What is the recommended action if a newborn does not urinate within 48 hours?

The recommended action when a newborn does not urinate within 48 hours is to initiate a diagnostic evaluation and/or intervention. This response is crucial because the absence of urination can indicate potential issues with the infant's renal function or hydration status. In newborns, particularly, timely assessment is critical as it can point to underlying conditions such as congenital anomalies or inadequate fluid intake that may require prompt medical attention.

Monitoring urinary output is an essential part of neonatal care, as it helps to assess the infant's well-being and ensure that the kidneys are functioning properly. By taking action within the first days of life, healthcare providers can address any significant issues swiftly, minimizing potential complications in the newborn's health. Prompt investigation allows for the appropriate management of any identified problems, thus safeguarding the infant's health.
