Putting it all together:When resources are scarce Mignon McCulloch Associate Professor Department of Paediatric Critical Care Red Cross Children’s Hospital (RXH) University of Cape Town
Acknowledgements • Thanks to Stuart and Tim • Including all forms of CRRT • Disclosures • Passionate about PD • Access for children with AKI in poorly resourced areas
2.5kg boy Complex Congenital Heart Post-op surgical No urine output x 8hrs What next? 12year old boy Meningococcal Sepsis Shocked needing inotropic support Poor urine output x 12hrs What next? Clinical Patients
Role of Fluid • FO >20% @ time of CRRT initiation %FO = (Fluid In – Fluid Out) x 100% (PICU Admission weight) Goldstein et al(2005). KI 67:653-658 • But what happens before?
Goal directed therapy Study of Emergency Department Management
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?
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?
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

Challenges on Return • Poor Staffing 100% • Lack of Facilities & Equipment 86% • Radiology – Ultrasound only 86% • Support from Home Institutions 71% • Histology support 57%
ISN Sister Program PD Workshop Accra, Ghana 04.12.2011
PD Catheters • Art of Medicine?Innovative and Creative • Cannulas • Naso-gastric tubes/Chest Drains • Venous Central lines • Rigid ‘Stick’ catheters • ‘Peel away’ Tenchkoff • Flexible Multi-purpose drainage catheters • Auron A et al Am J Kidney Dis 2007
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
