Introduction: The primary objective was to determine the incidence of glomerular hyperfiltration (GHF) in a population of patients admitted for severe trauma in the intensive care unit (ICU). The secondary objective was to compare creatinine clearance (CrCl) with results from the Jelliffe, CockCroft-Gault and T-MDRD equations.
Methods: Prospective observational study that includes patients admitted in ICU with a diagnosis of severe trauma. CrCl was measured in a 4-hour sample on the third day of admission. Patient demographics and injury severity score (ISS) are collected. GHF was defined as CrCl> 130 ml / min / 1.73 m2.
Results: 20 patients were included with 52.8 ± 17.7 years, 75% male, and ISS 25.4 ± 7.2. The incidence of GHF measured by clearance was 75% on the third day of admission and was more common in women (100%) than in men (66.6%) with values ranging between 131 and 226 ml/min/1.73 m2. The data provided by the equations underestimated the clearance in 90% of the cases, finding the highest concordance with T-MDRD, which detected 43.7% of the patients with GHF.
Conclusions: The incidence of GHF in patients with severe trauma is high in the first week of admission. The compared formulas show important deviations with respect to CrCl. In case of using an estimating equation, we recommend T-MDRD, although in most cases the real value is underestimated.
