Although fluid resuscitation is an essential treatment in many forms of circulatory shock, its benefits are variable, and its administration carries a risk of potentially harmful fluid overload.\n\nAssessment of fluid responsiveness generally relies on changes in cardiac output. However, the actual therapeutic objective is rather to improve tissue oxygen utilization, as reflected by oxygen consumption. Despite its physiological relevance, direct measurement of oxygen consumption remains complex and difficult to perform in routine clinical practice.\n\nCapillary refill time is a simple, rapid, non-invasive, and readily available marker of peripheral perfusion. It is associated with outcomes in patients with circulatory shock, and a capillary refill time-guided therapeutic strategy may improve outcomes in patients with septic shock.\n\nThis study hypothesizes that changes in capillary refill time following fluid resuscitation may predict changes in oxygen consumption induced by fluid administration. If confirmed, capillary refill time and its changes could be incorporated into the criteria used to assess the indication for fluid resuscitation in patients with shock. They would also provide additional physiological information regarding the relationship between peripheral perfusion and oxygen consumption.",[70,71,72],"Critically Ill Patients","Circulatory Shock","Ventilated Patients",[74,75,76,77,78],"ICU","Circulatory shock","Oxygen consumption","Fluid responsiveness","Capillary refill time","NOT_YET_RECRUITING","2026-09-22",{"date":82,"type":83},"2026-09-24","ACTUAL",{"date":85,"type":66},"2026-12-01",{"date":87,"type":66},"2027-12-01",{"name":5,"class":6},1]
