Abstract:
Objective To study the role of sodium nitroprusside in preventing pulmonary ische-mia-reperfusion injury and the possible mechanism. Methods Fourteen pigs were randomly divided into 2 groups: control group underwent controlled reperfusion with reperfusion solution (leukocyte-depleting blood modified buckberg perfusate = 4:1) for 10 min at lower pressure of 18 mm Hg and 37℃? 1℃ before removing the pulmonary artery clamp; experimental group were subjected to controlled reperfusion with reperfusion solution before removing the pulmonary artery clamp, followed by infusion of sodium nitroprusside (10?g?kg-1?min 1 for 10 min) via pulmonary artery. Blood oxygen pressure, pulmonary vascular resistance, pulmonary compliance and the changes in pulmonary oxygen-ation function were assessed 0. 5, 1 and 2 h later. After the trail, the contents of water, NO and MDA in pulmonary tissues were measured. Results In the experimental group, left lung oxygenation function and pulmonary compliance was significantly better (P
