Brief Summary

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

Brain death is a complex and irreversible condition marked by the cessation of all brain activity. This retrospective study analyzes ICU patients who progressed from initial brain injury to brain death. The research focuses on demographic profiles, pharmacological interventions, laboratory data, and imaging findings to understand these cases clinical trajectories and therapeutic responses. Central to this study is evaluating cardiovascular support using the Vasoactive-Inotropic Score (VIS) and Total Inotrope Exposure (TIE) Score. This study explores the relationship between the etiology of brain death and the pharmacologic cardiovascular support administered, as quantified by VIS and TIES scores. This study seeks to enhance the management strategies and improve outcomes for patients diagnosed with brain death

Detailed Description

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

This study undertakes a comprehensive retrospective analysis of patients admitted to the intensive care unit (ICU) with an initial diagnosis of brain injury who subsequently progressed to brain death. The investigation will meticulously assess these patients, demographic profiles, pharmacological interventions, laboratory parameters, and radiological imaging findings. The overarching aim is to delineate the clinical trajectory and therapeutic responses of patients diagnosed with brain death, critically evaluating the complexities encountered during their management, and providing evidence-based insights to inform future treatment protocols.

Central to this study is the quantitative assessment of hemodynamic stability using the Vasoactive-Inotropic Score (VIS) and the Total Inotrope Exposure (TIE) Score. The VIS will quantify the need for vasopressor and inotropic support, reflecting the severity of cardiovascular instability. At the same time, the TIE Score will measure the cumulative exposure to inotropic agents, providing a comprehensive evaluation of the overall cardiovascular burden. The primary aim of this study is to explore the relationship between the etiology of brain death and the pharmacologic cardiovascular support administered, as quantified by VIS and TIES scores. Additionally, the study will assess how these pharmacologic interventions differ in patients who have undergone decompressive surgery compared to those who have not.

This thesis aspires to make a significant contribution to the optimization of management strategies for patients diagnosed with brain death, aiming to enhance clinical decision-making and improve patient outcomes in this critically ill cohort.
