Clinical Trial Summary

A randomized controlled clinical trial. 24 adult ICU patients will be recruited upon decision to administer fluid bolus of 500ml of crystalloid. The fluid will then be randomized to be infused at controlled room temperature or warmed to body temperature. Hemodynamic measurements will be made for 2 hours following the bolus, and laboratory values will be noted. The hypothesis is that part of the hemodynamic response will differed in response to cooling, and be larger in the cold group.


Clinical Trial Description

A randomized controlled clinical trial of the influence of fluid temperature on hemodynamic effects of fluids. 24 adult ICU patients meeting objective criteria of circulatory impairment (hypotension, tachycardia, lactatemia etc) will be recruited upon decision to administer fluid bolus of 500ml of crystalloid. The fluid will then be randomized to be infused at controlled room temperature of 22 degrees or warmed to body temperature at 38 degrees. All patients will be monitored with either calibrated or uncalibrated pulse contour analysis. Hemodynamic measurements (Heart rate (HR), Systolic blood pressure (SBP), Diastolic blood pressure (DBP), Mean arterial pressure (MAP), Cardiac output (CO), Cardiac index (CI), Stroke volume (SV), Stroke volume variation (SVV), Extravascular lung water (EVLW) etc) will be registered for 2 hours following the bolus, and laboratory values such as lactate, creatinine will be noted, as well as fluid balances. Confounders such as levels of vasopressors, sedation, switches in positioning och or ventilation will be registered. The hypothesis is that part of the hemodynamic response will differed in response to cooling, and be larger in the cold group. ;
