Baricity

The Barizität is a clinically relevant quantity of a local anesthetic. It describes the ratio of the densities of local anesthetic and cerebrospinal fluid at 37 ° C. The indication of Barizität complements the indication of the temperature-dependent density of the gravity -dependent or specific gravity. While a substance of the same density ( isobaric ) remaining after intrathecal injection in the region of the injection location for the implementation of a spinal decreases a substance having a higher density ( hyperbaric ) from which is used to control the action of propagation.
