USE OF MCCOY AND TRUVIEW LARYNGOSCOPE BLADES FOR INTUBATION IN PATIENTS WITH ANTICIPATED DIFFICULT AIRWAY WITH RESPECT TO EASE OF INTUBATION AND HAEMODYNAMIC RESPONSE
Journal Title: Journal of Evidence Based Medicine and Healthcare - Year 2017, Vol 4, Issue 35
Abstract
BACKGROUND The aim of this study is to compare the McCoy blade laryngoscope and TruView laryngoscope in patients with anticipated difficult tracheal intubation with respect to ease of intubation, haemodynamic stress response and incidence of complications. MATERIALS AND METHODS Out of 120 patients anticipated to have difficult intubation using the standard criteria of airway assessment preoperatively including modified Mallampati classification, mouth opening, neck extension, SLUX, Upper Lip Bite Test (ULBT) and thyromental distance. The patients are randomised into 2 groups using computer generated randomisation chart. Group T (n=60)- intubation with TruView blade and Group M (n=60)- intubation with McCoy blade. The two groups were studied using Chi-square tests. p<0.05 was considered statistically significant. RESULTS Overall, there was an improvement in the Cormack-Lehane grade (CL grade) after using either McCoy or TruView laryngoscopes. The number of patients with CL grade I (85.0%) in TruView group is significantly more as compared to grade I CL in McCoy group (50%), p=0.039, 13.3% of cases required ELM in the McCoy group, which was significantly more as compared to 3.3% cases in the TruView group. Mean total time taken for endotracheal intubation was 33.73 secs. in McCoy group, which was significantly less as compared to 64.03 secs. in TruView group. When compared between the groups, the increase in HR over the baseline was more in the McCoy group than the TruView group. CONCLUSION TruView laryngoscope provided excellent glottic view and showed better haemodynamic stability as compared to McCoy laryngoscope.
