To explore the effect of intraoperative sodium creatine phosphate on myocardial protection in patients undergoing valve surgery
Objective: To explore the effect of intraoperative sodium creatine phosphate on myocardial protection in patients undergoing valve surgery Methods: 250 patients undergoing valve surgery were randomly divided into experimental group and control group. 5g creatine phosphate was dissolved in 50ml saline solution. After induction of anesthesia, the patients were first given a load dose of 1g, 20min (30ml / h) , And then pumped at a rate of 1 g / h (10 ml / h). The control group was treated with saline in the same manner. The cTnI level was measured at the corresponding time points. Hemodynamic indexes and postoperative complications were recorded.
