摘要
为了探讨硬膜外麻醉时交感神经紧张性的变化规律,作者利用电体温计对20例腰段硬膜外麻醉的病人进行了阻滞区域和非阻滞区域皮肤温度的测量。结果显示无论在低平面(T_(8.8±0.6))还是高平面(T_(5.09±0.28))麻醉时,未阻滞区域的皮肤温度与阻滞前比较均明显降低,前臂指尖皮温梯度也较阻滞前显著增加,而阻滞区域的皮肤温度则较阻滞前明显升高,并且针刺痛觉缺失平面常低于皮温升高之平面。从而提示硬膜外麻醉时皮温的变化,反映了交感神经紧张性的改变。
Changes of skin temperature were measured serially in 20 cases of lumbar epidural analgesia. The skin temperature of unblocked region decreased, while that of blocked region raised The sensory block area was narrower than that of temperature change. The author suggested; 1. skin temperature change might reflet indirectly the sympathetic tonicity, and was the function of sympathetic tonicily and regional blood flow. 2. The levels of sympathetic block was wider than sensory block during epidural analgesia.
