腰硬联合麻醉对剖宫产产妇围术期凝血功能、RAAS活性及术后镇痛效果的影响

目的探讨腰硬联合麻醉对剖宫产产妇围术期凝血功能、RAAS活性及术后镇痛效果的影响。方法收集2013年6月至2016年1月在该院接受剖宫产分娩的产妇118例,按照随机数字表法分为观察组及对照组各59例,观察组产妇接受腰硬联合麻醉,对照组产妇接受硬膜外麻醉。手术前1d(T0)、剖宫产结束前10min(T1)、剖宫产术后6h(T2),采用全自动血凝分析仪测定凝血功能指标,采用放射免疫法测定肾素-血管紧张素-醛固酮系统(RAAS)功能指标。术后6h(T2)、术后12h(T3),采用痛阈测试仪测定疼痛指标。结果 T1、T2时,观察组产妇的凝血指标凝血酶原时间(PT)、活化部分凝血酶原时间(APTT)、凝血酶凝固时间(TT)水平均显著高于对照组产妇,凝血酶原活动度(PTA)水平低于对照组产妇(P0.05);观察组产妇的血清RAAS指标肾素(R)、血管紧张素Ⅱ(ANGⅡ)、醛固酮(ALD)水平均低于对照组产妇(P0.05)。T2、T3时,观察组产妇的视觉模拟评分(VAS)评分值低于对照组产妇,痛阈、耐痛阈水平高于对照组产妇(P0.05)。结论腰硬联合麻醉可减少剖宫产创伤引起的产妇凝血、RAAS功能激活,且在术后镇痛方面效果更显著。

Influence of combined spinal-epidural anesthesia on perioperative coagulation function,RAAS activity and postoperative analgesia effect in parturients with cesarean section

Objective To study the influence of combined spinal-epidural anesthesia on perioperative coagulation function,RAAS activity and postoperative analgesia effect in parturients with cesarean section.Methods One hundred and eighteen parturients of cesarean section in our hospital from June 2013 to January 2016 were collected and divided into the observation group and control group according to the random number table method,59 cases in each group.The observation group received the combined spinal-epidural anesthesia and the control group received epidural anesthesia.The coagulation function indicators on preoperative 1 d (T0),at 10 min before operation end(T1) and postoperative 6 h (T2) were detected by adopting the automatic blood coagulation analyzer,the renin angiotensin aldosterone system (RAAS) function indices were detectd by radioimmunoassay.The pain indicators at postoperative 6 h(T2),12 h (T3) were detected by the pain threshold test instrument.Results The levels of prothrombin time(PT),activated partial thromboplastin time (APTT) and thrombin time (TT) at T1 and T2 in the observation group were significantly higher than those in the control group,while the PTA level was lower than that in the control group(P<0.05);serum RAAS indices such as (renin),angiotensin Ⅱ(ANG II) aldosterone(ALD) in the observation group were lower than those in the control group(P<0.05).The VAS score at T2,T3 in the observation group was lower than that in the control group,while the pain threshold and pain tolerance threshold levels in the observation group were higher than those in the control group(P<0.05).Conclusion Combined spinal-epidural anesthesia can reduce the blood coagulation and RAAS activation caused by cesarean section trauma,and the effect of postoperative analgesia is more significant.
