COMPARATIVE STUDY OF C-MAC VIDEO LARYNGOSCOPE VERSUS MACINTOSH LARYNGOSCOPE FOR INTUBATION IN ELECTIVE SURGERY

Abstract

Background: The aim of the study is to compare the C-MAC video laryngoscope with Macintosh laryngoscope for intubation in patients for elective surgery. Methods: This was a prospective and interventional randomized comparative single blinded study in Asian 
Institute of Medical Sciences (AIMS) Faridabad, after due approval from Institutional Ethics Committee from November 2020 to May 2021. 70 patients of age 18-60 years with American society of Anaesthesiologist (ASA) category I and II and Mallampati Classification I and II under elective surgery were included in the study. Patients were then randomly allocated into C-MAC group (Group A) and the Macintosh Laryngoscope group (Group B) by simple random sampling technique. The comparison among the two groups was based on the total time and number of attempts required for intubation, the glottic view obtained, need for external laryngeal maneuver and/or stylet, and hemodynamic variations observed during the procedure. The statistical analysis was done using SPSS version 21.0. p < 0.05 was considered as significant.
