摘要
目的:探讨腰麻阻滞平面与阑尾切除术中牵拉反应的关系。方法:203例腰麻下行阑尾切除术患者,按阻滞平面的不同分为A组:高于T5;B组:等于T5;C组:等于T6;D组:低于T6。牵拉反应分Ⅰ￣Ⅲ级,记录每组中牵拉反应情况。结果:A、B、C组中Ⅰ级的发生率明显多于D组(P<0.01),而A、B组中Ⅰ级的发生率与C组比较均有显著性差异(P<0.01)。A、B两组Ⅰ级的发生率无统计学差异(P>0.05)。结论:在腰麻阻滞平面等于或高于T5时能较好地抑制阑尾切除术中牵拉反应;阑尾、阑尾系膜的感觉纤维是经T5或T6及以下某些节段的脊神经进入脊髓的。
Objective: To investigate the relationship between block levels of spinal anesthesia and traction reactions during appendectomy. Methods: Two hundred and three patients undergoing appendectomy, were divided into group A,B,C and D, according to block levels, which were above or at T5, at or below T6 respectively. The traction reactions were graded into Ⅰ,Ⅱ,Ⅲ.Conditions of traction reaction in each group were recorded. Results: The incidences of grade Ⅰtraction reactions were significantly higher in group A,B,C than that in group D, respectively(P < 0.01). The incidences of grade Ⅰtraction reactions in group A,B were different from that in group C respectively(P < 0.01). The incidences of grade Ⅰtraction reactions were not different between group A and B(P > 0.05). Conclusion: When block levels of spinal anesthesia were above or at T5, the traction reactions during appendectomy would be inhibited adequately;the sensory fibers of vermiform appendix, mesoappendix enter the spinal cord through the dorsal roots of T5 or T6, and through some dorsal roots below T5 or T6.
