Can Urinary Partial Oxygen Pressure be an Indicator of Acute Kidney Injury in Patients With Sepsis?

Study Overview
=================
Brief Summary
-----------------
The ability of bladder urinary partial pressure, measured as a reflection of renal medullary oxygen tension, which is an indicator of the development of acute kidney injury (AKI), to predict the development of AKI at an early stage.

Detailed Description
-----------------
Patients hospitalised in the intensive care unit with a diagnosis of sepsis will be followed up for the development of ABH. This follow-up will be performed for 5 days after hospitalisation. During this period, patients will be sampled for NGAL 5 times in total, once every day. PuO2 will be sampled daily to determine PuO2 and to observe the development of AKI, and in cases of hypotension where the mean arterial pressure falls below 65 mmHg or in cases of severe acidosis, extra will be sampled at least 5 times, once every day. PuO2 will be analysed in the blood gas device and PuO2 value will be recorded. For NGAL analysis, patient blood will be collected in ETDA tubes and stored at -80 °C until analysis. NGAL will then be measured by turbidimetric imminoassay method. The comorbidities of the patients will be questioned and recorded, the types and amounts of fluids taken, whether they received blood and blood products, and if so, which product and how much they received will be recorded. APACHI II score and SOFA scores of the patients at hospitalisation will be recorded. GCS, whether mechanical ventilation support is provided or not, if any, ventilation method, mode and ventilation parameters will be recorded. In addition to these, mean arterial pressure, pulse, temperature, SpO2, FiO2 values will be recorded clinically. Haemoglobin, haemotocrit, platelets, bun, creatinine, biluribins, liver function tests and arterial blood gas will be recorded in the laboratory. In addition, whether the patients have ARDS, whether they are receiving renal replacement therapy and if so, the prescription and ultrasonography findings will be recorded.
