Objective To explore the best single use duration of intermittent pneumatic compression(IPC)in pa-tients with total hip arthroplasty(THA)based on the patient tolerance.Methods A total of 120 patients who under-went total hip arthroplasty in our hospital from November 2021 to June 2022 was collected by convenient sampling,and were allowed to continue to receive IPC treatment within 24-48 hours after the operation without time limit until the patients requested to stop for any reason.The peak velocity(PV)and psychological acceptance of the patients'common femoral vein blood were measured 1 time at rest before the start(baseline),every 30 minutes,and at the end of the operation;Observe the bleeding volume of the wound were measured each one at rest before the start(baseline),every 1 hour,and at the end.The correlation between time length and peak blood flow rate was ana-lyzed.Results The average duration of IPC tolerance in 120 patients was(80.42+3.31)min,87.5％of patients could tolerate 60 min,and 96 patients(71.1％)asked to stop because of the influence of turning and other activi-ties;Compared with the PV at rest,the PVs at any time of IPC were statistically significant(all P＜0.05);Com-pared with PV at 60 min,90 min,120 min,150 min,and 180 min,there were statistically significant differences(all P＜0.001);Compared with PV at 90 min,120 min,150 min,and 180 min,there were statistically significant differences(P＜0.001,P＜0.001,P=0.003,P=0.031);There was no significant difference in PV between other tolerance durations(P＞0.05).IPC did not increase wound blood leakage for different use periods.Conclusion For conscious patients,taking into account patient tolerance and the promotion of venous blood flow rate,it is recom-mended to use IPC for a single time of 60min to 90min,which can increase the frequency of daily use or use ankle pump exercise during intermittent use.The recommended 18 hours per day in the guidelines may be considered for people with disturbance of consciousness.
