Postoperative chest tube management: Snapshot of German diversity

Abstract

OBJECTIVES: The management of chest tubes is one of the most critical aspects in patient care in thoracic surgery, and no consensus exists regarding the ideal chest tube management strategy.METHODS: Chest tube management protocols and their effects on chest tube therapy were compared at four German specialist thoracic surgery units. Altogether, 79 patients were stratified for underlying disease and type of surgery. A digital chest drainage system was applied to objectify the presence of air leakages.RESULTS: In our analysis, the average length of drainage therapy was 4.9 ± 2.8 days. Different chest tube management protocols resulted in a significant degree of scatter between units (P = 0.0348). Higher arbitrary postoperative suction levels (4 kPa) resulted in earlier chest tube removal than lower suction levels (2 kPa) (4.2 ± 2.4 vs 5.4 ± 3.0 days, P = 0.06). Patient discharge following chest tube removal was delayed on average by 3.2 ± 2.9 days. This delay was not correlated with the previous duration of chest tube therapy (Spearman's ρ=-0.15, P = 0.25) in contrast to the total length of hospital stay (ρ = 0.59, P < 0.001). © 2012 The Author 2012.
