Retrospective Multicentre Observational Study on the Incidence of Hyperoxia in Non-intubated Patients in Intensive Care in Belgium Study OxSIZgen
An observational study of Hyperoxia, run by SIZ Nursing at 1 site in Belgium.
Trial summary
Oxygen is the most widely prescribed therapy in the ICU (intensive care unit) and can save lives in critical patients. While the deleterious effects of hypoxia are apparent and must be actively avoided, hyperoxia also has adverse effects. Read more about this study

About this study
Official title: Prospective Multicentre Observational Study on the Incidence of Hyperoxia in Non-intubated Patients in Intensive Care in Belgium Study OxSIZgen
Oxygen is the most widely prescribed therapy in the ICU (intensive care unit) and can save lives in critical patients. While the deleterious effects of hypoxia are apparent and must be actively avoided, hyperoxia also has adverse effects. These include systemic, coronary and cerebral vasoconstriction; decreased coronary blood flow; pulmonary atelectasis and increased free radicals. Despite these deleterious effects, hyperoxia is common and frequent in the ICU (from 22% to 74%).
A recent meta-analysis published in "The Lancet" with more than 16,000 patients demonstrated an association between liberal oxygen therapy and mortality in critical patients. Other meta-analyses confirm its results with high quality data according to the authors.

A randomized controlled trial published in "The New England Journal of Medicine" comparing liberal versus conservative oxygen therapy showed no difference in mechanical ventilation days and mortality (The ICU-ROX, 2019). However, the difference in PaO2 between the two groups was very small and the PaO2 in the liberal group did not exceed 100 mmHg. In any case, conservative oxygen therapy is safe for critical patients.
The recommendations therefore recommend an oxygen saturation between 94-97% in critical patients and 88-92% in patients with COPD (Chronic Obstructive Pulmonary Disease) .
However, to our knowledge, no study has described the incidence of hyperoxia in non-intubated patients in the intensive care unit.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Oxygen is the most widely prescribed therapy in the ICU (intensive care unit) and can save lives in critical patients. While the deleterious effects of hypoxia are apparent and must be actively avoided, hyperoxia also has adverse effects. These include systemic, coronary and cerebral vasoconstriction; decreased coronary blood flow; pulmonary atelectasis and increased free radicals. Despite these deleterious effects, hyperoxia is common and frequent in the ICU (from 22% to 74%).
A recent meta-analysis published in "The Lancet" with more than 16,000 patients demonstrated an association between liberal oxygen therapy and mortality in critical patients. Other meta-analyses confirm its results with high quality data according to the authors.
A randomized controlled trial published in "The New England Journal of Medicine" comparing liberal versus conservative oxygen therapy showed no difference in mechanical ventilation days and mortality (The ICU-ROX, 2019). However, the difference in PaO2 between the two groups was very small and the PaO2 in the liberal group did not exceed 100 mmHg. In any case, conservative oxygen therapy is safe for critical patients.

Questions about this trial
What is this clinical trial studying?
An observational study of Hyperoxia, run by SIZ Nursing at 1 site in Belgium.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 8 Oct 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Belgium. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
INCIDENCE HYPEROXIA (time frame: one week). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04291911, which also lists 13 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Oct 2020.
