Implications of EGDT triad trialsBackdrop: All patients received
– Early Identification
– Aggressive Fluid Resuscitation (about 4-5 liters in first 6 hours)
– Early antibiotics (>97% all groups)
– Other care elements provided
1. A team based EGDT protocol or empiric structured protocol was not beneficial compared to usual care in 2009 - 2013
2. Systematic Screening and Aggressive treatment is needed to reproduce these findings
What EGDT does not tell us:
“How much fluids should I give to a septic patient?”
…..While EGDT trials used fluids, they were not fluids trials
The Pendulum is Swinging

Too Little
Fluid
Each Has Theoretical AdvantagesLiberal Fluids Restrictive Fluids
Augment preload to increase CO and organ perfusion
Reduce overall fluids and positive fluid balance
Decrease vasopressor use and its detrimental effects
Early vasopressors to treat vasodilation
?Increase Microcirculatory Flow Prevent worsening of pathologic edema(due to sepsis-induced barrier dysfunction)
Negative Fluid Balance is Associated with Better Outcomes
Pre-EGDT = Conservative
Post EGDT = Liberal

How much fluids should we give a patient before moving on to
vasopressors?
Crystalloid Liberal Or Vasopressors Early Resuscitation in Sepsis
(CLOVERS)
PETAL Network
Hypothesis
“Conservative”(Vasopressors for followed by rescue fluids)
Versus
“Liberal”(Fluids followed by rescue vasopressors)
Will reduce 90-day in-hospital mortality in Sepsis induced hypotension
Methods
• Multicenter, randomized prospective phase 3 trial
• Sepsis induced hypotension
• Intervention 24-hour fluid titration strategies
• 2,320 patients planned enrollment
• 50 PETAL network hospitals
• Primary outcome: 90-day inpatient mortality
What is the correct “dose” and
“timing” intravenous fluids in
sepsis-induced hypotension?
Questions?
Inclusion Criteria
• A suspected or confirmed infection
• SBP< 100 mmHg or MAP < 65 mmHg after a minimum of at least 1 liter of fluid
Exclusion Criteria (abbreviated)
• Age < 18 years
• Patient already received 3 liters of fluid
• >4 hours elapsed since meeting criteria
• Blood pressure is at known baseline
• Pulmonary edema or signs of new fluid overload
• Physician unwilling to randomize to one of the arms
