Effects of the First Spontaneous Breathing Trial in Children With Tracheostomy and Long-Term Mechanical Ventilation.
Observational study in Respiratory care, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundWeaning and liberation from mechanical ventilation in pediatric patients with tracheostomy and long-term mechanical ventilation constitute a challenging process due to diagnosis heterogeneity and significant variability in the clinical condition. We aimed to evaluate the physiological response during the first attempt of a spontaneous breathing trial (SBT) and to compare variables in subjects who failed or passed the SBT.
methodsThis was a prospective observational study in tracheostomized children with long-term mechanical ventilation admitted to the Hospital Josefina Martinez, Santiago, Chile, between 2014-2020. Cardiorespiratory variables such as breathing pattern, use of accessory respiratory muscles, heart rate, breathing frequency, and oxygen saturation were registered at baseline and throughout a 2-h SBT with or without positive pressure depending on an SBT protocol. Comparison of demographic and ventilatory variables between groups (SBT failure and success) was performed.
resultsA total of 48 subjects were analyzed (median [IQR] age of 20.5 [17.0-35.0] months, 60% male). Chronic lung disease was the primary diagnosis in 60% of subjects. Eleven (23%) total subjects failed the SBT (< 2 h), with an average failure time of 69 ± 29 min. Subjects who failed the SBT had a significantly higher breathing frequency, heart rate, and end-tidal CO
conclusionsConducting an SBT to evaluate the tolerance and cardiorespiratory response in tracheostomized children with long-term mechanical ventilation is feasible. Time on mechanical ventilation before the first attempt and type of SBT (with or without positive pressure) could be associated with SBT failure.
