgesia and labor-induced analgesia based on low-concentration local anesthetics have better analgesic effect and pregnancy outcome than combined spinal-epidural analgesia.
