title: 5-Hydroxyindoleacetic acid and homovanillic acid in human cerebrospinal fluid below partial and complete spinal subarachnoid block.
abstract: Concentrations of homovanillic acid (HVA) and 5-hydroxyindoleacetic acid (5-HIAA) were investigated by lumbar cerebrospinal fluid (CSF) of 21 patients with partial and total spinal subarachnoid block. HVA levels in CSF below a complete block were significantly lower and 5-HIAA levels were signigicantly higher than controls. Below a partial block, HVA levels were normal; 5-HIAA levels were higher than in patients with complete block. Possible explanations for these findings are discussed.
