Effect Of Intermittent Pneumatic Compression On Deep Venous Hemodynamics Of Lower Limb In Patients Undergoing Rectal Cancer Resection

ObjectiveTo evaluate the preventative effect of IPC on the development of deep venous thrombosis of lower extremity via clinical analysis of the IPC effect on the deep venous hemodynamics of lower limb and the function of coagulation in patients subject to rectal cancer surgery.Methods120patients undergoing rectal cancer resection were randomly divided into non IPC group (control group, n=60) and IPC group (n=60). The control group received the routine treatments after surgery and the IPC was treated with IPC in addition to conventional treatments. The prothrom-bin time (PT), activated partial thromboplastin time (APTT), fibrinogen (FIB), international normalized ration (INR) and volume of D-dimer were detected at the last day before operation and1st,3rd,5th,7th day after surgery. Meanwhile, external iliac, caliber of femoral vein and popliteal vein, blood flow rate were examined for the average blood flow rate calculationand blood flow by color Doppler ultrasound.Results8patients in the control group encounter lower limb DVT, the incidence rate of which was13.33%; the number of lower limb DVT in the IPC group was1and the incidence was1.67%. The comparison indicated the statistic significance of difference in lower limb incidence rate (P<0.05); one day after the surgery, little obvious change in PT, APTT and INR shown in the detection (P>0.05); FIB and D-D both increased(P<0.05), which presented no significant difference among the two group (P>0.05); as the prolong of the surgery time, PT in the two group shortened gradually(P<0.05), APTT and INT present little significant change, FIB and D-D increased gradually, no significant difference could be seen at the same time (P>0.05). Through the examination of both lower limbs with color ultrasonography, average blood flow rate of the deep veins of lower limb and blood flow volume were lower than those of the IPC group, the difference of which bore significance in statistics (P<0.05).ConclusionThrough regular inflation and exhaustion, IPC could change the deep veins of lower limb hemodynamics indexes of the patient receiving rectal cancer surgery, which would prevent the lower limb DVT efficiently, It is a safe, simpleand convenient physiotherapy. Further clinical application is strongly recommended.
