Usefulness of Light Wand-guided Insertion of Flexible Reinforced Laryngeal Mask Airway
Usefulness of Light Wand-guided Insertion of Flexible Reinforced Laryngeal Mask Airway: Comparison With Conventional Blind-insertion
Flexible LMA (Laryngeal mask airway) is very useful for variable situation but it is hard to insert in correct position because of it's flexible structure. Especially in classical way of manual LMA insertion, when the index finger could not guide the flexible LMA to the optimal position, we could not guarantee the correct position of the LMA. Therefore several studies have been investigated to improve this.
The light wand is a kind of stylet which have a light on the tip. Recently some studies demonstrated the usefulness of the light wand which could be used for indicating correct position of the LMA. We hypothesised there will be two advantages if the light wand is used as a stylet of the flexible LMA. First the stylet could support the mildness of the flexible LMA, and second the lightness could confirm the correct position of the flexible LMA.

|
Ingen indgriben: Control group
The flexible LMA is inserted using "index finger technique"

Aktiv komparator: Light wand group
The flexible LMA is inserted using light wand as a stylet
|
The light wand is used as a stylet of the flexible LMA.
When the investigator inserts the flexible LMA in "light wand group", the correct position of the LMA is confirmed by the light.

Oropharyngeal leak pressure
Tidsramme: 5 minutes after LMA is inserted
|
The oropharyngeal leak pressure is measured by the pressure which the investigator could detect the audible sound by stethoscope on patient's cheek during the exhaust valve is closed and the fresh gas is allowed to flow into the lungs at 3 liters per minute.
