The feasibility of Telemedicine in Implementation of Therapeutic Hypothermia for Management of Neonatal Hypoxic-Ischemic Encephalopathy in Resource-Limited Areas.

Background: Telemedicine is widely used in neonatal services in developed countries. Lack of expertise and/or facilities, however, limited its use in developing countries and around areas of military conflicts. To our knowledge, no reports are demonstrating the feasibility of administering therapeutic hypothermia (TH) through telemedicine to neonates with hypoxic-ischemic encephalopathy (HIE) in resource-limited areas.Methodology: This is a retrospective study, evaluating 22 patients who received TH, guided by telemedicine, through a mobile app (Telegram®). We assessed the feasibility of utilizing Telemedicine in guiding the application of TH to infants affected with HIE in the North-West of Syria between July 2020 and July 2021.Results: Out of 5,545 newborn infants delivered during the study period, 22 patients were eligible for TH guided by Telemedicine. Patients were referred for consultation at a median (IQR) of 137 (35-165) minutes of life. A median (IQR) of 12 (3-18) minutes elapsed between the call for a consultation and the consultant response, and a median (IQR) of 30 (0-42) minutes elapsed between seeking the consultation and the initiation of cooling therapy. Eighteen patients completed cooling for 72 hours. The patients' temperatures were within the target range (33-34°C) most of the time (84.1%).Conclusion: Telemedicine is a feasible method to guide the implementation TH for HIE in resource-limited areas. The short-term success rate is relatively high; however, further studies with a larger population are needed to confirm these findings.

Magnetic Resonance Imaging Evaluation of Perinatal Hypoxic Ischemic Encephalopathy: An Institutional Experience

Background Hypoxic–ischemic encephalopathy (HIE) is the most commonly diagnosed neurological abnormality affecting children leading to severe neurological deficits and a cause of neonatal mortality. HIE constitutes a diagnostic challenge in the prematurely born and full-term neonates. HIE causes severe neurological deficit in children and many a times goes unnoticed in early stages. The various patterns of central nervous system (CNS) involvement in HIE are dependent on factors, such as severity and duration of hypoxia, and brain maturity in preterm and full-term patients. Magnetic resonance imaging (MRI) has prognostic significance in detecting patterns of HIE secondary to mild-to-moderate and severe hypoxias and the imaging findings are highly dependent on the time at which imaging is done. MRI helps determine the prognosis of brain development in patients with HIE. Objective This retrospective study elucidates the spectrum of MRI findings in preterm and full-term patients with HIE on MRI. Materials and Methods This retrospective descriptive study was conducted at a tertiary care center between April 2017 and May 2019 on 50 patients with a clinical diagnosis of HIE using a General Electric (GE) 1.5-Tesla MRI scanner. Various patterns of HIE were evaluated on MRI in preterm and full-term patients. Results This retrospective study evaluated MRI findings in 50 infants diagnosed with HIE. Eighteen (36%) were preterm and 32 (64%) were full-term patients. Thirty-five (70%) were male and 15 (30%) were female patients. In the current study, developmental delay was the most commonly associated clinical entity in both preterm and full-term patients. In preterm patients, periventricular leukomalacia was the most prevalent MRI finding, and in full-term patients, subcortical and periventricular white matter hyperintensities on T2-weighted and fluid-attenuated inversion recovery (FLAIR) sequences were most commonly encountered. Conclusion MRI is the primary imaging modality of choice in preterm and full-term patients with HIE, as it helps determine the severity of hypoxic–ischemic injury by understanding the pattern of brain involvement. In the current study, distinguishable patterns of MRI findings secondary to birth asphyxia and ischemic insult were elucidated in both preterm and full-term patients who are highly dependent on the level of brain maturity at the time of imaging. Regular MRI follow-up has a prognostic significance in HIE with accurate prediction of neurodevelopmental outcome on follow-up studies.
