To the Editor:-It is occasionally difficult to ventilate a tracheotomized patient. In such a patient, controlled ventilation through a face mask is difficult. Some patients can easily tolerate topical anesthesia and awake insertion of an endotracheal tube through a tracheotomy orifice, followed by the anesthesia. However, for those who cannot, deep anesthesia and muscle relaxation before tube placement may be preferable.
In such a situation, ventilation using a small laryngeal mask fitted over a stoma has proven to be a reasonable solution (Figure 1). With this method, we can easily ventilate a patient and control the depth of anesthesia.
Ventilation via a tracheostomy using a pediatric mask over the stoma has been reported previously. Unfortunately, in some cases, it is difficult to fit a pediatric mask because of a hollow between clavicles, the sternum, and sternocleidomastoid muscles. In such cases, the use of a small laryngeal mask airway may be of value.
