Lung protection by pulmonary perfusion with oxygenated blood in children with congenital heart defects / 中华胸心血管外科杂志

ABSTRACT

Objective To evaluate the effects of continuous pulmonary artery Perfusion with hypothermic oxygenated blood on lung function in children with congenital heart defects (CHD) and pulmonary hypertension(PH). Methods 20 patients diagnosed with CHD and PH were divided into group 1( perfused with oxygenated blood) and group 2 (conventional CPB). A canula was inserted into the main pulmonary artery for the perfusion with a rate of 15～30 ml?kg -1 ?min -1 . CPB was established as usual. The data of two groups including the oxygen concentration, airway pressure, blood gas analysis were recorded. At fixed times, blood sample was taken out for the measurement of the sICAM-1 and MDA. Results The concentration of sICAM-1 and MDA in group 1 was much lower than that in group 2 on 12 and 24 hours after surgery. Issues of the lung function including OI?A-aDOa_2 and airway pressure was significantly different between the two groups. Conclusion The study showed that the continuous pulmonary perfusion with oxygenated blood could preserve lung function in patients with CHD and PH.
