Jet ventilation for anterior paediatric scoliosis surgery.
Single-lung anaesthesia for thoracotomy is usually achieved with endobronchial intubation, a double-lumen tube or an endobronchial blocker. High-frequency jet ventilation (HFJV) is seldom described for thoracotomy in children, although it is used for both laryngology procedures in the operating room and as a ventilation mode in intensive care. HFJV was used in three children, aged 10-12 years, who presented for scoliosis correction involving thoracotomy. The jet ventilation catheter was passed through a tracheal tube to reduce the risk of outflow obstruction and allow a smooth conversion to intermittent positive-pressure ventilation when required. Mean airway pressures measured at the tip of the HFJV catheter were at or below 4 cmH2O. Surgical opening of the nondependent lung pleura resulted in sufficient collapse of the pulmonary parenchyma with the patient in the lateral decubitus position for the surgical procedure. Arterial blood gas analyses performed during thoracotomy were within normal limits, with no CO2 retention. HFJV is an alternative ventilation strategy for thoracotomy in children because of its unique ability to deliver small tidal volumes at low mean airway pressures via a narrow catheter.
