Upper Airway Surgery

During upper airway surgery ventilation may remain uneventful as long as the airway is open. Unfortunately, typical complications like difficult airways or (suddenly) obstructed airways may occur, leaving the use of an endotracheal small bore catheter or even cricothyrotomy as a final solution for ventilation. In combination with conventional jet ventilation this severely increases the risk on barotrauma.


Ventilating through small bore lumens

The working principle of Evone and Ventrain, facilitating expiration, enables full ventilation through small bore lumens in cases involving critically obstructed upper airways and it strongly reduces the risk on barotrauma. Moreover, it creates additional working space for the surgeon during an upper airway surgery, for example a tumor resection.

Ventrain for different Upper Airway Surgery scenarios

Our ventilation device Ventrain, is able to provide full ventilation of a difficult airway during upper airway surgery. Since Ventrain can be connected to both transtracheal catheters and small bore endotracheal catheters, it can be used in different scenarios:


The following examples are encapsulated in the diagram above.

  • Open airway: The airway is initially open and a small bore endotracheal tube is used to provide more working space; however during the surgery the airway becomes increasingly obstructed. The selected ventilation device (e.g. automatic jet ventilator) no longer provides sufficient ventilation due to the increasing lung pressure. Switching to Ventrain will provide full ventilation and restore blood-gas levels and lung pressure.
  • Difficult airway: The airway is partially occluded, disabling intubation with a large bore tube (ID >6 mm). Instead a long thin endotracheal tube (ID 2-3 mm), or alternatively a transtracheal catheter (ID 2 mm), is used in combination with (automated) jet ventilation, with concomitant risk on high lung pressure, or in combination with manual ventilation by Ventrain, without this increased risk.
  • Obstructed airway: In case of a fully obstructed airway, only Ventrain is able to ventilate through a small bore tube (ID 2-3 mm) or a transtracheal catheter (ID 2 mm) due to its EVA technology, facilitating ventilation.
  • An anticipated difficult airway situation: as a precaution a transtracheal catheter can be placed and in case the airway is occluding Ventrain can be used to ventilate.


Advantages of Ventrain during Upper Airway Surgery

Ventilation with Ventrain during upper airway surgery combines the physical advantages of small bore lumens with the ventilation benefits of Ventrain:

  • full ventilation (oxygenation and active CO2 removal);
  • minute volume up to 7 L/min;
  • non vibrating vocal cords;
  • minimally invasive;
  • better view for surgeon;
  • increased surgical space.
