Pediatric Charcot-Marie-Tooth disease and peripheral nerve blocks: a retrospective cohort study of 25 patients.
Article in Canadian journal of anaesthesia = Journal canadien d'anesthesie, 2024. 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
purposeCharcot-Marie-Tooth (CMT) disease is an inherited neurologic disorder characterized by progressive peripheral neuropathies. The use of peripheral nerve blocks (PNB) in patients with CMT disease has been controversial because of concerns about exacerbating existing neurologic impairments and the "double hit" hypothesis. We aimed to assess the use of PNB in pediatric patients with CMT disease undergoing orthopedic surgery to address the limited data available in the literature on this topic.
methodsIn this retrospective cohort study, we included all pediatric patients with CMT disease scheduled for orthopedic surgery receiving PNB at our centre. All of the patients had preoperative neurologic exams and received one or more ultrasound-guided regional anesthesia techniques. Data extracted included details of anesthesia technique, surgical procedure, opioid consumption, and pain scores during the first three postoperative days. We also reviewed any complications such as neurologic deficits and local anesthetic toxicity. We used descriptive statistics to summarize the findings.
resultsWe included 25 patients, 14 of whom (56%) presented with pre-existing neurologic deficits, primarily in the lower extremities. Postoperative assessments revealed no new neurologic impairments in 24/25 (96%) patients, with only one patient experiencing a nerve injury possibly related to the surgical procedure. Opioid consumption was low in the postanesthesia care unit and on the day of surgery. No additional complications were noted in the first 72 hr after surgery.
conclusionDespite concerns, PNB showed favourable outcomes in a pediatric cohort with CMT disease, with low opioid consumption and pain scores and minimal complications during follow-up. These findings match previous reports of adult patients with CMT disease and suggest that the benefits of PNB may outweigh the perceived risks in pediatric patients with CMT disease.
