The Effect of Rapid Fluid Challenge Under Pulmonary Artery Catheter Monitoring on Physiological Indexes of Patients With Septic Shock

Not Applicable
Conditions
Septic Shock
Interventions
Other: fluid chanllenge
Registration Number
NCT03661268
Lead Sponsor
Chengdu Fifth People's Hospital
Brief Summary

Fluid challenge is often carried out in septic shock patients. Its responsiveness usually requires invasive monitoring. The pulmonary artery catheter(PAC) is the most effective means of monitoring.To use non-invasive methods is very tempting. Investigators hypothesize that venous-to-arterial carbon dioxide difference,venous-to-arterial carbon oxygen difference, central venous-arterial carbon dioxide to arterial-venous oxygen content ratio and Central Venous SO2 variations provides feasible estimation on fluid responsiveness in septic shock patients.

GroupInterventionDescription
Septic shockfluid chanllengePatients (at least 18 years of age, no more than 75 years old) with refractory hypotension secondary to sepsis who, at the discretion of treating physicians, required fluid challenge in the presence of pulmonary artery catheter. Refractory hypotension was defined as need of vasopressors to maintain systolic blood pressure (SBP) no less than 90 mmHg despite adequate fluid resuscitation.
Primary Outcome Measures
