A COMPARATIVE STUDY OF PRESSOR RESPONSE FOLLOWING LARYNGOSCOPY AND TRACHEAL INTUBATION VERSUS INTRODUCTION OF INTUBATING LARYNGEAL MASK AIRWAY AND INTUBATION THROUGH IT

Background: Though laryngoscopy and tracheal intubation is the commonest technique of securing airway, laryngoscopy exceeding 15 seconds is associated with exaggerated pressor response. It can lead to a cardiovascular catastrophe especially in elderly patients Methods: A prospective randomised study was conducted in patients belonging to American Society of Anaesthesiologist (ASA) physical status I and II scheduled for elective surgery under general anaesthesia. Sixty patients were randomly divided into two groups of 30 each. In group I laryngoscopy and intubation was performed and in group II intubation was performed through intubating laryngeal mask airway (ILMA), fastrach Results: Haemodynamic parameters were compared between the two groups using two tailed independent t test. Surge in heart rate (HR) and mean arterial pressure (MAP) was statistically signicant in group I (p > 0.001) Conclusion: The technique of ILMA insertion and intubation can be recommended for patients vulnerable to cardiovascular event.
