Perioperative GoalDirected Therapy
Protocol Summary
APPROVED
Evidence-based, perioperative Goal-Directed Therapy (GDT) protocols.
Several single centre randomized controlled trials, meta-analysis and quality
improvement programs have shown that perioperative GDT decreases postoperative
complications and hospital length of stay when compared to standard fluid
management.1-5
This summary describes the three main perioperative GDT strategies which have been
successfully used to decrease postoperative morbidity and length of stay:
- Stroke Volume (SV) optimization with fluid
- Oxygen Delivery Index (iDO2) optimization with fluid and inotropes
- Pulse Pressure Variation (PPV) or Stroke Volume Variation (SVV)
optimization with fluid
This summary does not recommend the use of any specific medical device, and the
choice of the treatment protocol is left at the discretion of the anesthesiologist in charge.

SV Protocol
Overview
Using the SV protocol consists in giving successive small (200-250 ml) fluid boluses until
the SV reaches a plateau value (the plateau of the Frank-Starling relationship).
Many single centre randomized controlled trials6-12 and a multicentre quality
improvement program,13 showing a decrease in post-operative complications or hospital
length of stay in the perioperative GDT group, were based on this protocol.
This protocol is now officially recommended by the National Institute for Clinical
Excellence in the UK and by the French Society of Anesthesiology & Intensive Care (SFAR).

iDO2 Protocol
Overview
Using a iDO2 optimization protocol consists first in optimizing SV with fluid, as described
in the SV protocol.
Once SV has been optimized with fluid, iDO2 is calculated. If iDO2 is <600 ml/min/m2 an
inotrope (dobutamine or dopexamine) is introduced to achieve the iDO2 goal of 600 ml/
min/m2.
Inotropes should not be used or must be discontinued (if already introduced) in case of
tachycardia, cardiac arrhythmia or ischemia.
Several single centre randomized controlled trials, showing a decrease in post-operative
complications or hospital length of stay in the perioperative GDT group, were based on
this protocol.14-19

PPV/SVV Protocol

Using a PPV/SVV optimization protocol consists in giving fluid to maintain these dynamic
parameters below a predetermined cutoff value.
Several single centre randomized controlled trials, showing a decrease in post-operative
complications or hospital length of stay in the perioperative GDT group, were based on
