Obesity is a worldwide epidemic and official figures demonstrate a rising prevalence, both in the UK and globally. Increasingly, there is a recognised place for surgical intervention in carefully selected patients, but there is limited understanding of the pathway and process among non-specialist clinicians. This article summarises the available guidelines and literature on the surgical management of obesity for hospital physicians, surgeons and GPs. The focus is on appropriate referral criteria, key bariatric procedures, postoperative management and, most importantly, the complications of surgery and how to recognise them.

Ventilatory support is vital for the management of severe forms of COVID-19. Non-invasive ventilation is often used in patients who do not meet criteria for intubation or when invasive ventilation is not available, especially in a pandemic when resources are limited. ⋯ Pulmonary barotrauma results from positive pressure ventilation leading to elevated transalveolar pressure, and in turn to alveolar rupture and leakage of air into the extra-alveolar tissue. This article reviews the literature regarding the use of non-invasive ventilation in patients with acute respiratory failure associated with COVID-19 and other epidemic or pandemic viral infections and the related risk of barotrauma.
