Objective:
This study discussed and analyzed the preventive value of intermittent pneumatic compression combined with early rehabilitation training for deep vein thrombosis (DVT) in patients undergoing total knee arthroplasty (TKA).
Methods:
During January 2019 to April 2020, 85 patients who underwent TKA in our hospital were selected as subjects, and were randomly divided into an observation group (n=44) and control group (n=41) by table of random numbers. The control group patients received conventional nursing care after TKA surgery, while the observation group received combinative treatment of intermittent pneumatic compression therapy and early rehabilitation training like the conventional treatment in the control group. Subsequently, the circumference and mobility of knee joint, hemorrheologic indexes and the incidence of DVT between the two groups of patients before and after surgery were compared.
Results:
The knee circumferences of the two groups on 3 d and 7 d preoperatively were higher than 1 d before surgery (P<0.05), and the indexes of the observation group on 3 d and 7 d preoperatively were lower than that of the control group (P<0.05). The range of motion (ROM) of the two groups 3 d postoperatively were higher than that before surgery (P<0.05), the ROM in observation group 7 d postoperatively was increased than 3 d postoperatively (P<0.05), and the observation group had higher ROM on 3 d and 7 d postoperatively than that of control group (P<0.05). The two groups of patients had insignificant difference in knee function before treatment (P>0.05); the knee function of the two groups after treatment was better than pretreatment (P<0.05), and the observation group was better than the control group (P<0.05). The observation group had lower DVT incidence than the control group (P<0.05).
Conclusion:
Combinative treatment of intermittent pneumatic compression and early rehabilitation training can effectively improve the postoperative knee function of patients undergoing TKA, promote recovery, and effectively prevent DVT. In conclusion, the combinative treatment is worthy of clinical application.
