EGDT
In-hospital mortality• 46.5% vs 30.5% (NNT = 6!)
60-day mortality• 56.9% vs 44.3%
EGDT got more early fluid, pRBC, inotropes

Why are patients in hypovolemic shock?• Venodilation• 3rd spacing• Losses (vomiting, diaphoresis)• Recent poor PO intake

EGDT• If ScvO2<70% and hct<0.30
TRICC • If Hb > 70g/L
How does this help?
O2 content = (1.34 x Hb x SaO2) + (0.0031 x PO2)
NEJM 1999;340:409
Results• No difference in 30 or 60 day mortality• Restrictive group
• Lower in-hospital mortality 22.2% vs 28.1% (p=0.005)
• Less sick pts (APACHE II score <20) did better• ARR 7.4% (95%CI 1.0 – 13.6%)
• No difference in mortality in sepsis sub-group
EGDT• Hypovolemic ED patients• Actual measurement of suboptimal O2
delivery TRICC
• Euvolemic pts enrolled within 72 hours of ICU admit
• 6% sepsis, 27% had any infection

Mohammed 2006, Ray 2007, Riche 2007• Studies designed for etomidate vs no etomidate• No increase in mortality
CORTICUS (2008)• >28d mort with one dose (OR 1.53 (1.06-2.26)) • Etomidate non-randomized, post-hoc analysis
Bottom line• Avoid in sepsis
