52 patients were studied under two different inflation pressure so as to find out the proper inflation pressure in the upper extremity operation. Analyzing the hemostasis effect and EMG of the upper extremity under different inflation pressre, it suggested that when the air tourniquet is used in the upper extremity operation the traditionally used pressure (33.3-40.0 kPa) of the air tourniquet should be changed according to the patient's condition. Usually good hemotasis effect could be obtained under the pressure of 4.0-6.6 kPa, which is more than the systolic pressure of the brachial artery.
对52例患者在两种不同的充气压力下进行研究，以找出上肢手术中的合适充气压力。通过分析不同充气压力下上肢的止血效果和肌电图，结果表明，在上肢手术中使用气压止血带时，传统使用的气压止血带压力（33.3 - 40.0千帕）应根据患者情况进行调整。通常在4.0 - 6.6千帕的压力下可获得良好的止血效果，该压力高于肱动脉收缩压。
