Sewage Is Helping Cities Flush Out the Opioid Crisis

By Keridwen Cornelius on May 25, 2018 Poop studies are helping communities make intervention decision The two-liter bottle of sewage sitting in a lab at Arizona State University is the yellow-brown color of smog. It was shipped overnight from one of a half dozen cities that have recently asked A.S.U. to begin studying their waste for chemical signatures […]

Ultrasound-Guided Dynamic Needle Tip Positioning Technique Versus Palpation Technique for Radial Arterial Cannulation in Adult Surgical Patients: A Randomized Controlled Trial

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 […]

Estimation of Stroke Volume and Stroke Volume Changes by Electrical Impedance Tomography

AUTHORS: 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 […]

A Comparison of Three Frailty Indices in Predicting Morbidity and Mortality After On-Pump Aortic Valve Replacement

AUTHORS: Esses, Gary, MD et al Anesthesia & Analgesia: January 2018 – Volume 126 – Issue 1 – p 39–45 BACKGROUND: Aortic valve replacement is a high-risk surgery (3%–5%, 30-day mortality) performed on approximately 30,000 elderly patients a year in the United States. Currently, preoperative risk assessment is based on a composite of medical examination and a […]

My Love Affair with the Venous System

Author: 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 […]

US stillbirths and newborn deaths down 11.5%, study says

A 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 […]

Does Equi–Minimum Alveolar Concentration Value Ensure Equivalent Analgesic or Hypnotic Potency?: A Comparison between Desflurane and Sevoflurane

Authors: 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. […]

The Effect of Zinc Lozenge on Postoperative Sore Throat: A Prospective Randomized, Double-Blinded, Placebo-Controlled Study

AUTHORS: Farhang, Borzoo, DO et al Anesthesia & Analgesia: January 2018 – Volume 126 – Issue 1 – p 78–83 BACKGROUND: Postoperative sore throat (POST) is commonly seen after endotracheal intubation, and oral zinc prevents oral mucositis associated with chemotherapy. This study is designed to evaluate the effects of administration of zinc lozenges on POST. METHODS: Seventy-nine patients […]

Prospective External Validation of Three Preoperative Risk Scores for Prediction of New Onset Atrial Fibrillation After Cardiac Surgery

AUTHORS: 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 […]
