经坐骨小孔阴部神经阻滞麻醉的解剖学探讨

AN INVESTIGATION ON THE POSSIBLE ROUTE OF INJECTION FOR BLOCKING ANETHESIA OF PUDENTAL NERVE THROUGH FOR AMEN ISCHI ADICUM MINUS (FROM THE VIEW-POINT OF REGIONAL ANATOMY)

摘要:

从36具尸体(72侧)坐骨的解剖观察,测得在坐骨小孔内,骶棘韧带与坐骨棘之间的浅面,由内向外排列的是阴部神经、阴部内动脉与阴部内静脉。阴部神经行经坐骨小孔段的表面定位为坐骨结节上方3.81±0.57厘米,相当于坐骨结节最突出点至骶骨角连线的上3/5与下2/5的交界点。临床上可经此点垂直于骶结节韧带进针至坐骨小孔作阴部神经阻滞麻醉。
