Abstract：Objective To investigate the effect of individualized inflation pressure setting of pneumatic tourniquet in surgical hemostasis in the limb orthopedic surgery. Methods 〓A total of 210 patients with limb orthopedic surgeries were randomly divided into blood pressure(BP)group, limb diameter(LD)group and traditional pressure(TP)group. The inflation pressure of pneumatic tourniquet was set based on the systolic pressure in the BP group, based on limb diameter in the LD group and based on the recommended value. The efficacy on surgical hemostasis, collateral damage and intraoperative agitation were observed and compared among three groups. Results 〓The inflation pressure of pneumatic tourniquet in BP group and LD group was lower than that in the TP group(P0.05). There was a better hemostatic effect in the BP group and LD group compared with that in the TP group(χ2=6.71,P=0.03;χ2=8.53,P=0.01). The evaluation on collateral damage in BP group and LD group was better than that in the LD group(χ2=9.76,P=0.01;χ2=9.14,P=0.01). Compared with patients in the LD group, patients in the BP group and LD group had a less severity of intraoperative agitation(χ2=9.95,P=0.02;χ2=10.65,P=0.01). Conclusion 〓The individualized inflation pressure setting of pneumatic tourniquet is effective to improve the hemostatic effect and reduce the risk of collateral damage in the limb orthopedic surgery.
