Introduction: Supraglottic Airway Devices (SADs) have established a role in both routine as well as emergency airway management of difficult airways in both children and adults. But anaesthesiologist may need to secure the airway by inserting an Endotracheal Tube (ETT) at any time.
Aim: To evaluate success rate of Baska mask and Intubating Laryngeal Mask Airway (ILMA) for ETT insertion through them by conducting a prospective and randomised study.
Materials and Methods: The randomised clinical study was conducted in 60 American Society of Anaesthesiologists (ASA) status I-II patients scheduled for elective surgical procedures requiring endotracheal intubation through either Baska mask or ILMA. In both the groups, standard induction and insertion technique of SAD was used. Reinforced ETT was used in the first attempt and Polyvinyl Chloride (PVC) ETT in the second attempt for intubation through both SADs. The total time for intubation, number of attempts taken to insert the SAD and ETT through it, haemodynamic response and adverse events were studied. Data was analysed using Statistical Package for the Social Science (SPSS) version 21.0.
Results: Patients in both the groups were comparable demographically with respect to sex, as a status, age and weight. Successful intubation was achieved in 33.3% (n=10/30) on first attempt through Baska mask compared to 86.7% in ILMA (n=26/30) (p=0.001). The overall intubation success rate was also lower with Baska group (56.7%; n=20/30) compared to ILMA (100%; n=30/30) (p<0.001). The haemodynamic parameters during intubation were also significantly higher in the Baska group as compared to the ILMA group. There were no differences in the other secondary outcomes.
Conclusion: The first pass and overall success rate of intubation through the Baska mask were inferior to those of ILMA.
