Comparison of Airway Maneuvers Manual in line stabilization[MILS],Modified Jaw thrust, Conventional maneuver for Oro tracheal Intubation during Direct Laryngoscopy

Abstract

Background: During performing orotracheal intubation with direct laryngoscopy adequate laryngeal visualization depends on proper airway maneuvers. There are different type of airway maneuvers. Aim: This study aimed to compare airway maneuvers ; MILS, jaw thrust , conventional maneuver to assess better laryngeal visualization and ease of intubation among them and associated complications. Material & Methods: This observational study was conducted in 90 adult patients. Patients divided in to three groups. Laryngoscopy and intubation in group M was done in MILS and in group J jaw thrust , In Group C as conventional maneuver performed. Laryngeal visualization assessed using modified Cormack lehane (CL)grading and ease of intubation assessed by usingintubation time, number of attempts between these three groups. The data were compared using Anova test, chi-square test. Results: While comparing between these groups better laryngeal visualization seen in jaw thrust group while the MILS maneuver worsen the view. Conclusion: The present study concluded that jaw thrust maneuver improved the laryngeal visualization and conventional maneuver made intubation faster and easy.
