should be held 0,5 to 3 mm from the
lesion. When further than 5 mm from
the applicator tip the liquefied N2O will
have expanded into gas phase which is
not effective for achieving therapeutic
results.
By approaching the lesion with the gas
flowing you will observe the focal point
of the jet on the tissue. The closer you will
approach the lesion, the more freezing
power you will apply to the tissue. It is
recommended to keep a greater distance
for the smaller
procedures.
The amount of liquid N2O that you wish
to apply can be controlled by moving
the applicator quickly towards and away
from the tissue. Circular
movements have the same effect.
Do not hold the Freezpen applicator still
over the lesion. It may flood the area and
damage healthy tissue surrounding the
lesion. This can cause blisters and pain to patients.
The condensation of the humidity in the air on the frozen working
area during the operation may create an ice field on top of the
lesion. This 'igloo' will hinder the effective working of the liquid
phase of the cryogen (at -89°C/-128°F) and should be removed
with the applicator tip by gently wiping the ice. Although, they are
relatively harmless protect the area from blown ice shards.
After the thawing, the tissue turns reddish and has the aspect of a
zone of inflammation due to interstitial bleeding. Some edema and/
or blister may occur and will discomfort for some hours.
Always protect this new grown skin by using a sunblocker for 8 to 20
days after the scab has come off.
The learning curve for utilizing the Freezpen is short. With the
application of the measures for good practice, the Freezpen
provides sufficient control on the parameters for achieving good
treatment results and avoid unintended damage to tissue. Start
