BackgroundAnaesthetic management of microvascular head and neck free flap surgery is based on physiological principles, but data on how these affect clinical outcomes in this challenging group are limited. There are no evidence-based guidelines available in this area.MethodsTo establish current perioperative anaesthetic practice by surveying all UK centres performing head and neck free flap surgery. Anaesthetists from 73 centres performing head and neck microvascular reconstructive surgery in the UK were asked to complete a structured online survey. The survey included general questions, a hypothetical clinical scenario with multiple choice questions and questions about perioperative management. The main outcomes measured were protocols of pre-operative assessment, perioperative fluid and blood pressure strategies, monitoring and post-operative management.ResultsSeventy-three units were contacted, and fifty-five responded (75%). Most respondents performed up to two cases per month. Opinion was divided as to how best to manage intra-operative blood pressure, fluid balance, pre-operative assessment and monitoring. Notably 52% preferred crystalloid infusion to increase blood pressure, while 35% stated crystalloids were contraindicated.ConclusionsCurrently in the UK, anaesthetic perioperative management for head and neck free flap transfer is varied, reflecting the paucity of high-quality data in this area; but some techniques, in particular avoidance of excessive crystalloid use, is associated with improved flap outcome.© 2013 The Acta Anaesthesiologica Scandinavica Foundation.
