Authors: Mathias Maagaard, M.D. et al Anesthesiology June 2024, Vol. 140, 1165–1175. Background Both dexamethasone and dexmedetomidine increase the duration of analgesia of peripheral nerve blocks. The authors hypothesized that combined intravenous dexamethasone and intravenous dexmedetomidine would result in a greater duration of analgesia when compared with intravenous dexamethasone alone and placebo. Methods The authors randomly […]

Background Unfractionated heparin, administered during venoarterial extracorporeal membrane oxygenation to prevent thromboembolic events, largely depends on plasma antithrombin for its antithrombotic effects. Decreased heparin responsiveness seems frequent on extracorporeal membrane oxygenation; however, its association with acquired antithrombin deficiency is poorly understood. The objective […]

Background Dexmedetomidine has repeatedly shown to improve anxiety, but the precise neural mechanisms underlying this effect remain incompletely understood. This study aims to explore the role of corticotropin-releasing hormone–producing hypothalamic paraventricular nucleus (CRHPVN) neurons in mediating the anxiolytic effects of dexmedetomidine. Methods A social […]

Adenomas and serrated polyps are precursors of colorectal cancer, with serrated polyps being more difficult to detect during colonoscopy. The relationship between propofol use and polyp detection remains unclear. The authors investigated the […]

Figure 1, B and C correspond to a healthy 2-yr-old boy who underwent hypospadias repair during general anesthesia combined with ultrasound-guided continuous caudal block. Mid-sagittal plane lumbar ultrasound (Sonosite SII, FUJIFILM Sonosite, Inc., USA) showed the dural sac end at S4 vertebral level, significantly lower for […]
