Feature:
1. Easy insertion: LMAs are designed for easy and rapid insertion, reducing the risk of complications.
2. Reliable performance: LMAs provide a secure and stable airway, ensuring reliable ventilation and oxygenation.
3. High seal pressure: LMAs create a high seal pressure, preventing air leaks and ensuring effective ventilation.
4. Low risk of trauma: LMAs are designed to reduce the risk of trauma to the patient's airway and surrounding tissues.
5. Flexible and adaptable: LMAs are available in various sizes and are adaptable to different patient sizes and ages.
6. Quick and easy removal: LMAs can be quickly and easily removed, reducing the risk of complications during extubation.
7. Reduced risk of aspiration: LMAs reduce the risk of aspiration, as they sit above the glottis and prevent stomach contents from entering the lungs.
8. Improved patient comfort: LMAs can reduce patient discomfort and anxiety, as they do not require insertion through the mouth or nose.
9. Easy suctioning: LMAs allow for easy suctioning of secretions and debris from the airway.
10. Compatible with various ventilators: LMAs are compatible with various ventilators and anesthesia machines, making them versatile and convenient.
1. The i-gel features a gastric channel (except in size 1) that provides several benefits. This channel serves as an early warning system for regurgitation, allowing for prompt intervention. Additionally, it enables the passage of a nasogastric tube to empty stomach contents and facilitates venting, ensuring a safer and more efficient airway management experience.
2. Integral bite block prevents airway occlusion, ensuring a secure airway.
3. Buccal cavity stabilizer enables easy insertion and prevents rotation.
4. Epiglottic rest prevents downfolding and airway obstruction.
5. Soft, non-inflatable cuff for easy insertion and reduced trauma.
6. The tip of the gastric channel.
Advantages:
-
Easy Insertion: Easy and atraumatic to insert, with minimal somatic and autonomic responses.
-
Effective Ventilation: An effective method of ventilation.
-
Easier Placement: Easier placement by inexperienced personnel.
-
Improved Oxygen Saturation: Improved oxygen saturation.
-
Less Hand Fatigue: Less hand fatigue.
-
Improved Operating Conditions: Improved operating conditions.
Application Scenarios:
-
Anesthesiology: Useful airway device for most adult and pediatric patients in anesthesiology.
-
Emergency Medicine: Used in emergency medicine as a lifesaving device.
-
Difficult Airways: Used in patients with difficult airways.
