The Effect of Dexmedetomidine Sedation on Lower Gastrointestinal Motility in Children-Is It Suitable for Anorectal Manometry?
Article in Journal of clinical medicine, 2023. 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
Anorectal manometry is one of the most frequently performed gastrointestinal motility studies in children. It is an important study in diagnosing Hirschsprung disease (HD). These procedures can be uncomfortable, painful and emotionally distressing. Nitrous oxide or midazolam are the only pharmacologic options available, as clinical experience suggests that they do not alter manometry readings. Our study was designed to determine whether Dexmedetomidine (DEX) could provide adequate sedation without disrupting anal and rectal pressure. The effect of DEX on anorectal function has never been studied in children. This prospective study recorded anorectal manometry (ARM) measurements prior to the administration of DEX and then repeated the measurements at 1 and 5 min after DEX. The main ARM measurements included resting intra-anal sphincter pressure (IASP) and the presence and characteristics of the recto-anal inhibitory reflex (RAIR). DEX was administered as a bolus followed by a continuous infusion. Twenty patients were included (60% female; mean age 10.8 ± 4.6 years). The RAIR became absent in 2/16 (12.5%) patients after DEX administration. DEX may alter physiologic ARM and IASP recordings necessary to diagnose gastrointestinal medical conditions.
