Effect of Therapeutic Thoracocentesis on Short Term Peripheral Oxygen Saturation and other Hemodynamics, in Al-Najaf


AbstractBackground: Pleural effusion often causes abnormal pulmonary gas exchange. Thoracentesis is commonly used to relieve dyspnea in patient with pleural effusion, but its effect upon arterial oxygenation is varied and poorly understood. Aim of study: To determine the effect of therapeutic thoracentesis on arterial O2 saturation and other hemodynamics.Patients and methods: We studied thirty patients (20 men and 10 women) mean age 44.5 year with unilateral pleural effusion of varied causes. The diagnosis of pleural effusion was depend on clinical and radiological bases. Patients with large pleural effusion were included in this study. At the time of investigation, all patients were clinically stable and each patient was informed about the possible side effect of the Procedure .Results: This study reveals that the arterial O2 saturation was significantly decreased after thoracentesis The pulse rate was significantly decreased after thoracentesis . But no significant changes were found in either blood pressure or respiratory rate . Conclusion: There was a significant reduction in arterial O2 saturation after thoracentesis . There was significant reduction in pulse rate after thoracentesis . while there was no change in blood pressure and respiratory rate .
