Why you should read this article: • To understand the post-operative monitoring requirements for patients to identify any signs of deterioration • To adopt the ABCDE (airway, breathing, circulation, disability and exposure) approach to patient assessment in your practice • To be aware of the immediate response required to prevent further patient deterioration, preserve patient safety and provide effective care, in accordance with clinical guidelines, where post-operative complications are identified This article details a case study of the immediate post-operative care of an elective adult patient who presented in a postanaesthetic care unit. It outlines the systematic ABCDE (airway, breathing, circulation, disability and exposure) approach that was used to assess the patient and describes the actions that were taken to manage an airway obstruction that occurred. It also discusses the monitoring of patients required post-operatively, including capnography, peripheral oxygen saturations, blood pressure, temperature, heart rate and respiratory rate, which can assist in the identification and management of any issues and support optimal patient outcomes.
