Background: Laparoscopic surgeries namely cholecystectomies, appendicectomies hernia repairs, urologic and minor gynaecological procedures like diagnostic hysterolaparoscopy (DHL) are common in routine medical practice. Tracheal intubation is considered ideal for airway management in laparoscopic surgeries as it provides safe glottic seal, adequate ventilation and protects against pulmonary aspiration even in the presence of raised airway pressures due to pneumo-peritoneum. Supraglottic airway devices (SGAs) are gaining popularity as alternative to endotracheal tubes (ETT) as a tool for airway management due to their positioning outside of the larynx making them less invasive as compared to ETT. Material & Methods: We used a newer Supraglottic device - Baska mask for airway maintenance in 114 patients undergoing laparoscopic surgeries and compared it with conventional ETT in a randomised, controlled clinical trial. Results: Median seal pressures were comparable with the two devices. The first time success rate for insertion and ease of insertion was higher with the Baska mask than that seen with the ETT (90% vs 70%) respectively, p < 0.001). There was a significant variation in heart rate and mean arterial pressure between the two groups at the time of insertion and removal of devices with ETT group showing a significant rise in both parameters at insertion and removal (p <0.05). The Baska mask proved easier and quicker to insert as compared to ETT. The mean insertion time for Baska mask being 12.2 2.1sec and for ETT 19.42.6 sec. Compared to ETT there were less complication rates with Baska mask such as laryngospasm or throat discomfort during post-op period. Conclusion: Baska mask is a useful and safe alternative to ETT in patients undergoing short (<1 hr) laparoscopic procedures and surgeries. As compared to ETT, Baska mask has advantages of ease of insertion and lesser complications.
