Background and Aims: Supraglottic device can provide adequate ventilation for laparoscopic surgeries. This study was aimed to compare Proseal Laryngeal Mask Airway and IGel as airway device in laparoscopic hernioplasty. Methods: This was a prospective randomised study, conducted on 60 American Society of Anaesthesiology III adult patients posted for laparoscopic hernioplasty. Anaesthesia was induced with propofol and rocuronium. PLMA or IGel were introduced and fixed and Ryle’s tube was inserted. The attempts, ease of insertion, quality of airway sealing, haemodynamic changes, oxygenation, ventilation, respiratory mechanics and postoperative adverse event were noted. Statistical analysis was done with EPI 2000 software and
ease of insertion was the primary outcome variable. Results: Success rate of IGel insertion was 100% and that of PLMA was 96.67%. IGel was inserted at first attempt in 96.67% patients but for PLMA it was possible in 73.34% patients. Ease of insertion was more with IGel (score 393.33%) as compared to PLMA (score 3 70%). Difference between two device was statistically not significant in quality of airway sealing, haemodynamic parameters, attempts of Ryle’s tube insertion, oxygenation and ventilation (p>0.05). After capnoperitoneum, the peak airway pressure was 19±3.47 cmH2O, 21.03±3.77 cmH2O in IGel and PLMA group respectively. Insignificant adverse event were noted in both groups. Conclusion: Both IGel and PLMA can be used as airway
device in laparoscopic hernioplasty. Insertion of PLMA is more difficult than IGel but it provides effective ventilation similar to IGel, with minimum increase in peak airway pressure as compared to IGel.
