Transfusion Threshold for Abdominal Cancer Surgery Patients

Published in Anesthesiology 2015 Jan 122:29 Authors: Pinheiro de Almeida J et al. A hemoglobin level of 9 g/dL was superior to 7 g/dL as a trigger for transfusion. Randomized trials have shown favorable outcomes with a restrictive red-cell transfusion strategy — that is, not transfusing until hemoglobin levels are <7 g/dL in general critical-care […]

Structural Comparisons of Ligand-gated Ion Channels in Open, Closed, and Desensitized States Identify a Novel Propofol-binding Site on Mammalian γ-Aminobutyric Acid Type A Receptors

Published in The Journal of the American Society of Anesthesiologists on 1 2015. Authors: Nicholas P. Franks, F.R.C.A., F.Med.Sci., F.R.S. Background: Most anesthetics, particularly intravenous agents such as propofol and etomidate, enhance the actions of the neurotransmitter γ-aminobutyric acid (GABA) at the GABA type A receptor. However, there is no agreement as where anesthetics bind […]

Repeated Exposure to Ketamine–Xylazine during Early Development Impairs Motor Learning–dependent Dendritic Spine Plasticity in Adulthood

Published in The Journal of the American Society of Anesthesiologists on 1 2015. Authors: Lianyan Huang, Ph.D.; Guang Yang, Ph.D. Background: Recent studies in rodents suggest that repeated and prolonged anesthetic exposure at early stages of development leads to cognitive and behavioral impairments later in life. However, the underlying mechanism remains unknown. In this study, […]

Nocebo effects and negative suggestion in anesthesia

Published in Der Anaesthesist (Oct 2014) Authors: Zech N, Seemann M, Hansen E; Anesthetists have an impact on patients and healing processes not only through drugs, interventions and therapy but also significantly by their words and personality. A substantial part of observed side effects is caused by nocebo effects and negative suggestion, i.e. by the doctor […]
