[Out-of-hospital cardiac arrests : year 2023 review of the CHC - Bcar registry in Liege area (Belgium)].

Out-of-hospital cardiac arrests represent impactful events. Despite the evolution of care, they are still associated with high morbidity and mortality. We present the analysis of our activity included in the 2023 CHC - Bcar registry in Liege area (Belgium).

Obturator canal block: an anatomical study.

Background: Different approaches to the obturator nerve have been described. However, few have focused on the injection point inferior the iliopubic ramus, specifically at the exit of the obturator canal. This study aims to anatomically evaluate the ultrasound-guided obturator nerve block at the exit of the obturator canal, detailing anatomical landmarks and solution distribution.

[Post-traumatic stroke due to fat embolism].

Fat embolism syndrome mainly occurs following trauma to the long bones or pelvis. Non-traumatic causes are rarer. Its incidence varies greatly and depends on the number of fractures involved.

Comparative anatomical study of digital block with the WALANT, interdigital, and transthecal techniques.

Introduction: Interdigital block and transthecal block through the flexor sheath are commonly used techniques for the anesthesia of isolated fingers. The wide-awake local anesthetic no-tourniquet technique is a relatively new approach for local anesthesia during finger procedures. The anatomical spread of local anesthetics with the wide-awake local anesthetic no tourniquet technique has not been described adequately.

No evidence of fascicular injury following a low-volume intraneural injection of the median nerve: a cadaveric study.

Background: The test dose or hydrolocation technique allows rapid detection of spread location. Though its primary aim is to enhance safety in peripheral nerve blocks, evidence on the potential risks of an intraneural test aliquot is lacking. We conducted a cadaveric study to evaluate the risk of fascicular injury following a low-volume (<1 mL) intraneural injection of the median nerve.

Intravenous lipid emulsion for a life-threatening prothipendyl intoxication.

Prothipendyl, a lipophilic neuroleptic drug, requires a careful dosage regimen due to its potential side effects, including life-threatening arrhythmias.This report outlines a case of severe prothipendyl intoxication, its management and the successful utilisation of Intralipid, an intravenous lipid emulsion, in treating ventricular arrhythmia postmassive prothipendyl ingestion. Additionally, the mechanism of action of Intralipid and the rebound concentration of the lipophilic drug in such scenarios are discussed.

Non-Neurological Complications after Mechanical Thrombectomy for Acute Ischemic Stroke: A Retrospective Single-Center Study.

Introduction: The global burden of stroke is high and mechanical thrombectomy is the cornerstone of the treatment. Incidences of acute non-neurological-complications are poorly described. Improve knowledge about these complications may allow to better prevent, detect and/or manage them.

Ultrasound is better than injection pressure monitoring detecting the low-volume intraneural injection.

Introduction: Inadvertent intraneural injection is not infrequent during peripheral nerve blocks. For this reason, injection pressure monitoring has been suggested as a safeguard method that warns the clinician of a potentially hazardous needle tip location. However, doubts remain whether it is superior to the sonographic nerve swelling in terms of earlier detection of the intraneural injection.

Characteristics and outcomes of patients undergoing anesthesia while SARS-CoV-2 infected or suspected: a multicenter register of consecutive patients.

Background: There are limited data to detail the perioperative anesthetic management and the incidence of postoperative respiratory complications among patients requiring an anesthetic procedure while being SARS-CoV-2 positive or suspected.

Methods: An observational multicenter cohort study was performed including consecutive patients who were SARS-CoV-2 confirmed or suspected and who underwent scheduled and emergency anesthesia between March 17 and May 26, 2020.

Results: A total of 187 patients underwent anesthesia with SARS-CoV-2 confirmed or suspected, with ultimately 135 (72.

Opening injection pressure monitoring using an in-line device does not prevent intraneural injection in an isolated nerve model.

Background: Injection pressure monitoring using in-line devices is affordable and easy to implement into a regional anesthesia practice. However, solid evidence regarding their performance is lacking. We aimed to evaluate if opening injection pressure (OIP), measured with a disposable in-line pressure monitor, can prevent intraneural (subepineural) injection using 15 pound per square inch (PSI) as the reference safety threshold.

Interfascial Spread of Injectate After Adductor Canal Injection in Fresh Human Cadavers.

The adductor canal block has become a common analgesic technique in patients undergoing knee arthroplasty. Dispersion of local anesthetic outside the adductor canal through interfascial layers and blockade of smaller nerves that confer innervation to the knee could contribute to the analgesic efficacy of the adductor canal block. We studied the diffusion of local anesthetic mixed with dye after injection into the adductor canal in fresh human cadavers.
