H&O Equipments CryoPen M Gebrauchsanweisung Seite 17

The duration of the treatment will depend on the surface and the thickness of the tissue being
treated. Thickness must be estimated based on clinical experience. After the first freezing cycle
the tissue should be allowed to thaw for about 30 seconds followed by a second freeze.
Note that the tissue will freeze faster than during the first freezing cycle.
This 'freeze-thaw-freeze' technique offers the best opportunity for success.
You will find this procedure in most literature on cryotherapy.
A follow-up visit is recommended after 2 to 4 weeks to confirm that all pathological tissue
has disappeared and check if a follow-up treatment is necessary.
Interact with your patients
Inform patients that there will be a pain sensation similar to a ballpoint being pushed onto
the skin. Generally, little or no discomfort is experienced during the first few seconds when
you manage to avoid treatment of healthy tissue.
The ice will reach the caudal extent of the lesion after a given amount of time related
to the depth of the lesion. From that moment the patient will experience a pain sensation.
This may be the moment to stop treatment. You may eventually add a few seconds more
depending on the patient's comfort level and upon the clinical evaluation of the operation.
There might be a little residual stinging for a few minutes after treatment.
Occasionally, a blister might form and persist for a few hours.
