Postsurgical pleurodesis with autologous blood in patients with persistent air leak.
BACKGROUND
Persistent air leak after operation on the lung is one of the most common problems encountered by thoracic surgeons. We present 6 patients who underwent pleurodesis with autologous blood for persistent air leak after operation.


METHODS
Between June 1993 and January 1998, pleurodesis with autologous blood was performed in 6 patients who had air leak of more than 10 days' duration after operation for non-small cell lung cancer. A sample of peripheral blood was taken from the patient's arm and immediately introduced into the chest tube with no additives. The chest tube was left unclamped and off suction, connected to the waterseal drainage, and kept 60 cm above the patient's chest. The next day, the waterseal and chest roentgenogram were reviewed before the chest tube was removed.


RESULTS
A persistent air leak with a mean duration of 16.7 days was observed after the initial operation. Fifty to 250 mL of blood was introduced one time into the chest tube. No patient experienced pain, respiratory difficulty, fever, or episodes of coughing during the procedure. After 24 hours, no air leak was detected in the waterseal drainage in any patient.


CONCLUSIONS
On the basis of these preliminary findings, we believe pleurodesis with autologous blood is a safe and effective method for treating persistent air leak after a thoracic surgical procedure.
