About this study
Official title: Effect of Retrograde Autologous Blood Priming of Cardiopulmonary Bypass on Hemodynamic Parameters and Pulmonary Mechanics in Pediatric Cardiac Surgery
The present study hypothesized that beyond its hemodynamic affects,retrograde autologus blood priming of cardiopulmonary bypass (RAP) has a positive impact on hemodynamics and pulmonary mechanics subjected to cardiac surgery.
Read the detailed description
This prospective randomized study analyzed the clinical records of 124 children subjected to cardiac surgery for congenital heart diseases with left to right shunt. They comprised 64 patients with RAP and 60 patients conventional cardiopulmonary bypass priming. The preoperative, intraoperative and postoperative data of the studied patients were reported.

Questions about this trial
What is this clinical trial studying?
A study testing Pediatric cardiac surgery in people with Congenital Heart Disease, run by Ain Shams University.
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 1 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 4 Mar 2020. Status can change between updates, so confirm with the study contact before making plans.
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?
Comparison of postoperative peak air way pressure between the studied groups (time frame: 1 hour after surgery). The study lists 5 primary outcomes in all. 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 4 Mar 2020; AzTrials last refreshed its copy on 8 Nov 2026.
