Background: Second-generation supraglottic airway devices (SADs) are used in routine cases or when encountered with a difficult airways. This study was done to compare the ease of blind endotracheal intubation using I-Gel versus the Blockbuster Laryngeal Mask Airway (LMA) in female patients posted for laparoscopic cholecystectomy under general anesthesia. Materials and methods: This study was a randomized, prospective, double-blind and controlled in which included Ninety, American Society of Anaesthesiologists (ASA) I-II and Mallampatti class (MMC) 3-4, female patients aged between 18-60 years and were divided into two groups. Each Group A and B had 45 patients, in whom blind endotracheal intubation was attempted through the I-Gel and Blockbuster LMA respectively after induction of anaesthesia. The time required for insertion, ease of insertion, number of attempts, maneuvers applied, and time for intubation, intubation success rates, intraoperative hemodynamic parameters during the procedure along with postoperative complications thereafter were documented and compared. Results: Time required for placement was less and ease of insertion better with Blockbuster LMA as compared to I-Gel. Duration for tracheal intubation was reduced and the overall rate of successful intubation was higher (96.9%) with Blockbuster LMA than I-Gel (80%). Fewer hemodynamic changes with minimal post-operative complications were seen with the Blockbuster LMA. Conclusion: It was concluded by the study that both I-Gel and Blockbuster LMA can be used as a channel for conducting endotracheal intubation, the overall success rate was higher with the Blockbuster LMA with minimal complications.
