Septic Shock Clinical Trial
Official title:
Comparison of a Tissue Perfusion Guided Hemodynamic Protocol With a Conventional Hemodynamic Protocol in Septic Shock Patients: a Prospective, Randomised, Controlled Study
The Surviving Sepsis Campaign (SSC) published 2008 revised guidelines to improve survival of septic shock patients. For hemodynamic stabilization the SSC recommends distinct treatment goals. The study hypothesis is that a tissue perfusion guided protocol could reduce the duration on vasopressor treatment compared to a conventional protocol.
Background
Septic shock is a frequent and severe entity with a mortality of 55%. The Surviving Sepsis
Campaign (SSC) published 2008 revised guidelines to improve survival of septic shock
patients.
For hemodynamic stabilization the SSC recommends as treatment goals a mean arterial blood
pressure > 65mmHg (MAP), a central venous blood pressure of 8-12 mmHg, a mixed venous oxygen
saturation >65%, a central venous oxygen saturation > 70% and a diuresis > 0.5 ml/kg/h (1).
According to the SSC guidelines a MAP > 65 mmHg should be aimed because at this blood
pressure level tissue perfusion is preserved. This is based on a study in ten septic shock
patients where norepinephrine was titrated to three levels (65, 75 and 85 mmHg) and the
authors concluded that parameters of tissue perfusion did not differ between the each level
(2).
Objective
To evaluate if a hemodynamic protocol guided by parameters of tissue perfusion could reduce
the duration of vasopressor treatment in septic shock patients.
Methods
Patients suffering from septic shock requiring vasopressor support are randomly assigned to
a control group (usual care) and an intervention group (tissue perfusion guided protocol).
In the intervention group parameters of tissue perfusion are used to guide hemodynamic
therapy.
