Assessment of Outcomes in Patients with Heart Failure and End-Stage Kidney Disease after Fluid Resuscitation for Sepsis and Septic Shock.

BACKGROUND

Sepsis fluid resuscitation is controversial, especially for patients with volume overload risk. The Surviving Sepsis Campaign recommends a 30-mL/kg crystalloid fluid bolus for patients with sepsis-induced hypoperfusion. Criticism of this approach includes excessive fluid resuscitation in certain patients.

OBJECTIVE

The aim of this study was to assess the efficacy and safety of guideline-concordant fluid resuscitation in patients with sepsis and heart failure (HF) or end-stage kidney disease (ESKD).

METHODS

A retrospective cohort study was conducted in patients with sepsis who qualified for guideline-directed fluid resuscitation and concomitant HF or ESKD. Those receiving crystalloid fluid boluses of at least 30 mL/kg within 3 h of sepsis diagnosis were placed in the concordant group and all others in the nonconcordant group. The primary outcome was in-hospital mortality. Secondary outcomes included intensive care unit (ICU) and hospital length of stay (LOS); vasoactive medications and net volume over 24 h; new mechanical ventilation, new or increased volume removal, and acute kidney injury within 48 h; and shock-free survival at 7 days.

RESULTS

One hundred twenty-five patients were included in each group. In-hospital mortality was 34.4% in the concordant group and 44.8% in the nonconcordant group (p = 0.1205). The concordant group had a shorter ICU LOS (7.6 vs. 10.5 days; p = 0.0214) and hospital LOS (12.9 vs. 18.3 days; p = 0.0163), but increased new mechanical ventilation (37.6 vs. 20.8%; p = 0.0052). No differences in other outcomes were observed.

CONCLUSIONS

Receipt of a 30-mL/kg fluid bolus did not affect outcomes in a cohort of patients with mixed types of HF and sepsis-induced hypoperfusion.
