Prolonged Cardiopulmonary Bypass Time as a Predictive Factor for AGI After Heart Valve Replacement
Study Details
Study Description
Brief Summary
In this retrospective study, the investigators will analyze the correlation between cardiopulmonary bypass (CPB) time and acute gastrointestinal injury (AGI), and the outcomes of AGI in patients undergoing heart valve replacement.

Detailed Description
Patients with heart valve diseases often have chronic cardiac insufficiency. Patients undergoing heart valve replacement with CPB are always complicated with gastrointestinal tract ischemia-reperfusion injury, which usually leads to AGI. AGI after cardiovascular surgery, especially in that use CPB, is associated with significant morbidity and an increase in peri-operative mortality. Prolonged CPB time could be predictive of AGI following heart valve replacement. This study is to analyze the correlation between CPB time and AGI, and the outcomes of AGI in patients undergoing heart valve replacement. The investigators hope that the benefits will include fewer patients becoming seriously postoperative AGI and mortality after cardiac surgery.

Outcome Measures
Primary Outcome Measures
- Cardiopulmonary bypass (CPB) time [1 month]
Was defined it as the sum of times of CPB during surgery (minutes).
- The AGI score [1 month]
The AGI score of the patient within the seventh postoperative day was performed according to the European Society of critical care (2012) guidelines for AGI.
Secondary Outcome Measures
- Number of bowel sounds [1 month]
The return time of bowel sounds was evaluated morning and evening.
- First defecation time [1 month]
The time to the first defecation was asked morning and evening after surgery
- Proportion of cocci and bacilli in feces [1 month]
The first feces were collected in sterile containers for the bacterial smear
- Alanine aminotransferase (ALT) [1 month]
We defined it as the maximum value of ALT within 7 days after surgery.
- Aspartate aminotransferase (AST) [1 month]
We defined it as the maximum value of AST within 7 days after surgery
- Left ventricular ejection fraction (LVEF) [1 month]
We measured the LVEF on the 1st and 3rd days after operation by echocardiographic examinations
