About this study
Official title: Study of the Relationship Between Rewarming Rate During Cardiopulmonary Bypass and Clinical Prognosis in Infants Undergoing Cardiac Surgery
The purpose of this study is to investigate the relationship between rewarming rate during cardiopulmonary bypass and clinical prognosis in infants undergoing cardiac surgery.
Read the detailed description
There have been many studies indicating that rewarming management plays an important role in cardiac surgery. The purpose of this study is to investigate the relationship between rewarming rate during cardiopulmonary bypass and clinical prognosis in patients undergoing cardiac surgery. Infants undergoing cardiac surgery with cardiopulmonary bypass are randomly assigned to either a slow rewarming strategy (0.24 degrees C/min) or a fast rewarming strategy (0.5 degrees C/min).
- Conditions
- Cardiac Surgery, Cardiopulmonary Bypass, Rewarming Rate
- Being tested
- Slow rewarming strategy, Fast rewarming strategy

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Slow rewarming strategy and Fast rewarming strategy in people with Cardiac Surgery and Cardiopulmonary Bypass, run by Xijing Hospital at 1 site in China.
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 1 inclusion and 4 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: status not confirmed, as of the sponsor's last update on 20 Jul 2011. 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 China. 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.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Chunhu Gu, MD (guchunhu@fmmu.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
all cause mortality (time frame: one year). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 2011; AzTrials last refreshed its copy on 8 Nov 2026.
