| hypobaric | 1. <physics> Pertaining to pressure of ambient gases below 1 atmosphere. 2. <chemistry> With respect to solutions, less dense than the diluent or medium; e.g., in spinal anaesthesia, a hypobaric solution has a density lower than that of spinal fluid. Origin: hypo-+ G. Baros, weight (05 Mar 2000) |

| hypobaric spinal anaesthesia | <anaesthetics> Spinal anaesthesia in which spread of local anaesthetic solution in the subarachnoid space is controlled by adjusting the position of the patient when the density of the local anaesthetic solution is made less than the density of cerebrospinal fluid (i.e., hypobaric) by the addition of distilled water.

| hypobaric |
Pressure lower than normal atmospheric pressure. This is experienced at altitude.

| hypobaric s. |
a solution having a specific gravity less than that of a standard of reference, such as one used for spinal anesthesia having a specific gravity less than that of the spinal fluid, causing it to migrate upward and produce anesthesia above the level of injection.
