Weaning outcomes after early vs. late tracheostomy in severe burn injury: a retrospective single-center study.
Article in BMC surgery, 2026. 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
backgroundPatients with severe burn injuries often require prolonged mechanical ventilation (MV). The benefit of an early tracheostomy (ET; ≤ 10 days after injury) to reduce MV duration and facilitate weaning remains unclear. This study aimed to compare weaning outcomes between patients undergoing ET and late tracheostomy (LT; > 10 days after injury) in a high-volume burn center. MATERIALS AND
methodsWe conducted a retrospective analysis of 67 patients admitted to our burn intensive care unit from January 2015 to June 2024. The patients were assigned to two groups based on the timing of the tracheostomy: ET (n = 52) and LT (n = 15). Endpoints of the study were the influence of tracheostomy timing on the time to milestones in the weaning process (CPAP, intermittent breathing without MV, decannulation) and ICU length of stay.
resultsThe mean age was 52.9 (± 19.7) years. The ABSI-scores were similarly distributed, with medians of 9 in the ET group and 8 in the LT group. Inhalation trauma was present in 55.2% of patients across both groups (ET n = 29 (55.8%); LT n = 8 (53.3%)). Regarding weaning milestones, no significant differences were observed in the median time to first intermittent breathing without MV (ET 15 days vs. LT 20 days; p = 0.47) or median time to decannulation (ET 33 days vs. LT 69 days; p = 0.28). However, patients in the ET group reached CPAP significantly earlier than those in the LT group (ET 7 days vs. LT 13 days; p < 0.001). Overall, in-hospital mortality rate was 43.3% (ET 46.2% vs. LT 33.3%; p = 0.38).
conclusionThis study found no substantial benefit associated with early-onset tracheostomy in patients with severe burn injuries. While ET resulted in significantly earlier progression to CPAP-mode, it did not expedite overall weaning success or reduce time to decannulation. While the sample size may limit sensitivity to detect smaller effects, the findings provide insight into weaning dynamics following early versus LT in burn patients. These findings underscore the need for standardized, prospective evaluation in this population.
