305 Surgical complexity and intra-operative fluid management influence duration of ICU care following cytoreductive surgery

Introduction Increased routine radical cytoreductive surgery for advanced ovarian cancer has resulted in higher utilisation of intensive care settings for post-operative recovery. We aimed to identify peri-operative variables associated with extended ICU admission. Methods A retrospective review of all patients admitted to the ICU following cytoreductive surgery for ovarian cancer in a tertiary referral centre from 2015–2019. Patients were categorised according to length of stay, Results 56 patients were admitted to the ICU immediately post-operatively, 37 for Conclusions Utilising identified intra-operative risk factors to perform individualised risk assessments for prolonged ICU admission could be used to assist communication between surgeons and intensivists to improve planning of ICU resources.
