Introduction: HIE is often clinically suspected in the setting of a known perinatal stress event arising from a complicated or difcult delivery. The most sensitive and specic imaging technique for examining infants with suspected hypoxicischemic brain injury is MR imaging. It also gives information about the timing and specic patterns of injury and also suggest diagnoses other than HIE such as metabolic disorders and developmental disorders of the brain. MRI is also a useful tool in the determination of prognosis and also follow-up of HIE. Aim: This study was undertaken to evaluate the various MRI appearances of hypoxic ischemic encephalopathy in term and preterm neonates and to correlate the MRI appearances with clinical outcome. Materials and Methods: All neonates with history of birth asphyxia, referred for MRI examination to the Department of Radio-Diagnosis, K. R. Hospital attached to Mysore Medical College and Research Institute, during January 2018 to January 2019. All MRI scans were performed on GE optima MR360 1.5 Tesla. Sequences used were T1W axial, T1 FLAIR axial, T2W axial, T2 FLAIR axial, T1W sag, T2W coronal, T2W GRE axial, DWI axial and ADC maps. Results: 30 babies with clinically suspicion of HIE and positive ndings on MR imaging were evaluated in our study. Out of 30 babies, 18 were term and 12 babies were preterm. Periventricular luecomalacia is most common MRI pattern in preterm and central pattern in term neonates. 16 babies had abnormal developmental outcome at 6 months follow up study. 16 babies with diffusion restriction in corpus callosum, 12 had abnormal outcome. 7 out of 10 babies with loss of normal signal in internal capsule had abnormal outcome. Babies with diffusion restriction in basal ganglia had gross developmental delay. Conclusion: MRI is the modality of choice for evaluation of HIE because of excellent gray – white matter resolution, well-depiction of myelination pattern and multi-planar imaging capabilities. There is a strong relation between the MRI appearances of birth asphyxia and the clinical outcome. Therefore MRI has a strong role in prognosticating lesions.

Objective To determine the short-term outcomes (abnormal brain magnetic resonance imaging [MRI]/death) in infants born with a 10-minute Apgar score of 0 who received therapeutic hypothermia and compare them with infants with higher scores. Study Design This is a retrospective review of 293 neonates (gestational age ≥ 35 weeks) born between November 2006 and October 2015 admitted with hypoxic-ischemic encephalopathy who received therapeutic hypothermia. Results of brain MRIs were assessed by the basal ganglia/watershed scoring system. Short-term outcomes were compared between infants with Apgar scores of 0, 1 to 4, and ≥5 at 10 minutes. Results Eight of 17 infants (47%) with an Apgar of 0 at 10 minutes survived, having 4 (24%) without abnormalities on the brain MRI and 7 (41%) without severe abnormalities. There was no significant difference in the combined outcomes of “death/abnormal MRI” and “death/severe abnormalities on the MRI” between infants with Apgar scores of 0 and 1 to 4. Follow-up data were available for six of eight surviving infants, and none had moderate or severe neurodevelopmental impairment. Conclusion In the cooling era, 47% of infants with no audible heart rate at 10 minutes and who were admitted to the neonatal intensive care unit survived; 24% without abnormalities on the brain MRI and 41% without severe abnormalities.

Background: Birth asphyxia is an important cause of static development and neurological handicap in both term and preterm infants. Birth asphyxia is found to be responsible for 28.7% deaths in hospital settings and 20% deaths in rural/tribal areas. Approximately the same number develops serious sequelae which cripples these children both physically and mentally. Children who have suffered moderate encephalopathy had varying rates of infant death and morbidity. Precise determination of the prognosis in the term new born, who sustains a hypoxic ischemic insult is hindered by difficulty in determining the severity of insult.Methods: This was a prospective longitudinal, observational study was conducted in the Department of Paediatrics, CMC Bhilai with close association with the Department of Obstetrics and Gynecology, Department of Radio diagnosis and Department of Neurology. All deliveries taking place in the Department of Obstetrics and Gynecology of CMC Bhilai were enrolled for the study. Each enrolled infant underwent a detailed neurologic examination within the first 12 hours after birth. During the period of data collection 180 babies with birth asphyxia were admitted to NICU. Out of which 126 babies had fulfilled the inclusion criteria and completed one year follow up, hence as cases. Babies who lost follow up were not included in study. The neurological examination was performed 14 days after discharge, then at 1 month, 3-month, 6-month, 9 month and 12 months. Long term outcome in this study is defined as outcome at one year of age in terms of morbidity and mortality.Results: The female and male ratio is 0.4:1. Most of the asphyxiated newborn, 81 (64%) were in 2500-3000gm. Among the study population, maximum number of cases 76 (60%) were suffering from HIE-I. Majority of study population, 87 (69%) were born by LSCS. Normal CUS in 93 babies and abnormal in 33 babies; with normal CUS, there were no death in study population and out of 33 abnormal CUS, 12 deaths occurred. Out of the different complications enlisted in the table convulsions (66.7%) is most common followed by Apnea (65.08%). Recurrent infections (45.24%) is the most common complication followed by seizure disorders (22.63%) and failure to thrive (20.63%).Conclusions: Hypoxic ischemic encephalopathy is one of the major consequences of perinatal asphyxia. Despite of best care, some babies are likely to develop it.

Objective: To quantify the prognostic value of neonatal brain magnetic resonance imaging (MRI) in neonatal hypoxic-ischemic encephalopathy. Methods: Meta-analysis of studies with ≥35-week neonates with hypoxic-ischemic encephalopathy who underwent brain MRI within age 4 weeks and had neurodevelopmental follow-up for at least 12 months. Results: An abnormal neonatal brain MRI was more frequent among patients with unfavorable neurodevelopmental outcome: odds ratio = 18.2 (95% confidence interval: 9.4-34.9), P <.0001. The prognostic value of neonatal brain MRI in moderate hypoxic-ischemic encephalopathy had an odds ratio of 17.7 (95% confidence interval: 5.3-59.3) and in severe hypoxic-ischemic encephalopathy, the odds ratio was 125.0 (95% confidence interval: 2.0-7917.1). Therapeutic hypothermia did not change the prognostic value of neonatal brain MRI (odds ratio for hypothermia, 14.0 [95% confidence interval: 3.1-63.6], vs no hypothermia, 18.1 [95% confidence interval: 10.0-33.1], P = .7525). Conclusion: Neonatal brain MRI provides prognostic information on outcome beyond early infancy in hypoxic-ischemic encephalopathy and therapeutic hypothermia does not change its prognostic value.

Introduction: Each year approximately 4 million babies are born asphyxiated, which results in 1 million deaths and an equal number of serious neurological sequelae. One of the commonest organs involved in birth asphyxia is brain which may lead to a syndrome of clinical manifestation called Hypoxic Ischemic Encephalopathy (HIE). Aims: To find out possible maternal and neonatal risk factors for Hypoxic Ischemic Encephalopathy, to analyze clinical presentations and outcome of HIE in asphyxiated newborns. Methods: Hospital based observational study was carried out among fifty newborns with Apgar score less than 7 at 1 minute of life admitted in Nepalgunj Medical College Teaching Hospital, Kohalpur, Banke. Results: The incidence of birth asphyxia and birth asphyxia with HIE were 37.2 per 1000 live births and 14 per 1000 live births with male: female ratio of 1.27:1. Most of the neonates 22(44%) were in HIE stage II. Meconium stained amniotic fluid 18 (36%) was the most common intrapartum risk factor followed by maternal use of intrapartum medications 14 (28%), Premature Rupture of Membrane (PROM) 8 (16%), prolonged labor 5 (10%) and obstructed labor 6 (12%). Four (8%) asphyxiated neonates with HIE had cord prolapse and 7 (14%) had cord around the neck. The most common resuscitation done was bag and mask ventilation (56%) (P<0.05). Majority of the studied neonates were of normal birth weight (76%) and head circumference (84%) (P<0.05) with clinical presentations of respiratory distress (88%), seizures (44%), apnea (22%), bradycardia (8%), tachycardia (6%) and bulged anterior fontanel (6%). The overall mortality of neonates with HIE was 20% of which most were of HIE stage III. Conclusion: Certain measures could be taken to prevent birth asphyxia: early detection and intervention of high risk pregnancy, prompt and effective resuscitation of asphyxiates newborns.

Early neurological assessment in infants with hypoxic ischemic encephalopathy (HIE) treated with hypothermia has not been systematically explored. The aims of the present study were to assess whether the Hammersmith Infant Neurological Examination (HINE) is a good tool to predict later neurodevelopmental outcomes at 2 year from birth in this population of infants. A total of 41 term born infants with HIE treated with hypothermia performed the HINE at 12 months and a neurodevelopmental assessment at 24 months. All the infants who had a global HINE score between 67 and 78 were able to walk independently at 2 years and reported a normal developmental quotient; language disorders were observed in a limited number of infants. HINE scores <67 were always associated with motor impairment. In conclusion, the HINE confirms its role as one of the early neurological examination tools for the diagnosis of high risk infants, even in infants with HIE treated with hypothermia. These results can be useful for clinicians involved in the follow up of these infants for early identification of motor disabilities and in planning appropriate intervention.

Despite major advances in monitoring technology and knowledge of fetal and neonatal pathophysiology, neonatal hypoxic-ischemic encephalopathy (HIE) remains one of the main causes of severe adverse neurological outcome in children. Until recently, there were no therapies other than supportive measures. Over the past several years, mild hypothermia has been proven to be safe to treat HIE. Unfortunately, this neuroprotective strategy seems efficient in preventing brain injury in some asphyxiated newborns, but not in all of them. Thus, there is increasing interest to rapidly understand how to refine hypothermia therapy and add neuroprotective or neurorestorative strategies. Several promising newer treatments to treat birth asphyxia and prevent its devastating neurological consequences are currently being tested. In this paper, the physiopathology behind HIE, the currently available treatment, the potential alternatives, and the next steps before implementation of these other treatments are reviewed.
