Transcutaneous pO2, Transcutaneous pCO2 and Central Venous SO2 Variations to Define Fluid Responsiveness
In Brief
A clinical study evaluating fluid challenge for Hypotension and 3 related conditions. Completed, enrolled 40 participants across 1 site.
Detailed Summary
Fluid challenge is often carried out in critical ill patients. Its responsiveness usually requires invasive monitoring. To use non-invasive methods is very tempting. Investigators hypothesize that transcutaneous pO2,transcutaneous pCO2 and Central Venous SO2 variations provide feasible estimation on fluid responsiveness in critical ill patients.

Timeline
Interventions
A bag of 500ml of normal saline or 4% gelatin (Gelofusine, B. Braun Medical (Suzhou) Company Limited, Suzhou, China) is infused within 15 minutes using a bag pressurized to 300 mmHg. All other treatments, including maintenance fluids, dose of vasoactive agents and ventilator settings, remain unchanged during the study period.
