What did we learn last year?
in the eyes of the coagulation specialist“6% isooncotic hetastarch is better than gelatin”

Rainer Gatz, Herlev, Denmark -november 2012
“colloids in general are not better than crystalloids in ICU patients “
“but seem to be better in severe sepsis, cardiac surgery and liver cirrhosis “

What did we learn last year?
“albumin is better for patients with liver disease““and seems to be beneficial in sepsis“

"The apparent space of distribution in non-ascitic subjects averaged about 2.5 times the plasma volume.
Two apparent rates of transfer between plasma and extravascular spaces
with half times of approximately 3 and 24 hours, were observed."

albumin - transmembrane transportalbondin
Albondin-mediated capillary permeability to albuminSchnitzer JE, Oh PJ Biol Chem 1994 Feb 25;269(8):6072-82
"About 50% of albumin transport is dependent on binding to the endothelial cell surface glycoprotein, albondin.
The remaining, binding- and concentration-independent transport could occur through intercellular junctions and/or
fluidphase transport via vesicular transcytosis and/or transendothelial channels."

"Despite over 60 years of clinical practice, the safety and efficacy of gelatin cannot be reliably assessed in at least some settings in which it is currently used."

- primary outcome results: factors independently associated with renal dysfunction:
- male gender- increase in SAPS II scores- being a surgical patient- no decrease in SOFA scores during the first 24
hours- being treated during the interventional period of
the study factors independently associated with renal replacement therapy:
- need for vasopressors- baseline value of plasma creatinine
- secondary outcome results: mortality rate in patients with renal dysfunction versus in those without renal dysfunction (48% versus 24%, P < 0.01) mortality rate in patients requiring RRT 52% versus 26% in those not requiring RRT (P < 0.01)

Use of colloids
315 of 388 patients received colloids
association with renal dysfunction (no versus yes):185 (78%) versus 101 (86%) P=0.07
association with renal replacement therapy (no versus yes):241 (81%) versus 74 (82%) P=0.82
“Despite being used in more than 80% of patients with severe sepsis and/or septic shock, the administration of HES 130/0.4 in the first 24 hours of management was not associated with the occurrence of renal dysfunction.”

Ho-hum - elderly patients in first world ICUs don't differ whether treated with crystalloid or colloid. Still want to know
how to apply this to a 25 year old with a 3 day old perf appendix or in a 25 year old who blows up like a
Michelin Man on Ringer's but maintains normal body weight (and most other parameters) on starch (or gelatin back in the
day).

I see such patients and don't use HES and they don't bloat.You are overtreating with crystalloids in that case. 1 liter of HES
cannot miraculously make a patient less bloaty.

“Conclusion:The implementation of a chloride-restrictive strategy in a tertiary ICU was associated with a significant decrease in the incidence of AKI and use of RRT.”
0.7 l of gelatin per patient in the control period, no artificial colloids administered during the intervention period 154 / 120

succinylated gelatin (as used in this study) contains Na / Cl 154 / 120 mmol/l, is thus naturally "balanced"

Consensus statement of the ESICM task force on colloid volume therapy in critically ill patients
Konrad Reinhart, Anders Perner, Charles L. Sprung, Roman Jaeschke, Frederique Schortgen, A. B. Johan Groeneveld, Richard Beale and Christiane S. HartogIntensive Care Medicine Volume 38, Number 3 (2012), 368-383
We recommend not to use HES with molecular weight >=200 kDa and/or degree of substitution >0.4 in patients with severe sepsis or risk of acute kidney injury
and suggest not to use 6% HES 130/0.4 or gelatin in these populations. We recommend not to use colloids in patients with head injury and not to administer gelatins and HES in organ donors.We suggest not to use hyperoncotic solutions for fluid resuscitation. We conclude and recommend that any new colloid should be introduced into clinical practice only after its patient-important safety parameters are established.
