Abstract :
Abstract Objective: In our study, we aimed to investigate the parameters of perfusion management in patients who were diagnosed with coronary artery disease and underwent cardiopulmonary bypass and coronary artery bypass surgery in the last 20 years in our center. Material and Methods: For this study, a total of 485 patients (286 males and 199 females) over 18 years of age who underwent coronary artery bypass surgery with cardiopulmonary bypass support were included in this retrospective study. Patients were grouped according to the number of coronary vessels treated. KABCX1: Single-vessel bypass, KABCX2: Two-vessel bypass, KABCX3: Three-vessel bypass, KABCX4: Four-vessel bypass, KABCX5: Five-vessel bypass. Statistical analyses and comparisons of cross-clamp/min and Total/min values, as well as entry-exit pH, pO2, paCO2, K+, Hct and BE parameters were performed between these groups. Results: When the data of a total of 485 patients were examined, statistical analysis of different parameters in KABCX1, KABCX2, KABCX3, KABCX4 and KABCX5 groups was performed. According to this analysis; Cross-clamp/min and Total/min values were found to be statistically significant (**p0.05). Discussion and Conclusion: We believe that safe perfusion can be achieved by keeping the values of pH, pO2, paCO2, BE, Hct and K+ parameters within the reference ranges, while keeping the cross-clamp/total pump times as short as possible in operations where the use of a heart-lung machine is required, such as coronary artery bypass surgery.
