Emergency use of a size 1 laryngeal mask airway in a ventilated neonate with an undiagnosed type IV laryngotracheo-oesophageal cleft.

The perioperative management of a neonate with a type IV laryngotracheo-oesophageal cleft and exomphalos major is described. Following an otherwise uncomplicated exomphalos repair, this baby became increasingly and inexplicably difficult to ventilate through an endotracheal tube. The emergency use of a laryngeal mask airway as a rescue maneuver allowed positive pressure ventilation, and subsequent diagnosis of the airway abnormality. The difficulties in management of the two co-existing conditions are discussed.
