Comparison of Baska Mask Versus I-Gel in Short Gynaecological Laparoscopic Surgeries Under General Anaesthesia in Adult Female: A Randomized Interventional Study

Abstract

Background: Various newer generations of Supraglottic Airway Devices (SAD) with improved designs and performance are available for use by anaesthesiologist. We conducted the present study to compare 3^rd generation SAD Baska Mask with 2^nd generation SAD I-gel with the aim of comparing their clinical performance in terms of insertion parameters and oropharyngeal leak pressure in short laparoscopic gynaecological surgeries in adult females.
Methods: 80 adult female patients were randomly allocated to either Baska Mask (n=40) or I-gel (n=40) groups. Insertion characteristics that included number of attempts, mean insertion time and manipulation frequency were recorded and compared. Oropharyngeal leak pressure was measured just after insertion of device and after 5 min of creating pneumoperitoneum in both devices and were compared.
Results: Baska Mask insertion was successfully achieved in first attempt in 38/40 patients in Baska group vs 35/40 patients in I-gel group. Mean oropharyngeal leak pressure (OLP) in Baska Mask versus I-gel just after insertion was (29.24±4.20cm H20 vs 26.33±2.51cm H2O, P=0.003) whereas it was (29.42±2.70 vs 26.18±2.54 cm H2O) after 5 min of creating pneumoperitoneum. Both groups were comparable in terms of removal characteristics and postoperative laryngopharyngeal airway morbidities.
Conclusion: Baska Mask provided more effective ventilation in terms of greater oropharyngeal leak pressure as compared to I-gel. However Baska Mask was more difficult to insert and the incidence of postoperative laryngopharyngeal morbidity was higher in case of Baska Mask.
