Abstract

Objective: To study the effect of fisting activities at different frequencies on hemodynamics of the vein with peripherally inserted central catheter(PICC) and compared with that of the vein in patients with supine resting state． Methods: PICCs were randomly inserted in 10 adult volunteers. Variations of the inner diameter of the vein, cross-sectional area, mean velocity of blood flow, blood flow volume of the vein with PICC were evaluated by using color Doppler ultrasound for 3 minutes with four different frequencies including 40 times/min; 30 times/min; 20 times/min and 10 times/min. Results: Compare to the vein in supine resting state, all of the four fisting activities with different frequencies enlarge the inner diameter and cross-sectional area of the vein(P＜0.05). The fisting activity with the frequency of 30 times/min significantly increase the mean blood flow velocity(P＜0.05). The blood volume during fisting activities with frequency of 30 times/min and 20 times/min was higher than that of the other two frequency activities(P＜0.05), and the effect was most obvious during the 30 times/min. Conclusion: The frequency of 30 times/min fisting activity produces the best hemodynamic effect, espicially for the best mean blood flow velocity and blood flow volume, it can be used as a way to prevent upper extremity vein thrombosis related to PICC insertion.
