Comparison of three formulas to evaluate acute renal failure in preeclamptic puerperal women

Evaluamos fórmulas para calcular la tasa de filtración glomerular en casos de pacientes obstétricas atendidas en la unidad de cuidados intensivos.Introduction: Acute renal failure in puerperal women who have suffered preeclampsia and HELLP syndrome has been scarcely studied. Aim: to compare the Cockroft-Gault, Modification of Diet in Renal Disease, and Chronic Kidney Disease Epidemiology Collaboration equations with the 24 hour creatinine clearance formula in puerperal women. Materials & Methods: This was an observational study. The selected formulas were calculated at 1, 8, 16 and 24 hours after delivery. Pearson correlation and Bland-Altman tests were performed. Results: 38 patients (mean age 26.4 years) were included. The three highest correlation coefficients with the 24 h creatinine clearance were the Modification of Diet in Renal Disease at 8 hours (r² = 0.920), and the Chronic Kidney Disease Epidemiology Collaboration equation at 24 (r² = 0.847) and 16 hours (r² = 0.842) post-delivery. Conclusion: In puerperal women who have suffered preeclampsia and HELLP syndrome, the Chronic Kidney Disease Epidemiology Collaboration equation shows more consistent results the first 24 hours post-delivery
