Patient-controlled epidural analgesia during labor: a comparison of three solutions with a continuous infusion control.

abstract：BACKGROUND:Cerebrospinal fluid (CSF) outflow to intra- and extracranial subarachnoid spaces caused by arterial inflow to the brain predominantly compensates systolic increases in cerebral blood volume. Phase-contrast magnetic resonance imaging is a new tool for noninvasive assessment of CSF displacement by measuring CS...
