运动下肢对肺大泡持续负压吸引患者静脉血流的影响

Effects of Lower Limb Exercise on Femoral Venous Blood Flow in Aged Patients

目的探讨活动下肢对股静脉血流的影响,为肺大泡持续负压吸引患者寻求新的活动下肢的方法,从而更有效地预防下肢深静脉血栓的形成。方法采用自身对照的方法,用彩色多普勒血流显像仪检测手术前后静止状态下、主动活动与被动活动中股静脉的血流速度。结果观察组与对照组比较,术前静止、术后静止及活动2min差异无统计学意义(P>0.05);两组患者术后卧床较术前静卧时股静脉血流速度均明显减慢(P<0.05);两组比较,2min时点差异有统计学意义,1min、3min和4min时点差异无统计学意义(P>0.05),两组患者下肢锻炼各时点股静脉血流速度较活动前均明显加快(P<0.05);各时点被动与主动锻炼下肢对血压、心率无明显影响;活动中及活动后手术创面无明显出血。结论老年患者术后卧床期间股静脉血流速度明显减慢;被动与主动活动下肢均能增加股静脉血流速度而且具有一定的安全性。

Objective To investigated the effects of lower limb exercises on femoral venous blood flow in lie in bed patients. Method 60 patients be obseved. Femoral venous blood flow at different time was measured by Doppler ultrasound examination. Results Under two groups of patients＇ exercises various points in time FVBF to move obviously speeds up （P〈 0.05） ; There were no changes in the parameters of heart rate. Conclusion Lower limb exercise by passive activity and initiative activity markedly increased FVBF（ P〈（0.05 ） ,moreover has certain security.
