Quick takeaways

  • Monitoring urine output is crucial in the ICU as it acts as the 'fifth vital sign' and helps detect subtle manifestations of acute kidney injury.
  • Acute kidney injury can be classified into pre-renal, intrinsic renal, and post-renal causes, with pre-renal causes commonly observed in the ICU due to impaired kidney perfusion from conditions like shock.

Acute Kidney Injury: Prevalence and Impact

Acute kidney injury (AKI) is a significant problem, affecting up to 30% of patients admitted to the PICU and even higher rates in specific populations like those who have undergone cardiac bypass. AKI is associated with longer lengths of stay, increased need for ICU resources, and higher rates of morbidity and mortality. Despite its importance, AKI often goes unnoticed as it manifests subtly. Therefore, it is crucial for healthcare providers to actively monitor urine output, which acts as the 'fifth vital sign,' and to follow it closely throughout a patient's shift in the ICU.
