Summary

Our study aimed to compare the manual placement, direct laryngoscopy and video laryngoscopy assisted placement techniques of LMA Proseal, a new generation laryngeal mask (LMA), and to find an effective placement technique that does not allow airway leakage in one go.

Detailed description

LMA is an airway device frequently used in pediatric anesthesia. It is preferred for short interventions because it is less invasive compared to intubation. However, problems such as not being fully seated, slipping, and leakage can be encountered during placement. Multiple attempts after unsuccessful placement may cause undesirable results such as edema and sore throat. The aim in this study is to reveal the most accurate placement technique and to transfer this method to clinical applications. Our research is a prospective, randomized controlled method study. Patients will be divided into 3 groups. Group 1:(Standard technique) Group 2:(Placement with direct laryngoscopy) Group 3:(Placement with the aid of video laryngoscopy) After LMA Proseal placement, airway sealing pressures will be measured with appropriate technique. Airway tightness pressure measurement will be made with the technique accepted in the literature through the sensors in the anesthesia machine.

Conditions

• Anesthesia
• Airway

Interventions

Type	Name	Description
PROCEDURE	Group 1	The LMA Proseal will be inserted directly by hand, without the use of any laryngoscope, as recommended in the instruction manual. The cuff will be gently guided along the hard palate where it is pushed into the hypopharynx and increased resistance is felt, and the cuff will be placed towards the hypopharynx.
PROCEDURE	Group 2	Appropriately sized laryngoscope blade will be used and after the location of the epiglottis is determined, the tongue and epiglottis will be lifted forward. Then, LMA Proseal will be placed at the point where resistance is felt at a level where the proximal edge of the mask can be seen.
PROCEDURE	Group 3	After the video laryngoscope is placed with an appropriately sized blade, the location of the epiglottis and vocal cords will be determined and the LMA Proseal will be placed at the point where slight resistance is encountered after the epiglottis is lifted. proximal aspect of LMA
