Postanaesthesia care units are standard parts of hospital care in most European Union countries. Their main purpose is to identify and immediately treat early complications of surgery or anaesthesia, before they develop into deleterious problems. This review, prepared by the Working Party on Post Anaesthesia Care of the European Board of Anaesthesiology. European Union of Medical Specialists (Union Européenne des Médecins Spécialistes) and approved by the European Board and Section of Anaesthesiology, gives recommendations on relevant aspects of organization, responsibilities, methods, safety and quality control of postanaesthesia care.
