Transcutaneous Partial Oxygen and Carbon Dioxide Pressures Compared With Blood Gas Values (OxiVenT)
February 4, 2019 updated by: Vera Bernet, MD
Agreement of Transcutaneous Partial Oxygen and Carbon Dioxide Pressure With Arterial and Capillary Blood Gas Values. A Single Centre Prospective Non-randomized Trial in Critically Ill Neonates.
Partial blood oxygen and carbon dioxide pressures obtained in critical ill neonates by transcutaneous sensors will be compared to respective values obtained by medically indicated arterial and capillary blood gas analyses.
The influence of blood withdrawal method, sensor operational temperature and application time, presence of cyanotic heart malformations and/or intra or extra cardiac right to left shunt, vasoactive drugs, elevated non-conjugated bilirubin, and skin and soft tissue oedema, skin colour and perfusion conditions will be elucidated as well as sensor's safety.
Study duration will be 48 hours with sensors applied and additional 4 hours of further surveillance for thermal injury.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
EXPERIMENTAL: All included patients
All included patients will undergo the intervention of transcutaneous sensor placement
|
The sensor will be attached to four anatomical positions (thoracic left and right; abdominal left and right), starting with the left thoracic position followed by 4-hourly clockwise position rotation.
In case of severe oedema, the ear lobes will be used as anatomical measurement sites and changes to the contralateral ear lobe are made every 4 hours.
