Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is an investigator-initiated, multicenter, randomized, parallel-group, open-labeled, feasibility trial investigating volumes of fluid within 24 hours in 124 patients with sepsis allocated to two different IV fluid regimens enrolled at three emergency departments in Central Region Denmark. The primary outcome is total intravenous, crystalloid fluid volume within 24 hours and key secondary outcomes include protocol violations, total fluids (intravenous and oral) within 24 hours, SAEs/SUSARs, and inhospital-, 30- and 90-day mortality.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

BACKGROUND:

Sepsis is common in emergency department (ED) patients. Traditionally, intravenous (IV) fluids are used to optimise the circulation, and the use of higher volumes is recommended by international guidelines, but there are no recommendations for sepsis without hypotension or shock. Studies in septic shock seem to favour fluid restriction. Whether this is true in sepsis without hypotension/shock is unknown.

OBJECTIVES:

The aim of the REFACED Sepsis trial is to test if an IV fluid restrictive protocol in ED patients with sepsis is feasible, i.e., if the protocol decreases the IV fluid volumes administered.

DESIGN:

REFACED Sepsis is a multicenter, randomized, parallel-group, open-labeled, feasibility trial

POPULATION:

ED patients with sepsis expected to be admitted for ≥ 24 hours

EXPERIMENTAL INTERVENTION:

In the IV fluid restriction group no IV fluids should be given unless one of the below mentioned occurs;

A fluid bolus of 250 ml isotonic crystalloid may be given within 15 minutes if one of the following occurs (hypoperfusion criteria):

* Lactate concentration ≥ 4 mmol/l (arterial or venous blood gas/blood sample)
* Hypotension (systolic BP \< 90 mmHg)
* Mottling beyond edge of kneecap (i.e., Mottling score \>2)53
* Severe oliguria, i.e., diuresis \< 0.1 ml/kg/h, during the first 4 hours of admission

All patients will be ensured min. 1 L of oral/intravenous fluids in 24 hours and electrolytes can be corrected.

CONTROL INTERVENTION:

In the usual care group there will be no upper limit for the use of IV fluids.

OUTCOMES:

The primary outcome is 24-hour intravenous crystalloid fluid administration. Key secondary outcomes are: Feasibility measures: Number of patients with major protocol violations, Number of patients screened vs included, Time from admission to inclusion, Number of patients lost to follow up in terms of 24-hour fluids, Accumulated serious adverse reactions and events (SAEs + Suspected Unexpected Serious Adverse Reaction (SUSARs)) within 48 hours in-hospital, Total fluids (oral and intravenous) at 24 hours,

TRIAL-SIZE:

124 patients will be randomized to restrictive fluid administration or usual care within 24 hours of randomization

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Restrictive fluid administration

No IV fluids unless one of the extenuating circumstances occur;

1. In case of severe hypoperfusion or severe circulatory impairment defined by either: 1) Lactate≥4 mmol/L, 2) Hypotension (systolic BP \< 90 mmHg), 3) Mottling beyond the kneecap (mottling score \>2) OR 4) Urinary output\<0.1 mL/kg bodyweight/h (only in the first 4hrs after randomization) then a bolus of 250 ml of IV crystalloid solution may be given followed by re-evaluation
2. In case of overt fluid losses (e.g. vomiting, large aspirates,) IV fluid may be given to correct for the loss, but not above the volume lost.
3. In case the oral/enteral route for water or electrolyte solutions is contraindicated or has failed, IV fluids may be given to:

Correct dehydration or electrolyte deficiencies Ensure a total fluid input of 1 L in 24hrs
4. IV fluids may be given as carrier for medication, but with lowest possible volume

Group Type EXPERIMENTAL

Isotonic crystalloids

Intervention Type DRUG

Types of fluids in both intervention groups:

* Fluids used for electrolyte disturbances: Fluids should be chosen to substitute the specific deficiency
* Fluids given to substitute overt loss: Isotonic crystalloids are to be used. If large amounts of ascites are tapped, then human albumin may be used.
* Blood products are only to be used on specific indications including severe bleeding, severe anaemia and prophylactic in case of severe coagulopathy.

Usual care (standard care)

There will be no upper limit for the use of either IV or oral/enteral fluids

1. IV fluids should be given in the case of hypoperfusion or circulatory impairment and should be continued as long as hemodynamic variables improve including static or dynamic variable(s) as chosen by the clinicians. These criteria are based on the Surviving Sepsis Campaign guideline.
2. IV fluids should be given as maintenance if the ICU has a protocol recommending maintenance fluid
3. IV fluids should be given to substitute expected or observed loss, dehydration or electrolyte derangements
