Plasma expansion and renal perfusion in critical COVID‐19 with acute kidney injury (AKI): A prospective case control study

Acta Anaesthesiol ScandPublished Prospective case control study

Authors' conclusion

Plasma expansion with a standardized fluid bolus did not increase renal perfusion in critically ill patients with COVID-19, with or without AKI.

Study context

Population
ICU-treated critical COVID-19 patients without underlying kidney disease
Participants
9 vs 8
Exposure
AKI vs Without AKI
  • AKIn = 9
  • Without AKIn = 8reference
Outcome
Renal perfusion (MRI phase contrast and arterial spin labeling) before and directly after plasma expansion
Follow-up
Directly after plasma expansion

Main finding

As reported in the abstract

Total renal and cortical perfusion
  • Total renal perfusion and cortical perfusion not significantly changed by plasma expansion in either group

Observational data: associations, not effects.

Further findings

MAP increase after plasma expansion

Medullary perfusion, without AKI

Medullary perfusion before plasma expansion, without AKI
55 (mL/min/100 g; 95% CI 39-79)
Medullary perfusion after plasma expansion, without AKI
34 (mL/min/100 g; 95% CI 24-48)
Reduction, P
P = 0.0027

MAP increase after plasma expansion

Hemodynamic response to plasma expansion similar in both groups
