PHYSIO+++: protocol for a pilot randomised controlled trial assessing the feasibility of physiotherapist-led non-invasive ventilation for patients with hypoxaemia following abdominal surgery.

Introduction: Few clinical trials have investigated physiotherapy interventions to treat hypoxaemia following abdominal surgery. The objective of this study is to determine the feasibility and safety of conducting a clinical trial of physiotherapist-led non-invasive ventilation (NIV).

Methods And Analysis: This single-centre, 50-patient, parallel-group, assessor blinded, pilot feasibility randomised controlled trial with concealed allocation will enrol spontaneously ventilating adults with hypoxaemia within 72 hours of major abdominal surgery.

An evaluation of the role of mixing techniques in the observed variation in acetylcysteine infusion concentrations.

Intravenous acetylcysteine is commonly prescribed as a course of three infusions for the management of paracetamol poisoning. Previous studies have demonstrated large variation in administered doses of intravenous acetylcysteine, which has been attributed to numerous factors, including inadequate mixing of infusion bags. The aim of this study was to determine whether the amount of mixing of infusion bags contributes significantly to this variation.

Canadian Association of Gastroenterology policy on the application for, and implementation of, clinical practice guidelines.

An important mandate of the Canadian Association of Gastroenterology (CAG), as documented in the Association's governance policies, is to optimize the care of patients with digestive disorders. Clinical practice guidelines are one means of achieving this goal. The benefits of timely, high-quality and evidenced-based recommendations include: Enhancing the professional development of clinical members through education and dissemination of synthesized clinical research; Improving patient care provided by members by providing focus on quality and evidence; Creating legislative environments that favour effective clinical practice; Enhancing the clinical care provided to patients with digestive disease by nongastroenterologists; and Identifying areas that require further information or research to improve clinical care.
