Dexmedetomidine and midazolam usage and association with BSRI scores in preterm infants with chronic respiratory failure.
Article in Journal of perinatology : official journal of the California Perinatal Association, 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
objectiveTo quantify midazolam (MID) and dexmedetomidine (DEX) exposure in preterm infants with chronic respiratory failure (CRF) due to severe bronchopulmonary dysplasia (sBPD) and assess associations with Behavioral Signs of Respiratory Instability (BSRI) scores. STUDY
designInfants born <32 weeks' gestation with sBPD requiring tracheostomy and chronic ventilation were included. Daily MID and DEX exposure was quantified from NICU admission until discharge, death, or transfer. Multivariable mixed-effects models evaluated associations between medication exposure and weekly BSRI scores, adjusting for selected confounders.
resultsAmong 40 infants (median NICU stay: 202 days), median exposures were 4.4 weeks for DEX and 2 weeks for MID, with peak doses surrounding tracheostomy. Medication exposure was not independently associated with BSRI scores. Higher respiratory severity scores correlated with increased medication doses.
conclusionNeurosedative medication dosing correlated with disease severity. These findings highlight the need to optimize dosing strategies and neurodevelopmental outcomes in this vulnerable population.
