To Compare the Haemodynamic Response to Laryngoscopy and Tracheal Intubation Using the Standard Macintosh Laryngoscope Versus Videolaryngoscope Among Healthy Adult Individuals Receiving General Anaesthesia for Elective Surgery

Abstract

BACKGROUND Laryngoscopy and endotracheal intubation are associated with various undesirable effects. The more common response to airway manipulation is hypertension (HTN) and tachycardia mediated by the cardioaccelerator nerves and sympathetic chain ganglia. Numerous efforts have been made by anaesthesiologists to obtund these untoward reflexes by the use of various measures such as by using drugs or by using different methods of intubation. MATERIALS AND METHODS100 patients of either sex of ASA grade I and II and Mallampati grade I and II of age 18 -60 years were included in the study. Patients < 18 years of age and > 60 years of age and Mallampati grade III and IV were excluded from the study. A standard anaesthesia technique was used in all the patients. Both groups were matched demographically. Haemodynamic variables at baseline were also comparable.
