“Comparative Study of Laryngoscope View And Intubation Response To Laryngoscopy Using Mccoy And Macintosh Blades”
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2017, Vol 16, Issue 10
Abstract
Background and objectives: The objects of the study were to compare the laryngoscopic view and the hemodynamic changes by using flex tip McCoy laryngoscope with Macintosh laryngoscope.Observations and results:The mean rise in heart rate from a pre-induction value of 72.74 ± 0.1976 to 97.68 ± 0.2892 Beats per Minute (bpm) was noted in group Macintosh, while in group Mc’Coy the mean rise in heart rate was observed from 72.64 ± 0.1995 to 86.10 ± 0.2559 bpm. The mean rise in SBP from the pre-induction value from 113.5 ± 0.3490 to 145.3 ± 0.3366 mm of Hg was noted in group Macintosh, while in group Mc coy the mean rise in SBP was observed from 112.9 ± 0.2686 to 127.6 ± 0.1639 mm of Hg. Laryngeal view comparison: All patients in both groups were of Mallampati 1 and 2.patients intubated with Macintosh blade; it was found that 18 out of 50 patients were of Cormack and Lehane grade II.In patients intubated with McCoy blade, it was found that only 2 out of 50 patients were of Cormack and Lehane grade II.Conclusion:McCoy laryngoscope blade is useful in reducing the stress response to laryngoscopy when compared to Macintosh laryngoscope blade andMcCoy blade improves laryngoscopic view when compared to Macintosh blade.
