ABSTRACT
OBJECTIVES:
To determine whether balanced solutions can reduce the incidence of acute kidney injury after off-pump coronary artery bypass surgery compared with saline.DESIGN:
Randomized controlled trial.SETTING:
Single tertiary care center.PARTICIPANTS:
Patients who underwent off-pump coronary artery bypass surgery between June 2014 and July 2020.INTERVENTIONS:
Balanced solution-based chloride-restrictive intravenous fluid strategy. MEASUREMENTS AND MAINRESULTS:
The primary outcome was acute kidney injury within 7 postoperative days, as defined by the 2012 Kidney Disease Improving Global Outcomes Clinical Practice Guideline. The incidence of acute kidney injury was 4.4% (8/180) in the balanced group and 7.3% (13/178) in the saline group. The difference was not statistically significant (risk difference, -2.86%; 95% confidence interval [CI], -7.72% to 2.01%; risk ratio, 0.61, 95% CI, 0.26 to 1.43; p = 0.35). Compared with the balanced group, the saline group had higher levels of intraoperative serum chloride and lower base excess, which resulted in a lower pH.CONCLUSIONS:
In patients undergoing off-pump bypass surgery with a normal estimated glomerular filtration rate, the intraoperative balanced solution-based chloride-restrictive intravenous fluid administration strategy did not decrease the rate of postoperative acute kidney injury compared with the saline-based chloride-liberal intravenous fluid administration strategy.
