Pericapsular nerve group block: a 3D CT scan imaging study to determine the spread of injectate.
Current understanding of the mechanism of action of the pericapsular nerve group (PENG) block is primarily based on cadaver studies. We performed an imaging study in patients undergoing hip surgery to enhance the understanding of the analgesic mechanisms following a PENG block. ⋯ Our study suggests that the analgesic effect of the PENG block may be related to the block of the branches of the femoral nerve traveling within the iliopsoas muscle without a spread pattern commensurate with the block of the obturator nerve.

Subpectineal obturator nerve block reduces opioid consumption after hip arthroscopy: a triple-blind, randomized, placebo-controlled trial.
Hip arthroscopy causes severe pain during the first few hours in the postoperative care unit. This is probably due to the intraoperative stretching of the hip joint capsule. Pain relief requires high doses of opioids which may prolong recovery and may cause opioid-related adverse events.The majority of hip joint capsule nociceptors are located anteriorly. The obturator nerve innervates the anteromedial part of the hip joint capsule. We hypothesized that a subpectineal obturator nerve block using 15 ml bupivacaine 5 mg/mL with added epinephrine 5 μg/mL would reduce the opioid consumption after hip arthroscopy. ⋯ We found a significant reduction in the opioid consumption for patients receiving an active subpectineal obturator nerve block. The postoperative intravenous morphine equivalent reduction the first painful 3 hours was reduced by 40% for patients receiving a subpectineal obturator nerve block in this randomized, triple-blind trial.

Narrative reviews in anesthesia and pain medicine: guidelines for producers, reviewers and consumers.
Well-established guidelines and checklists for authors, reviewers, and readers of systematic reviews and scoping reviews are readily available. However, the availability of such for narrative reviews is lacking, including, but not limited to, field-specific guidelines in the field of anesthesia and pain medicine. ⋯ We include a recommended checklist that will aid producers, editors, reviewers, and consumers of narrative reviews as well as examples specific to the field of anesthesia and pain medicine. It is the hope that the guidelines recommended here will aid producers, editors, reviewers, and consumers of narrative reviews in anesthesia and pain medicine, including Regional Anesthesia & Pain Medicine Adherence to such should help differentiate between narrative reviews and other types of reviews as well as provide consistency in what elements are necessary to include in a narrative review in the field of anesthesia and pain medicine.
