Clinical Trial[Specificity of CK-MB enzyme in the diagnosis of acute myocardial infarction in the postoperative period following non-cardiac surgery].
1) To determine plasma concentrations of creatinphosphokinase-MB (CK-MB) enzyme during non-cardiac surgery for detecting postoperative myocardial infarction or ischemia. 2) To assess the specificity of CK-MB levels for the diagnosis of acute myocardial infarction (AMI) in patients undergoing non-cardiac surgery. ⋯ 1) The CK-MB/total CK ratio is highly specific for detection AMI after surgery. 2) Type of surgery affects total CK levels. 3) Detection of high levels of MB fraction should lead to a suspicion of myocardial damage. 4) Total CK level is not a good marker of myocardial necrosis in the postoperative period.

Randomized Controlled Trial Clinical Trial[Optimization of ventricular function during anesthesia induction by administering crystalloids and colloids to heart surgery patients].
To describe the changes in cardiac function after administration of three different solutions infused after anesthetic induction. ⋯ Administration of restricted doses of crystalloids after anesthetic induction favors the retention of water and sodium. Higher doses of crystalloids weaken this effect. However, neither of these two regimens leads to a more effective cardiac work load. A combination of crystalloids and colloids administered immediately after anesthetic induction temporarily improves cardiac performance during surgery.
