- Clear tubing and convenient depth marks allow for easy identification of correct placement of the tube;
- Features an ergonomically shaped airway tube for firm and ergonomic grip during insertion;
- Equipped with a soft cuff that ensured a good seal and less permeable nitrous oxide.
It is advised that before insertion, one should deflate the cuff completely so that it is flat and free of wrinkles. To do this, simply press the cuff down onto a flat sterile surface while simultaneously deflating the cuff with a syringe.
There are many insertion techniques currently in use. One commonly used technique is the Pencil Insertion. The technique starts by assuming access from the patient’s head from above is feasible, and holding the airway tube like a flute, with three fingers placed above the junction of the cuff and the tube and the thumb on the vertical line on the airway tube. All this should be done while simultaneously placing your other hand under the patient’s head.
Then slowly and carefully insert the tip of the cuff pressing upwards against the hard palate and flatten the cuff against it. Look carefully into the mouth to verify that the tip of the cuff is flattened against the palate before proceeding.
Provided the tip of the cuff is placed correctly in the mouth opening, continue the movement by swinging the mask inward with a circular motion, pressing the contours of the hard and soft palate in the process, and slowly start advancing the equipment into the hypopharynx until a definite resistance is felt. Ensure that the motion of the placement is smooth.
- The use of a laryngeal mask may cause minor adverse effects such as sore throat and major adverse effects such as aspiration;
- Never use excessive force when using the equipment;
- Always check that the level of anesthesia is adequate before attempting insertion.
