Condition
Injury of Other and Multiple Parts of Small Intestine

Study Type: Observational
Study Design: Time Perspective: Prospective
Official Title: Official Title is Required by the WHO and ICMJE

Further study details as provided by First Affiliated Hospital, Sun Yat-Sen University:

Primary Outcome Measures:
  • score of gut dysfunction [ Time Frame: eight months ] [ Designated as safety issue: No ]
    At different time points, gut dysfunction is graded according to previous criterion.


Secondary Outcome Measures:
  • The duration of cardiopulmonary bypass [ Time Frame: Eight months ] [ Designated as safety issue: No ]
    Record the duration of cardiopulmonary bypass

  • The duration for aortic artery clamping [ Time Frame: eight months ] [ Designated as safety issue: No ]

Biospecimen Retention:   Samples With DNA

Blood samples are retained for the detections of some biomarkers and gene polymorphism.

Estimated Primary Completion Date: October 2012 (Final data collection date for primary outcome measure)
Groups/Cohorts
patients with cardiac surgery

Detailed Description:

Intestinal injury is one of main reasons for mobidity and mortality after heart valve replacement, but its incidence and potential risk factors remain unclear. A multicenter study in China is undertaken to investigate the incidence and predictive factors related to intestinal injury in patients undergoing heart valve replacement.
