Humidification of inspired gases is vital for the safe practice of anesthesia. This article focuses on the basic science of humidification, its measurement and its relevance in anaesthesia clinical practice.
Coronary angiography is increasingly performed pre-operatively to investigate for the presence of coronary artery disease. As peri-operative physicians, we need a basic understanding of coronary angiography and terminology used. This tutorial aims to give an overview of coronary anatomy and provide a working knowledge of coronary angiography.
This tutorial is a comprehensive review of up to date evidence regarding management of both the elective patient with known or suspected sleep apnoea and the emergency patient. Together with a practical approach to risk stratification and management, this tutorial provides a holistic approach to perioperative management of these patients.
This article highlights a selection of recent publications from various anaesthesia journals.
This article presents case studies related to cerebral challenge.
This article defines standards and makes recommendations to help guide maternity and critical care providers in establishing and managing a maternal critical care service. Originally published as Anaesthesia Tutorial of the Week #310, 27 October 2014, edited by Matt Rucklidge.
Appropriate management of hyponatraemia is often challenging because of both numerous pathophysiological mechanisms and multiple underlying pathological conditions. After revising the normal control of sodium balance this article will review the causes, classification, diagnosis and management of hyponatraemia. An algorithm for investigations and treatment is provided at the end of this article. Originally published as Anaesthesia Tutorial of the Week #314, 2 April 2015, edited by William English.
The aim of this article is to provide the reader with an overview of the current guidelines and evidence for the management of sepsis in children. Sepsis is a major cause of morbidity and mortality in children and, although mortality rates are lower in children than in adults, they are estimated at about 10% in severe sepsis.

Knowledge of the pharmacological differences between opioids can be applied to select the appropriate drug for the relevant clinical setting and minimise the impact of side-effects. Over the last 20 years more information regarding the pharmacodynamics and pharmacokinetics in terms of opioid receptor dimers and oligomers, second messenger system effects and genotyping has come to light.

A wrist block is the technique of blocking terminal branches of some or all of the six nerves that supply the wrist, hand and fingers. The combination of nerves that need to be blocked depends upon the exact location of surgery. This block can be used to provide regional anaesthesia for a patient undergoing surgery awake or as an analgesic technique to be used in combination with general anaesthesia or brachial plexus block (BPB) using short-acting local anaesthetic (the wrist block will provide prolonged pain relief once the BPB has worn off).
