FEAST Study(Fluid Expansion as Supportive Therapy)NEJM June 30, 2011 Maitland et al

Severe febrile illness & impaired perfusion randomised to: Bolus 5% Albumin 20-40ml Bolus 0,9% Saline No bolus

Halt recruitment 3141/3600 48hour mortality 10.6% bolus vs 7.3% non-bolus(p=0.003)

Criticisms - NEJM Oct 6, 2011 Severely anaemic children - 32% Hb<5mg/dl Acute haemodilution in pre-existing anaemia Impaired oxygen delivery leading to organ failure Malaria – 57% thus have sequestration of red

cells in microcirculation Shock – not all forms are the same – related to

high CO or diminished O2 Compromised oxygen delivery – 77% thus

worsening cellular dysoxia Malnutrition

Plans Rapid triage and treatment Monitoring in a low resource setting

What is possible? CVP What is physiologic fluid best for bolusing

Blood vs fluid boluses Choice of fluids BMJ 2010;341 Maitland, Colloids vs Crystalloids for fluid resuscitation Cochrane 2012 –

Perel P

Low-volume fluid resuscitation insufficient for patients in shock – Inotropes?

Page 22: Putting it all together: When resources are scarce Mignon McCulloch Associate Professor Department of Paediatric Critical Care Red Cross Children’s Hospital.

Needed:Observational Trial in Septic Shock

Fluid challenge – 10-20ml/kg…then Observe response:

Heart rate and BP, Resp rate, Oxygen sats Cardiac output in response to fluid

Portable Uscom/Echocardiography validation Pulmonary oedema – Lung impedance High flow Oxygen/CPAP/Ventilation Inotropes – peripheral/central

AKI???

Renal Replacement Therapy

What we have done in Cape Town?

Page 24: Putting it all together: When resources are scarce Mignon McCulloch Associate Professor Department of Paediatric Critical Care Red Cross Children’s Hospital.

Initial Management Urine output:

Aim for > 1ml/kg/hr Fluid challenge

10ml/kg 0.9% Saline over 30 minutes and reassess urine output

If no improvement & no signs of fluid overload, repeat bolus

Clinical assessment regarding intravascular volume status +/- invasive assessment

“Encouraging Agents” Fluid and Perfusion Furosemide ivi

Boluses 1 - 5mg/kg or Infusion 0.1 – 1mg/kg

Mannitol/Metolazone Aminophylline 1 - 5mg/kg ivi if stable **Dopamine 2 – 5mcg/kg/min infusion

Tips for Success Size matters…keep skin nick at minimum or nil at all

Else will leak!!! Avoid metal needle that comes with pack

Rather Jelco/Venous access catheter Withdraw needle 0.5mm as go thru peritoneum and

advance plastic sheath Run fluid in freely to fill abdomen before wire and

catheter If not free-flowing pull needle back slightly May be in bowel?....role of ultrasound Don’t forget to empty bladder

CONCLUSION

Peritoneal dialysis as a form of acute renal replacement therapy is: Practical Appropriate for developing countries

Results reflected suggest that due to ease of use, it may also be appropriate for centers where access to CVVH/D may not be available due to lack of equipment or trained staff
