Detection of Sepsis Occurrence by Using Blood Fluorescence

Overview

This study adopted a case-control study method to explore a reagent-free, highly sensitive, and frequently screened blood fluorescence metabolite analyzer for sepsis, which can detect the emergence of inflammatory free radicals before organ damage and shorten the diagnosis time of sepsis.

Currently, clinical practice lacks an effective screening method for early detection and prediction of sepsis. This gap hinders timely differential diagnosis, leading to severe shock and increased mortality rates. Although the qSOFA score is highly specific, it is not devoid of false negatives. Typically, by the time sepsis is confirmed using the qSOFA (≥ 2) and SOFA (≥ 2) scores as gold standards, the patient may already be suffering from organ damage, thus escalating the risk of death. Early-stage septic patients exhibit a surge in inflammatory free radicals, altering the optical characteristics of their blood compared to that of healthy individuals. Based on this, we hypothesize that a blood fluorometer could detect these early changes in septic patients, enabling rapid and accurate diagnosis to mitigate mortality rates. This study will conduct a case-control investigation, collecting blood from both admitted and discharged patients, with the aim of developing a reagent-free, highly sensitive blood fluorescence metabolite analyzer. This device will be capable of frequent sepsis screenings, detecting inflammatory free radicals before organ damage occurs, thereby reducing the time to sepsis diagnosis.
