Abstract:
Objective To investigate the cause of pleural effusion in elderly patients on mechanical ventilation, and to analyze the effect of mechanical ventilation on hemodynamics. Methods 100 elderly patients admitted to our hospital from Jan 2002 to Oct 2004 who had received mechanical ventilation were studied retrospectively and logistic regression analysis of risk factors of pleural effusion before and after mechanical ventilation were performed. 8 patients of them were examined by ultrasonic cardiography before and during mechanical ventilation. Results Before mechanical ventilation there were 27 patients complicated with pleural effusion. After mechanical ventilation another 33 patients were showed to develop pleural effusion. Totally 60 mechanical ventilated patients had pleural effusion. The analysis of logistic regression showed that cardiac insufficiency was significantly correlated with pleural fluid in the patients receiving mechanical ventilation. The transmembrane pressure of tricuspid valve was increased during mechanical ventilation. Conclusion Incidence of pleural effusion increased, hemodynamics changed and the transmembrane pressure of tricuspid valve increased with mechanical ventilation in the elderly patients. Cardiac insufficiency was an important risk factor of pleural effusion.
