[Management of pediatric airway--anatomy, physiology and new developments in clinical practice].

Abstract

Due to the special features of paediatric anatomy and physiology, the expected and unexpected difficult paediatric airway is one of the major challenges to every anaesthesiologist, paediatrician and emergency physician. During the last years, some new devices have been made available to improve airway management in children and infants, and several studies have advanced our understanding of the risks and benefits of our clinical practice. Certain risk factors for airway related problems during anaesthesia in children having a "cold" have been identified, and there are new aspects of the controversy concerning the use of cuffed endotracheal tube (ETT) in children. New video assisted systems have been introduced for the management of the difficult airway in paediatric patients, and new applications for well-known devices have been suggested, e.g. the laryngeal mask airway (LMA) serving as guidance for fibreoptic intubation. Recent studies have also demonstrated specific problems with the LMA in infants, as well as possible advantages of a new prototype LMA for children, similar to the ProSeal. Furthermore, the following review presents data about the use of the Cuffed Oropharyngeal Airway (COPA) and the Laryngeal Tube (LT) in paediatric patients.
