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.Intervention group - follow-up without intervention
- 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
EXPERIMENTALNo intervention to increase the urine output within 2 hours will be done.
Standard group - fluid bolus
ACTIVE COMPARATORPatient will receive 500mL of balanced crystalloid intravenously over 30 minutes.

Eligibility Criteria
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
