压力泵对剖宫产后股静脉血流的影响

目的 探讨压力泵对股静脉血流的影响,为产后卧床患者寻求新的促进下肢静脉回流的方法,从而更有效地预防下肢静脉血栓的形成.方法 将120例患者随机分为观察组和对照组各60例,观察组使用压力泵,对照组采用主动活动踝关节,用彩色多普勒血流显像仪检测手术前后静止状态下股静脉的血流速度.结果 两组患者比较,术前静止、术后静止及活动2 min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)；两组患者比较,1 min时点差异无统计学意义,3 min、5 min、15 min时点差异有统计学意义(P＜0.05),两组患者各时点股静脉血流速度较静止时均明显加快(P＜0.05)；各时点血压、心率无明显影响；手术创面无明显出血.结论 剖宫产患者产后卧床期间股静脉血流速度明显减慢；下肢加压及主动活动踝关节均能增加股静脉血流速度而且具有一定的安全性.

Effect of pressure pump on femoral venous blood flow of parturient after caesarean section

Objective To investigate the effect of pressure pump on femoral venous blood flow of parturient after caesarean section,and provide new methods of promoting lower limbs venous reflux for parturient in bed after caesarean section.Methods A total of 120 patients were divided into two groups,60 cases were in experimental group and 60 cases in control group.The speeds of femoral venous blood flow at different time were measured by Doppler ultrasound examination.Results In two groups,after operation,the speed of FVBF was significantly decreased compared to that of before operation (P ＜ 0.05 ).Lower limb exercises for 2 to 4 minutes markedly increased FVBF ( P ＜ 0.05).Under two groups of patients'exercises various points in time FVBF to move obviously sped up ( P ＜ 0.05 ) ; There were no changes in the parameters of heart rate and blood pressure.Conclusions Pressure pump therapy apparatus and lower limb exercise can markedly increase FVBF (P ＜ 0.05),moreover has certain security.
