Endotracheal Tube Size Effect on the Carbon Dioxide Washout During Jet Ventilation

Sweden26 participantsStarted 2022-06-13

Plain-language summary

High Frequency Jet Ventilation (HFJV) can be used in liver tumour ablation to minimise breathing related movements. The jet cannula is placed freely inside an endotracheal tube (ETT) and the outflow of air is passive, moving out in the interspace between the jet cannula and the inner walls of the ETT. This study aims to investigate whether the tube size can influence the washout of carbon dioxide using two different sizes of ETT's.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Inclusion Criteria: * Male patients scheduled for stereotactic liver tumour ablation. * Need for an arterial line for safe monitoring of hemodynamic and respiratory variables during the procedure/anaesthesia. * Ability to understand the information about the study and be able to leave a written, informed consent. Exclusion Criteria: * Patients with known CO2 retention. * Patients shorter than 160 cm (as an endotracheal tube size 9 would then be too big).

What they're measuring

Carbon dioxide level from an arterial line (PaCO2) after 15 minutes of HFJV.

Timeframe: 15 minutes after the start of HFJV
