Clinical Trial Summary

In a prospective observational study during the six-month duration, coronary artery bypass graft surgery (CABG) and valve repair surgery (mitral, mitral, and aortic valve and/or tricuspid valve) patients were investigated for hepatic dysfunction. All patients were divided into two groups as with or without hyperbilirubinemia, and this was defined by the occurrence of a plasma total bilirubin concentration of more than 34 µmol/L (2 mg/dL) in any measurement during the postoperative period. Our goal was to determine the risk factors associated with hepatic dysfunction in patients undergoing open-heart surgery with cardiopulmonary bypass. The collected parameters include; alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP), total bilirubin (TBIL), and gamma-glutamyl transpeptidase (GGT) and albumin preoperatively and on postoperative days 1, 3 and 7. Possible preoperative, intraoperative, and postoperative risk factors were investigated. Logistic regression analysis was done to identify the risk factors for postoperative hyperbilirubinemia.


Description:

There are a series of pathophysiological changes in patients undergoing open-heart surgeries with cardiopulmonary bypass (CPB) that causes liver hypoperfusion, centrilobular sinusoid ischemia, and subsequent reperfusion injuries, hemolysis, or systemic inflammatory response. These events may eventually lead to various forms of hepatic dysfunction in patients during the postoperative period after open-heart surgeries. An increased incidence of liver function test abnormalities were reported, and the rates vary between 10 % and 40%. The occurrence of postoperative hyperbilirubinemia is crucial in increased morbidity and mortality after open-heart surgery with CPB. There are several reports of the possible risk factors that are associated with hepatic dysfunction. In previous studies, the incidence of postoperative hyperbilirubinemia was between the range of 20% up to 51% in open-heart surgeries with CPB. The causes of this higher incidence were related to the presence of various possible risk factors, and these include; valvular heart disease and related low cardiac output states, and low ejection fraction. Other important risk factors for postoperative hepatic dysfunction after open-heart surgery with CPB were longer operative time and a larger volume of blood transfusion. However, CPB itself is not a significant constituent in the postoperative development of hyperbilirubinemia. Splanchnic ischemia before or during operation and in the postoperative period appears to be an essential cause. Other risk factors that were identified as possible risk factors for postoperative hepatic dysfunction. We can list these factors as; poor preoperative heart function, hemodynamic instability, emergency surgery, and preoperative liver dysfunction. Our goal was to determine the possible risk factors associated with hepatic dysfunction in patients undergoing open-heart surgery with CPB.

Study Design


Intervention

Procedure:
Open-Heart Surgery for nine months duration
In a single group of patients including 340 patients undergoing open-heart surgery during a period of nine months, the collected parameters include; alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP), total bilirubin (TBIL), and gamma-glutamyl transpeptidase (GGT) and albumin preoperatively and on postoperative days of 1, 3 and 7. All patients were divided into two groups as with or without hyperbilirubinemia, and this was defined by the occurrence of a plasma total bilirubin concentration of more than 34 µmol/L (2 mg/dL) in any measurement during the postoperative period. For each diagnostic test, a comparison within the group for different time points was statistically evaluated by analysis of variance tests.
Other:
Relation between possible risk factors and hyperbilirubinemia
Possible preoperative, intraoperative, and postoperative risk factors were investigated. The relations between hyperbilirubinemia and possible risk factors are sought by the use of the statistical analysis methods including logistic regression analysis.
Follow-up period
All patients were investigated for a period of ten days postoperatively. During this period, intensive care unit (ICU) stay, in-hospital stay, and all adverse events were recorded.
