Study of Capillary Refill Time and Perfusion Index to Monitor Tissue Perfusion in Critically Ill Adults

What this Trial Is About

Researchers are studying the relationship between capillary refill time CRT and perfusion index PI in critically ill patients to improve tissue perfusion monitoring. CRT is a standard method involving pressing the skin to observe color return time, but it is not standardized and can be time-consuming. The trial aims to find a more precise and efficient way to monitor tissue perfusion by comparing CRT with PI, which is automatically measured by a pulse oximetry sensor worn continuously on the finger. The study involves observing patients using two monitoring methods CRT measurements performed manually and continuous automatic PI measurements. These methods will be compared to establish a correlation between the two indicators. The research takes place during the patients admission and early management of hemodynamic instability. No additional treatments or interventions are given, as this is an observational study. Participants will be adults admitted within 24 hours or experiencing hemodynamic instability requiring support. Researchers will measure CRT and PI to determine the PI threshold linked to abnormal CRT. The study requires no extra procedures beyond these assessments and monitoring, with participant involvement focused on data collection during routine care. The study is scheduled to run until May 2027.
