Clinical evaluation of a new chest tube used in neonates.

We report preliminary experience with a newly designed chest tube (JCT), for evacuation of neonatal pneumothorax. The catheter has a unique pigtail confirguration at the distal end, intended to simplify placement and minimize chest wall and lung trauma by reduced tube size and depth and insertion. Thirty-eight JCTs were placed in neonates with pneumothoraces. Neonates' birth weights ranged from 400 to 3,595 grams. All 38 tubes immediately relieved clinical signs of pneumothoraces. Thirty-five (92%) tubes immediately fully evacuated the pneumothoraces as evidences on chest radiograph. Twelve pneumothoraces partially reoccurred at a mean of 24 hours following JCT placement. These tubes were either irrigated or replaced. This newly configured chest tube functions effectively in the treatment of neonatal pneumothorax.
