Brief Summary:
The purpose of study is to test whether perioperative sodium bicarbonate infusion can prevent acute kidney injury following open heart surgery in infective endocarditis patients.

Arm Intervention/treatment
Experimental: Sodium bicarbonate group
Sodium bicarbonate group
Drug: sodium bicarbonate
0.5 mmol/kg for 1 hr, and then 0.15 mmol/kg/h for 23 hrs The infusion of study drug is started after anesthesia induction and continued until 24 hours after surgery

Placebo Comparator: Saline group
Saline group
Drug: Saline

Primary Outcome Measures :
  1. 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
