Abstract
Objective:To probe into the best fist frequency for promoting upper extremity vemous blood acceler-ation and recovery in PICC patients.Methods:A total of 30 healthy volunteers and 10 patients with PICC were selected as research obj ects the maximum blood flow velocity(Vmax)and mean blood flow velocity(TMFV)of axillary vein were measured respectively at rest,continuous fist 10 times,15 times,20 times,25 times,30 times, 35 times,40 times,and every 10 mins after movement stop by using color Poppler ultrasound.Results:Vmax and TMFV in healthy crowd and PICC patients after fist movement increased compared resting (P<0.05),af-ter continuous 25 times the velocity of blood flow increased to the peak,Vmax and TMFV recovered close to the resting state 40 min after stopping fist.Conclusion:The effcet of blood flow dynamics was the best in contincous fist 25 times,which mainly showed that the Vmax and TMFV significantly increased,after 40 mins of supining, blood flow tended to resting state,so it could provide reference for preventing PICC related upper venous throm-bosis.关键词
