Background: To study AKI among children admitted in ICU. Materials & methods: A total of 150 subjects were enrolled. The subjects were divided as two groups AKI as 50 in number and non- AKI as 100 subjects. The relevant risk factors or outcomes of AKI: age at PICU admission, gender, requirement for mechanical ventilation during PICU admission, admission diagnosis of trauma, duration of mechanical ventilation, and PICU mortality. Results: A total of 150 subjects were enrolled. The subjects were divided into two groups as AKI and Non- AKI patients. Patients with AKI had approximately double the duration of PICU and of mechanical ventilation compared to non-AKI patients. Conclusion: AKI is associated with increased mortality and morbidity in critically ill children.
