However, previous attempts have not shown conclusive results. In this work, glycorrhachia is demonstrated to be an adequate predictive parameter after spinal anesthesia using 0.5% hyperbaric bupivacaine.<\/jats:p>\n               <jats:p>\n                  <jats:bold>Methods:<\/jats:bold> Two mL of local anesthetic through a continuous spinal catheter was administered to 40 patients. CSF was sampled at different time intervals from the onset of infusion to motor recovery. CSF bupivacaine concentrations were measured using chromatography. An automated analyzer was used for determining glycorrhachia in the same samples.<\/jats:p>\n               <jats:p>\n                  <jats:bold>Results:<\/jats:bold> For all patients, good correlation (r<jats:sup>2<\/jats:sup>&gt;0.95, p&lt;0.05) was obtained. From these results, it was possible to develop a general model which establishes the relationship between CSF glucose and bupivacaine concentrations (R<jats:sup>2<\/jats:sup>=0.987, p&lt;0.05). Motor block is reached when CSF glucose concentration is about 245\u00a0mg\/dL (13.5\u00a0mmol\/L), which corresponds to 35\u00a0\u03bcg\/mL of bupivacaine.<\/jats:p>\n               <jats:p>\n                  <jats:bold>Conclusions:<\/jats:bold> Glycorrhachia measured during surgical intervention in patients undergoing spinal anesthesia with hyperbaric bupivacaine provides a mechanism for predicting the duration of motor block in a rapid and simple manner.<\/jats:p>\n               <jats:p>Clin Chem Lab Med
