Can spontaneous pneumothorax patients be treated by ambulatory care management?
OBJECTIVE: In the Emergency Department, it would be worthwhile to treat pneumothorax patients on an outpatient basis by utilizing a small-calibre catheter and Heimlich valve insertion. We evaluated this treatment and compared it with the closed thoracostomy. METHODS: In this comparative study, the success rate, complications and recurrence rate of treating spontaneous pneumothorax patients by using a small-calibre catheter and Heimlch valve were compared with those of a similar-sized group treated by closed thoracostomy. RESULTS: Pneumothorax was successfully treated on an ambulatory basis by using the small-calibre catheter and Heimlch valve in 20 patients (47%); this was less than the 42 patients (89%) who were successfully treated by closed thoracostomy. While no complications were encountered in the group treated using the small-calibre catheter and Heimlich valve, 11 patients in the group treated by closed thoracostomy developed complications.
