Exploring the Value of Bedside Craniocerebral Ultrasound in the Dynamic Observation of Neonatal Subependymal Hemorrhage

Background: The purpose of this study is to investigate the ultrasonic performance of bedside brain ultrasound in the observation of subependymal hemorrhages (SEH) in newborns and provide evidence for clinical prevention and treatment of hemorrhage. 152 cases of newborns diagnosed as SEH were examined and followed up regularly, and their ultrasonographic features were analyzed. As a result, the craniocerebral ultrasound found strong and slightly strong echo in the anterior horn of the lateral ventricle and the thalamic caudate nucleus region, which did not affect the lateral ventricle. In the early stage of hemorrhage, the lesions showed a high echo and the border was slightly blurred. The echo gradually increased and the boundaries became clear at the stable period. During the absorption period, the center of the lesion was low echogenic and the edge was still hyper echoic, and gradually formed a poorly sound, separated thick cyst cavity. Subsequently, there was no echo area in the center of the lesion, and eventually the lumen was formed under the subependymal hemorrhage. Post discharge follow-up showed that 6 cases (3.95% 6/152), 75 cases (49.34% 75/152), 37 cases (24.34% 37/152), 13 cases (8.55% 13/152) had their cyst cavity disappeared after their hemorrhage in 1 months and 2 months, 3 months and 6 months. The patients with their lesions basically absorbed within 6 months accounted for 86.18% (131/152). Conclusion: Intracranial ultrasound has the advantage of early diagnosis of SEH, and it can be used to observe the patient's bedside examination, to observe the change of the course of the disease dynamically, to evaluate the blood transfer, to effectively guide the clinical medication and evaluate the prognosis
