Abstract

Introduction: Perioperative mortality and morbidity remain substantial in acute surgery. Risk factors include known cardiovascular disease, but preoperative screening is insensitive to occult cardiopulmonary conditions. Focused cardiac ultrasound (FOCUS) can disclose both structural and functional cardiac disease and provides insight into the patient’s haemodynamic status. This study aims to clarify whether preoperative FOCUS changes clinical outcomes in high-risk patients. Methods: This is a multi-centre, randomised, controlled, prospective study including patients ≥ 65 years of age scheduled for acute/emergency abdominal-or orthopaedic surgery. A total of 800 patients will be randomised to ± application of preoperative FOCUS. The primary endpoint is the proportion of patients admitted to hospital > 10 days or death within 30 days of surgery. The secondary endpoints include changes in the anaesthesia approach facilitated by FOCUS, biomarkers of organ function and perioperative complications. Conclusions: The knowledge generated from this study may facilitate changes in the anaesthesia evaluation and decision process and, consequently, in the entire perioperative anaesthesia clinical practice. The study has the potential to reduce the risk of perioperative cardiopulmonary complications which directly implies improved patient outcome and reduced hospital costs.
