The Influence of Vasopressor-Induced Arterial Blood Pressure Elevation on Muscle-Recorded Motor Evoked Potentials

Authors: Dulfer SE, et al. Anesthesia & Analgesia. September 05, 2025. doi:10.1213/ANE.0000000000007701 This prospective observational study investigated how blood pressure elevation with norepinephrine and ephedrine affects transcranial electrical stimulation muscle-recorded motor evoked potentials (Tc-mMEPs) in patients undergoing spinal surgery. False positive Tc-mMEP warnings are common during intraoperative monitoring, often attributed to low blood pressure, leading […]

Acute Pain After Total Knee Arthroplasty: 2-Arachidonoylglycerol Tone and Endocannabinoid/Eicosanoid Crosstalk

Authors: Schutz L et al Anesthesia & Analgesia. September 09, 2025. doi:10.1213/ANE.0000000000007741 This prospective study investigated whether intraoperative levels of the endocannabinoid 2-arachidonoylglycerol (2-AG) are associated with acute postoperative pain after total knee arthroplasty (TKA). Ninety patients were enrolled, and 2-AG levels were measured in synovial fluid (SF) and cerebrospinal fluid (CSF). Higher SF 2-AG […]
