Determinants of modality of management of acute kidney injury in children seen at a tertiary hospital in Nigeria

Le résumé fourni par la source

Background: The cost of taking care of children with acute kidney injury (AKI) is enormous and beyond the reach of many caregivers in sub-Saharan Africa which are largely resource poor. It is therefore imperative to determine those who may benefit from conservative management which is comparatively cheaper to the renal replacement therapy (RRT).Objectives: To determine the clinical characteristics of children who were offered conservative and renal replacement therapy and evolve the most statistically significant eligibility criteria. Methods: A descriptive crosssectional study of children presenting with AKI admitted into the Emergency Paediatric Unit (EPU) of the University of Ilorin Teaching Hospital (UITH) between January 2008 to December 2012 was carried out. Demographic, clinical, and laboratory data were collected. A serialblood chemistry and urine analysis were also obtained. A total of 22 cases of acute kidney injury were seen within the period. Fourteen were conservatively managed while eight underwent sessions of dialysis.Results: The age range for those who had conservative managementwas 4-17 years with a mean ±SD of 8.11±3.91 years while the corresponding value in those with renal replacement therapy was 1.5-16years with a mean ±SD of 9.68±5.54years. There was no statisticalsignificant difference in the highest serum potassium, urea andcreatinine. However, the lowest urine output was significantly differentamong the two groups (p< 0.05).Conclusion: Urine output could be used as an eligibility criterion todetermine children with AKI who will require renal replacement therapy or benefit from a trial of conservative management.
