Extracorporeal membrane oxygenation (ECMO) is the short-term (days to weeks) support of patients with severe respiratory and/or cardiac failure. The use of these devices has been well established in paediatric and post-heart and lung transplantation patients; however, its use in patients with severe acute respiratory distress syndrome (ARDS) has gained acceptance as standard clinical practice over the past decade. ⋯ In this review, we highlight the uses, subtypes, physiology, normal appearances, and complications of ECMO. An example of the chronological radiographic images in the perioperative period demonstrates the importance of discriminating normal appearances associated with EMCO.

To report the authors' experience with the administration of four gadolinium-based contrast agents (GBCA; gadopentetate dimeglumine, gadofosveset trisodium, gadoxetate disodium and gadobenate dimeglumine) in a large study population at a single, large academic medical centre. ⋯ The overall rate of adverse reaction to GBCAs was 0.1%. The rates of reactions were highest in gadofosveset trisodium with (0.80%), followed by gadoxetate disodium (0.31%), gadobenate dimeglumine (0.22%) and gadopentetate dimeglumine (0.09%).
