动静脉脉冲系统预防股静脉置管术后深静脉血栓的效果观察

目的：探讨预防股静脉置管术后深静脉血栓（ DVT）形成的有效方法。方法采用回顾性分析方法，将使用动静脉脉冲系统治疗前的58例危重患者设为对照组，使用动静脉脉冲系统治疗后的62例危重患者设为观察组，对两组患者股静脉置管术后DVT形成情况进行比较。结果观察组患者股静脉血流峰速度、平均速度、大腿周径、小腿周径变化值分别为（47．2±6．3） cm/s，（29．5±4．5） cm/s，（8．0±0．5）cm，（4．0±0．3） cm，对照组分别为（27．6±5．1） cm/s，（18．1±2．3） cm/s，（9．8±0．2） cm，（5．6±0．4）cm，两组比较差异有统计学意义（t分别为18．785，17．636，-25．564，-24．892；P＜0．05）；观察组患者发生血栓5例，术肢肿胀例数7例，对照组分别为12，15例，两组比较差异有统计学意义（χ2分别为3．928，4．250；P＜0．05）；两组患者术肢肿胀程度及血栓形成程度比较，差异有统计学意义（Z值分别为50．500，19．500；P＜0．05），两组患者的舒适度及满意度比较差异有统计学意义（χ2值分别为8．628，12．684；P＜0．05）。结论动静脉脉冲系统能有效预防危重患者股静脉置管术后DVT的形成。

Effect of arteriovenous impulse system to prevent deep venous thrombosis after femoral vein indwelling catheter

Objective To discuss the effective method to prevent deep venous thrombosis （ DVT） after femoral vein indwelling catheter .Methods Retrospective analysis was used to divide 120 critical patients into two groups： the control group was patients before the treatment of arteriovenous impulse system while the observation group was patients after the treatment .DVT in both groups were compared after femoral vein indwelling catheter .Results The changes of blood flow peak speed of femoral vein , average speed , thigh weeks diameter and crus weeks diameter were respectively （47.2 ±6.3 ）cm/s,（29.5 ±4.5）cm/s,（8.0 ±0.5）cm, （4.0 ±0.3） cm in the observation group, and （27.6 ±5.1） cm/s,（18.1 ±2.3） cm/s,（9.8 ±0.2） cm, （5.6 ±0.4）cm in the control group, with statistically significant differences （t=18.785,17.636,-25.564,-24.892, respectively;P〈0.05）.There were 5 cases of DVT and 7 cases of surgery limb swelled in the observation group , 12 cases of DVT and 15 cases of surgery limb swelled in the control group , and the differences were statistically significant （χ2 =3.928,4.250, respectively; P 〈0.05）.There were also statistically significant differences of degree of swelling and DVT between two groups （ W=50.500, 19.500, respectively;P〈0.05）.And patients’ comfort and satisfaction were significantly different （χ2 =8.628, 12.684, respectively; P 〈0.05）.Conclusions Arteriovenous impulse system can effectively prevent DVT after femoral vein indwelling catheter .
