Flexible Bronchoscopy in Neonates With Congenital Diaphragmatic Hernia.
Article in Pediatric pulmonology, 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
backgroundFlexible bronchoscopy (FB) may facilitate ECMO and ventilator weaning through diagnosing airway anomalies and removal of mucous plugs in the critically-ill pediatric population. Only few studies on FB in critically-ill neonates exist, and even fewer focus on neonates with congenital diaphragmatic hernia (CDH) requiring extracorporal membrane oxygenation (ECMO). This study aims to evaluate the risk and benefit of FB in infants with CDH.
methodsA retrospective review of CDH infants treated at a specialized single center between October 2019 and August 2024 was conducted. Baseline characteristics were compared between patients with and without FB. Procedural indications, findings and complications were analyzed.
resultsA total of 142 newborns were analyzed. Infants requiring FB (n = 29, 20.4%) exhibited an overall higher disease burden (lower observed-to-expected lung-to-head ratio [p < 0.001), liver herniation (p = 0.002), ECMO (p < 0.001), defect size (p = 0.042), congenital anomalies (p = 0.019), heart defects (p = 0.010)]. The primary indications for the total 56 FBs were prolonged weaning and pulmonary hemorrhage. The most common complication was self-resolved hypoxemia (16.1%). Bronchial casts were found in 31.6%. Tracheo-/bronchomalacia was diagnosed in 16 infants (55.2%). Postprocedural chest Xrays were mostly unchanged (61.9%). A trend to achieve higher tidal volumes post-FB (p = 0.090) with similar peak inspiratory pressures (p = 0.917) was noted.
conclusionsIn critically-ill neonates with CDH, FB was safe, with a high diagnostic and potential therapeutic yield. The necessity for FB may be an additional indicator of CDH disease severity. Further research is needed to establish uniform assessment metrics and explore other modalities such as electrical impedance tomography or lung ultrasound in the context of FB.
