Video laryngeal masks in airway management

Abstract

Introduction: Video laryngeal masks have become alternatives to classical supraglottic airway devices in recent years. This review provides information on the background of these new medical devices, the most popular and widely used video laryngeal masks, their advantages, disadvantages and their main applications in airway management.

Areas covered: In this review, the physical differences between video laryngeal masks and second-generation laryngeal mask airways, and their properties in specific clinical settings are discussed.

Expert commentary: To limit airway-related morbidity, an optimal position of supraglottic airway devices must be the primary goal. Extensive research has shown that blindly inserted laryngeal mask can be malpositioned in 50% to 80% of the cases. Therefore, blind insertion should be the exception rather than the rule unlike current practice. Video laryngeal mask airways have clear advantages in routine use and in difficult airway management since they allow a vision-guided technique. Henceforth, the properties perceived in clinical practice must be endorsed with quality clinical evidence.
