title: Pneumonia with pleural effusions.
abstract: One hundred and forty three among five hundred and twenty-six cases of bacterial pneumonia in adults (27.2%) who had pleural effusion (parapneumonic effusion) admitted to Chulalongkorn Hospital during the period January 1987 to December 1991 were analyzed. There were 40 cases with effusion that was less than 10 mm thick on chest decubitus film, 44 cases of uncomplicated exudative phase, 40 cases of complicated exudative phase (early empyema) and 19 cases of empyema. Most patients in our study required thoracocentesis (72%), had early empyema and emyema (41.3%) as well as high incidence of positive organisms on Gram stain in pleural fluid. This indicates that our patients may have had a prolonged clinical course before coming to the hospital. About half of our patients had pleuitic chest pain or signs of pleural effusion. Among the various stages of parapneumonic effusion, the empyema group had the most delayed response to treatment and needed intercostal drainage for twice the duration of the early empyema group (15.69 vs 7.55 days). The overall mortality was 22.4 per cent. Factors associated with death were advanced age, hospital acquired and broncho-pneumonia, abnormal host, no pleuritic chest pain, no signs of consolidation, respiratory failure, shock and complications of assisted ventilation.
