Early Diuretics for De-resuscitation in Septic Patients With Left Ventricular Dysfunction

Area of Science:

• Critical Care Medicine
• Cardiology
• Pharmacology

Background:

• De-resuscitation strategies for septic patients with heart failure (HF) are not well understood.
• Fluid balance management is crucial in critically ill patients.

Purpose of the Study:

• To investigate the association between early diuretic initiation (within 48 hours) and fluid balance in intensive care unit (ICU) patients with sepsis and HF.
• To evaluate the impact of early diuresis on patient outcomes.

Main Methods:

• A single-center, retrospective cohort study of 101 adult patients with HF admitted to the ICU with sepsis or septic shock.
• Comparison of positive fluid balance, hospital mortality, mechanical ventilation duration, and length of stay between early (<48 hours) and late (>48 hours) diuretic initiation groups.
• Statistical analysis included independent t-tests, Mann-Whitney U tests, and Pearson Chi-squared tests.

Main Results:

• Early diuretic initiation was associated with a significantly reduced positive fluid balance at 72 hours (-139 mL vs 4370 mL, P < .001).
• No significant differences were observed in hospital mortality, ventilator-free days, or overall ICU/hospital length of stay between groups.
• In a subgroup analysis excluding patients on renal replacement therapy, early diuresis was linked to lower rates and shorter duration of mechanical ventilation (P = .01 and P = .018, respectively).

Conclusions:

• Initiating diuretics within 48 hours of ICU admission in septic patients with HF effectively reduces positive fluid balance.
• Early diuresis may be beneficial in reducing mechanical ventilation requirements in select HF patients without renal replacement therapy.
• Further investigation into early diuretic use in this specific patient population is warranted.
