Upper Airway Surgery
During upper airway surgery ventilation may be challenging, as it needs to provide a clear and hygienic surgical opening and to handle any potential for obstructed airways. Working in combination, Tritube, Evone or Ventrain fulfill all these needs.
Full ventilation and less risk of barotrauma
A small bore tube may be preferred in order to create surgical exposure. The working principle of Evone and Ventrain, facilitating expiration, enables full ventilation through small bore lumens providing adequate ventilation even in cases involving critically obstructed upper airways. In comparison to traditional jet ventilation, it strongly reduces the risk of barotrauma
Clear and hygienic surgical environment and secured airway
Tritube has a cuff to seal the airway, which reduces the risk of aspiration. As well as creating a clear and hygienic surgical field, the cuff prevents vibration of the vocal cords via injected and exhaled gases.
Ventilation with an open unsealed airway
A cuff may create stimuli in the trachea while waking up from anesthesia, resulting in coughing. This may be not be ideal after upper airway surgery. By deflating the cuff of Tritube, the patient can be oxygenated using jet ventilation by Evone or by FCV ventilation by Evone or Ventrain, when gases are injected by a set (low) flow.
Advantages of Evone, Ventrain and Tritube during Upper Airway Surgery
- Full ventilation (oxygenation and active CO2 removal);
- Non-vibrating vocal cords;
- Minimally invasive;
- Clear and hygienic working surgical environment;
- Increased surgical space.
Prof. Barnes, together with Van Asseldonk and Enk, provide clear theoretical evidence for lower energy dissipation in the lungs by FCV® as compared to VCV or PCV. They present a simple analysis and numerical calculations indicating that energy dissipation may be...
