The clinician's perspective on parapneumonic effusions and empyema.

Respondents at an interactive symposium on pleural space infections (n = 339) at the 1991 American College of Chest Physicians Annual Scientific Assembly recorded their personal management preferences for hypothetical patients with empyema. The group's preference was to treat pleural sepsis from an anaerobic multiloculated empyema by pleural decortication (49 percent); however, open thoracotomy with directed chest tube placement (22 percent), chest tube placement with intrapleural streptokinase (14 percent), placement of a single chest tube into the largest pleural loculus (8 percent), and placement of multiple small-bore catheters with computed tomographic guidance (7 percent) all had proponents. In the case of a multiloculated empyema not completely drained by a first chest tube in a nontoxic patient, the preference was drainage by a second chest tube, either a small-bore (42 percent) or a large-bore (36 percent) tube. The heterogeneity of responses suggests that prospective trials comparing treatment modalities are needed.
