Ventral Tegmental Area Glutamatergic Neurons Facilitated Emergence From Isoflurane Anesthesia Involves Excitation of Lateral Septum GABA-ergic Neurons in Mice

AUTHORS: Zhang, Simin MD et al  Anesthesia & Analgesia 139(2):p 397-410, August 2024. | BACKGROUND: Ventral tegmental area (VTA) glutamatergic neurons promote wakefulness in the sleep-wake cycle; however, their roles and neural circuit mechanisms during isoflurane (ISO) anesthesia remain unclear. METHODS: Fiber photometry and in vivo electrophysiology were used to observe the changes in neuronal or terminal […]

The association between intraoperative hypotension and postoperative delirium- a retrospective cohort analysis

Authors: Shiri Zarour, MD et al  Anesthesiology July 2024. Background Intraoperative hypotension might contribute to the development of postoperative delirium through inadequate cerebral perfusion. However, evidence regarding the association between intraoperative hypotension and postoperative delirium is equivocal. We therefore tested the hypothesis that in patients>70 years having elective non-cardiac surgery, intraoperative hypotension is associated with […]

Endothelium-Derived Extracellular Vesicles Expressing Intercellular Adhesion Molecules Reflect Endothelial Permeability and Sepsis Severity

AUTHORS: Takei, Yusuke MD, PhD et al  Anesthesia & Analgesia 139(2):p 385-396, August 2024. BACKGROUND: Currently, clinical indicators for evaluating endothelial permeability in sepsis are unavailable. Endothelium-derived extracellular vesicles (EDEVs) are emerging as biomarkers of endothelial injury. Platelet endothelial cell adhesion molecule (PECAM) and vascular endothelial (VE)-cadherin are constitutively expressed endothelial intercellular adhesion molecules that regulate […]

Determination of the Optimal Volume of 0.5% Ropivacaine in Single-Injection Retroclavicular Brachial Plexus Block for Arthroscopic Shoulder Surgery

Authors: Hongye Zhang, MD et al  Anesthesiology July 2024. Background A brachial plexus block plays an important role in providing perioperative analgesia for shoulder surgery; however, the inherent risk of phrenic nerve block and resulting hemidiaphragmatic paralysis may limit its use in patients with compromised pulmonary function. This study aimed to evaluate safety, efficacy, the […]

Accuracy and Precision of Three Acceleromyographs, Three Electromyographs, and a Mechanomyograph Measuring the Train-of-four Ratio in the Absence of Neuromuscular Blocking Drugs

Authors: Zain Wedemeyer, B.S. et al  Anesthesiology August 2024, Vol. 141, 262–271. Background The accuracy and precision of currently available, widely used acceleromyograph and electromyograph neuromuscular blockade monitors have not been well studied. In addition, the normalization of the train-of-four ratio from acceleromyography (train-of-four ratio [T4/T1] divided by the baseline train-of-four ratio) has not been validated […]
