Background: Intubating laryngeal mask airway is used for blind endotracheal intubation and is also considered to cause less stress response as compared to intubation following conventional laryngoscope. Aim: To determine whether Intubating laryngeal mask airway or Laryngoscopy cause minimal stress response following intubation in normotensive as well as in hypertensive patients. Methods: This was a randomized control trial study. Two control groups were formed. They were age 18 to 65 years belonging to ASA I and II. Group, I patients was intubated with Macintosh laryngoscope and group II were intubated with the help of ILMA. Vitals monitored were Heart rate, Systolic blood pressure, diastolic blood pressure and mean arterial pressure at baseline, before induction, after induction, after intubation at 1, 3 and 5 minutes intervals. Pharyngolaryngeal morbidity was also recorded and followed for 24 hours following procedures. Results were analyzed using Mann-Whitney Test and the Independent t-test. The qualitative variables were analyzed using the Chi-Square test/Fisher’s Exact test. Result: Demographics, as well as vital parameters, showed no significant differences between the two groups. The decrease in stress response was seen in normotensive patients only in group II but not in hypertensive patients. Conclusion: Intubating laryngeal mask airway did not help in blunting the stress response when compared with Macintosh laryngoscope in hypertensive patients but a decrease in stress response was seen in normotensive patients at 3 minutes after intubation. Though it can be used as an alternative method for intubation. |
