Effect of high volume hemofiltration on canine oleic acid lung injury / 中华肾脏病杂志

ABSTRACT

Objective To investigate the effects of high volume hemofiltration(HVHF) on cardiopulmonary functions and IL-?plasma levels in lung injury models. Methods Sixteen dogs with oleic acid-induced lung injury were randomly assigned into two groups(A and B). Group A served as control, undergoing mechanical ventilation only. Group B received HVHF and mechanical ventilation. Hemodynamic and respiratory mechanic variables were measured before and 0 mm, 120 mm, 240 mm after the induction of lung injury in both groups. Blood and ultrafiltrate samples were collected at the same time points. Plasma and ultrafiltrate concentrations of IL-? were measured by EUSA. Results There were significant differences between two groups on hemodynamic values for mean pulmonary arterial pressure(mPAP), pulmonary artery wedge pressure(PAWP), pulmonary vascular resistance(PVR) and mean arterial pressure(mABP) (P
