Official Title: Crystallization of Local Anesthetic and Adjuvant Mixtures in Cerebrospinal Fluid as a Model for Interstitial Space - a Semiquantitative in Vitro Trial
Brief Summary:
Different mixtures of local anesthetics or local anesthetics with adjuvants that are known to precipitate in vitro are tested in human cerebrospinal fluid (CSF). CSF is gained from patients with normal pressure hydrocephalus scheduled for elective lumbar puncture. Patients signed an ICF for leftover samples.CSF will be assessed for pH values at different timepoints (t0-t3; 0 to 60 minutes).In a second step six commonly used mixtures of LA with LA or LAs with adjuvants will be mixed using the following mixture…
