        1. 根據患者的年齡,體重,手術部位是上肢或下肢選用合適的袖帶(上肢:短、窄;下肢:長、寬)。 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. 袖帶不能直接接觸皮膚,而應用棉紙覆蓋在皮膚表面,然后綁袖帶。 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. 選擇縛扎部位上肢應在肱骨上1/3段;下肢在大腿根部(因上肢避開了橈神經,下肢容易直接壓迫股動脈,但也有報道認為對于下肢遠端的手術,止血帶的袖帶越寬,四肢的周徑越小,阻斷血流所需的壓力就越低,使用者就越舒適,因此建議足趾手術時,止血帶最好放置在踝上方) 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. 接通氣管,檢查接頭處是否銜接緊密、袖帶內氣囊是否漏氣。 4. on the trachea, check whether the joint is tightly linked, cuff balloon for leaks. 5. 設定壓力值:為了避免局部組織損傷及神經干擠壓傷,同時又要達到理想的止血目的,止血帶的設定壓力要根據局部組織薄厚、患者年齡、肢體周徑大小及局部動脈收縮壓而定。上肢為收縮壓的1.5倍,下肢為收縮壓的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. 設定時間:上肢一般不超過60 min,下肢不超過90 min。若手術時間長,則應讓肢體恢復血流10——15 min,然后再阻斷。 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. 加壓:止血帶加壓前,先將肢體抬高3 min左右,加速靜脈血回流,以減少肢體血量。 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.
