An analysis and management experience of preoperative hypoxemia in patients with acute Standford type B aortic dissection
Abstract：Objective To investigate the causes and management of preoperative hypoxemia in patients with acute Standford type B aortic dissection .Methods From June 2012 to September 2013 , 139 patients of acute Standford type B aortic dissection were collected and 66 cases of them underwent hypoxemia .The clinic correlated information has been summarized and analyzed retrospectively .We investigated the causes of preoperative hypoxemia and treated the condition accordingly .Results In patients with hypoxemia , all indexes that reflect the inflammation were significantly higher than those in patients without hypoxemia ( P <0.05 ).Of the 66 patients who underwent hypoxemia , 39 cases (59.9%) met the diagnostic standard of acute lung injury (ALI), 58 cases (87.88%) complicated with hydrothorax and 23 cases (34.85%) met the diagnostic standard of systemic inflammatory response syndrome.These patients were treated with drugs that used for proper sedation , improvement of oxygen supply, as well as for stabilization of blood pressure and ventricular rate .Part of the patients underwent elective endovascular graft exclusion .Conclusion The incidence of hypoxemia is high in patients with acute type B aortic dissection .In patients with dissection of aorta , lung injury , hydrothorax and even ARDS followed by excessive inflammation reaction would affect respiratory function and further induce hypoxemia .
