Bleeding Complications from Chest Tube Treatment in Patients on Extracorporeal Membrane Oxygenation Support.
Observational study in Interdisciplinary cardiovascular and thoracic surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesBleeding is a common complication of extracorporeal membrane oxygenation (ECMO) support. While chest tube treatment is infrequently linked to bleeding in non-ECMO patients, several reports suggest a markedly increased risk during ECMO support, sometimes requiring surgical intervention. The true incidence, contributing factors, and effect on outcome from chest tube related bleeding in ECMO patients is unknown.
methodsThis was a single-centre observational study conducted between 2010 and 2024, including both paediatric and adult patients treated with chest tube for pneumothorax or non-haemorrhagic pleural fluid during their ECMO treatment. Major bleeding was defined by chest tube output amount adjusted to patient age, need for multiple red blood cell transfusions, or need for surgical intervention.
resultsOf the 1158 screened ECMO patients, 168 (14.5%) required chest drainage for pleural effusions or pneumothorax during the study period, and a total of 279 chest tubes were analysed. Major bleeding occurred in 21 patients (12.5%) and from 23 chest tubes (8.1%). Fourteen patients required thoracotomy. Bleeding was more common with tubes placed during ECMO support (11.3%) compared to pre-ECMO (4.7%, P = .036). Affected patients had longer ECMO durations (median 42 vs 17 days, P = .003) and lower hospital survival (47.6% vs 71.4%, P = .043). No associations were observed between bleeding and tube size, laterality, type, insertion technique, or ECMO mode. The chest wall was the most commonly identified bleeding location.
conclusionsThere was a markedly increased risk of major bleeding from chest tubes during ECMO, particularly when inserted after cannulation. Patients who experienced bleeding complications had longer hospital stays and lower survival.
