Comparison of Video Laryngoscopy Versus Direct Laryngoscopy for Orotracheal Intubation Among Adults in Emergency Department

Overview

This is an open-label, single center, prospective, randomized, comparative, intervention study. The goal of this study is to compare the success rate of video laryngoscopy vs direct laryngoscopy for first pass oro tracheal intubation. The other question it aims to answer are: 1. To assess the adverse events during video laryngoscopy 2. To assess the adverse events during direct Laryngoscopy 3. To compare the first pass success rate of DL vs VL according to demographic profile (age and sex)

All consecutive patients presenting in Emergency medicine room requiring intubation, will be recruited in this study after taking informed written consent from the patients' family, excluding those falling in exclusion criteria. Direct laryngoscopy will be done by Mackintosh Laryngoscope with blade no 3 or 4. Video Laryngoscopy will be done by Mcgrath Mac Video Laryngoscope in respective groups. Intubations will be done by ER physicians and Emergency fellows of Emergency department. The total number of required sample size will be calculated and the obtained number will be divided in a group of 21 with block of 6 each. After randomizing the group and the block from a computerized software, a total of 21 envelope will be prepared in a consecutive manner and the patient will be intubated as per the pre decided blocks. All the patients in emergency who require intubation and falling into the inclusion criteria will be assessed. Informed written consent will be taken from the patient's family explaining that they will be a part of study and either of the laryngoscopy method will be used in them. Informed consent will be taken by one of the investigators, (ER physicians and emergency medicine fellow) who will be performing intubations in them.Inclusion criteria- * Age 18 years * Patient requiring orotracheal intubation * Those who give written informed consent Exclusion criteria- * Pregnancy * Intubations done by medical officers Randomization- * The consecutive patients will be assigned numbers serially from one. * Block randomization of the patients in two arms will be done by using computerized software. A total of 63 patients in each arm with total 126 patients will be included in the study. Blocks of 6 will be taken with total 21 groups. With using the software, random group will be selected and intubations will be done accordingly. Demographic and clinical profile of patients in both arms will be recorded. Two treatment arms- * Arm A- Orotracheal intubation done by Direct Laryngoscopy * Arm B- Orotracheal intubation done by Video Laryngoscopy Outcomes Primary- First pass success of direct laryngoscopy in oro tracheal intubation First pass success of video laryngoscopy in oro tracheal intubation Secondary- Complications rates between two methods. Use of alternative methods for ventilation or oxygenation between two methods Better visualization of Cormack-Lehane grading between two methods
