Comparative study between McCoy laryngoscope versus the tascope in orotracheal intubation in adult surgical patients undergoing general anaesthesia

Abstract

Introduction: McCoy laryngoscope and video laryngoscopes are being increasingly used as they offer advantages over the conventional laryngoscopes in airway management. The aim of this study is to compare and evaluate the efficacy of McCoy laryngoscope and TAScope in providing good glottic view and ease of intubation and observing the hemodynamic stress response. Materials and Methods: It is a randomised study including 60 patients aged 18-60 years with ASA grade I and II, divided equally in Group M and Group T, posted for elective surgery. Ease of intubation was evaluated by intubation difficulty score(IDS). Hemodynamic parameters, intubation time and airway trauma were compared in both the groups. Results: IDS TOTAL was higher in group M and was statistically significant (p<0.001). The mean time taken for intubation in group T was 46.08seconds and 26.53seconds in group M (p<0.001). There was a transient increase in pulse and blood pressure after laryngoscopy in both the groups but rise were less in group T. Less airway trauma was observed in group M as compared to group T. TAScope took more time compared to McCoy but it resulted in better first attempt intubation, provided more haemodynamic stability and less airway trauma as compared to McCoy.
