Web1 de dez. de 2014 · Raised intracranial pressure (ICP) is common in cryptococcosis. Prior studies suggest elevated ICP is associated with mortality, and guidelines recommend frequent lumbar punctures (LPs) to control ICP. However, the magnitude of the impact of LPs on cryptococcal-related mortality is unknown. Methods: Webopening pressure: the amount of pressure measured in a manometer after insertion of a spinal needle into the subarachnoid space.
WebPatients: Patients (≥18 yr of age) who had a recorded OP on LP and high-resolution computed tomography imaging of the head. Patient age, sex, body mass index were calculated. Intracranial hypertension (IH) was defined with an OP≥25 cm-H2O and low intracranial pressure with an OP<15 cm-H2O.
The normal range for CSF is reported differently in various sources, with most reporting a normal range of 7-18 cmH2O in adults,1 though some consider the normal range 5-25 cmH2O.2 However, a pressure >25 cmH2O or <5 cmH2O should certainly prompt you to look for a source.
