Abstract

Abstract: This article discussed the difference in the application effect of different approaches of ultrasound-guided sciatic nerve block in the operation of elderly femoral intertrochanteric fractures. Eighty elderly patients with femoral trochanteric fractures treated by orthopedic surgery were selected for clinical research, which were divided into group A and group B, with 40 patients in each group. Both groups were treated with general anesthesia + ultrasound-guided sciatic nerve block anesthesia. The group A nerve block approach adopted the upper lateral popliteal approach, and the B group adopted the lower lateral approach of the greater trochanter. The results showed that the operation completion time, number of punctures, needle depth, in group A were lower than those in group B (P<0.05), and the duration of nerve block in group A was longer than that in group B (P<0.05); The VAS score of group A was lower than that of group B at rest 24 h after surgery (P<0.05), and the VAS score of group A was lower than group B at 12 h and 24 h after coughing (P<0.05). It can be seen that in general anesthesia + ultrasound-guided sciatic nerve block anesthesia, the upper and lateral popliteal approach is used. The larger subtrochanterial lateral approach has advantages including shallower needle penetration, fewer punctures, shorter operation time, and lighter postoperative pain.
