Summary

Haemodynamic optimization is of paramount importance in septic shock, but is really consensual and standardized during the first 6 hours of treatment. Haemodynamic treatment including fluid loading management, vasoactive treatment and oxygen transport optimization is mainly based on expert recommendations or non-randomized trials. Recently, preload dependence indexes such as pulse pressure variation have been shown to be more accurate to predict fluid responsiveness than static indexes such as filling pressures. However, whether using preload dependence indexes changes septic shock prognostic remains to date unknown. The aim of this non-blinded randomized controlled trial is to assess whether haemodynamic optimization using preload dependence indexes and pulmonary thermodilution 1. reduces septic shock duration assessed by administration duration of vasoactive treatment (primary end point), 2. reduces regional hypoperfusion assessed by arterial lactate, 3. reduces lung hydrostatic oedema linked to excessive fluid loading (assessed by PaO2/FIO2 ratio and extravascular lung water). 4. reduces organ dysfunction (assessed by the SOFA score), ICU stay and 7 and 28 day mortality Control group is managed with an algorithm using filling pressures to drive haemodynamic treatment.

Conditions

  • Septic Shock

Interventions

DRUG

FLUID MANAGEMENT GUIDED WITH PRELOAD-DEPENDENCE PARAMETERS (VOLUVEN ®)

in this arm, fluid loading is administered with an algorithm using preload dependence indexes. This algorithm is used every hour during the first 6 hours after inclusion, then every 4 hours until vasopressor weaning, and whenever mean arterial pressure fell below 65 mm Hg. Fluid loading is performed with cristalloids or colloids at the discretion of the attending physician.

DRUG

STANDARD-GUIDED FLUID MANAGEMENT (VOLUVEN ®)

in this arm, fluid loading is administered with an algorithm using central venous pressure. This algorithm is used every hour during the first 6 hours after inclusion, then every 4 hours until vasopressor weaning, and whenever mean arterial pressure fell below 65 mm Hg. Fluid loading is performed with cristalloids or colloids at the discretion of the attending physician.
