Value of Bedside Ultrasound Measurement of Optic Nerve Sheath Diameter in Diagnosis of In-creased Intracranial Pressure in Central Nervous System Infection
Objective To analyze the value of optic nerve sheath diameter(ONSD)measured by bedside ul-trasound in the diagnosis of intracranial pressure(ICP)in patients with central nervous system infection.Meth-ods Retrospectively selected the clinical data of 96 patients with central nervous system infections admitted to the Affiliated Hospital of Xuzhou Medical University between March 2020 and March 2023.They were divided into the group with normal ICP(n=45)and the group with increased ICP(n=51)based on the lumbar puncture detection of cerebrospinal fluid pressure result.The difference in ONSD levels between the two groups was ana-lyzed,and the receiver operating characteristic curve(ROC)was plotted to calculate the diagnostic efficacy of ONSD in evaluating elevated ICP.Results The ONSD of increased ICP group was(5.61±0.51)mm,which was higher than that of normal ICP group(4.50±0.52)mm,and the difference was statistically significant(P<0.05).The diagnostic sensitivity,specificity,and area under the curve of ONSD for increased ICP were 90.2%,86.7%,and 0.932,respectively,with an optimal cutoff value of 5.01 mm.Conclusion ONSD can increase with the in-crease of ICP in patients with central nervous system infection.Real-time ultrasound measurement of ONSD can reflect the increase of ICP well.
