Cerebrospinal Fluid Composition of Infants with Ischemic Stroke.

Objective: To characterize the cerebrospinal fluid (CSF) of infants with stroke and compare those findings to the CSF of infants with bacterial meningitis and neither condition in the first 14 postnatal days.

Study Design: Cohort study of 30,092 infants who received a lumbar puncture in the first 14 postnatal days discharged from >300 neonatal intensive care units from 1997-2020. CSF parameters were compared between infants with stroke and bacterial meningitis using non-parametric hypothesis testing and quantile regression.
