A COMPARATIVE STUDY OF McGRATH MAC VIDEO LARYNGOSCOPE AND MACINTOSH LARYNGOSCOPE FOR ORO-TRACHEAL INTUBATION IN NORMAL AIRWAY.

Abstract

Background- Oro-tracheal intubation is practiced for oxygenation & ventilation along with inhalational anesthetic delivery and in emergency conditions for securing airway. The objective of our study was to evaluate and compare the intubations by McGrath VL and Macintosh laryngoscope. A prospective, observational s Methodology- tudy in 80 patients undergoing elective surgical procedures with normal airway. All patients were premedicated and pre-oxygenated with 100% O2 for ve minutes and induced with inducing agent inj. Propofol 2mg/kg and neuromuscular blocking agent inj. Succinyl choline 1.5 mg/kg. Patients were divided into 2 groups for Macintosh Laryngoscope and McGrath VL. We have noted TTI, number of intubation attempts, C-L grade, POGO score, modication of positioning, the requirement of external laryngeal pressure manipulation and complications during and after intubations. Haemodynamic parameters were monitored and recorded. Time to intubate in McG VL Group (38.92 ± Observation & Results- 11.07) was signicantly shortened than Mac L Group (57.95 ± 10.37)(). Percentage of glottic opening was better in McGrath Video Laryngoscope group (McG VL) than Macintosh laryngoscope group (Mac L). Incidence of complications were less in McG VL Group than Mac L group. The study Conclusionconcluded that McGrath MAC Video laryngoscope is better than Macintosh laryngoscope for oro-tracheal intubation in normal airway as it provides earlier time to intubate, signicantly superior glottic view, more rst attempt success rate without any complications and stable vitals.
