Prolonged chest tube duration is less well studied in patients with
pneumothorax. We investigated the impact of prolonged chest tube
duration on patient outcomes and the risk factors associated with
prolonged chest tube duration.
This retrospective observational study included 69 subjects who had
been treated with chest tube duration for pneumothorax between 2008 and
2015 at Charles Nicolle teaching Hospital. Clinical, demographic data
and outcomes were collected and analyzed. The subjects were divided
into a prolonged chest tube duration group (> 10 d) and a
non-prolonged group (≤ 10 d).
Mean period of chest tube drainage was 9.84 ? 4.35 days, 25%
of subjects had prolonged chest tube duration. Compared with
non-prolonged group, patients with prolonged chest tube duration group
were older (58.38 versus 35.73, p=0.001). Subjects with prolonged chest
tube duration were significantly associated with comorbidities (62.5%
vs 33.33%; p=0.04), existence of cough (68.75% vs 29.16%; p = 0.005),
fever (25% vs 6.25%; p=0.037), Small chest tubes drainage (46.8% vs
18.75; p=0.048), more complications (31.25% vs 2%; p=0.003), a higher
number of unresolved pneumothorax (31.25% vs 6.25%; p=0.009) and a
longer hospitalization (18.25 days vs 8.44 days; p=0.001).
Through this study, we could find several predictors of prolonged chest
tube duration, and the negative impact on clinical outcomes of these
patients. These findings may improve chest tube management.
