Efficacy of Laryngoscopy and Haemodynamic Response to Endotracheal Intubation: A Comparitive Study between Airtraq Optical Laryngoscope and Macintosh Laryngoscope
Journal Title: Indian Journal of Anesthesia and Analgesia - Year 2017, Vol 4, Issue 2
Abstract
Background: Laryngoscopy and endotracheal intubation plays a crucial role in administering general anaesthesia. Laryngoscopes ranging from simple rigid scope with light bulb to complex fiberoptic video devices have been developed to ease the process of laryngoscopy and intubation. Objective: This study was conducted to compare the efficacy of laryngoscopy and the haemodynamic response to endotracheal intubation between Airtraq and Macintosh laryngoscopes. Methodology: One hundred patients of either sex, in the age group of 20 – 60 years under ASA grade I and II with Mallampati grading I and II posted for elective surgery under general anaesthesia were randomly divided into two groups (n = 50). Induction of anaesthesia was standardized. The efficacy of laryngoscopy was comparared according to Cormack and Lehane grading and haemodynamic response to endotracheal intubation were compared. Results: In group A (Airtraq), all 50 (100%) patients had Cormack and Lehane grading I and in group M (Macintosh), 33 (66%) patients had Cormack and Lehane grading I and 17 (36%) patients had Cormack and Lehane grading II ( p = 0.000). In Group A, mean heart rate increased from 83.54 ± 10.19 bpm prior to intubation to 90.08 ± 9.98 bpm after intubation and mean arterial pressure increased from 91.06 ± 8.16 mmHg prior to intubation to 95.30 ± 8.40 mmHg after intubation. In Group M, mean heart rate increased from 80.94 ± 6.71 bpm prior to intubation to 103.30 ± 7.86 bpm after intubation and mean arterial pressure increased from 91.80 ± 7.70 mmHg prior to intubation to 114.20 ± 6.69 mmHg after intubation (p = 0.000). Conclusion: Airtraq optical laryngoscope provides a better exposure of the glottis when compared to Macintosh laryngoscope while triggering minimum haemodynamic response to endotracheal intubation.
