Application of ultrasound multi-probe scanning in the diagnosis of neonatal craniocerebral diseases

Abstract

Objective To study the accuracy and sensitivity of ultrasound low frequency probe between low frequency probe combined with high frequency probe in the diagnosis of neonatal craniocerebral diseases. Methods Ninety newborns with high risk factors of craniocerebral diseases (premature delivery, low body weight, multiple pregnancies, hypoxic asphyxia and intrapartum infection) admitted to Heyuan Maternal and Child Health Hospital from January 2017 to December 2018 were selected as the study subjects. All newborns were divided into two groups by random number table method. The study group (45 cases) was given a low-frequency probe combined with a high-frequency probe for exploration, and the control group (45 cases) was only given a low-frequency probe for exploration. Combined with gold standard CT examination and clinical treatment, the accuracy and sensitivity of the two groups of detection methods were compared. Results The diagnostic accuracy of the study group for the detection of neonatal hypoxic ischemic encephalopathy, intraventricular hemorrhage and subependymal hemorrhage were 87.5%, 100%, 100%, respectively, higher than the corresponding control group (15.38%, 12.5%, 0%), the difference was statistically significant (P 0.05). The efficiency of the study group for detecting neonatal brain disease was 82.22%, which was higher than that of the control group (22.22%), and the difference was statistically significant (P<0.05). Conclusion Ultrasonic low frequency probe combined with high frequency probe could improve the accuracy of diagnosis of neonatal craniocerebral diseases such as hypoxic ischemic encephalopathy, intraventricular hemorrhage and subependymal hemorrhage, and diagnoses neonatal brain parenchymal hemorrhage and hydrocephalus. There is no difference in the accuracy rate, and it is sensitive to the diagnosis of craniocerebral diseases, so it has important clinical value.
