The C-MAC Video Laryngoscope Helps Presbyopic Anesthetists

Overview

Endotracheal intubation is the de facto gold standard for airway management especially in neonatal and pediatric anesthesia . An efficient neonatal airway management is challenging even in the most experienced hands and the prevalence of difficult intubation in pediatric anesthesia varied greatly on a wide range.

Neonatal intubation is a life-saving procedure, which requires skilled operator but still may cause direct tissue trauma and precipitate adverse reactions. However, intubation with videolaryngoscope (VL) requires less force than with a direct laryngoscope to minimize the possibility of these adverse events. The recent Brazilian recommendations for management of pediatrics difficult airways included proper assessment, preparation, positioning, pre-oxygenation, minimizing trauma, maintenance of arterial oxygenation and the implementation of the advanced tools as VL, flexible intubating bronchoscopy, and supraglottic devices. The recent British recommendations also advised for the use VL with an age-adapted standard blade as first choice for tracheal intubation and the use of a stylet to reinforce and preshape tracheal tubes in case of the use of hyperangulated VL blades . Considering the recent interest in assessing the performance of various VLs in pediatric anesthesia, the C-MAC® (Karl Storz, Germany) VL with standard Miller blade sizes #0 and #1, is a widely used in neonates and infants for its provision of superior-quality glottis view in comparison to the McGrathTM MAC size #1 blade and direct laryngoscopy. Presbyopia is defined as disordered eye adjustment function and affects middle aged people leading to difficult viewing close objects and is corrected with magnifying lens. Earlier studies documented that presbyopic aged anesthetists find difficulty when trying to view a patient's larynx at a close distance and this difficulty is surely magnified on dealing with intubation of neonates and children
