Microcirculatory Guided Goal Directed Fluid Therapy in Septic Shock; a Feasibility Study

Microcirculatory Guided Goal Directed Fluid Therapy in Septic Shock; a Feasibility Study

Prospective single centre study to assess the feasibility of fluid resuscitation guided by macrocirculatory and microcirculation parameters in patients in the early stages of septic shock. The investigators will utilise a novel point of care tool to assess microcirculatory sublingual perfusion in patients with septic shock. This, in combination with conventional haemodynamic monitoring will determine the timing and volume of resuscitative fluid administration. The feasibility of this technique will be determined prior to embarking on a pilot RCT.

Inclusion Criteria:

Age > 18 years Within 6 hours of ICU admission Evidence of suspected or confirmed infection Serial Organ Failure Assessment (SOFA) score increase of 2 or more (assuming baseline 0 if no previous measures) Requiring vasopressor therapy to maintain a MAP > 65mmHg Lactate > 2 mmol/l despite initial fluid resuscitation Requirement for advanced haemodynamic monitoring (PiCCO system) in the opinion of the attending clinician

Exclusion Criteria:

Patients not expected to survive 24 h in whom the intent of treatment is palliative Patients in whom the primary cause of the shock state is cardiogenic
