Abstract Objective To evaluate the effectiveness of intermittent pneumatic compression (IPC) in the prevention of DVT after hip arthroplasty.Methods From Jan.2013 to Dec.2014,consecutive patients treated with low dose Aspirin after hip arthroplasty were collected as thecontrol group.From Jan.2015 to Dec.2016,patients received both IPC and low dose Aspirin were included in the IPC group.We retrospectively collected and analyzed the demographic data such as age,gender,body mass index(BMI),time of operation,hospitalization period,and underlying disease for hip arthroplasty.A total of 778 patients were collected in this retrospective study.Among them,thecontrol group had 286 patients(157 males,129 females).The average age was(61.21±7.92).The IPC group had 492 patients(268 males,224 females).The average age was(60.48±8.04).The effectiveness of IPC in the prevention of DVT was evaluated through the comparison of DVT incidences between the two groups.Risk factors affecting the development of DVT were determined from age,gender,BMI,time of operation,and hospitalization period.Any complications related to the application of IPC would be collected as well.Results The mean follow-up time were(11.75±6.44)months and(11.02±6.69)months of the control group and the IPC group,respectively(P=0.134).There were no significant differences in most demographic data between the two groups.However,hospitalization period of the control group was significantly longer than that of the IPC group (P<0.001).There were 12 patients and 7 patients developing DVT in thecontrol group and the IPC group,respectively.The IPC group (1.4%) had a remarkably lower incidence of DVT than the control group did(4.2%),P<0.05.There was no IPC relating complication observed in the IPC group.The patients having DVT were older and stayed longer inthehospital than those not affected by DVT(P<0.05).Conclusion The results of the current study suggest that IPC might be an effective and safe option for the prevention of DVT after hip arthroplasty.
