Brief Summary

The goal of this clinical trial is to find out if a personalized treatment approach can improve care for people with sepsis in the emergency department (ED). Sepsis is a life-threatening condition that happens when the body has an uncontrolled response to an infection. This can lead to low blood pressure, organ failure, and death if not treated quickly. Right now, most people with sepsis receive a standard amount of fluids to raise their blood pressure. But this one-size-fits-all approach can lead to fluid overload and other complications. Because each person responds differently, this study will test whether a more personalized treatment-based on how the heart responds to fluids-can lead to safer and more effective care. The study will include 188 adults who come to the ED at the University Medical Centre Groningen (UMCG) with suspected sepsis in need of hemodynamic resuscitation. Everyone in the study will receive fluids to support their blood pressure. Participants will be randomly assigned to one of two groups:

  • Personalized treatment group: Fluids and vasopressors (medications that raise blood pressure) will be given based on how the heart responds to each fluid dose. This response is measured using a non-invasive monitor that tracks stroke volume index (ΔSVI)-a measure of how much blood the heart pumps.
  • Standard care group: Fluids will be given based on current guidelines (30 milliliters per kilogram of body weight), as decided by the treating doctor. Researchers will compare how much fluid is given during the first 3 hours of care. They will also look at:
  • When and how much vasopressor medicine is used
  • How well blood pressure and circulation respond
  • Signs of organ recovery or damage
  • How long participants stay in the hospital
  • Any problems or side effects during treatment The researchers hope that this personalized approach will lead to using less fluid, starting vasopressors earlier, and helping people with sepsis recover more safely and quickly.

Outcome Measures

Primary Outcomes (1)

  • The volume of IV fluids in ml administered within the first three hours after study enrolment.

    The primary endpoint is the volume of IV fluids in ml administered within the first three hours after study enrolment.

    Up to three hours, after study enrolment.

Secondary Outcomes (22)

  • Length-of-stay in hospital/intensive care unit (ICU)

    Until hospital discharge, an average of 2 weeks

  • New onset organ failure

    Up to 48 hours after hospitalization

  • Fluid balance

    Up to three hours after hospitalization

  • Fluid resuscitation

    Up to 7 days after hospitalization

  • Time to recovery of hemodynamic stability

    The time interval from hospital admission until hemodynamic stability, measured in hours.

  • +17 more secondary outcomes

Other Outcomes (5)

  • Cost-effectiveness

    Up to 30 days after hospitalization

  • Starling SV monitor trends

    Up to three hours after hospitalization

  • Hemodynamic parameter trends

    Up to three hours after hospitalization

  • +2 more other outcomes

Study Arms (2)

Personalized SV-Guided Resuscitation

EXPERIMENTAL
Other: Personalized SV-guided resuscitation

Standard Care Resuscitation

ACTIVE COMPARATOR
Other: Standard Care Resuscitation

Interventions

Participants will receive an IV fluid bolus directly after inclusion. Next, measurement of the cardiac output change in response to the fluid bolus by the Starling SV will be used to determine fluid responsiveness. Vital parameters and fluid responsiveness will be used to guide hemodynamic resuscitation, consisting of IV fluids and/or vasopressors, during the first 3 hours.

Personalized SV-Guided Resuscitation

In the control group, IV fluid and vasopressor administration will be determined at the discretion of the physician and in accordance with currently available guidelines (e.g. Sepsis Surviving Campaign).

Standard Care Resuscitation
