Negative Cultures for Cerebrospinal Fluid Samples taken from the Myelomeningocele Sac on the Day of Repair.

Objective: Our goal was to evaluate the intraoperative laboratory analysis of cerebrospinal fluid (CSF) aspirated from the myelomeningocele (MMC) sac prior to the repair to determine if there was bacterial growth in the culture.

Methods: This was a retrospective analysis of the CSF cultures of 45 MMC patients operated on during the years of 2002 to 2013 at the University Pediatric Hospital. Before repairing the defect, the sac area was cleaned and three milliliters of CSF were drawn and sent for analysis for red blood cells, white blood cells, glucose level, protein level, chloride level, gram stain and culture.
