Extracorporeal Blood Purification and Acute Kidney Injury in Cardiac Surgery

JAMAPublished

  • Randomised controlled trial
  • double-blind
  • 2 tertiary hospitals in Spain

Authors' conclusion

The use of a nonselective EBP device connected to the CPB circuit in a nonemergent population of patients undergoing cardiac surgery was associated with a significant reduction of CSA-AKI in the first 7 days after surgery.

Study context

Population
Adults undergoing nonemergent cardiac surgery at high risk for cardiac surgery-associated acute kidney injury (CSA-AKI)
Participants
343 adults
Comparison
Extracorporeal blood purification vs standard care during cardiopulmonary bypass (CPB)
  • Extracorporeal blood purification (EBP)n = 169
  • Standard caren = 174reference
Primary endpoint
Rate of cardiac surgery-associated AKI
Follow-up
7 days after randomization

Primary result

As reported in the abstract

Adjusted difference

10.4%

95% CI 2.3%–18.5%

P = 0.01

By group

EBP vs Standard care
adjusted difference 10.4% (95% CI 2.3%–18.5%); P = 0.01

Secondary outcomes

Predefined clinical secondary and post hoc exploratory end points

No significant differences in most end points
P > 0.05

CSA-AKI by subgroup (sensitivity analysis)

EBP more effective in CKD, DM, hypertension, LVEF <40% and BMI <30

Safety

Adverse events

No differences between groups in adverse events tracking
