The melting point of norflurane is –103.3°C.

How do you treat with Hydrozid?

Hydrozid is applied directly to a lesion from the canister. Hydrozid should be applied from a distance of 2 to 3 cm and for 2 to 6 seconds, depending upon the type and location of the lesion. Several repeated freeze-thaw cycles – up to 6

The total duration of applications to the lesion must be kept within the recommended maximum total (please see the labelling on the canister Instructions for Use).

Gentle pressure on the spray-head gives a fine, narrow jet. Greater pressure produces a more powerful spray.

To avoid damaging surrounding tissues use one of the application templates provided. Carefully select the hole in the template which matches the size of the lesion and adjust the spray jet by varying the pressure on using the spray head.

Why are repeated freeze-thaw cycles (6 short freeze-thaw cycles) recommended rather than one long exposure?

There are no published data regarding optimal treatment in cryotherapy of skin lesions. Studies of cryotherapy in other therapeutic areas, however, have shown that repeated freeze-thaw cycles increase the effect, as the extent of tissue necrosis increases1
