Comparison of the Baska and I-gel supraglottic airway devices: a randomized controlled study

Abstract

BACKGROUND: Laryngeal masks are increasingly used in place of endotracheal intubation or face masks for maintaining the airway during surgery.OBJECTIVES: Compare the insertion time and other features of the Baska and I-gel masks in patients undergoing general anesthesia for urological surgery.DESIGN: Randomized-controlled, single-blind study.SETTINGS: Urology surgical operating rooms of a tertiary care hospital.SUBJECTS AND METHODS: We enrolled concomitant patients whose surgery was expected to last less than two hours. Following premedication and adequate relaxation, subjects were randomly allocated to the I-gel mask or the Baska mask. Computer-generated random numbers were used for randomization with sealed opaque envelopes for allocation concealment.MAIN OUTCOME MEASURES: The primary outcome measure of the study was the time required for laryngeal mask airway (LMA) insertion. Also, the number of device placement attempts, the number of postoperative signs and symptoms (cough, breath holding, laryngeal spasm, lip trauma, blood on the mask), and laryngopharyngeal morbidity scores at 1 and 24 hours postoperatively.SAMPLE SIZE: 211 met inclusion criteria, 200 participants completed the study.RESULTS: Compared to I-gel, the Baska mask required a longer time for insertion, and its airway pressure was higher. The median (minimum-maximum) duration of LMA insertion in the Baska and I-gel groups was 14 (6-25) and 7 (5-12) seconds, respectively (z=-10.934; P<.001). The mean (SD) airway pressures were significantly different between the two groups (15.8 [1.9] and 14.9 [1.7] cm/H2O for Baska and I-gel, respectively; t=3.668; P<.001). Seal pressure was not significantly different between the groups (0.08 [0.2] vs. 0.07 [0.2] cm/H2O in the Baska and I-gel groups, respectively, (t=1.35; P=.194).CONCLUSIONS: The Baska and I-gel masks are similar in most respects. Both have reasonably acceptable insertion times and can be used for selected surgical procedures.LIMITATIONS: The requirement for more vigorous training is a limitation of the Baska mask. Results could differ with patients younger than 18 years of age or obese patients.CONFLICT OF INTEREST: None.CLINICAL TRIAL REGISTRY: Not registered.

Influence of head and neck positions on oropharyngeal seal pressure with Baska mask® versus I-gel™; A randomised clinical study

“…in their study comparing Baska mask ® and I-gel™ where the median time taken for device insertion in I-gel™ group was less compared to Baska mask ® group ( P < 0.05). [ 20 21 ] The reason for this is that I-gel™ is less bulky, easy to handle, bears high stability, and becomes immediately operational after insertion as having preformed non-inflatable cuff.…”

Comparison of the Baska mask and the i-gel supraglottic airway devices in patients undergoing elective surgery

“…However, other parameters, such as insertion time, fibre-optic view of the glottis, the use of airway manipulation, heart rate, mean arterial pressure, PAP, lung compliance, and perioperative complications, were comparable [14]. A study by Kara et al showed that the Baska mask provided a significantly higher PAP than the i-gel (15.8 cm H 2 O ± 0.9 cm H 2 O and 14.9 cm H 2 O ± 1.7 cm H 2 O, respectively) [11], which was supported by our study. Even though our results showed that the i-gel was superior in some of the parameters, the margin of difference was actually not large.…”

“…Kara et al conducted a comparison study between the Baska mask and i-gel in 200 patients undergoing urologic surgery. The i-gel showed significantly shorter median insertion time than the Baska mask (7 s [5][6][7][8][9][10][11][12] and 14 s [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25], respectively). However, there were no significant differences in the other parameters (the number of device placement attempts, sealed pressure and the number of post-operative complications) [11].…”

Comparison of the LMA Protector and the Baska Mask in Retrograde Ureteroscopic Surgery: A Prospective Randomized Clinical Study

“…4 Insertion time of the Baska mask took 14 s in our study which was identical to previous literature that found 14-16 s insertion times for the Baska mask. 1,[5][6][7][8] Some other studies showed 21-24 s insertion times for the Baska mask. [9][10][11] This demonstrates that Baska mask insertion times can vary quite a bit.…”
