title: Catheter aspiration for simple pneumothorax (CASP) in the outpatient management of simple traumatic pneumothorax.
abstract: Catheter aspiration for simple pneumothorax (CASP) was evaluated prospectively in the outpatient management of simple traumatic pneumothorax in 17 patients and compared to conventional tube thoracostomy (CTT) in 17 matched control patients. In 16 of the 17 consecutive study patients CASP maintained lung reexpansion without complications. Pneumothorax was due to needle puncture for drug abuse in 11 patients, stab wounds in five patients, and blunt trauma in one patient. The CASP patients were not hospitalized, whereas the control CTT patients averaged 4.9 days' hospitalization. CTT was associated with complications in two patients versus none for CASP. Parenteral analgesics were utilized for greater than 48 hours in CTT patients but were not needed for CASP patients. Costs averaged +310 for CASP compared to +3,030 for CTT. This ongoing pilot study data indicates that CASP is a reasonable alternative to CTT in selected patients with simple traumatic pneumothorax.
