Background: Many supraglottic airway devices are utilized instead of intubation. In this single-blind, interventional prospective trial, we compared I-Gel, LMA Supreme, and Ambu AuraGain in laparoscopic procedures performed under general anaesthesia. The aim and objectives were to compare the time and number of attempts required for SGA, Nasogastric tube insertion, the intra-operative and post-operative SGA complications and the Oropharyngeal seal pressure. Material and Methods: Following institutional review board approval and written informed consent. A comparative, single-blind, interventional prospective study was conducted. Patients with American Society of Anesthesiologists physical status 1 and 2 who met the qualifying requirements were randomly assigned to one of three groups: Group A I-Gel (n=30), Group B LMA Supreme (n=30), or Group C Ambu AuraGain (n=30). The major purpose was to compare the duration and number of attempts required for SGA insertions. Results: Demographic data were not different across the groups. Group A I-Gel had a significantly lower SAD insertion time (19.93±1.91 s) compared to Group B LMA Supreme (25.63±1.75) and Group C Ambu AuraGain (29.77±2.47). One number of attempt was significantly (p=0.01) lower in Ambu AuraGain (43.3%) than LMA Supreme (50%) and I-Gel (80%) group. The pairwise comparison revealed that there was significant difference in number of attempts required for LMA insertion between Ambu AuraGain& I-Gel (p=0.006) and LMA Supreme & I-Gel (p=0.03). The OLP forGroup C (30.83±2.10 cm H2O) was greater than Group B (26.10±1.66 cm H2O) and Group A (22.70±1.44 cm H2O). There was no significant difference (p>0.05) in the number of attempts needed for nasogastric tube insertion between the groups. There was no significant difference (p>0.05) in perioperative and postoperative complications within or between groups. Conclusion: Ambu AuraGain has higher oropharyngeal seal pressures than I-gel and Supreme LMA, as well as comparable hemodynamic stability and postoperative outcomes, making it a better SAD for laproscopic procedures than I-gel and Supreme LMA. I-Gel's shorter insertion time makes it better suited for resuscitation and emergencies. |
