摘　　要：目的探讨上肢气囊止血带不同充气压力对手术效果的影响。方法选取60例健康成年志愿者按右上臂周径大小分为A、B、C三组,A组上臂周径≤25 cm,B组上臂周径26～30 cm,C组上臂周径>30 cm,监测右肱动脉基本阻断时气囊止血带的充气压力值,测得A、B、C组平均充气压力值分别为(25.12±1.11)kPa、(28.32±1.51)kPa、(32.51±1.22)kPa。将120例上肢手术患者随机分成观察组和对照组各60例。对照组按传统充气压力值(33.33～40.00kPa)充气阻断术野血流,观察组按照肢体周径大小选择同健康志愿者相同压力值,观察两组患者手术中的止血效果及肢体损伤情况。结果两组患者的充气时间比较,差异无显著性意义(P>0.05)。观察组患者手术中止血效果及肢体损伤情况显著优于对照组(P<0.01)。结论根据肢体周径大小选择充气压力值,在达到止血效果的同时,能使组织损伤减轻到最低限度。Objective To explore effect of different pressures achieved from inflation of inflatable tourniquet ballon in operation. Methods Totally, 60 healthy volunteers were recruited and divided into 3 groups based on circumference of their right arms, with group A having a right-arm circumferenceS25 cm, group B 26～30 cm, and group C〉30 cm. And the inflated pressures of the right upper arm in group A,B,C averaged （25.12± 1.11 ）kPa, （28. 32 ± 1.51）kPa, （32.51±1.22）kPa respectively. A total of 120 patients who were going to receive a surgery at the upper arm were randomized into an observation group and a control group. Patients in the control group were given a pressure ranging from 33.33 kPa to 40.00 kPa, while their counterparts in the observation group were given the same pressure as the healthy volunteers were aecording to the same circumferences of their upper arms. Results The inflation time of the 2 groups had no significant difference （P〉0.05）, The haemostatic effects and limb injuries had significant difference in both groups （P〈0.01）. Conclusion When the inflation pressure are given based on patients＇ upper limb circumference, the haemostatic effects won＇t be undermined and tissue injury will be minimized.
