摘要
目的：将不同频率握拳运动置入PICC静脉血液动力学指标与静息平卧位比较，探讨握拳运动促进上肢静脉血液回流的最佳频率。方法：10名置入PICC的自愿受试者均接受40次/min、30次/min、20次/min、10次/min 4种频率握拳运动，4种握拳运动顺序按随机法确定，每种方法进行3 min。用彩色多普勒超声检测PICC置入静脉在静息平卧状态及4种握拳运动的血管内径、血管截面积、平均血流速度、血流量。结果：4种握拳运动的血管内径、血管截面积均较静息平卧状态增加，差异有统计学意义（P＜0.05）；平均血流速度仅频率30次/min握拳运动增加显著（P＜0.05）；血流量比较，频率30次/min、20次/min优于其他两种握拳方法（P＜0.05），以30次/min最佳。结论：频率30次/min握拳运动血流动力学效果最佳，主要表现为平均血流速度和血流量均显著增加，可作为预防PICC相关上肢静脉血栓的参考。
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.
