Effect of handgrip exercise on blood flow velocity and blood vessel diameter changes of basilic vein in patients with peripherally inserted central catheter / 中国实用护理杂志

ABSTRACT

Objective We observed influence of different handgrip exercise on the changes of blood flow velocity and blood vessel diameter of basilic vein before and after the PICC placement and discuss the best model for handgrip exercise.Methods 60 patients with PICC were chosen and divided into group A,B and C with 20 patients in each groups.Group A received routine guidance on unarmed handgrip exercise,group B used electronic handgrip,the frequency was 25 times/min,the time period was 2 min with 4 times a day,once every 4 hours,group C adopted the same model as that of group B and 6 times a day,once every 3 hours.The venous blood flow velocity and blood vessel diameter was measured by pulsed Doppler ultrasound one hour before the PICC placement and one hour,1 day,3 days,7 days,10 days,14 days,21 days after placement.Results The venous blood flow velocity before and after PICC placement had statistically significant differences at different time points (F=2.934,P ＜ 0.05).The effect of group B and C was better than that of the group A and group C showed the best effect.The blood vessel diameter before and after PICC placement had significant differences at different time points(F=3.940,P ＜ 0.05).There was significant differences in the blood vessel diameter 1h before and 1h after PICC placement.Conclusions Handgrip exercise can effectively promote the upper limb venous blood flow velocity in patients with PICC,but shows little effect on the blood vessel diameter.Using the electronic hand grip in weak tap position,25 times/min,2 min every time,and 6 times a day (once every 3 hours),can obviously promote the upper limb venous blood flow velocity.
