[Effect of ulinastatin for perioperative cardiac protection in elderly patients undergoing major gastrointestinal surgery].
OBJECTIVE
To study protective effect of ulinastatin on perioperative cardiac function in elderly patients undergoing major gastrointestinal surgery.


METHODS
Sixty elderly patients (32 male and 28 female patients) aged 60-82 years scheduled for major gastrointestinal surgery were randomized into ulinastatin group and control group. The patients in ulinastatin group received 2×10(5) U ulinastatin rapidly administered via a intravenous pump immediately before operation with subsequent continuous infusion at the rate of 1×10(5) U until the completion of surgery, and those in the control group received the same amount of saline instead. In both groups, the mean arterial pressure (MAP), heart rate (HR), left ventricular ejection fraction (LVEF), and cardiac output (CO) were monitored immediately before surgery (T0) and at 1 h (T1), 2 h (T2) and 3 h (T3) after the start of surgery. The total dopamine dose used was recorded at the end of surgery, and blood samples were collected at T0 and at 6 h (T4) and 12 h (T5) after the operation for determination of serum levels of cTn, CK-MB and BNP.


RESULTS
In both groups, MAP, LVEF and CO were significantly decreased at T2 and T3 (P<0.05) and serum levels of cTn, CK-MB and BNP significantly increased at T4 and T5 compared to those at T0 (P<0.05). Compared with the control group, the patients in ulinastatin group showed significantly higher MAP, LVEF and CO at T2 and T3 and lower serum levels of cTn, CK-MB and BNP at T4 and T5.


CONCLUSIONS
Ulinastatin offers effective perioerative cardiac protection in elderly patients undergoing major gastrointestinal surgery.
