Discordance in Grading Methods of Aortic Stenosis by Pre-Cardiopulmonary Bypass Transesophageal Echocardiography

Anesthesia & Analgesia: April 2016 – Volume 122 – Issue 4 – p 953–958 AUTHORS: Whitener, George MD et al BACKGROUND: Current guidelines define severe aortic valve stenosis (AS) as an aortic valve area (AVA) ≤1.0 cm2 by the continuity equation and mean gradient (ΔPm) ≥ 40 mm Hg. However, these measurements can be discordant when […]

A Comparison of the Haider Tube-Guard(R) Endotracheal Tube Holder Versus Adhesive Tape to Determine if This Novel Device Can Reduce Endotracheal Tube Movement and Prevent Unplanned Extubation.

Anesthesia & Analgesia: March 2016 AUTHORS: Buckley, Jack C. MD et al BACKGROUND: Endotracheal tube security is a critical safety issue. We compared the mobility of an in situ endotracheal tube secured with adhesive tape to the one secured with a new commercially available purpose-designed endotracheal tube-holder device (Haider Tube-Guard(R)). We also observed for the […]
