The Papworth BiVent Tube is a single-use device constructed of moulded non-latex rubber with two D-shaped lumens arranged in a side-by-side configuration, separated by a central partition. The tube has a preformed single posterior concavity and a single inflatable, high volume, low pressure tracheal cuff. At the distal end two pliable, crescent-shaped flanges arising from the central partition to form a forked tip. The tube has been designed to be positioned with this forked tip seated on the carina.
Provision of one lung ventilation can be technically challenging, particularly for anaesthetists who are only occasionally required to isolate one lung from the other.
A new double lumen endotracheal tube, the Papworth BiVent Tube, has been designed to enable rapid and reliable lung isolation using any bronchus blocker without the need for fibreoptic endoscopic guidance.
In this study, an airway-training manikin was used to assess ease of tracheal intubation and lung isolation using the Papworth BiVent tube.
Ease of intubation was compared to a single lumen endotracheal tube and a conventional double lumen endobronchial tube.
Ease of lung isolation when using a bronchus blocker was compared to a single lumen tube in combination with a bronchial blocker.
Tracheal intubation with the Papworth BiVent tube was found to be easier than with a conventional double lumen endobronchial tube.
Lung isolation with the Papworth BiVent tube used in combination with a bronchus blocker was achieved more reliably and rapidly than with a single lumen tube and bronchus blocker.
