ABSTRACT
Objective:
Today, different preventive methods have been developed for myocardial dysfunction in patients undergoing coronary artery bypass graft (CABG) surgery, especially in the postoperative period. One of the most commonly used methods among these is the application of hypothermia during the aortic cross clamp.
Materials and Methods:
A total of 30 patients who underwent coronary bypass surgery under elective conditions under mild hypothermic and normothermic cardiopulmonary bypass in the Cardiovascular Surgery clinic of Private Çorlu Reyap Hospital were included in the study with their consent. Thirty patients who had CABG operation were evaluated retrospectively in 2 groups as normothermic (n=15) and hypothermic (n=15). Mild hypothermia was applied to half of the patients during aortic cross-clamping. The other half of the patients underwent normothermia during aortic cross clamping. The effect of cardiac normothermia on postoperative serum parameters (leukocyte, thrombocyte and hemoglobin counts were taken and activated coagulation time was measured, aspartate aminotransferase, alanine aminotransferase, creatinine, urea, C-reactive protein values from biochemistry samples were examined), blood product replacement amount (fresh frozen plasma and erythrocyte suspension) and the amount of drainage were examined.
Results:
In patients who underwent isolated primary coronary bypass surgery in our clinic, the inflammatory response was lower in the cardiac mild hypothermia group than in the cardiac normothermia group, although it was not statistically significant. However, the results were not statistically significant in serum parameters between groups. At the same time, statistically significantly less drainage was detected in the mild hypothermia group than in the normothermia group. The result was not significant in terms of blood product replacement amount.
Conclusion:
As a result, in elective conditions, there is no big difference between normothermic cardiopulmonary bypass and mild hypothermic cardiopulmonary bypass in terms of postoperative serum parameters and blood product replacement amount, but mild hypothermia is safer in terms of drainage amount.
