Abstract

Although it is essential to take a history and examine every child prior to airway management, preoperative anticipation of a difficult airway is not totally reliable and therefore it is wise to be prepared for the unexpected difficult airway. Information about the airway can be gained from previous medical records, current history, physical examination and other tests. A natural consequence of airway assessment is development of an airway plan. Important anatomical and physiological features may be identified in an airway assessment which can then have a direct influence on the subsequent airway plan. Managing the predicted difficult airway is usually elective. This allows proper preparation of equipment, assistants, expertise and the environment required for the airway plan. This article will discuss paediatric airway assessment, outline those features that contribute to airway difficulty, and identify indications and risk factors associated with various airway techniques. Key objectives for an airway management plan are to maintain oxygenation and avoid trauma. This involves adopting techniques that avoid hypoxia and provide a high success rate with minimum attempts.
