BACKGROUND Supraglottic airway devices may be used in hospitals for low-risk patients undergoing elective surgery, in spontaneous or positive pressure ventilation, for more complex patients and operations, for difficult airway management, for airway rescue, out of hospital use by less experienced or novice users, and during cardiopulmonary resuscitation. AIM OF STUDY To evaluate and compare I-Gel with Laryngeal mask airway for haemodynamic responses, ease of insertion and post extubation complications in anaesthetised patients. MATERIALS AND METHODS The study design was randomized and controlled. The patients were divided into 2 groups of 25 each with the help of computer generated random allocation. All patients were of ASA I physical status. Patients in Group I were intubated with Classic LMA and Group II with I-Gel. Following successful placement-the pulse rate, systolic blood pressure, diastolic blood pressure, end tidal CO2 and SpO2 were noted at insertion, at 1 min, 3 min and 5 min after insertion. The ease of insertion, the number of attempts taken for successful insertion, the time taken for insertion and presence or absence of residual air leak were noted. RESULTS Patients who were intubated with LMA had statistically significant high PONV, otherwise both the devices are statistically similar in all other parameters monitored. CONCLUSION In conclusion, it can be said that the I-Gel is inserted rapidly, and has lesser incidence of nausea and vomiting than the LMA
