This spinal block pressure, the spinal equivalent to intracranial pressure, was measured by lumbar infusion of fluid and simultaneous recording of the volume-pressure curve caudal to the block. The point of deviation from or breakthrough of the exponential volume-pressure curve indicated the spinal block pressure. Spinal block pressure of about 500 mm H<jats:sub>2<\/jats:sub>O and more could be determined by this method, and, when it was combined with Queckenstedt's test, lower pressures could be assessed as well. In the static (thoracic) part of the spine, spinal block pressure up to the level of arterial blood pressure was recorded. In the dynamic part of the spine, however, spinal block pressure could exceed arterial blood pressure due to external compressive forces during extension of the spine.<\/jats:p>\n<jats:p content-type=\"fine-print\">There was a general tendency for more severe neurological deficits in patients with high spinal block pressure; but the duration of the pressure, additional focal pressure, and spinal cord compared with nerve root compression seemed equally important factors.<\/jats:p>\n<jats:p content-type=\"fine-print\">The recording has implications for diagnosis, positioning of patients for myelography and surgery, selection of high-risk patients for the most appropriate surgical procedure, and detection of postoperative hematoma. There were no complications associated with the recordings.<\/jats:p>","DOI":"10.3171\/jns.1982.57.1.0048","type":"journal-article","created":{"date-parts":[[2009,5,8]],"date-time":"2009-05-08T13:57:50Z","timestamp":1241791070000},"page":"48-56","source":"Crossref","is-referenced-by-count":12,"title":["Clinical recording of pressure on the spinal cord and cauda equina"],"prefix":"10.3171","volume":"57","author":[{"given":"Bj\u00f8rn","family":"Magnaes","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1","series-title":"Acta Neurol Scand","doi-asserted-by":"publisher","first-page":"487","DOI":"10.1111\/j.1600-0404.1965.tb04739.x","article-title":"CSF dynamic diagnosis of spinal block II: the spinal CSF pressure-volume curve.","volume":"41","author":"Gilland","year":"1965"},{"key":"b2","series-title":"Acta Neurol Scand","first-page":"47","article-title":"CSF dynamic diagnosis of spinal block III: an equation for block influence on cisterno-lumbar electromanometrics.","volume":"41","author":"Gilland","year":"1965"},{"key":"b3","series-title":"Acta Neurol Scand","first-page":"107","article-title":"Electromanometric recording of cerebrospinal fluid blocks in the cervical region.","volume":"41","author":"H\u00f6\u00f6k","year":"1965"},{"key":"b4","series-title":"Brain","doi-asserted-by":"publisher","first-page":"337","DOI":"10.1093\/brain\/73.3.337","article-title":"The effect of head posture on the manometrics of the cerebrospinal fluid in cervical lesions: a new diagnostic test.","volume":"73","author":"Kaplan","year":"1950"},{"key":"b5","series-title":"Queckenstedt's Test: Electromanometric Examination of CSF Pressure on Jugular Compression and Its Clinical Value.","author":"Lakke","year":"1969"},{"key":"b6","series-title":"Acta Neurol Scand","first-page":"575","article-title":"Cranial and spinal components of the cerebrospinal fluid pressure-volume curve.","volume":"49","author":"L\u00f6fgren","year":"1973"},{"key":"b7","series-title":"J Neurosurg","doi-asserted-by":"publisher","first-page":"57","DOI":"10.3171\/jns.1982.57.1.0057","article-title":"Clinical recording of pressure on the spinal cord and cauda equina.
