Abstract:
Objective:To assess the value of critical care ultrasonography in the diagnosis of the etiology of hyoxemia after cardiac surgery .Methods:Sixty-eight patients with hypoxemia who underwent cardiac surgery from August 2015 to January 2016 in Zhongshan Hospital , Fudan University were included in the study . Then , after the primary clinical assessment ,point-of-care ultrasonography of the heart and lungs was done by ICU doctors with experience in critical care ultrasonography (critical care ultrasonography group) .The final diagnosis results were matched ,and the performance of critical care ultrasonography was compared and analyzed .Results:In the final diagnosis of 68 cases ,there were 6 cases of pneumothorax ,24 cases of pulmonary edema ,12 cases of pulmonary consolidation and 14 cases of pleural effusion . The sensitivity and specificity of routine examination and critical care ultrasonography for the diagnosis of pneumothorax were 50 .0% vs 85 .7% and 98 .4% vs 98 .4% ;pulmonary edema 75 .0% vs 83 .3% and 79 .5% vs 86 .4% ;pulmonary consolidation 50 .0% vs 83 .3% and 91 .1% vs 96 .4% ;pleural effusion 57 .1% vs 100% and 88 .9% vs 100% .Conclusions:This study suggested that critical care ultrasonography has relatively higher sensitivity and specificity for pneumothorax , pulmonary edema ,consolidation and pleural effusion compared with routine clinical examination .The use of critical care ultrasonography appears to be an attractive complementary diagnostic tool to clarify the cause of hypoxemia and seems able to contribute to an early therapeutic decision .
