Comparison between the Baska Mask^® and I-Gel for Minor Surgical Procedures Under General Anaesthesia

Area of Science:

• Anesthesiology
• Medical Devices
• Airway Management

Background:

• Minor surgical procedures under general anesthesia necessitate a secure airway without muscle relaxants.
• Supraglottic airway devices are commonly employed for airway management in such cases.

Purpose of the Study:

• To compare the Baska mask and I-gel, two supraglottic airway devices.
• Evaluate first-time insertion success rate, insertion time, sealing pressure, and complications.

Main Methods:

• A randomized, single-blinded study involving 50 ASA physical status I and II female patients (aged 18-40).
• Patients were allocated to either the Baska mask group (n=25) or the I-gel group (n=25).
• Key metrics measured included first-time success rate, mean insertion time, and sealing pressure.

Main Results:

• First-time insertion success rates were comparable: 88% for Baska mask vs. 92% for I-gel (p=0.585).
• Mean insertion times were also similar: 14.9±6.2 s for Baska mask vs. 14.7±4.4 s for I-gel (p=0.877).
• The Baska mask demonstrated a significantly higher mean sealing pressure (28.9±3.5 cmH2O) compared to the I-gel (25.9±2.5 cmH2O) (p=0.001).

Conclusions:

• The Baska mask and I-gel exhibit comparable first-time insertion success rates and insertion times.
• The Baska mask offers a statistically significant advantage in mean sealing pressure.
• Complication rates were similar between the two devices.
