| 1. 根据患者的年龄，体重，手术部位是上肢或下肢选用合适的袖带（上肢：短、窄；下肢：长、宽）。 1. according to the patient's age, weight, surgical site is the upper or lower extremity proper cuff (Upper: short and narrow; lower extremity: length, width). 2. 袖带不能直接接触皮肤，而应用棉纸覆盖在皮肤表面，然后绑袖带。 The 2. cuff is not in direct contact with the skin, and the application of tissue covering on the surface of the skin, and then tied the cuff. 3. 选择缚扎部位上肢应在肱骨上1/3段；下肢在大腿根部（因上肢避开了桡神经，下肢容易直接压迫股动脉，但也有报道认为对于下肢远端的手术，止血带的袖带越宽，四肢的周径越小，阻断血流所需的压力就越低，使用者就越舒适，因此建议足趾手术时，止血带最好放置在踝上方） 3. select the binding site on the humerus upper limb should be 1/3; lower limb in the thigh (for upper limb to avoid radial nerve, lower extremity to direct compression of the femoral artery, but there are also reports that for lower extremity surgery, the tourniquet cuff is wide, limb circumference is small, blocking the blood pressure is required low, users more comfortable, so suggest toe surgery, tourniquet is best placed above the ankle) 4. 接通气管，检查接头处是否衔接紧密、袖带内气囊是否漏气。 4. on the trachea, check whether the joint is tightly linked, cuff balloon for leaks. 5. 设定压力值：为了避免局部组织损伤及神经干挤压伤，同时又要达到理想的止血目的，止血带的设定压力要根据局部组织薄厚、患者年龄、肢体周径大小及局部动脉收缩压而定。上肢为收缩压的1.5倍，下肢为收缩压的2倍 5. set pressure value: to avoid local tissue injury and neural stem crush injury, while at the same time to achieve hemostasis ideal, set pressure tourniquet according to local tissue thickness, age, limb circumference size and systolic blood pressure and local. The upper limb is 1.5 times the systolic pressure, and the lower extremity is 2 times the contraction pressure. 6. 设定时间：上肢一般不超过60 min，下肢不超过90 min。若手术时间长，则应让肢体恢复血流10～15 min，然后再阻断。 6. setting time: the upper limb is generally not more than 60 min, and the lower extremities are not more than 90 min. If the operation time is long, the blood flow of the limb should be restored to 10~15 min, and then the blood flow should be blocked again. 7. 加压：止血带加压前，先将肢体抬高3 min左右，加速静脉血回流，以减少肢体血量。 7. pressure: before the tourniquet is pressurized, the body is raised about 3 min, and the venous blood flow is accelerated in order to reduce the blood volume of the limbs. 8. 及时记录充气时间，术中注意加强对患者呼吸、循环功能的监测。 8. to record the inflating time in time, and to strengthen the monitoring of the respiratory and circulatory function of the patients during the operation. |
