Liposomal Bupivacaine’s Plausibility Fails to Translate

Author: Michael R. Fettiplace, M.D., Ph.D. Anesthesiology May 2024, Vol. 140, 868–870. “[As] evidence accumulates, we find that the biologic plausibility of liposomal bupivacaine does not translate into clinical relevance.” For over a century, anesthesiologists have sought to extend the utility, duration, and safety of local anesthetics, from the original topical instillation of cocaine onto the […]

Topographical Features of Pediatric Electroencephalography during High Initial Concentration Sevoflurane for Inhalational Induction of Anesthesia

Authors: Jessica C. Martin, Ph.D., B.Sc. (Hons.), B.Eng et al  Anesthesiology May 2024, Vol. 140, 890–905. Background High-density electroencephalographic (EEG) monitoring remains underutilized in clinical anesthesia, despite its obvious utility in unraveling the profound physiologic impact of these agents on central nervous system functioning. In school-aged children, the routine practice of rapid induction with high concentrations […]

Thermodilution-derived Recirculation and Cardiac Output Measurement during Veno-venous Extracorporeal Membrane Oxygenation

Authors: Michael Mazzeffi, M.D., M.P.H., M.Sc., F.A.S.A.; Jacob Gutsche, M.D. Anesthesiology May 2024, Vol. 140, 887–889. “Cardiac output cannot be accurately measured during veno-venous ECMO using traditional pulmonary artery catheter thermodilution because recirculation in the ECMO circuit tends to overestimate true cardiac output.” Veno-venous extracorporeal membrane oxygenation (ECMO) has become a widely accepted therapy for adults with […]

Analgesic Effectiveness of Liposomal Bupivacaine versus Plain Local Anesthetics for Abdominal Fascial Plane Blocks

Authors: Nasir Hussain, M.D., M.Sc. et al  Anesthesiology May 2024, Vol. 140, 906–919. Background Liposomal bupivacaine is reported to prolong the duration of analgesia when used for abdominal fascial plane blocks compared to plain local anesthetics; however, evidence from randomized trials is mixed. This meta-analysis aims to compare the analgesic effectiveness of liposomal bupivacaine to plain […]

Postpartum Guillain-Barré Syndrome

Authors: Chen M et al Cureus 16(2): e55207. doi:10.7759/cureus.55207 Abstract Guillain-Barré syndrome (GBS) is a rare acute-onset neurological disease with significant morbidity and mortality. The risk of GBS increases after delivery. Labor and delivery presents many possible risk factors for GBS. However, risk factors and prognosis of postpartum GBS remain unclear due to its low incidence. Here, […]
