Evaluation of the pediatric airway: a review

Abstract

The airway in the pediatric age group is a complex structure that extends from the external nares to the junction of the larynx and trachea. The airway of pediatric patients has significant anatomical and physiological differences compared to the adult age group. The difficult airway in children is an important contributor to both morbidity and mortality of the patient. The symptoms and signs of pediatric patients with respiratory distress depend on the site and severity of the obstruction. It is essential to evaluate and localize the site and etiology of the obstruction of the pediatric airway. Pediatric otolaryngologists and anesthetists must have a strategy for managing the predicted difficult pediatric airway. Flexible nasopharyngolaryngoscopy is the gold standard method for predicting or knowing the difficult airway in children. The majority of pediatric patients who have difficult airways are identified preoperatively. Knowledge of the airway differences between the pediatric and adult ages will help clinicians anticipate and troubleshoot difficulties that may happen. This review article aims to discuss the evaluation of the pediatric airway including its anatomy and physiology of the airway, proper history taking, clinical examination, and investigations.

Airway Management and General Anesthesia in Pediatric Patients with Disabilities Undergoing Dental Surgery: A Retrospective Study

“…However, some peculiarities should be emphasized in the pediatric setting, which are particularly important when the patient is also uncooperative. In particular, the physical assessment phase is often incomplete or even absent because the patient is not cooperative in performing the necessary maneuvers [20]. Syndromic or malformative clinical pictures, which may make it difficult to ensure adequate oxygenation and ventilation, should also be appropriately considered in the context of the most relevant conditions of difficult airway in pediatric age [21].…”
