Aspiration of pleural fluid with standard techniques is frequently painful for the patient and time-consuming for the physician. The equipment is burdensome in amount, must be cleaned and sterilized after each use, and may contain dangerous air leaks in worn parts and connections.
An advanced method of thoracentesis using equipment which is commercially available is presented in this paper. The few parts required are disposable. Fluid is collected in sterile, closed, graduated containers for measurement and further laboratory studies.
