Study on the curative effect of ankle pump exercise in prevention and treatment of deep venous thrombosis of lower extremity during perioperative period of knee arthroscopic surgery
Objective To investigate the preventive effect of ankle pump exercise in the prevention and treatment of deep venous thrombosis of lower extremity during perioperative knee arthroscopy.Methods A total of 100 patients who underwent arthroscopic anterior cruciate ligament reconstruction in sports medicine department of our hospital from January 2021 to December 2022 were selected and divided into the whole course group,the postoperative group,the anticoagulation group and the control group by simple random sam-pling method,with 25 cases in each group.In the whole course group,patients received ankle pump exercise from admission to discharge.In the postoperative group,patients started ankle pump exercise immediately af-ter awaking from surgical anesthesia until discharge.In the anticoagulation group,hypodermic injection of low molecular weight heparin sodium was given to prevent thrombus until discharge,and ankle pump exercise was not performed.The control group could not exercise ankle pump and prevent thrombus with drugs,and the af-fected limb was moved regularly after surgery.D-dimer and lower limb blood vessel color Doppler ultrasound were performed before and on the 3rd day after operation to detect the occurrence of lower limb thrombosis in the four groups.Results A total of six cases of thrombus occurred in the control group(24.0%).The inci-dence of thrombus in the postoperative group,the whole course group and the anticoagulation group was 0.The incidence of thrombus in the postoperative group,the whole course group and the anticoagulation group was significantly different from that in the control group(χ2=12.471,P<0.001).There was a statistically significant difference in BMI between the hypercoagulable group and the non hypercoagulable group(P<0.05).The incidence of hypercoagulability in the control group[64.0%(16/25)]was significantly higher than that in the postoperative group[24.0%(6/25)],the whole course group[12.0%(3/25)],and the anti-coagulation group[0(0/25)],with statistical significance(P<0.05).Conclusion Regular ankle pump exer-cise during perioperative operation under knee arthroscopy could effectively prevent deep venous thrombosis of lower extremity.Ankle pump exercise is economical,practical and worth promoting and applying.
