Study Notes
Intraventricular hemorrhages (IVH) are a common complication among premature infants, occurring mostly within the first few days of life. One of the critical aspects of managing IVH is monitoring the vital signs of affected infants. Here, we discuss various approaches to monitoring vital signs in newborns diagnosed with IVH.
Bedside Cranial Ultrasonography
Bedside cranial ultrasonography is the primary diagnostic tool for detecting IVH in newborns, providing essential information regarding the severity of the hemorrhage and the presence of posthemorrhagic hydrocephalus (PHH). Serial ultrasonography is recommended to track the progression of the hemorrhage and the development of PHH weekly until resolution or stabilization.
Frontal-Occipital Head Circumference Measurements
Serial daily measurements of frontal-occipital head circumference should be performed in infants with ultrasonographic evidence of PHH to assess the progression of the condition. This measurement serves as an adjunct tool to monitor the development of PHH and can guide interventions accordingly.
Laboratory Studies
Abnormalities in lymphocyte counts have been observed in infants with grades III and IV IVH and periventricular hemorrhagic infarction (PVHI), and while not diagnostic, these findings may lead to further evaluations.
Imaging Studies
While magnetic resonance imaging (MRI) is useful in determining the need and optimal intervention for posthemorrhagic hydrocephalus, cranial ultrasonography remains the primary tool for monitoring the changes in an IVH patient's status. Computed tomography (CT) scans are no longer used for diagnosis and follow-up due to the safety and cost-effectiveness of ultrasonography.
Cerebral Oxygenation Monitoring
Monitoring cerebral oxygenation is considered a promising approach to detect IVH and periventricular leukomalacia (PVL) through cerebral oximetry. By observing changes in cerebral blood flow, this technique may provide valuable insights into the progression of neurological complications in premature infants.
Conclusion
Monitoring vital signs in newborns with IVH requires a multifaceted approach involving regular cranial ultrasonography, serial head circumference measurements, laboratory investigations, and possibly cerebral oxygenation monitoring. These strategies allow healthcare practitioners to evaluate the severity and progression of IVH and PHH, prompt timely intervention, and ultimately improve outcomes in affected infants.
