Background:
New supraglottic devices are being introduced into
the market with various claims regarding their safety
and efficacy.
Objectives:
To compare number of attempts at insertion,
oropharyngeal leak pressure, associated trauma,
fiberoptic assessment of proper placement and the
hemodynamic changes with use of Baska mask and I
Gel.
Material and methods:
The present study was a prospective, randomized,
study. Sixty patients undergoing surgeries under
general anesthesia were included. Patients were divided
into two equal groups and received anesthesia following
a standardized protocol. In Group B patients Baska
mask was used whereas I-Gel was used in Group I to
provide anesthesia. Statistical analysis was done using
Chi-square test and Independent sample t-test as
applicable.
Results:
Time taken for securing airway and number of
attempts taken were significantly higher in Group B.
Incidence of trauma was comparable. Oropharyngeal
leak pressure (OLP) was significantly higher in Group
B (36.33±5.68 vs 25±5.79), percentage of patients with
Grade I-III score on fiberoptic assessment was also
significantly higher in Group B. Both groups had
comparable heart rate (HR) and mean arterial pressure
(MAP) before induction, after induction and at 10 min
after securing airway. At 1, 3 and 5 minutes after
securing airway Group B had significantly higher HR
and MAP.
Conclusion:
I Gel insertion was quicker, less traumatic,
required fewer attempts and was associated with
blunted hemodynamic responses. But OLP was
significantly higher with better fiberoptic assessment
score of proper placement with use of Baska mask.
