OBSERVATIONAL STUDY ON ROLE OF NEUROSONOGRAM IN INTRACRANIAL PATHOLOGIES IN NEONATES AT A TERTIARY CARE CENTER.

Abstract

ABSTRACT BACKGROUND AND OBJECTIVES: Neonates face a lot of challenges especially based on their gestational age, maternal factors, birth weight at the time of delivery, immediate cry following birth. H ypoxic ischemic encephalopathy and Germinal matrix haemorrhage constitutes major portion of those challenges. To identify varied conditions, we can take help of imaging in form of neurosonogram. METHODS : Neurosonogram was carried out on all n tool including followeonates both as screening and diagnostic up scans. A total of 100 preterm babies with positive findings were included in the study. An analysis was performed over different pathologies including grading of specific condition in requir ed areas. RESULTS: Our study comprising of 100 neonates with brain pathologies showed following results. In our study of 100 neonates, most of the disease burden is by vascular causes (56%), then followed by infective (19%), congenit al (14%), trauma (8%), metabolic (2%) and miscellaneous (2%). 52% of PVL showed associated risk factors. CONCLUSION: In our study 100 preterm babies with suspected brain injuries were studied with ultrasound through anterior fontanelle and mastoid sutures. Neurosonogram can detect various intracranial pathologies on par with CT scan . Transcranial doppler can reflect the cerebral blood volume and perfusion status through RESISTIVE INDEX and abnormal values according to literature are >0.8 and <0.4 and can be noticed in severe HIE and conditions which increases intracranial pressure . Any measure that decreases the vasospasm which decreases RI can eventually prevent the neonate having progression of ischemia and further new infarct. 1
