Objective To investigate the composition of particulate matter in hemodialysis and to explore the influencing factors of particulate matter formation. Methods The composition of the particles was determined by chemical experiments and electron microscopy. Fifty-four outpatients in hemodialysis centers were divided into pellets and non - particulate groups (34 and 20 cases). Thirty-four variables were collected by literature review and their influencing factors were analyzed. Results The particles were white thrombus, formed by aggregated platelets and fibrin aggregates, and embedded in a small amount of red blood cells. Logistic regression analysis showed that low molecular weight heparin was statistically significant (OR = 1.001, P <0.01). In addition, male, smoking, dry weight, hypersensitive C-reactive protein, venous pressure, dialysate temperature, blood vessel thrombosis and granule formation were statistically significant (P < 0.05). Conclusions To improve the degree of attention to white thrombosis, the injection of low molecular weight heparin sodium into the machine before the vascular access intravenous injection, for the analysis of the results to take appropriate care measures to reduce the production of white thrombosis is important, and can be white thrombosis. The repeated formation is seen as a sign of blood vessel thrombosis Key words: Hemodialysis; Particulate matter; Intravenous pot; White thrombus; Scanning electron microscope
