Till date, tracheal intubation is considered to be the gold standard for providing seal in laparoscopic surgeries but over a period of time supraglottic airway devices ( like I-gel and  Proseal Laryngeal Mask Airway) have evolved which overcome the disadvantages of endotracheal tube.A comparison of I-gel, Proseal Laryngeal Mask Airway and Endotracheal Tube in laparoscopic surgeries by Rukhsana Najeeb et al in 2015 shows that I-gel was easier to insert with higher success rate in first attempt (92.5%) than Proseal Laryngeal Mask Airway (85%) and endotracheal tube (82.5%).⁽³⁾ Till date, there are limited studies which have evaluated and compared I-gel, Proseal Laryngeal Mask Airway and Endotracheal tube together for features like leak volume, leak fraction and leak pressure. We will conduct this study to compare supraglottic airway devices like I-gel^TM and Proseal Laryngeal Mask Airway with standard endotracheal tube for the parameters that include number of attempts taken for insertion, hemodynamic changes, ventilation parameters, leak volume, leak fraction, leak pressure and postoperative complications during general anaesthesia, in healthy adult patients undergoing laparoscopic surgeries. First 90 patients meeting the inclusion criteria will be enrolled in the study. Group E (n=30) receiving endotracheal tube, Group P (n=30) receiving Proseal Laryngeal Mask Airway and Group I (n=30) receiving I-gel for airway maintenance. Patients will be assessed for insertion characteristics of airway devices (insertion at first attempt with no resistance; insertion at second attempt; insertion at third attempt and failed insertion - insertion not possible), hemodynamic responses (heart rate and blood pressure), ventilation parameters, leak pressure, leak volume, intraoperative and postoperative complications. Statistically significant (p<0.05) increase in heart rate and the mean blood pressure will be observed immediately after insertion, persisted till 5 minutes after intubation and during the time of extubation. We will observe incidence of blood staining of the device, sore throat and dysphasia, coughing, laryngospasm, gastric insufflation, regurgitation, aspiration, billous secretion, stridor, hoarseness of voice, injuries (to lip, teeth, and gum), and dysphonia during perioperative period.
