Truview Videolaryngoscopy and Mcgrath Videolaryngoscopy with Direct Laryngoscopy in Paediatric Airway Management - A Randomised Comparative Study

True view and McGrath compared with direct laryngoscopy in paediatric patients.

Abstract

Background: Videolaryngoscopes were developed mainly to manage difficult airway intubation. They also gained a great deal of attention recently as a new airway system for use in paediatric airway management. Subjects and Methods:183 children of bodyweight 10 30 kgs under ASA Physical Status Class I & II with normal airway undergoing general anaesthesia requiring endotracheal intubation were included   in the study. Based on the laryngoscope used, they were divided into three groups (Truview Group- TV, McGrath Group MC, Macintosh Group - DL) of 61 children each. Time to intubation, number of attempts, intubation conditions were recorded. Results: The mean POGO score was significantly higher in Group TV (99.18 4.48) than Group MC (95.5 9) and Group DL (71 23.79). Group MC had improved glottic opening score than Group DL. Time Taken for intubation (in seconds) was significantly longer in the Group TV (40.15 9.93) than Group MC (27.2  4.996) and Group DL (17.23  2.88). Time to intubation was significantly longer in Group MC then Group DL. Conclusion:  Though   the Videolaryngoscopes offer excellent glottic visualization when compared to the conventional laryngoscope, the time taken for intubation is significantly prolonged with the videolaryngoscopes in the Paediatric population.
