Pressor Response To Introduction Of Intubating Laryngeal Mask Airway (ILMA) And Intubation Through ILMA.

Background: Laryngoscopy followed by tracheal intubation is the commonest technique of securing airway. However, laryngoscopy time more than 15 seconds leads to exaggerated pressor response. It can also result into a cardiovascular catastrophe in vulnerable elderly patients. Materials and Methods: A prospective and randomised single centre study was conducted upon patients belonging to American Society of Anaesthesiologist (ASA) physical status I and II who were scheduled for elective surgery under general anaesthesia. Sixty (60) patients were randomly allocated to two groups (I & II) of 30 each by sealed envelope technique. In group I, conventional laryngoscopy and intubation was carried out and in group II, intubation was carried out using intubating laryngeal mask airway (ILMA), fastrach. Results: Haemodynamic parameters (heart rate and mean arterial blood pressure) were compared between the two groups. Two tailed independent t test was used for comparison of the parameters. Rise in heart rate (HR) and mean arterial pressure (MAP) was statistically significant at stage-2 in group I (p >0.001). Conclusion: ILMA insertion and intubation using it can be recommended for patients vulnerable to cardiovascular event. [ABSTRACT FROM AUTHOR]
