Evaluation of Lung Atelectasis During Apneic Oxygenation Using THRIVE in Adults During Laryngeal Surgery. (A-THRIVE)

Brief Summary:
Oxygenation with high-flow nasal cannula with 100% oxygen have now been evaluated in a number of studies and the data are convincing. The THRIVE technique is able to oxygenate patients safely and vital parameters has been shown to be stable. But it is of great importance to evaluate this new concept regarding other potential negative physiological aspects such as lung atelectasis and inflammatory stress response before implementing it into clinical practice.

Arm Intervention/treatment
Active Comparator: Intubation
The patients will be intubated and ventilated
Device: Endotracheal intubation
Ventilation during the procedure is governed by an endotracheal tube in the trachea and mechanical ventilation

Experimental: THRIVE
The patients will be oxygenated during apnea using THRIVE
Device: THRIVE
Oxygenation during apnea using transversal humidified oxygen

Primary Outcome Measures :
  1. Electrical impedans tomography [ Time Frame: baseline, intraoperative, 2 hours after start of intervention ]
    Changes in lung volumes

Secondary Outcome Measures :
  1. Difference in Endtidal and arterial carbon dioxide partial pressure in the end of the procedure [ Time Frame: max 30 minutes after start of intervention ]
    Difference in Endtidal and arterial carbon dioxide partial pressure in the end of the procedure

  2. Increase in arterial carbon dioxide during the apnea [ Time Frame: max 30 minutes after start of intervention ]
    Measurement of arterial blood gases and here arterial carbon dioxide
