Abstract
Background: The response to stress induced through laryngoscopy and tracheal intubation significantly affects circulatory parameters, leading to issues like tachycardia and hypertension. Aim: To investigate the influence of laryngoscope type on hemodynamic responses and critical aspects of the intubation procedure.
Methods: ThisProspective, Randomized and controlled study was conducted in the Department of Anesthesiology, Maharishi Markandeshwar Institute of Medical Sciences and Research Mullana Ambala, after obtaining hospital ethical committee approval. Patient's history and clinical examination were reviewed in detail. The Modified MP Score was used to examine airwayconditions. The intubation method, whether with a Macintosh or C-MAC blade, was chosen at random. This complete strategy ensured that anaesthetic was administered in a controlled and safe manner throughout the surgical process. Key physiological parameters to ensure precise anesthesia management and patient safety were employed. This included continuous tracking of HR, SBP and DSB, MAP, RR, and OS. Monitoring occurred at specific time intervals: pre-induction baseline, before laryngoscopy, during laryngoscopy, during intubation (In), and post intubation at 1, 2, 3, 4, and 5 minutes.
Results:There were not any significant variations in age, height, or weight between the two subgroups. The mean surgical length was likewise comparable between the two groups with a p = 0.020. The distinction of ASA scoring in both sets proved to be insignificant. Significant differences in heart rate between Group A and Group B across different stages of intubation were observed. Before intubation, Group A had a higher mean heart rate compared to Group B, and this difference was statistically significant (p = 0.001). In both groups, blood flow responses to the two procedures utilizing MAC and C-MAC were comparable for those during surgical anesthesia with acceptable amounts of sedation.
Conclusion: We conclude that, hemodynamic responses during laryngoscopy and intubation using Macintosh or C-MAC laryngoscope are same. These findings suggest that both laryngoscopes are equally effective in clinical practice, ensuring similar patient outcomes and hemodynamic stability throughout intubation and recovery periods.
