Analysis about diagnosis of intracranial hemorrhage in premature infants with different gestational ages and birth weights by bedside cranial ultrasound
Objective To analyze the diagnostic value of bedside cranial ultrasound in preterm infants with intracranial hemorrhage,and to explore the effect of different gestational ages and birth weight of preterm infants on the incidence of intracranial hemorrhage.Methods According to random number table method,96 cases of premature infants admitted in department of ultrasonic intervention of Puyang Traditional Chinese Medicine hospital from June 2021 to June 2022 were selected into this study.The main ultrasonic manifestations of intracranial hemorrhage in premature infants were analyzed,and the incidence of intracranial hemorrhage in premature infants with different gestational age and weight was observed by bedside brain ultrasound.Results 26 cases of intracranial hemorrhage were detected,and the incidence was 27.08％.There was intraventricular hemorrhage accounting for 88.46％.Cerebral parenchymal hemorrhage accounted for 7.69％,and subdural hemorrhage was 3.85％.There was no gender difference between male and female preterm infants(P＞0.05).The rate of intracranial hemorrhage in preterm infants with gestational age＜32 weeks was 39.13％,which was significantly higher than that in preterm infants with gestational age ≥32 weeks,16.00％(P＜0.05).The intracranial hemorrhage rate of preterm infants with birth weight＜1500g was 38.09％which was higher than that of preterm infants with birth weight≥ 1500g(18.52％,P＜0.05).Conclusion Premature infants with low gestational age and low body weight have a higher probability of intracranial hemorrhage.Bedside cranial ultrasound examination for intracranial hemorrhage in preterm infants is noninvasive and convenient,and it can obtain accurate and reliable information.It can be used as an important method to screen and monitor intracranial hemorrhage in preterm infants,which is worthy of clinical promotion.
