Abstract:
Background: In this present study, we studied the correlation between aortic cross clamp time and Troponin I levels for elective coronary artery bypass graft operations in 91 patients.
Methods: 51 of the patients included in the study were male and 40 of them were female. Troponin I measurements were recorded 3 times for each patient. Blood samples were taken before cross clamping, after cross-clamping (during the operation), and on postoperative 1st day for Troponin I levels. While the comparison of troponin I blood samples taken in 3 periods, the effect of prolonged cross clamp times on troponin I levels was investigated.
Results: Mean age was 54.7 ± 6.7 years. Euro score value was 3.3 ± 1.7. Mean values were 195.7 ± 61.6 mins for operation time, 55.1 ± 23.6 mins for cross clamp time, 124.9 ± 18.9 mins for cardiopulmonary bypass time and 551.9 ± 44.8 mins for intubation time. Internal mammarian artery and saphenous vein grafts were used for coronary anastomosis in all patients. Overall intensive care unit stays were 3.6 ± 1.7 days and hospitalizations were 8.6 ± 5.1 days. Troponin I measurements were significantly higher with longer cross clamping time.
Conclusion: Among patients undergoing elective coronary artery bypass graft operations, there is a direct and linear correlation between aortic cross clamp time and postoperative Troponin I levels. We strongly advocate this 50 mins’ threshold as a safety limit for aortic cross clamp time in elective coronary artery bypass surgery.
