摘要
目的比较钢丝加强聚脲胺酯硬膜外导管与聚氯乙烯硬膜外导管,在剖宫产麻醉时对不良事件发生的影响。方法 160例拟行腰硬联合麻醉下行剖宫产术的产妇,按随机数字表法分为聚氯乙烯硬膜外导管组(A组,n=80)和钢丝加强聚脲胺酯硬膜外导管组(B组,n=80),常规行腰硬联合阻滞操作,各组置入相应的硬膜外导管。记录硬膜外置管通畅情况、置管时感觉异常、回抽见血或脑脊液、穿刺误入血管、注药遇阻、拔除硬膜外导管难易情况、拔管后出血、术后感觉异常及术后1周内硬膜外血肿的发生情况。结果与A组比较,B组硬膜外置管时感觉异常、回抽见血或脑脊液、注药遇阻和术后感觉异常的发生率降低(p<0.05),其余指标差异无统计学意义(p>0.05)。两组术后均无硬膜外血肿压迫症状。结论采用钢丝加强聚脲胺酯硬膜外导管可降低剖宫产产妇置管时损伤神经及血管的发生率。
Objective To compare the influence of wire polyurethane epidural tube and polyvinyl chloride epidural tube on the incidence of adverse events in cesarean section. Methods 160 puerperants undergoing combined epidural and spinal anesthesia （CSEA）were randomized into wire polyurethane epidural tube group（ group A, n = 80）and polyvinyl chloride tube group （group B, n = 80）. Combined epidural and spinal anesthesia （CSEA） was performed routinely. The corresponding epidural catheter was inserted in each group. The catheterization without difficulty, paresthesia during catheterization, the number of patients in whom blood or cerehrospinal fluid was withdrawn from the epidural catheter, intravascular catheter insertion, injection obstruction, easiness during removal of the catheter, bleeding after removal, postoperative paresthesia and epidural hematoma within 1 week after operation were recorded. Results Compared with group A, the incidences of paresthesia during catheterization ,the number of patients in whom blood or cerebrospinal fluid was withdrawn from the epidural catheter,injection obstruction and postoperative poresthesia were significantly decreased （p 〈 0. 05 ）, and no significant change was found in the other parameters in group B （p 〉 0. 05 ）. No epidural hematoma occurred in both group 1 week after surgery. Conclusion Wire polyurethane epidural tube can decrease the occurrence of catheterization - induced damage to the nerve and blood vessels in anesthesia for cesarean section.
