Effect of hemoperfusion cartridge on different internal environmental indicators.

BACKGROUND This study aimed to observe the effect of hemoperfusion (HP) cartridge on different internal environment indicators at different time points in patients with acute blood poisoning and to find alternative indicators for the detection of blood poisoning. METHODS The levels of internal environment indicators (blood pH, PvCO2, PvO2, blood lactate, potassium, free calcium, bicarbonate, and blood glucose) before and after HP treatment were recorded for patients with acute poisoning at time points of 30 minutes and 120 minutes. After calculating the difference value δ, the statistical software was used to analyze the statistical difference of the influence caused by HP cartridge at two time points. According to the formula, adsorption rate % = ×100, the adsorption rate of each indicator was calculated respectively. RESULTS The difference of indicators at different time points in inlet and outlet such as blood glucose, free-calcium, and lactate was statistically significant (P<0.05), but the difference in indicators such as pH, PvCO2, PvO2, potassium, sodium, and bicarbonate was not statistically significant (P>0.05). CONCLUSION During HP treatment, the indicators of blood glucose, free-calcium and lactate were significantly affected by HP cartridge, and the effect varies with time.
