Brief 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.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 40 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Screening
Study Start Date : September 2013
Actual Primary Completion Date : December 2015
Actual Study Completion Date : December 2015

Arm Intervention/treatment
Experimental: Septic shock
Adult patients (at least 18 years of age) with refractory hypotension secondary to sepsis who, at the discretion of treating physicians, required fluid challenge in the presence of invasive hemodynamic monitoring. Refractory hypotension was defined as need of vasopressors to maintain systolic blood pressure (SBP) no less than 90 mmHg despite adequate fluid resuscitation.
Other: fluid challenge
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.

Primary Outcome Measures :
  1. Fluid Responsiveness [ Time Frame: Immediately after fluid challenge, average 5 minutes ]
    Increase in cardiac index ≥ 10% after fluid challenge
