We compared hemodynamic response with ILMA and I-gel insertion during general anaesthesia. Materials and Methods: The study was carried out as a prospective, randomized, blinded clinical study among 70 patients, divided in two equal groups 35 each, who underwent different surgical procedures under general anesthesia. After induction of anaesthesia, Supraglottic airway device was inserted in both groups, tracheal intubation was attempted through the ILMA. HR, SBP, DBP, ST-T segment changes and SPO 2 values were recorded before insertion of airway device, at one minute and at five minute after insertion in each case. Results: There was no change in HR at 1 min in I-gel group, while in ILMA group, it increased. Rise in SBP at 1 min after insertion of supra-glottic airway device was observed in both groups, but at 5 min rise was insignificant in I-GEL group and significant in ILMA group. When both groups were compared significant difference (P<0.05) was observed. Rise in DBP in I-GEL group was insignificant but in ILMA group, rise was significant. When both groups were compared significant difference (P<0.05) was observed in HR and BP. Saturation did not change in both groups and also no change in ST-T segment was observed. Conclusion: We conclude that insertion of I-gel is accompanied by minimal cardiovascular responses than those associated with intubation through intubating laryngeal mask airway (ILMA), so it is recommended for patient where a minimal pressure response to airway manipulation is desired. Key Words – Tracheal intubation, supraglottic device, cardiovascular responses INTRODUCTION Laryngoscopy and tracheal intubation are required to control and maintain a safe airway during anesthesia. The procedure violates the patient’s airway reflexes and predictably leads to hypertension and tachycardia which may have detrimental effects on the other organ systems. Haemodynamic stability is an integral and essential goal of any anaesthetic management plan. Hypertensive patients have increased activity of the sympathetic nervous system and may exhibit an exaggerated hemodynamic response to the induction of anesthesia compared with normotensive patients. Marked increase in catecholamine concentration and in the sensitivity of
