Abstract

Introduction: Direct laryngoscopy & endotracheal intubation induces cardiovascular stress response which in turn causes tachycardia & hypertension. This is particularly harmful in hypertensive patients. In this study we compared the hemodynamic response in direct & video laryngoscopy in hypertensive patients. Materials and Methods: In this study 98 controlled hypertensive patients ASA physical status 1 & 2
scheduled for elective surgery under general anesthesia requiring endotracheal intubation. Patients were divided in to 2 groups with 49 patients in each group. Group A: underwent endotracheal intubation with direct laryngoscopy. Group B: video laryngoscopy was used for the patients in this group. Both groups were assessed for Hemodynamic responses during laryngoscopy & intubation. Statistical analysis: This was done using mean, standard deviation, ANOVA for repeated measures followed by Bonferroni test and ‘t‘ test. Result: Video laryngoscopy showed less variations in hemodynamic responses compared to direct laryngoscopy, whereas time taken for video laryngoscopy was longer than that for direct laryngoscopy. Conclusion: Video laryngoscopy is better than direct laryngoscopy to reduce stress responses during endotracheal intubation.
