A Randomized Controlled Trial of a Conservative Fluid Balance Strategy for Patients With Sepsis and Cardiopulmonary Dysfunction (BALANCE Study)

Sepsis is a common inflammatory response to infection characterized by hypovolemia and vasodilation for which early administration of intravenous fluids has been suggested to improve outcomes. The ideal fluid balance following initial resuscitation is unclear. Septic patients treated in the intensive care unit commonly receive significant volumes of intravenous fluids with resultant positive fluid balance for up to a week after their initial resuscitation. Observational studies have associated fluid receipt and positive fluid balance in patients with severe sepsis and septic shock with increased mortality but are inherently limited by indication bias. In order to determine the optimal approach to fluid management following resuscitation in patients with severe sepsis and septic shock, a randomized controlled trial is needed. The primary hypothesis of this study is that, compared to usual care, a conservative approach to fluid management after resuscitation in patients with sepsis and cardiopulmonary dysfunction will increase intensive care unit free days.

Treatment and study plan

Conservative Fluid Management Strategy

Other

For patients in the conservative fluid management arm, beginning 12 hours after admission to study ICU and ending at the first of ICU discharge, death, return to home inspired oxygen, or study day 14, fluid management will be controlled by a study protocol. Patients in shock will receive fluid boluses only as specified by the protocol for oliguria and rapidly increasing vasopressor requirement. Patients not in shock will receive fluid boluses only as specified by the protocol for oliguria. Output will exceed input each day using a diuretic drip if required. Study protocol will be held only for pre-specified Safety Endpoints of persistent oliguria, decompensating shock, diuretic side effect, and intervening acute event.

Primary outcomes

  1. ICU-free Days to 14 Days After Enrollment

    Time frame: 14 days

    The primary outcome will be the number of ICU-free days to day 14 (defined as the number days alive and outside of the intensive care unit in the first 14 days after enrollment).

Secondary outcomes

  1. Ventilator-free Days to Day 14

    Time frame: 14 days

    A secondary outcome will be the number of ventilator-free days (defined as the number of days alive and breathing unassisted after the final achievement of unassisted breathing before day 14)

  2. In-hospital Mortality to Day 14

    Time frame: 14 days

    A secondary outcome will be in-hospital mortality to day 14 (defined as the incidence of mortality prior to hospital discharge within 14 days after enrollment).

  3. Renal Replacement Therapy-free Days to Day 14

    Time frame: 14 days

    Renal replacement therapy-free days to day 14 (defined as the number of days alive and free of renal replacement therapy from the last receipt of renal replacement therapy after enrollment to study day 14)

  4. Highest Stage of Acute Kidney Injury

    Time frame: 28 days

    Highest stage of acute kidney injury as defined according to Kidney Disease Improving Global Outcomes (KDIGO) criteria Stage 0 (no acute kidney injury) Stage 1 Serum creatinine 1.5-1.9 times baseline or ≥0.3 mg/dl (≥26.5 mmol/l) increase or Urine output <0.5 ml/kg/h for 6-12 hours Stage 2 Serum creatinine 2.0-2.9 times baseline or <0.5 ml/kg/h for ≥12 hours Stage 3 Serum creatinine 3.0 times baseline or Increase in serum creatinine to ≥4.0 mg/dl (≥353.6 mmol/l) or Initiation of renal replacement therapy or in patients <18 years, decrease in eGFR to <35 ml/min per 1.73 m² or Urine output <0.3 ml/kg/h for ≥24 hours or anuria for ≥12 hours

  5. Highest Plasma Creatinine Between Enrollment and 28 Days After Enrollment

    Time frame: 28 days

    Highest plasma creatinine (mg/dL) between enrollment and 28 days after enrollment, censored at hospital discharge

  6. Receipt of Renal Replacement Therapy

    Time frame: 28 days

    receipt of renal replacement therapy between enrollment and the first of 28 days or hospital discharge
