Trial summary

About this study
Rationale:
During perioperative period, prolonged starvation, surgical stress, acute complications (e.g. infection) and medication changes all promote ketone generation, therefore increasing the risk of ketoacidosis. At present, there is no literature concerning the ketone production in patients undergoing cardiac surgery, regardless of the diabetes status.
Objectives:
The objectives of this study are to explore the change in blood ketone level during the perioperative period in patients with and without diabetes, to observe the incidence of perioperative ketoacidosis, and to investigate therapy and outcome of patients with perioperative ketoacidosis.
Read the detailed description
Study procedures On the first day of admission, all the patients scheduled for cardiac surgery with an on-pump procedure will be asked for a consent for anonymous using of their information. Patients giving permission will be screened for participation in this study, and those fulfil the inclusion/exclusion criteria will be included for further research.
Blood ketone will be measured with StatStrip Glucose/Ketone Meters (Nova biomedical, United Kingdom) using sample leftover from blood gas analysis. No extra blood draw is needed. The levels of ketones will be measured at four time points:
- Beginning of surgery;
- The moment the cardio-pulmonary bypass machine takes over the circulation.
- After the decoupling of the Cardio-pulmonary bypass machine
- At the end of surgery.
Diagnosis of ketoacidosis is based on criteria mentioned. Epidemiology characteristics and perioperative variables will be extracted from electronic medical records.

What is being measured
The primary outcome is the main question the study is designed to answer.
Blood ketone difference
The primary outcome in this study is the difference in blood ketone level before and after cardiac surgery.
Measured: During surgery
Secondary outcomes (2)
Incidence of ketoacidosis
The diagnosis criteria for Ketoacidosis are: 1) Beta-hydroxybutyrate (BHB) ≥3 mmol/L or significant ketonuria (≥ ++); 2) blood glucose over 11 mmol/L; and 3) bicarbonate below 15 mmol or arterial potential of hydrogen(pH) less than 7.3.
Measured: Post surgery up to three days
Difference in ketone development between patient with and without diabetes mellitus.
Glucose management is compared between two groups to see if there is a potential difference.
Measured: During Surgery

Questions about this trial
What is this clinical trial studying?
An observational study of Ketosis and Keto Acidosis, run by Academisch Medisch Centrum - Universiteit van Amsterdam (AMC-UvA) at 1 site in Netherlands.
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 2 inclusion and 5 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 20 Jul 2023. 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 Netherlands. 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?
Blood ketone difference (time frame: During surgery). 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 NCT05225467, which also lists 8 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 20 Jul 2023.
