为了比较周期性充气加压和常规护理干预对骨科大手术后深静脉血栓形成的效果,本研究选取了骨科大手术后患者92例,随机分为实验组和对照组各46例。对照组患者实施常规护理干预,实验组在对照组的基础上,于术后1~2 h使用间歇性充气挤压泵(IPC)进行周期性充气加压,脚踝压力45mm Hg,小腿压力40mm Hg,大腿压力30mm Hg,充气15 s,放气45 s,即一个挤压周期l min。结果表明,实验组患者下肢深静脉血栓发生率、血流峰速度和增幅、血流平均速度和增幅、血流量和增幅均显著高于对照(p<0.01),且实验组患者舒适度感受优于对照组。周期性充气加压可以降低骨科大手术后的深静脉血栓发生率、改善血流动力学指标,可广泛应用于临床。
In order to compare the effects of periodic inflation and routine nursing interventions on deep venous thrombosis after major orthopedic surgery, 92 patients with major orthopedic surgery were randomly divided into experimental group and control group with 46 cases each. The patients in the control group were given routine nursing intervention. The experimental group was inflicted with intermittent inflatable compression pump (IPC) on the basis of the control group at 1 ~ 2 h postoperatively. The ankle pressure was 45 mm Hg and the calf pressure was 40 mm Hg , Thigh pressure 30mm Hg, inflated 15s, deflated 45s, that is, an extrusion cycle lmin. The results showed that the incidence of deep venous thrombosis in lower limbs, peak velocity and increase of blood flow velocity, mean velocity and amplitude of blood flow, blood flow and amplitude in experimental group were significantly higher than those in control group (p <0.01) In the control group. Periodic pneumatic compression can reduce the incidence of deep venous thrombosis after major orthopedic surgery, improve hemodynamic indicators, can be widely used in clinical.
