Forty patients with fractured neck of femur were allocated randomly to undergo surgery under general anaesthesia (GA) or subarachnoid anaesthesia (SAB). After operation, the incidence of deep vein thrombosis (DVT), assessed by venography, was found to be 40% in the SAB group, which was significantly lower than the incidence (76.2%) in the GA group. These observations may account for the previously reported effect of SAB, in comparison with GA, in reducing early postoperative mortality in this category of patient.
40例股骨颈骨折患者被随机分配接受全身麻醉（GA）或蛛网膜下腔麻醉（SAB）下的手术。术后，通过静脉造影评估发现，SAB组深静脉血栓形成（DVT）的发生率为40%，显著低于GA组的发生率（76.2%）。这些观察结果可能解释了先前报道的与GA相比，SAB在降低此类患者术后早期死亡率方面的作用。
