CRYOANALGESIA (CRYOABLATION OF NERVES)
Cryoanalgesia is a method of achieving temporary interruption of the transmission of pain through a particular nerve using freezing cold probe application over a period of time.

INDICATIONS: Multiple indications, including peripheral and axial spine related pain indications, exist for the use of cryoanalgesia. The patient usually has the site localized by a previous local anesthetic injection and confirmation that relief will occur with ablation of that nerve. Following that, the probe is inserted into the location and the freezing is done in cycles with the probe in close proximity to the nerve that is targeted. This could be an axial spine nerve, like a facet nerve, or it could be a peripheral nerve, like a neuromacyte, in the extremities. This is followed by the interruption of the transmission of pain signals in that particular location.

CONTRAINDICATIONS: Contraindications include anticoagulation, especially when the probe is used at a deep location within the human body or close to the axial spine and is relative. Contraindications are also present when the procedure is done using fluoroscopic guidance. A pregnant patient, or a patient who may suspect she may be pregnant, should not participate in that procedure because of the risks of x-ray radiation to the fetus.

COMPLICATIONS: Complications are extremely rare; however, the most common complication appears to be discoloration of the overlying skin, especially if the tip of the probe to skin distance is short. This could result in cosmetically unpleasant discoloration of the skin that is usually temporary and will resolve over time.

SEDATIVES: Sedatives are usually not indicated but may be given on request.
