Caudal block, high flow oxygen insufflation and dexmedetomidine sedation for inguinal hernia surgery in infants-A prospective evaluation of an alternative anesthesia technique.
Trial report in Paediatric anaesthesia, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundInguinal hernia repair is the most common operation in infants, with well recognized anesthetic and perioperative risks. The aim was to investigate if the combination of caudal block, high-flow nasal oxygen insufflation and intravenous dexmedetomidine sedation is suitable for infants undergoing inguinal hernia surgery.
methodsA prospective multicenter international study was performed in three centers in Australia and New Zealand. Fifty infants less than 64 weeks post-menstrual age undergoing inguinal hernia surgery were enrolled. Exclusion criteria were any condition that contraindicated the use of the anesthesia technique. The technique included intravenous dexmedetomidine with a loading dose of 1-2 mcg/kg over 10 min and maintenance of 0.2-3 mcg/kg/h, high-flow nasal oxygen insufflation 2 L/kg/min with an oxygen blender, and a caudal block using 1 mL/kg 0.2% ropivacaine. The primary outcome was the successful completion of surgery without conversion to general anesthesia.
resultsCompletion of surgery with the technique was successful in 41/50 (82%) infants. Care was provided by 22 anesthesiologists and 11 surgeons. Infants had a low incidence of intraoperative complications, including apnea [1 (2.4%)], bradycardia [2 (4.9%)], hypotension [2 (4.9%)], and desaturation [1 (2.4%)]. Postoperative complications included apnea [3 (7.3%)], bradycardia [3 (7.3%)], hypotension [3 (7.3%)], desaturation [4 (9.8%)]. No infants were intubated in the first 24 h postoperatively.
conclusionCaudal block, high-flow nasal oxygen insufflation and intravenous dexmedetomidine sedation is a potential alternative to general anesthesia for infant inguinal hernia surgery with a low rate of complications in this small cohort of infants.
