Brief Summary

Background: After hypotension, oliguria (urine output less than 0.5 mL/kg/h) was the most common trigger to administer fluid bolus in a multinational practice survey in intensive care. The effect of fluid bolus on cardiovascular variables can be very short-lived among patients in shock suggesting that fluid boluses in the optimization phase are unlikely to improve patient-centered outcomes. Moreover, a growing body of evidence suggests a poor renal response to fluid bolus. Objective: To investigate, whether fluid bolus - as a standard of care - improves urine output in oliguric patients compared to a non-interventional follow-up approach without fluid bolus. Design: Investigator-initiated, open, randomized, controlled study Interventions:

  1. 1.Intervention group - follow-up without intervention
  2. 2.Control group - fluid bolus (500mL of balanced crystalloid over 30 minutes)

Outcome Measures

Primary Outcomes (1)

  • Change in individual mean cumulative urine output (mL/kg/h)

    Doubling of the urine output is defined as clinically meaningful response

    2 hours after randomization compared to urine output 2 hours preceding randomization

Secondary Outcomes (3)

  • The difference between groups in the change in individual urine output

    2 hours after randomization compared to urine output 2 hours preceding randomization

  • Duration of consecutive oliguria (urine output <0.5 mL/kg)

    during ICU stay, i.e. as long as urine output stays below 0.5 mL/kg/h while the patient is in the ICU (an average of 5 to 7 days) or until renal replacement therapy is commenced

  • Cumulative fluid balance

    six hours from randomization

Other Outcomes (7)

  • Number of patients receiving rescue boluses and the number of rescue boluses

    study intervention period (i.e. 2 hours)

  • Highest stage of acute kidney injury

    within 24 hours, 48 hours and during ICU stay (an average of 5 to 7 days or up to 30 days if patient is still in ICU)

  • Number of patients with one or several protocol violation(s) and number of those per patient

    study intervention period (i.e. 2 hours)

  • +4 more other outcomes

Study Arms (2)

follow-up without intervention

EXPERIMENTAL

No intervention to increase the urine output within 2 hours will be done.

Other: follow-up without intervention

Standard group - fluid bolus

ACTIVE COMPARATOR

Patient will receive 500mL of balanced crystalloid intravenously over 30 minutes.

Other: fluid bolus

Interventions

follow-up without intervention
Standard group - fluid bolus

Eligibility Criteria

Age18 Years - 100 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Age over 18
  • Emergency admission to an ICU
  • Mean arterial pressure (MAP) \>65 mmHg (with vasopressors if needed) and initial fluid resuscitation for shock/hypovolemia has been given
  • Oliguria (urine output less than 0.5mL/kg/h) for at least 2 consecutive hours

You may not qualify if:

  • Marked fluctuations in hemodynamics within last 2 hours (cardiac arrhythmias, increase in norepinephrine need over 0.2ug/kg/min, need for initiation of inotrope/inodilator)
  • Administration of furosemide within last 6 hours
  • Chronic kidney disease (estimated pre-critical illness GFR \< 60ml/min/1.73m2)
  • Renal replacement therapy
  • Among patients with acute kidney injury, urgent indications for commencing renal replacement therapy
  • Fluid overload (cumulative fluid accumulation exceeds 10% of baseline body weight)
  • Pulmonary edema (bilateral infiltrates in chest x-ray)
  • Active bleeding (need for transfusion, platelets, or fresh frozen plasma)
  • Suspected or known intra-abdominal hypertension (IAP \>16mmHg)
  • Pregnant or lactating
  • Expected survival less than 24h
  • Obtaining informed consent is not possible/consent is denied
