The aim of this experimental study was to evaluate the efficacy of a Y-shaped catheter for the prevention of accumulation of carbon dioxide (CO2) in tracheal surgery.<\/jats:p><\/jats:sec><jats:sec><jats:title>METHODS<\/jats:title><jats:p>Surgery for tracheal resection and reconstruction was performed in 10 beagles under general anaesthesia. Before transecting the trachea, the dogs were hyperventilated for 10\u2009min with pure oxygen. After the airway was opened, ventilation was maintained with a small catheter for apnoeic oxygenation for 30\u2009min until the end of the tracheal reconstruction. Y-shaped catheters were used in 5 dogs and straight catheters were used in 5 dogs for oxygen insufflation.

The total CO2 partial pressure elevation value was 59.5\u2009mmHg in the Y-shaped catheter group and 89.0\u2009mmHg in the straight catheter group (P\u2009&lt;\u20090.006).
