Treatment
In most instances, there will be a graduated darkening of the
treatment site followed by the natural loss of necrotic tissue.
The time expected to return to a full repigmentation will differ
and is often very dependent on skin color.
Anesthesia is rarely employed in cryosurgical treatments and
this is due, in part, to the anesthetic effect of the cold. Typically,
patients will experience little or no discomfort during treatment.
Subsequently, there could be a very light feeling of irritation at the
site. Longer contact application times could produce some patient
reaction.
Follow-Up
Depending on the patient and the treatment, qualitative results
may be only a few days (e.g., age pigmentation) or several months,
(e.g., plantar warts). It is recommended that patient follow-up be
considered if adequate time has elapsed. Unsatisfactory outcomes
may require additional treatment which could include longer
application time. Formation of a blister, if that should occur, must
be addressed as would any other wound in order to preclude
infection. Additionally, this area should be protected until a full
pigmentation is evidenced.
Cleaning/Sterilizing of Dispensing Tips
• Tips should be cleaned with an alcohol swab or disinfectant.
• Only use a lint-free cloth to clean, disinfect and wipe off
tips in order to avoid particles sticking to the inlet of the tip,
which may result in a blocked tip.
• Rinse tips with deionized, sterile, or demineralized water
immediately following disinfection in order to avoid particles
from drying and sticking to the inlet of tip, which may result
in a blocked tip.
• The glass dispensing tips should be steam sterilized if in
contact with blood, mucous or infected tissue.
• Do not subject the control mechanism to steam sterilization.
