Predictors of Acute Kidney Injury in Critically Ill Children Admitted to PICU.

Acute Kidney Injury

Predictors of Acute Kidney Injury in critically ill children admitted to PICU during one year.

Acute kidney injury (AKI) is defined by a sudden loss of excretory kidney function. AKI is part of a range of conditions summarized as acute kidney diseases and disorders (AKD), in which slow deterioration of kidney function or persistent kidney dysfunction is associated with an irreversible loss of kidney cells and nephrons, which can lead to chronic kidney disease (CKD). AKI is determined by increased serum creatinine levels \>0.3 mg/dl (a marker of kidney excretory function) and reduced urinary output \<0.5 ml/Kg for more than 8 h (a quantitative marker of urine production) and is limited to a duration of 7 days and when lasts for \>3 months is referred to as chronic kidney disease (CKD). Acute kidney injury (AKI) is associated with poor outcome in critically ill children. The reported incidence rate of AKI in children admitted to pediatric intensive care units (PICUs) ranges from 8% and 89% worldwide. Stage 1 was identified in 24.24% of the AKI cases, stage 2 in 31.03% and stage 3 in 44.71%. The most prevalent cause of AKI was represented by prerenal AKI in 85.64% of the cases, followed by 12.16% renal causes respectively 2.18% postrenal causes. Symptoms of an AKI come on suddenly, over the course of hours or days. They depend on the underlying cause, but some of the most common symptoms include hematuria, fever, rash, bloody diarrhea, severe vomiting, abdominal pain, no urine output or high urine output, pale skin. oedema, puffy eyes and detectable abdominal mass. There are many predisposing factors that lead to AKI for such as gastroenteritis, presence of infection, sepsis, shock, cardiac disease, mechanical ventilation hypoxia and coagulopathy are important predictors for AKI. Despite significant developments in the management of AKI, the overall mortality rate of patients with AKI has not improved dramatically. The most widely available studies deal primarily with AKI, reporting mortality rates between 11% and 63% in pediatric patients. Outcomes among children who develop acute kidney injury (AKI). Children who develop AKI while hospitalized are at risk for poorer short- and mid/long-term outcomes. Across both acute and critical care populations, AKI is associated with longer lengths of stay, non-recovery of baseline renal function, and chronic renal disease including proteinuria, hypertension, and chronic kidney disease (CKD)
