Abstract:
Objective To explore the effects of upper limb compression and clench fist on hemodynamics of upper of limbs veins among patients with peripherally inserted central catheter (PICC), so as to provide theoretical support for the new strategy of preventing PICC related thrombus.Methods From January to February 2018, we selected 71 patients with PICC in Chinese PLA General Hospital by convenience sampling. The self before-after control was used to measure peak velocity of blood flow at vein with PICC in patients' armpit when patients were in a calm state, the compression of the upper limb with PICC was 20, 40, 60 mmHg and after fists were clenched. SPSS 22.0 was used to analyze the change of blood flow peak velocity after compression and clench fist.Results The median of vein blood flow peak velocity was 7.61, 20.38, 18.48, 23.37 and 25.54 cm/s respectively when patients were in a calm state, after fists were clenched and when the compression was 20, 40, 60 mmHg with significant differences (F=278.97,P<0.01). The blood flow peak velocity after fists were clenched and the compression was 20, 40, 60 mmHg was higher than that when patients were in calm state; the blood flow peak velocity when the compression was 20 mmHg was lower than that when the compression was 40 and 60 mmHg (P<0.01). The blood flow peak velocity after fists were clenched had positive correlations with those after the compression was 20, 40, 60 mmHg respectively (r=0.66, 0.72, 0.71;P<0.01). In the oscillogram of hemodynamics, the change curve of blood flow rate was gentle after fists were clenched. However, the change curve of blood flow rate was abrupt when the compression for upper limb was 40 mmHg.Conclusions The compression for upper limb can effectively increase blood flow rate of upper limb vein to achieve the level of blood flow rate of upper limb caused by clenching fist. If clenching fist is replaced by upper limb compression to prevent PICC related thrombus, 40 mmHg may be the appropriate pressure value of compression.
