The following abstracts were presented at the Annual Spring Meeting of the Association of Cardiothoracic Anaesthetists (ACTA) in Cambridge, June 2013

Due to the rising number of older adults requiring cardiac surgery, it is increasingly important to identify methods of reducing postoperative cognitive dysfunction (POCD) [1]. Deep anaesthesia has been associated with poorer long-term cognitive outcomes following non-cardiac surgery [2]. We are conducting an on-going study to determine whether maintaining optimal depth of anaesthesia and cerebral oxygenation reduces POCD following cardiac surgery in older adults. Here we present the study design and blinded preliminary cognitive outcomes.
