下肢活动时间对老年前列腺术后患者股静脉血流速度的影响

Effects of lower limb exercise on femoral venous blood flow in aged patients after prostatectomy

目的 :监测不同时间下肢活动对股静脉血流速度的影响 ,为老年前列腺患者术后卧床期选择有效的活动时间 ,以预防下肢静脉血栓。方法 :采用自身对照 ,用彩色多普勒血流超声显像仪监测手术前后、活动中与活动后股静脉血流速度。结果 :术后卧床较术前静卧股静脉血流速度明显减慢 (t=2 .2 73,P <0 .0 5 ) ;下肢活动 2min时股静脉血流速度较活动前明显增加 (t=3.134 ,P <0 .0 5 ) ;活动 2min、5min后股静脉血流速度与术后静卧时比较无显著差异 (t =2 .2 46 ,P >0 .0 5 ) ;各时点下肢活动对心率、血压无明显影响 ;活动中肉眼观察未见到手术创面活动性出血。结论 :老年前列腺术后卧床期间股静脉血流速度明显减慢 ;下肢活动 2～ 4min/次能增加股静脉血流速度 ,且对心率、血压无明显影响。

Objective:To evaluate the effects of lower limb exercise on femoral venous blood flow (FVBF) in aged patients after prostatectomy. Methods:Nine patients who had undergone prostatectomy were included in this study. FVBF at different times was measured by Doppler ultrasound examination. Results:After operation,the speed of FVBF femoral venous blood flow was significantly decreased compared to that before operation in all patients ( P <0.05). Lower limb exercise for 2 to 4 minutes markedly increased FVBF ( P < 0.05 ). There were no changes in the parameters of heart rate and blood pressure during and after lower limb exercise. Conclusion:Lower limbs exercise for 2～4 minutes effectively increased FVBF in aged patients after prostatectomy.
