Incidents relating to paediatric regional anaesthesia in the first 8000 cases reported to webAIRS

Abstract

Regional anaesthesia is an essential tool in the armamentarium for paediatric anaesthesia. While largely safe and effective, a range of serious yet preventable adverse events can occur. Incidence and risk factors have been described, but few detailed case series exist relating to paediatric regional anaesthesia. Across Australia and New Zealand, a web-based anaesthesia incident reporting system enables voluntary reporting of detailed anaesthesia-related events in adults and children. From this database, all reports involving paediatric regional anaesthesia (age less than 17 years) were retrieved. Perioperative events and their outcomes were reviewed and analysed. When offered, the reported contributing or alleviating factors relating to the case and its management were noted. This paper provides a summary of these reports alongside an evidence review to support safe practice. Of 8000 reported incidents, 26 related to paediatric regional anaesthesia were identified. There were no deaths or reports of permanent harm. Nine reports of local anaesthetic systemic toxicity were included, seven equipment and technical issues, six errors in which regional anaesthesia made an indirect contribution and four logistical and communication issues. Most incidents involved single-shot techniques or a neuraxial approach. Common themes included variable local anaesthetic dosing, cognitive overload, inadequate preparation and communication breakdown. Neonates, infants and medically complex children were disproportionately represented, highlighting their inherent risk profile. A range of preventable incidents are reported relating to patient, systems and human factors, demonstrating several areas for improvement. Risk stratification, application of existing dosing and administration guidelines, and effective teamwork and communication are encouraged to ensure safe regional anaesthesia in the paediatric population.
