Comparison of the Stress Response, Laryngoscopic View and External Manipulation During Laryngoscopy and Intubation Using Mancintosh Versus Flexitip (Trupti) Blade
Journal Title: International Journal of Contemporary Medical Research - Year 2018, Vol 5, Issue 2
Abstract
Introduction: laryngoscopy and intubation is known to have profound cardiovascular effects like a pressure response and tachycardia associated with increase in catecholamine concentrations. The hinged blade tip (MacCoy) laryngoscope blade allows elevation of epiglottis with exertion of lesser force and hence reducing stress response.This laryngoscope blade is also found to be useful in improving laryngeal view in difficult airway. Study aimed to compare flexitip (Trupti) blade with standard Macintosh blade during laryngoscope and intubation with regard to Heart rate, Blood pressure and laryngoscopic view. Material and Methods: We studied 100 patients, with 50 each in Group 1 and Group 2, of age 18 - 60 years, ASA 1 and 2 in elective surgery under general anaesthesia with endotracheal intubations.Arterial pressure and heart rate were recorded at baseline preoperative and after sedation, later on after intubation till the end of the surgery and laryngeal view also assessed. Data within each group were analysed using repeated measured analysis of varience and both the groups using student’s ‘t’ test Results: In our study,there was significant reduction (p = 0.0202) in stress response i.e. heart rate and blood pressure with the use of flexitip laryngoscope blade. Also there was reduction in requirement of number of attempts, external manipulations with flexitip blade though it was not statistically significant. Conclusion: To avoid stress response to laryngoscopy and further complications, use of flexitip (Trupti) blade is a good choice, also there were improvement in laryngoscopic view, requirement of attempts and external manipulations.
