Background: Hydroxyethyl starch (HES) solutions increase the risk of acute kidney injury (AKI) in critically ill patients admitted to intensive care unit (ICU) for medical indications. We conducted a cohort study to evaluate the renal safety of modern 6% HES solutions in high-risk patients having cardiac surgery.

Method: In this multicentre prospective cohort study, we recruited 261 consecutive patients at high-risk for developing cardiac surgery-associated AKI, based on a Cleveland score ≥ 4 points, from July to December 2017th in 14 hospitals in Spain and the United Kingdom. Multivariable logistic regression modeling and propensity-score matched-pairs analysis were used to determine the adjusted association between administration of HES and AKI.

Results: Of the cohort, 95 patients (36.4%) received 6% HES 130/0.4 either intraoperatively or postoperatively. Postoperative AKI occurred in 145 patients (55.5%). The unadjusted odds of AKI was significantly higher in the HES group, when compared to those not receiving HES (OR 2.22, 95% CI 1.30-3.80, p = 0.003).

In multivariable logistic regression models, modern HES was not associated with significantly increased risk of AKI (adjusted OR 0.84, 95% CI 0.41-1.71, p = 0.63). In propensity score match-pairs analysis of 188 patients, the HES group experienced similar adjusted odds of AKI (OR 1.05, CI 95% 0.87-1.27, p = 0.57) and RRT (OR 1.06, CI 95% 0.92-1.22, p = 0.36).

Conclusions: The use of modern hydroxyethyl starch 6% HES 130/0.4 was not associated with an increased risk of AKI nor dialysis in this cohort of patients at elevated risk for developing AKI after cardiac surgery.
