Brief Summary

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

The purpose of this study is to determine whether the use of a 3-hour protocol utilizing non-invasive hemodynamic optimization treatment strategy results in better outcome and lower hospital costs in patients who present with severe bloodstream infections to the Emergency Department (ED).

Detailed Description

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

Severe sepsis is a syndrome where the body develops organ dysfunction secondary to uncontrolled inflammatory response to infection. Various resuscitation bundles have been formulated and practised to treat severe sepsis, such as early goal-directed therapy (EGDT). EGDT involves the insertion of invasive catheters in patients with severe sepsis or septic shock using serial measurements to guide therapy and achieve hemodynamic goals, such as mean arterial pressure (MAP), central venous pressure (CVP) and central venous oxygen saturation (ScvO2) by 6 hours. The drawbacks include the invasive nature of inserting these catheters with its complications and tedium to set up the equipment. A non-invasive approach using the Non-Invasive Cardiac Output Monitor (NICOM) and passive leg raising (PLR) maneuver to guide fluid and vasoactive agent therapy targeting fluid responsiveness and MAP may be able to achieve better outcome, measured by lactate clearance at 3 hours and at a lower hospitalization cost.

Study Groups

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

NICOM and PLR

A systematic approach to resuscitation started in the ED and using a step-wise approach to optimize cardiac preload, afterload, and contractility, thus optimizing oxygen delivery to the tissues will be applied to the intervention group using the Non-Invasive Cardiac Output Monitor (NICOM) and passive leg-raising (PLR) maneuver.

Group Type EXPERIMENTAL

NICOM

Intervention Type DEVICE

Assessment of fluid responsiveness will be done using the non-invasive cardiac output monitor (NICOM) and passive leg-raising (PLR) maneuver to target mean arterial pressure of between 65mmHg and 90mmHg; and change in stroke volume index (SVI) less than 10%, prior to administration of fluid boluses.

Usual care

Group Type ACTIVE_COMPARATOR

Usual care

Intervention Type OTHER

Usual care is given at the clinician's discretion in accordance with current best practice. Standard treatment may involve treatment with intravenous fluids, and medications to support the blood pressure and heart.
