不同剂量罗哌卡因腹横肌平面阻滞用于剖宫产术后镇痛的效果

Effect of Different Doses of Ropivacaine in Transversus Abdominis Plane Block After Cesarean Section Analgesia

目的探讨不同剂量罗哌卡因腹横肌平面阻滞用于剖宫产术后镇痛的效果。方法选取我院剖宫产产妇200例,随机分为观察组和对照组,每组患者均为100例,两组患者术后双侧腹横肌平面分别注射0.5%的罗哌卡因3.0 mg/kg、1.5 mg/kg,并使用PCIA。结果麻醉手术后,观察组的呼吸、血压、心率均低于对照组(P<0.05),与对照组比较,观察组产妇的术后不同时间VAS评分降低(P<0.05),观察组产妇对镇痛满意率增加,镇痛泵按压次数减少(P<0.05)。结论 0.5%罗哌卡因3.0 mg/kg剂量腹横肌平面阻滞联合PCIA用于剖宫产术后镇痛,安全有效,效果更好。

Objective To explore the effect of different doses ropivacaine in transversus abdominis plane block on post-cesarean analgesia. Methods Selected 200 parturients who underwent caesarean section from our hospital,randomly separated them into an observation group and a control group,each with 100 cases. 3.0 mg/kg and 1.5 mg/kg 0.5% ropivacaine were injected respectively on transversus abdominis planes of both sides after surgeries of the two groups,and then PCIA was used.Results After anesthesia operations,the respiration,blood pressure,and heart rate of the observation group al were lower than those of the control group （P〈0.05）,the VAS of the observation group parturients at different points of time after surgery were significantly lower（P〈0.05）,and the satisfaction rate of the observation group parturients was clearly higher,with the analgesia pump pressing much less frequent（P〈0.05）.Conclusion 3.0 mg/kg dose of 0.5% ropivacaine transversus abdominis plane block together with PCIA is safe,efficient and effective in postoperative analgesia of cesarean section.
