Early Retinal Findings Following Cooling in Neonatal Encephalopathy.

Background And Aim: Perinatal HI (hypoxia-ischemia)-related visual defects including blindness are known to be associated with ischemic lesions in intracerebral visual pathways and ischemic retinal damage (IRD). Intraocular hemorrhages (IOH) such as retinal hemorrhage (RH), which may result from perinatal HI, can cause IRD by various mechanisms. We aimed to evaluate the early retinal findings in neonates with moderate-to-severe neonatal encephalopathy (NE) who underwent TH and its relationship between coagulation status, amplitude-integrated electroencephalography (aEEG) patterns, and magnetic resonance imaging-magnetic resonance spectroscopy (MRI-MRS) findings.

Therapeutic hypothermia for neonatal encephalopathy implications for neonatal units in India.

Therapeutic hypothermia has recently emerged from bench to bedside. Three large multicenter trials from industrialized countries and three independent meta-analyses have shown its efficacy in reducing death and disability following neonatal encephalopathy due a perinatal hypoxic event. Many neonatal units in well-resourced settings now offer hypothermia as standard care in neonatal encephalopathy.

Artifacts on electroencephalograms may influence the amplitude-integrated EEG classification: a qualitative analysis in neonatal encephalopathy.

This is a case report and a descriptive study demonstrating that artifacts are common during long-term recording of amplitude-integrated electroencephalograms and may lead to erroneous classification of the amplitude-integrated electroencephalogram trace. Artifacts occurred in 12% of 200 hours of recording time sampled from a representative sample of 20 infants with neonatal encephalopathy. Artifacts derived from electrical or movement interference occurred with similar frequency; both types of artifacts influenced the voltage and width of the amplitude-integrated electroencephalogram band.
