A Comparative Study Between Laryseal Pro Extraglottic Device and Ambu Aura Gain Laryngeal Mask as a Conduit for Fiberoptic Tracheal Intubation in Pediatric Population

Overview

This study aims to compare between Laryseal Pro and Ambu Aura Gain extraglottic devices as conduits for fiberoptic endotracheal intubation regarding time of endotracheal intubation in pediatric population.

Airway management is a skill that must be mastered by all anesthesiologists. Since the introduction of the extraglottic airway devices (EADs) in the early 1980s, the EAD has become a central element in the management of airway in adults and children. Some of the EADs are specially designed to allow endotracheal intubation whether blindly or with the use of fiberoptic bronchoscope (FOB). So, with the use of EAD, it is possible to provide adequate oxygenation and at the same time perform fibreoptic bronchoscopy-guided trans-device intubation, providing less hemodynamic stress response and less postoperative complications. As patient's safety always comes first, the use of flexible bronchoscopes became more widespread, strong literature favored visualization of the glottis over blind intubation. So, the use of the intubating EADs as aconduit for fiberoptic intubation is favoured over blind intubation. In addition, FOB guided intubation through EAD is a central step in the algorithm of the expected as well as the unexpected difficult airway in children. The Ambu Aura Gain is a second-generation EAD which was presented in the clinical field in 2018. It is characterized by a wide inner diameter tunnel which has a C shaped curve with an angle guiding the endotracheal tube (ETT) into the laryngeal inlet. The presence of gastric access through a second port helps to vent the stomach and for gastric suctioning. In a previous study The Ambu Aura Gain has been shown to be an effective conduit for FOB guided intubation regarding feasibility of FOB-guided intubation, oropharyngeal leak pressure, gastric leak pressure and fibreoptic view in small children. Laryseal Pro is a novel device and a new generation of EADs that was developed in 2018. It is believed to be a method for rapid, secure airway management which improves patient safety with gastric access. It has a catheter channel for efficient removal of fluids and gastric content, reducing risk of aspiration and integrated fenestrated flap that protects from blockage with minimal increase in flow resistance. Besides, it elevates the epiglottis for easy trauma-free ETT or bronchoscope insertion. In spite of that, it's clinical performance and efficacy as a conduit for fiberoptic tracheal intubation in pediatric population hasn't been studied by any study in literature till the present time. To our knowledge, this is the first study to evaluate the clinical efficacy of laryseal Pro EGA in pediatric population. In this study we will compare between two extra glottic devices, Laryseal Pro and Ambu Aura Gain regarding clinical performance and efficacy with respect to the time of endotracheal intubation through fibreoptic, laryngeal view grade, airway seal pressure, success rate of intubation, number of attempts of intubation, number of attempts of SGA insertion and complications in pediatric population.
