Crystalloid Liberal or Vasopressors Early Resuscitation in Sepsis
Multicenter, prospective, phase 3 randomized non-blinded interventional trial of fluid treatment strategies in the first 24 hours for patients with sepsis-induced hypotension. The aim of the study is to determine the impact of a restrictive fluids strategy (vasopressors first followed by rescue fluids) as compared to a liberal fluid strategy (fluids first followed by rescue vasopressors) on 90-day in-hospital mortality in patients with sepsis-induced hypotension.
- Septic Shock
- Eligible Ages
- Over 18 Years
- Eligible Genders
- Accepts Healthy Volunteers
- Age ≥ 18 years
- A suspected or confirmed infection (broadly defined by administration or planned administration of antibiotics)
- Sepsis-induced hypotension defined as systolic blood pressure < 100 mmHg or MAP < 65 mmHg after a minimum of at least 1 liter of fluid (*Fluids inclusive of pre-hospital fluids; blood pressure must be below any known or reported pre-morbid baseline).
- More than 4 hours elapsed since meeting inclusion criteria or 24 hours elapsed since admission to the hospital
- Patient already received 3 liters of intravenous fluid (includes prehospital volumes)
- Unable to obtain informed consent
- Known pregnancy
- Hypotension suspected to be due to non-sepsis cause (e.g. hemorrhagic shock)
- Blood pressure is at known or reported baseline level
- Severe Volume Depletion from an acute condition other than sepsis. In the judgment of the treating physician, the patient has an acute condition other than sepsis causing (or indicative) of *severe volume depletion; Examples include: Diabetic ketoacidosis, high volume vomiting or diarrhea, hyperosmolar hyperglycemic state, and nonexertional hyperthermia (heat stroke); severe is defined by the need for substantial intravenous fluid administration as part of routine clinical care
- Pulmonary edema or clinical signs of new fluid overload (e.g. bilateral crackles, new oxygen requirement, new peripheral edema, fluid overload on chest x-ray)
- Treating physician unwilling to give additional fluids as directed by the liberal protocol
- Treating physician unwilling to use vasopressors as directed by the restrictive protocol.
- Current or imminent decision to withhold most/all life-sustaining treatment; this does not exclude those patients committed to full support except cardiopulmonary resuscitation
- Immediate surgical intervention planned such that study procedures could not be followed
- Prior enrollment in this study

Primary Hypothesis: Restrictive (vs liberal) fluid treatment strategy during the first 24 hours of resuscitation for sepsis-induced hypotension will reduce 90-day in-hospital mortality.
1. We will emphasize early screening and protocol initiation, and enroll a maximum of 2320 patients with suspected sepsis-induced hypotension.
- All patients will receive at least 1 liter of fluids prior to meeting study inclusion criteria (and no more than 3 liters prior to randomization).
- Patients will be enrolled within 4 hours of meeting study inclusion criteria
- Any type of isotonic crystalloid (normal saline, ringers lactate, or a balanced solution such as plasmalyte) is permitted.
2. Restrictive Fluids (Early Vasopressors) Group
- Norepinephrine will be used as preferred vasopressor and titrated to achieve mean arterial pressure (MAP) between 65 mmHg and 75 mmHg
- "Rescue fluids" may be administered as 500ml boluses if predefined rescue criteria are met
3. Liberal Fluids (Fluids First)
- 2 liter infusion upon enrollment (may forego second liter if MAP/SBP and heart rate are normalized and clinical assessment if patient is fluid replete after the first liter).
- Administer 500ml fluid boluses for fluid triggers until 5 liters administered or development of clinical signs of acute volume overload develop
- "Rescue vasopressors" may be administered after 5 liters of fluid, for development of acute volume overload, or if other predefined rescue criteria are met
