目的观察硬膜外双管阻滞法用于分娩镇痛的临床效果及不良反应。方法选择100例自愿行分娩镇痛的产妇,随机分成两组,每组各50例,Ⅰ组采用双管阻滞法,选择腰1～2向上、腰3～4向下置管,Ⅱ组采用单管阻滞法选择腰2～3向上置管。两组用药均为0.1%～0.15%罗哌卡因+2μg/mL芬太尼。观察镇痛效果、不良反应、产程时间。结果Ⅰ组镇痛效果优良率84%,Ⅱ组优良率52%,两组比较Ⅰ组镇痛效果明显优于Ⅱ组(P<0.05);对产程的影响两组无统计学意义(P>0.05)。结论双管阻滞法较单管阻滞法有明显优势,镇痛效果更好、用药量少、可控性更强,值得临床推广应用。
Objective To observe the clinical effects and adverse reactions of epidural blockade on labor analgesia. Methods A total of 100 cases of labor analgesia were randomly divided into two groups (50 cases in each group). In group Ⅰ, double-block method was used. Single-block method using the waist 2 to 3 up tube. Both groups were given 0.1% ~ 0.15% ropivacaine plus 2μg / mL fentanyl. Analgesic effect, adverse reactions, labor time. Results The analgesic effect in group Ⅰ was 84%, the excellent and good rate in group Ⅱ was 52%. The analgesic effect of group Ⅰ was better than that of group Ⅱ (P <0.05). The effect on labor was no significant difference between the two groups (P> 0.05). Conclusion Double-tube blockade has obvious advantages over single-tube blockade, with better analgesic effect, less dosage and more controllability. It is worthy of clinical application.
