Differential lung ventilation in an infant using LMA and a long tracheal tube.
This is a case report of differential lung ventilation in an infant using a conventional laryngeal mask airway (LMATM) and a commercially available longer paediatric tracheal tube. This 2-month-old infant had her left-sided congenital diaphragmatic hernia repaired on the sixth day of her life, and had been mechanically ventilated. The right middle lobe became grossly emphysematous and herniated into the left side of the chest, and the right lower lobe became totally atelectatic. A right middle lobe lobectomy was planned. To avoid hyperinflating the right middle lobe, and to expand the right lower lobe without providing a high airway pressure on the left lung, the dependent lung (i.e. left lung) was ventilated with an LMA, and the right lower lobe was expanded with a long tracheal tube inserted through the LMA via the swivel connector. This combination of a conventional LMA and a commercially available longer paediatric tracheal tube could be another way of providing differential ventilation in infants.
