practicing on the regular lesions and treat the more delicate ones
after having acquired more experience.
Duration/Depth of the treatment.
Hold the tip of the applicator as close as possible to the lesion. In all
literature, the rapid drop of temperature (thermal shock) is described
as a critical criterion. However always relate to the part of the body
where the operation is applied. In some parts, skin is thinner which
requires more caution. A typical freeze on viral infections may last
from 5 to 10 seconds for a small flat wart, and up to 45 seconds
for a full thickness plantar wart. For general purposes most lesions
take about 2 to 30 seconds. The duration of the treatment time
will depend on the surface area and the thickness of the tissue.
Thickness must be estimated by the operator on clinical experience.
After the first freezing cycle, the tissue should be allowed to thaw
for about 30 seconds followed by a second freezing. Please note
that in the second cycle the tissue will freeze faster. 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 3 weeks to confirm that all the
pathological tissue has disappeared or that a follow-up treatment
is necessary.
Interact with your patients.
Inform patients that there may 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 the treatment of
healthy tissue is avoided. The freezing 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 more seconds depending on the patient's
comfort level and upon the clinical evaluation of the operator. There
might be a little residual stinging for some time after the treatment.
Occasionally, a blister might form and persist for a few hours.
