Apnoeic Oxygenation during Simulated Difficult Intubation in Obese Patients: Comparison of Buccal Ring, Adair and Elwyn Tube Versus Nasal Cannula: A Prospective Randomized Controlled Trial.

Background: Apnoeic oxygenation is an established method of increasing safe apnoea times during intubation and this is of more importance in obese patients. The usefulness of buccal Ring, Adair and Elwyn (RAE) oxygenation has been established in previous studies, however a head-to-head comparison with nasal cannula (NC) is lacking.

Aim: The aim of this study was to compare apnoea time with buccal RAE (BR) versus NC in obese patients.

Association between a prolonged corrected QT interval and outcomes in patients in a medical Intensive Care Unit.

Introduction: Patients admitted into a medical Intensive Care Unit (ICU) have varying illnesses and risk factors. An electrocardiogram (ECG) is a useful tool to assess the cardiac status. The aim of the study was to determine the prevalence of QT prolongation of the ECG in patients admitted to a medical ICU in a tertiary hospital, to assess outcomes in terms of mortality, cardiovascular events, and duration of ICU stay.
