Single lung ventilation in children using a new paediatric bronchial blocker

As video-assisted thoracoscopic surgery has become more common in paediatric patients, the use of single lung ventilation in children has also increased. Single lung ventilation in young children is performed by either advancing a tracheal tube into the mainstem bronchus opposite the side of surgery or by positioning a bronchial blocker into the mainstem bronchus on the operative side. Techniques for placing a variety of bronchial blockers outside the tracheal tube have been described. We describe a technique for placement of a new bronchial blocker through an indwelling tracheal tube using a multiport adaptor and a fibreoptic bronchoscope.
