Overview
Critically ill patients are at high risk of developing acute kidney injury (AKI). Lithium is freely filtrated at the glomerulus and almost completely reabsorbed in the proximal tubule, which provides a quantitative estimation of proximal tubule reabsorption. The investigators hypothesized that endogenous lithium reabsorption is impaired in the early stages of critical illness.
Investigators would like to study 10 ICU patients with AKI diagnosed, 10 patients without AKI, and 10 healthy controls.
Description
Blood and urine samples will be obtained at 08:00, 14:00 and 20:00 during one day. Renal clearance of creatinine (CCr) and lithium will be calculated.
Eligibility
Inclusion Criteria:
- ICU patients diagnosed with AKI, without AKI and healthy controls
