About this study
Official title: Factors Affecting Extubation Time in Coronary Artery Bypass Surgery
Many preoperative, intraoperative, and postoperative factors affect the postoperative extubation times of patients who are intubated and taken to the intensive care unit after cardiac surgery. Numerous studies have been conducted to evaluate these variables affecting extubation time. The purpose of this study is to determine whether any preoperative, intraoperative or postoperative variable have a significant effect on extubation time after coronary artery bypass graft surgery. The research is conducted on patients who underwent coronary artery bypass surgery within the last year at Gazi Yaşargil Training and Research Hospital in Diyarbakır, Turkey. The study design is retrospective. Therefore, the study poses no additional risk to the patients.

The study design is retrospective. Therefore, the study poses no additional risk to the patients.
Demographic data, preoperative factors (Ejection fraction, laboratory values, reasons for operation, existing comorbid diseases), intraoperative parameters (heart rate, blood pressure values), duration of surgery, anesthesia and pump time, and and postoperative variables (Length of stay in the ICU and service, amount of bleeding, amount of blood products administered) will be recorded.
The study aims to identify factors influencing extubation in this patient group and strive for early extubation.

Questions about this trial
What is this clinical trial studying?
An observational study of Coronary Artery Bypass, run by Saglik Bilimleri Universitesi at 1 site in Turkey (Türkiye).
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 2 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 14 May 2026. 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 Turkey (Türkiye). 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?
Time to extubation (time frame: Up to 24 hours postoperatively.). 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 14 May 2026.
