“Tritube makes my life so much easier, as it provides a great view and an effective ventilation in the compromised airway”
Prof. Dr. Hans Mahieu
Laryngologist, Meander Hospital Amersfoort, The Netherlands
Conventional small lumen ventilation: A lifesaver with drawbacks
Emergency transtracheal jet ventilation (TTJV)
- Used in ‘cannot intubate, cannot oxygenate’ (CICO) situations to save patient’s life 1-3
- Relies on passive egress of gas via nose or mouth, requiring a patent airway
- Bears serious risk of lung damage from barotrauma in obstructed airways 4
- Has a high complication rate 4
– Barotrauma (32%)
– Device failure (42%)
– Any other complication (51%)
Upper airway surgery – challenges
- Jet ventilation requires an open airway to prevent air-trapping
– Induces movement of anatomical structures (e.g. vocal cords)
– Increases risk of aspiration
- Intermittent periods of apnea during surgery
– Prolong duration of surgery
– Increase risk of desaturation and aspiration
- Microlaryngeal tubes with cuff still limit surgical exposure
- Leaving a small-bore tube in situ makes extubation of high-risk patients easier 12,13.
EVA®/FCV® uniquely provides safe small lumen ventilation with full respiratory control
Benefits of Tritube and FCV® by Evone demonstrated in first clinical study
The two-center observational study showed adequate ventilation of patients undergoing ear-nose-throat surgery, with respiratory and hemodynamic parameters within normal clinical range. Good visibility of the laryngeal structures during and after placement of Tritube was demonstrated. With its cuff deflated, Tritube allowed patients to comfortably breathe spontaneously after emergence from anesthesia, and could be left in place until arrival in the post-anesthesia care unit. The authors state that “FCV® in combination with Tritube contributes to the armamentarium for airway management”. Read more.
A patient’s life was saved with Ventrain and Cricath
Deteriorating respiratory distress and decreasing level of consciousness of a transported patient forced an ambulance to stop at the emergency department of the Meander Medical Center Amersfoort. The patient presented with near-complete upper airway obstruction and impending hypoxic arrest. After placement of Cricath, ventilation with Ventrain was conducted for almost 60 minutes, until surgical tracheotomy was performed safely. Oxygenation was restored within 90 seconds, and hemodynamic and ventilatory parameters were stabilized throughout the procedure. Read more.
Ultrathin Tritube compared to standard tubes during ear-nose-throat surgery
Dr. Kristensen reported the first series of cases using Tritube in combination with Ventrain for airway management and ventilation of ear-nose-throat surgical patients. The direct comparison of Tritube and a standard micro-laryngeal tube (MLT-6) during laryngoscopy revealed considerable advantages of Tritube, offering a better view of the laryngeal inlet. Both surgical access and surgical field were judged as excellent by the surgeon. Overall, the authors report that Tritube in conjunction with Ventrain offered new options during upper airway surgery.

EVA®/FCV®– a disruptive ventilation concept
Tritube – an ultrathin cuffed endotracheal tube (OD 4.4 mm)
- Offers unprecedented view of the intubated airway 31
- Provides large surgical exposure and hygienic and clear sight with non-moving vocal cords 31-35
- Allows easy intubation even in difficult airways due to the small OD and malleable stylet 31-35
- Allows awake intubation 31,32
- Is well tolerated when left in situ postoperatively, allowing patients to breathe and talk 31,33,35
