Analgesia Units, Cryogenic
Definition : Analgesia units that alleviate pain by freezing body tissues. These units consist of a cryostat and a cooling probe; most units also include a peripheral nerve block stimulator (nerve locator). A compressed gas (e.g., carbon dioxide, nitrous dioxide) is circulated through the probe, allowing expansion near the tip; frequently, some free-thaw cycles are performed. Cryogenic analgesia application results in reversible, though prolonged (weeks or even months) peripheral nerve block; it is used for postoperative and chronic intractable pain relief.
