AUTHORS: Kiberenge, Roy, K., MD et al Anesthesia & Analgesia: January 2018 – Volume 126 – Issue 1 – p 120–126 BACKGROUND: Radial arterial cannulation is most commonly done using palpation, but the use of ultrasound has increased the cannulation success rate. This improvement, albeit significant, has not led to a very high success rate especially in […]
Read MoreAUTHORS: da Silva Ramos, et al Anesthesia & Analgesia: January 2018 – Volume 126 – Issue 1 – p 102–110 BACKGROUND: Electrical impedance tomography (EIT) is a noninvasive imaging method that identifies changes in air and blood volume based on thoracic impedance changes. Recently, there has been growing interest in EIT to measure stroke volume (SV). The […]

Currently, preoperative risk assessment is based on a composite of medical examination and a […]
Read MoreAuthor: Simon Gelman, M.D., Ph.D., F.A.N.Z.C.A. Anesthesiology published on May 30, 2018. Aortic cross-clamping (AoX) and unclamping are associated with severe hemodynamic disturbances in virtually all organs and systems. The main hemodynamic changes induced by AoX result from an increase in impedance to aortic flow, an increase in systemic vascular resistance and afterload, blood volume redistribution […]
Read MoreA recent drop in stillbirths and newborn deaths in the United States might be linked to an increase in term or near-term births, a new study suggests. The study, published Monday in the journal JAMA Pediatrics, looked at more than 99% of US live births and stillbirths between 2007 and 2015 using data from the […]
Read MoreAuthors: Kyoung-Ho Ryu, M.D. et al Anesthesiology 6 2018, Vol.128, 1092-1098. Background: Minimum alveolar concentration (MAC) has traditionally been used to compare the potency of volatile anesthetics. However, as it reflects the spinal mechanism of immobility rather than the cerebral mechanism of analgesia and hypnosis, it is doubtful that equi-MAC connotes equivalent analgesic or hypnotic potency. […]

This study is designed to evaluate the effects of administration of zinc lozenges on POST. METHODS: Seventy-nine patients […]
Read MoreAUTHORS: Cameron, Matthew, J., MDCM et al Anesthesia & Analgesia: January 2018 – Volume 126 – Issue 1 – p 33–38 BACKGROUND: Postoperative atrial fibrillation (POAF) is associated with early and late morbidity and mortality of cardiac surgical patients. Prophylactic treatment of atrial fibrillation (AF) has been recommended to improve outcome in cardiac surgical patients at high […]
Read MoreAuthors: Eric C. Sun, M.D., Ph.D. et al Anesthesiology published on May 29, 2018. Background: In the United States, anesthesia care can be provided by an anesthesia care team consisting of nonphysician providers (nurse anesthetists and anesthesiologist assistants) working under the supervision of a physician anesthesiologist. Nurse anesthetists may practice nationwide, whereas anesthesiologist assistants are restricted to […]
Read MoreI wanted to share this with our readers because I am an old guy so this is important to at least me. Authors: Lamb SE et al. BMJ 2018 May 16. Supervised exercise might improve physical fitness but doesn’t help cognition. Evidence is mixed on whether physical exercise improves cognitive impairment. In this trial, U.K. investigators […]
