Abstract

Background: Acute kidney injury (AKI) is a serious complication of cardiogenic shock or septic and main surgery in thirty to fifty-seven percent of critically ill intensive care patients. AKI manifests itself early through renal vasoconstriction.

Objective: To evaluate the RRI as an indicator of AKI in critically ill patients and determine the optimal therapeutic and prevention modality for kidney perfusion.

Patients and Methods: This cross-sectional research was performed on 100 critically ill cases who went to the intensive care unit at Al-Zahraa University Hospital between December 2021 and November 2022. Two groups of patients were performed relating to renal resistive index (RRI) (Doppler ultrasound was done and RRI measured within 24 hours of admission), Group I: sixty cases with normal RRI, and Group II: 40 cases with high RRI.

Results: There was a significant positive correlation among RRI & s. urea (r=0.513, p=0.000), s. creatinine at the day of admission (r=0.729, p=0.000) and three consecutive days follow-up (r=0.221, p=0.049), HbA1c (r=0.356, p=0.001), potassium (r=0.729, p=0.000), and there was a high significant positive correlation among RRI & critical ill patient scoring system Acute Physiology And Chronic Health Evaluation APACHE II score (r=0.729, p=000). There was a significant negative correlation between RRI and Hb (r=-0.271, p=0.015).

Conclusion: Renal resistive index is a potentially useful tool for detecting AKI in critically ill cases. In the presented study, RRI is more in patients with AKI than in those without AKI.
