Background:
Efficacy of chest radiograph protocol after tube thoracostomy tube (CT) removal.
Methods:
Retrospective review (July of 1995 to July of 1996) of 141 patients with CT followed throughout their hospitalization. Excluded patients died (23 patients) or had thoracotomy (13 patients) before CT removal.
Results:
A total of 105 patients had 113 CT removed (mean age, 36.9 years; Injury Severity Score = 23.4; CT duration, 5.0 days). Protocol chest radiographs were performed on average at 7.9 and 22.1 hours. Recurrent pneumothorax (RHPTX = new interpleural air) occurring in 12 patients (11%) and persistent pneumothorax (PHPTX = same volume of interpleural air) occurring in 13 patients (12%) caused no clinical problems and were treated without tube replacement. Three patients had symptoms after removal; none had RHPTX. Two patients had clinical signs; one reaccumulated a hemothorax requiring CT replacement, the other improved without replacement.
Conclusions:
Clinically significant RHPTX/PHPTX after CT removal is infrequent. Signs not symptoms detect CT removal complications. At our institution, chest radiographs are obtained in a delayed manner from protocol and offer no benefit over clinical assessment.
