Abstract:
OBJECTIVE: To investigate the changes of hemorheology and blood lipid index in patients with occupational hand-arm vibration disease(OHAVD). METHODS: A total of 78 patients with OHAVD were selected as the OHAVD group, and 78 workers without hand transmitted vibration exposure were selected as control group by judgment sampling method. The hemorrheology and blood lipid indexes of the two groups were detected. RESULTS: The whole blood viscosities(low-, medium-and high-shear), hematocrit, erythrocyte aggregation index, and abnormal rate of whole blood viscosities(mid-and high-shear) in the OHAVD group were higher in the OHAVD group than that in the control group(P<0.05). The erythrocyte deformability index and erythrocyte electrophoresis index were lower in the OHAVD group than that of the control group(P<0.05). In the vibration-induced white finger(VWF) subgroup of the OHAVD group, the whole blood viscosity(low-, medium-and high-shear), hematocrit were increased(P<0.05), and the abnormal rate of whole blood viscosity(high-shear) was higher(P<0.017) than that of the control group.The whole blood viscosity(medium shear), hematocrit and erythrocyte aggregation index were increased in the non-VWF subgroup than that of the control group(P<0.017). The concentration of low density lipoprotein cholesterol in the OHAVD group and non-VWF subgroup was higher than that in the control group(P<0.05). The whole blood viscosity(low-, medium-and high-shear), hematocrit, erythrocyte deformability index, erythrocyte aggregation index and erythrocyte electrophoresis index were not correlated with the length of service and age in the OHAVD group(P>0.05). CONCLUSION: The changes of hemorheological properties and blood lipids in OHAVD patients may be associated with vibration vascular injury.
