Masking: Triple (Participant, Care Provider, Investigator)
Primary Purpose: Prevention

Further study details as provided by Yonsei University:

Primary Outcome Measures:
  • Comparison of the the peak creatinine level during the postoperative 48h by more than 0.3 mg/dL between two groups. [ Time Frame: postoperative 48 hours ]

    We would investigate if the peak creatinine level during the postoperative 48h would differ by more than 0.3 mg/dL between two groups. The primary outcome was decided based on the AKIN criteria which defines acute kidney injury if serum creatinine increases more than 0.3 mg/dL during the postoperative 48 h.

    ; increase in serum creatinine of 0.3 mg/dL or >50 percent developing over <48 hours

Estimated Enrollment: 70
Study Start Date: August 2013
Estimated Study Completion Date: August 2016
Estimated Primary Completion Date: August 2016 (Final data collection date for primary outcome measure)
