AbstractWe present a new intubation technique using an oral preformed tracheal tube passed through a laryngeal mask. Six patients (neonate to six months old) with craniofacial malformations of head and neck and scheduled for reconstructive plastic surgery are the basis of this report. An inhalation induction with increasing doses of halothane in oxygen while maintaining spontaneous ventilation was performed. Once an adequate anaesthetic depth was achieved, a direct laryngoscopy was performed. The epiglottis could not be seen in any of the patients. Anaesthesia was deepened in order to insert the laryngeal mask, size 1 or 2, with an oral preformed 3.5 or 4.0 tracheal tube inside it. Correct position of the mask was confirmed by capnography. The preformed tracheal tube was then advanced 1-2 cm. and its position in the trachea verified. The 15 mm connector was then removed, and an adult intubating stylet was attached to the end of the tracheal tube. The laryngeal mask was removed, holding the stylet and tube in place. Once the mask was removed, the stylet was disconnected, and the 15 mm connector reattached. Our experience was that this takes about 20 to 30 s. We recommended this technique in paediatric patients in which a difficult intubation is foreseen.
