Risk factors analysis for preoperative hypoxemia in patients with Stanford Type B aortic dissection
Abstract：Objective To investigate the risk factors for hypoxemia in preoperative Stanford Type A aortic dissection.Methods From January 2004 to February 2016,clinical data of 200 consecutive patients with Stanford Type B aortic dissection were retrospectively analyzed.Preoperative hypoxemia was defined as the arterial partial oxygen over inspired oxygen fraction (PaO2/FiO2) more than 200 mm Hg,potential risk factors were screened out by univariate analysis between hypoxemia group and non-hypoxemia group,then independent risk factors were identified by binary logistic regression analysis.The prediction model was established upon acquired independent risk factor.Results 41 case of hypoxemia were induced by preoperative Stanford Type B aortic dissection,incidence of 20.5％.Univarite analysis showed that Left ventricular end systolic diameter,aortic forward velocity,high sensitive C reactive protein (hs-CRP),total protein (TBIL),direct bilirubin (DBIL),indirect bilirubin(IBIL),serum total protein (TP),serum albumin (ALB),serum lactate dehydrogenase (LDH),serum blood platelet count (PLT),whole blood neutrophil percentage (NEUT％) were risk factors for hypoxemia with preoperative Stanford Type B aortic dissection.Binary logistic regression analysis showed TBIL was independent risk factors for hypoxemia in preoperative Stanford Type B aortic dissection (OR=1.038,95％CI 1.003-1.075,P=0.031),TP was protective factors(OR=0.941,95％CI 0.893-0.991,P=0.022).Conclusion There is a high proportion of hypoxemia in preoperative Stanford Type B aortic dissection.TBIL is independent risk factors for hypoxemia in preoperative Stanford Type B aortic dissection,TP indicates as protective factors.
