（1）正确选择止血带的缚扎部位，防止神经压伤。

(1) correctly select the binding site of the tourniquet and prevent nerve compression.

（2）选用合适的棉纸做衬垫（宽度超过袖带2～4 cm为宜），平整缚扎，保护受压皮肤，再将止血带平整地缚扎其上，松紧度以一指为宜并在外系好固定带，防止充气后滑脱；远离切口10～15 cm，便于无菌操作，防止感染；通气管要放在肢体近端，避免污染手术野，又易于打气。

(2) selecting suitable cotton paper liner (2 ~ 4 cm width over cuff advisable), smooth bound, compression of protecting skin, and then put a tourniquet neatly tied to plunge into it, but with a finger advisable and fasten belt, fixed out after filling to prevent slippage. Stay away from the incision for 10 to 15 cm and facilitate sterile operation to prevent infection. The ventilator should be placed in the near extremity of the limb, avoiding the contaminated operation field and making it easy to breathe.

（3）消毒皮肤时应做好止血带部位皮肤的保护，防止消毒液渗透。

(3) when disinfecting the skin, it should be protected by the skin of the tourniquet and prevent the infiltration of the disinfectant.

（4）严格掌握使用时间及压力控制。老人、小孩及身体虚弱者应适当降低压力值（上肢200 mmHg；下肢不超过250 mmHg）及缩短上止血带时间（尽可能控制在1 h内），听见报警音应及时做好放气准备。

(4) use time and pressure control strictly. The elderly, children and weak people should decrease the pressure value (upper 200 mmHg; lower limb is not more than 250 mmHg) and shorten the tourniquet time (as far as possible control within 1 h), hear the alarm sound should be prepared to put gas in a timely manner.

（5）注意调节好室温，室温高时要相应地缩短上止血带时间。

(5) be careful to adjust the room temperature, and shorten the time of the tourniquet when room temperature is high.

（6）四肢远端及末端骨折手术可联合应用止血带和驱血带。驱血始于骨折近端以上，避免了因驱血带挤压骨折断端所导致的脂肪栓塞以及急性肺动脉栓塞等严重并发症的发生，同时又达到了减少出血量的目的，效果良好。但动脉硬化、血栓闭塞性脉管炎及淋巴炎等患者一般不使用止血带；恶性肿瘤或局部炎症的患者，可使用止血带，但不驱血，以免瘤细胞或炎症进入血液，扩散到全身。

(6) the operation of distal and terminal fractures can be combined with a tourniquet and a blood drive. Drive blood began in proximal fractures above, to avoid the for drive belt blood fat embolism caused by extrusion of fracture end and serious complications such as acute pulmonary embolism achieved the purpose of reducing the bleeding again at the same time, the result is good. But patients with atherosclerosis, thrombosis, and lympholitis generally do not use a tourniquet. Patients with malignant or local inflammation may use a tourniquet, but do not exorcise blood to prevent tumor cells or inflammation from entering the blood and spreading to the whole body.

（7）双侧肢体同时应用止血带时，不能同时放气。如需继续应用，应待肢体恢复血流10～15 min后再重新抬高患肢充气（充气时间应逐渐缩短，间歇时间要相对延长，以缩短肢体缺血、缺氧时间，应用止血带的总体时间不超过5 h）。

(7) when you apply a tourniquet, you can't breathe at the same time. If you want to continue to apply, you should stay body restore blood flow up again after 10 ~ 15 min limb inflatable, inflatable time should be gradually shortened, intermittent time longer, than to shortening the time of limb ischemia, hypoxia, applied a tourniquet overall time not more than 5 h).

（8）放气时应将伤口加压包扎好的手术肢体抬高。

(8) when air is released, the wound should be pressurized and the body raised.
