Unpredictable Injectate Spread of the Erector Spinae Plane Block in Human Cadavers.
We performed bilateral ultrasound-guided erector spinae plane blocks at the second and eighth thoracic vertebrae in 11 fresh frozen cadavers. Methylene blue dye spread variably and extensively deep to the erector spinae muscles fascia with involvement of the spinal rami and paravertebral space in 1 of 11 cadavers when injected at the eighth thoracic vertebra, and in 4 of 11 cadavers at the second thoracic vertebra, with crossover to the contralateral side of the spine. Our study demonstrates that in cadavers, an erector spinae plane block follows the fascial planes with unpredictable spread, which might explain its varying clinical efficacy.

Pharmacological Characters of Oliceridine, a μ-Opioid Receptor G-Protein[FIGURE DASH]Biased Ligand in Mice.
A major advancement in the field of analgesic pharmacology has been the development of G-protein-biased opioid agonists that display less respiratory depression than conventional drugs. It is uncertain, however, whether these new drugs cause less tolerance, hyperalgesia, and other maladaptations when administered repeatedly. ⋯ Aside from reduced respiratory depression, G-protein-biased agonists such as oliceridine may reduce opioid maladaptations and enhance the quality of surgical recovery.

Special Report From the Society for the Advancement of Blood Management: The Choosing Wisely Campaign.
Over 7 years ago, the American Board of Internal Medicine Foundation (ABIM) created the national Choosing Wisely campaign with the purpose of encouraging active dialogue between health care providers and patients, focusing on appropriateness, quality care, and resource management. This special communication from the Society for the Advancement of Blood Management (SABM) serves to highlight the society's recent participation in the Choosing Wisely campaign, encouraging sensible dialogue between clinicians and our patients with the intent to promote patient-centered, evidence-based care. The article addresses the rationale and supportive data for the 5 SABM Choosing Wisely recommendations.

Anesthetic Management of Patients After Traumatic Injury With Resuscitative Endovascular Balloon Occlusion of the Aorta.
Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a temporizing maneuver for noncompressible torso hemorrhage. To our knowledge, this single-center brief report provides the most extensive anesthetic data published to date on patients who received REBOA. ⋯ All patients received blood products during their index operations and received less inhaled anesthetic gas than normally required for healthy patients of the same age. This study serves as an important starting point for clinician education and research into anesthetic management of patients undergoing REBOA.

A Preoperative Cognitive Screening Test Predicts Increased Length of Stay in a Frail Population: A Retrospective Case-Control Study.
Frailty is associated with adverse perioperative outcomes including major morbidity, mortality, and increased length of stay. We sought to elucidate the role that a preoperatively assessed Mini-Cog can play in assessing the risk of adverse perioperative outcomes in a population at high risk of frailty. ⋯ In a high-risk pool of patients, Mini-Cog may not be sensitive enough to detect significant differences for most adverse outcomes. Further work is needed to assess whether cognitive screens with greater resolution are of value in this context and to compare tools for assessing overall frailty status.
