To investigate the effect of two kind of air pressure cuff in assisted thrombolytic therapy for patients with deep vein thrombosis (DVT) of lower extremities.

A total of 80 patients with DVT of the lower extremities who were admitted to our hospital from June 2018 to June 2020 were selected and divided into a control group and a study group using a random number table method, with 40 casesin each group. Patients in the control group used traditional sphygmomanometer cuff, while patients in the study group used intelligent type of air pressure cuffs. Leg swelling fade-away rate, mean thrombus clearance rate and patient's comfort degree between two groups were compared.

The study group was better than the control group in terms of the Leg swelling fade - away rate, mean thrombus clearance rate and patient's comfort degree at different time points (3 days, 5 days and 7 days), with statistical significance (P < 0.05).

Compared with the traditional sphygmomanometer cuff, the application of intelligent type of air pressure cuff assisted thrombolytic therapy has better curative effect, and the patients have higher tolerance and comfort. Therefore, intelligent type of air pressure cuff has more advantages and is worthy of clinical application.
