气压止血带充气前两种不同驱血方法的对比研究

Comparison of two different blood-evacuation methods before inflation of pneumatic tourniquet

目的观察气压止血带充气前两种不同驱血方法的驱血效果。方法选取2016年1月—2017年6月下肢手术使用止血带的患者100例。根据驱血方法不同分为对照组(驱血带驱血)和观察组(双手挤压驱血),各50例,通过患者手术前收缩压加150 mmHg设定术中止血带所需压力值,记录术中驱血至止血带充气结束所用时间、止血效果、并发症的发生率。结果观察组驱血至止血带充气结束所用时间为(4.32±1.70)min,少于对照组的(5.45±2.82)min(P<0.05)。2组止血效果差异无统计学意义(P>0.05)。观察组术后并发症发生程度较对照组轻微(P<0.05)。结论双手挤压法操作简便,具有驱血效果良好和并发症少的优点。

Objective To compare the effect of two different blood-evacuation methods before inflation of pneumatic tourniquet.Methods Totally 100 patients withlower extremity surgery were assigned to the control group(n=50)and the observation group(n=50)according to the different blood-evacuation methods.The rubber strap was used before inflation of pneumatic tourniquet in the control group,and the manual squeezing method was adopted in the observation group.The duration of blood-evacuation,efficacy of blood-evacuation and related complications were observed and compared between two groups.Results The duration of blood-evacuation in the observation group was shorter than that of the controls(4.32±1.70 min vs.5.45±2.82 min,P<0.05).There was no significant difference in efficacy of blood-evacuation between two groups(P>0.05).Patients in the observation group had a lower severity of related complications(P<0.05).Conclusion Manual squeezing method is an safety and effective blood-evacuation method before inflation of pneumatic tourniquet.
