    Abstract:
    Objective:To investigate the causes of barium aspiration,death rate and the cause of death in the upper gastrointestinal examinations,and to help the doctor selecting a reasonable method in upper gastrointestinal tract examination.Method:Two cases in our hospital was reported,and totally 25 patients in 22 articles were obtained in pubmed or google shchoolar form 1989 to 2014.Purpose of radiologic studies of the upper digestive tract,distribution of the aspirate,clinical presentation and prognosis after aspiration of the sulfate barium in literature were collected.Result:①Aspiration of barium sulfate mainly happened in elderly patients and infant.The age of died group were older than survive group,however,there were no significant difference statistically(F=0.909, P=0.355).②The directly mortality rate associated with barium aspiration was up to 38.1% in adult,and ten patients of them(47.6%) recovered.All the infants were recovered completely form the respiratory distress cause by the aspiration of barium sulfate.③Aspiration may more likelyoccur in certain conditions involving dysphagia and esophageall obstruction by tumor or foreign body.Further,the gastro-esophageal reflux,recent esophageal surgery,eructation and vomiting may also increase the risk of aspiration of the aspiration of barium sulfate.④About 84.0% patients were with initial dyspnea,hypotension,respiratory distress or respiratory failure.A minority of patients without significant reactions,only suffered fever and cough(16.0%).⑤The deposition of barium sulphate were commonly affected both lungs(80.0%).Barium sulfates distributed in unilateral lung only were found in five patients 20.0%.Conclusion:Aspiration may easier occur in certain conditions involving dysphagia and esophageall obstruction by tumor or foreign body.Further,the gastro-esophageal reflux,recent esophageal surgery,eructation and vomiting may also increase the risk of aspiration of the aspiration of barium sulfate.Most of the patients after aspiration of barium were presented with initial dyspnea,hypotension,respiratory distress or respiratory failure.When considerable amounts of barium sulfate are aspirated into the lung leading to arterial hypoxemia and dyspnea,it is mandatory that aggressive treatment with steroids,antibiotics,respiratory physiotherapy,oxygen,and bronchoalveolar lavage is initiated without delay.
