About

Sepsis is a serious condition where the body's immune response to infection overreacts, leading to organ damage and death. Venous congestion, a buildup of blood in the veins, can occur in sepsis and contribute to organ injury. VExUS (Venous Excess Ultrasound Score) is an ultrasound method that can detect congestion early. This study examines whether ICU nurses, after training, can perform VExUS reliably, explores their experiences, and investigates links between VExUS findings and clinical outcomes.

Full description

Sepsis is a serious and potentially life-threatening condition that happens when the body's defense system overreacts to an infection. This overreaction can reduce the oxygen supply to the body's organs, causing damage and, in severe cases, organ failure. Up to 30% of people with sepsis die from it, and it is one of the most common causes of death in intensive care units.

Venous congestion, which means blood builds up in the veins, can occur in sepsis-for example, due to fluid overload or reduced heart function. This condition has been linked to organ injury. The VExUS (Venous Excess Ultrasound Score) is an ultrasound-based method that evaluates blood flow in the body's main veins. It has shown promise for identifying patients with venous congestion early. By using VExUS, it may be possible to detect the risk of organ injury sooner in intensive care patients with sepsis.

Ultrasound is becoming an increasingly important diagnostic tool in intensive care and is now often used directly at the bedside. Doctors already use ultrasound in many clinical situations and have extensive experience with it. Intensive care nurses, however, have had less opportunity to use ultrasound. Increasing their skills in this area could improve patient care.

VExUS is a relatively simple method that assesses blood flow in central veins without requiring precise measurements, making it well suited as an introduction to ultrasound use.

The purpose of this study is to examine whether intensive care nurses, after training, can perform VExUS on sepsis patients reliably. In the long term, this study could lead to intensive care nurses routinely performing VExUS as part of their hemodynamic assessment of patients.The study also explores the nurses' experiences and confidence with the method, including interviews. In addition, it investigates whether venous congestion identified by VExUS is linked to clinical outcomes.
