Background: Pleural effusion is a common medical problem existing all over the world, especially in developing countries. Pleural effusion of tuberculous origin is very common in India. The effect of pleural effusion depends on the cause and the amount of fluid in pleural space. This study aims to assess the tamponade physiology occurring in cases of large pleural effusion even in absence of any pericardial effusion and treatment of this condition should be thoracocentesis rather than pericardiocentesis. Material and Methods: This cross-sectional study was done at VAMCRH, Banthra, Shahjahanpur, U.P. from February 2020 to October 2021. 73 patients were randomly selected from patients presented with large pleural effusion in medical emergency and medical ward. Detail history and clinical examination were done immediately. All patient with large pleural effusion whether unilateral or bilateral were enrolled in this study, while patients with pleural effusion of cardiac etiology, pericardial effusion and terminally ill were 11 cases excluded from this study. So total 62 cases included in this study. Results: Sixty two cases of large pleural effusion were selected randomly irrespective of age, sex, etiology or sidedness of pleural effusion and were enrolled in this study group. General clinical parameters like pulse rate, respiratory rate, blood pressure etc. were measured. All sixty two patients with large pleural effusion were evaluated with echocardiography and echocardiographic parameters like chamber size of heart, Right ventricular diastolic collapse, right atrial diastolic cpllapse and respiratory flow variation across Mitral, Tricuspid, Pulmonary and Aortic valve were noted. Then 1000 to 1500 ml of pleural fluid were removed by thoracocentesis and a check x-ray was again repeated to make sure that pleural effusion remain below half of total lung field.A repeat echocardiography was done within 24 hour of thoracocentesis of large pleural effusion. Echocardiographic parameters like chamber size of heart, right ventricular diastolic collapse , right atrial diastolic collapse and respiratory flow variation across Mitral, Tricuspid, Pulmonary and Aortic valve were noted again. All the data were collected and kept for final study and were statistically analysed. The result of present study was to assess the effect of large pleural effusion on cardiovascular haemodynamics by means of echocardiography. Conclusion: Patient’s with tamponade physiology who has both large pleural effusion and pericardial effusion a pleurodesis is probably the safest initial procedure and might result in complete recovery from tamponade physiology.
