Hypothermic ventricular fibrillation with left ventricular drainage under cardiopulmonary bypass on canine lung preservation without aortic-cross clamping / 中国病理生理杂志

ABSTRACT

AIM:To evaluate the protective effect of hypothermic ventricular fibrillation without aortic-cross clamping under cardiopulmonary bypass(CPB)on canine lung.METHODS:Fourteen dogs were randomly divided into two groups.All dogs received a standardized anesthetic technique.A conditional CPB was performed in every instance.Ventricular fibrillation was induced by systemic hypothermia to 28 ℃ and pericardial cooling saline in the experimental group.A standard CPB was performed in control group.The concentration of IL-8 in serum was measured by ELISA.The expressions of NF-?B and ICAM-1 were determined by using immunohistochemical staining.RESULTS:Serum IL-8 level in experimental group was significantly lower than that in control group(P
