Abstract :

BACKGROUND AND OBJECTIVE: Macintosh laryngoscope is one of the gold standard instrument used for tracheal intubation TruViewEVO2 blade incorporates a non–magnifying optic port with an anterior fraction of 42 ? which enable a better field for intubation. The purpose of this study was to evaluate the TruView laryngoscope in comparison to Macintosh laryngoscope with regard to cardiovascular response and laryngoscopic view. MATERIALS AND METHODS: 200 Adult patients(20–60yrs) with American Society of Anaesthesiologistsgrade I and II, Mallampati grade I and II posted for surgery under general anaesthesia at JSS Hospital, Mysore divided into two groups of 100 each. Laryngoscopic view and Hemodynamic response were assessed with statistical analysis. RESULTS In group T, 65 (65%) patients had Cormack and LehanegradingI, 33 (33%) patients had Cormack and Lehane grading II and 2 (2%) patients had Cormack and Lehane grading III. In group M, 42 (42%) patients had Cormack and Lehane grading I and 57 (57%) patients had Cormack and Lehane grading II and 1(1%) patient had Cormack and Lehane grading III The differences in the Cormack and Lehane between the two groups were statistically highly significant (p = 0.003).Group T mean heart rate increased from 85.540�14.67866 beats per minute prior to intubation to 94.5200�15.08259 beats per minute after intubation and mean arterial pressure increased from 92.7850�12.39260 mmHg prior to intubation to 101.2550�13.19825 mmHg after intubation. In Group M, mean heart rate increased from 84.7900�7.99153 bpm prior to intubation to 103.6100�9.30721 bpm after intubation and mean arterial pressure increased from 91.7070�8.08478mmHg prior to intubation to 97.1410�7.71946 mmHg after intubation(p=0.000). CONCLUSION TruView laryngoscope provides a better exposure of the glottis when compared to Macintosh laryngoscope while triggering minimum haemodynamic response to endotracheal intubation
