To investigate the effects of intermittent pneumatic compression(IPC)on blood flow of deep veins in lower limbs in patients after laparoscopic radical resection of rectal cancer.

A total of 82 patients undergoing laparoscopic radical resection of rectal cancer were selected from September 2017 to February 2019 in Eastern Branch of Renji Hospital Affiliated to Medical School of Shanghai Jiaotong University, and the patients were randomly divided into experimental group(36 cases)and control group(46 cases). The control group received routine treatment, while the experimental group was treated with IPC during operation.The diameter(mm), the maximum blood flow velocity(cm/s)and blood flow(ml/s)of femoral vein were measured by color Doppler ultrasonography before placement of lithotomy position during operation and before lower limbs were laid down at the end of operation in both groups.The correlations between the hemodynamic change in femoral vein before and after operation and the clinical data of the two groups were compared and analyzed.

There were significant differences in the changes before and after operation of velocity, flow and diameter of femoral vein between the two groups(P<0.01).

IPC can effectively improve the hemodynamic indexes of deep veins of lower limbs and blood circulation in patients undergoing laparoscopic radical rectal cancer.It is effective to prevent the occurrence of deep venous thrombosis of lower limbs after operation.
