Extubation Time in Coronary Artery Bypass Surgery

May 12, 2026 updated by: Selen Topalel, Saglik Bilimleri Universitesi

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.

Detailed Description

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.

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.
