Truview PCDTM Video Laryngoscope versus McCOY Laryngoscope for Tracheal Intubation: A Comparative Study.

ABSTRACT

Background: McCoy laryngoscope and video laryngoscopes are being increasingly used and have a definitive advantage over conventional laryngoscopes in management of potentially difficult airways. The aim of our study was to compare relative effectiveness of McCoy laryngoscope and True view PCDTM video laryngoscope in patients undergoing oral tracheal intubation. Methods: Fifty patients of American Society of Anaesthesiologists (ASA) grade I and II, aged 20 – 50 years, posted for elective surgery under general anaesthesia were randomly allocated into Group T (Truview group, n=25) and Group M (McCoy group, n=25). The two groups were compared for demographic data, intubation difficulty score (IDS), Cormack-Lehane (CL) grade, POGO score, time to intubation, number of intubation attempts and haemodynamic parameters. Results: The demographic data and ASA status was comparable in both the groups. Group T had a significantly less IDS score as compared to Group M (p < 0.001). Seventeen patients in Group T and 8 patients in Group M had IDS = 0. The CL grade and POGO scores were better in Group T than in Group M. Intubation was successful in the first attempt in 94% patients in Group T and 88% patients in Group M. There was a transient increase in HR and NIBP after intubation in both the groups which returned back to the baseline within 5 minutes. No incidence of hypoxia and airway trauma was noted in the two groups.Conclusion: Truview PCDTM video laryngoscope resulted in better glottic visualization with lower IDS than McCoy laryngoscope in patients undergoing oral tracheal intubation.
