摘要
目的应用超声技术评价阻力消失法定位髂筋膜间隙的准确性。方法拟行髋部手术患者175例，在髂前上棘和耻骨结节间连线中外1／3交界处向尾端旁开2cm处进针，当感觉到2次突破感后，给予0．5％罗哌卡因30ml，经超声辨认药液扩散部位确定准确穿刺情况，并记录给药后20min感觉阻滞有效情况。结果经超声确定，应用阻力消失法定位髂筋膜间隙准确率56．6％。穿刺错误部位构成情况：髂筋膜浅层25例、髂腰肌内51例；准确定位于髂筋膜间隙的阻滞有效率为98．0％，而定位错误时阻滞有效率为82．9％。结论阻力消失法不能准确定位髂筋膜间隙。
Objective The evaluate the accuracy of loss of resistance technique for location of fascia iliaca compartment using ultrasound technique. Methods One hundred and seventy-five patients undergoing hip surgery were enrolled in the study. A line was drawn on the skin from the pubic tubercle to the anterior superior iliac spine and divided in three equal parts. The site of puncture was marked 2 cm distal to the point at which the lateral met the middle third of the line. The needle was inserted until a loss of resistance was felt twice （fascia lata and fascia iliaca）, at which point 0.5 % ropivacaine 30 ml was infused. Correct puncture was identified by visualized spread of local anesthetic solution under the guidance of ultrasound technique. The effective sensory block was recorded within 20 min after administration. Results The accuracy of loss of resistance method for locating the fascia iliac compartment was 56.6 % using ultrasound technique. There were 80 patients in whom fault site of puncture oc- curred： 25 cases in the superficial layer of the fascia iliac and 51 cases in the iliopsoas muscle. The rate of effec- tive block was 98.0 % for correct location and 82.9 % for fault location. Conclusion Loss of resistance technique cannot accurately locate the fascia iliac compartment.
