Suction blister

The suction blister technique ( " Saugblasentechnik " ) is a technique for skin graft due to chronic skin damage such as poor healing leg ulcers and the white spot disease ( vitiligo ) can be treated. It is a technically simpler alternative to split-thickness or full-thickness skin grafts to.

By applying a suction or a modified syringe, the lamina lucida of the skin is detached from the underlying layers in order to separate the epidermis from under the skin. The applied negative pressure of 200-300 mmHg caused within two to three hours bubbles. The roof of the bubbles is then cut sterile and transferred to the target region. Since only the epidermis is peeled off, the wounds do not bleed (so-called erosions ) and heal without scarring later on. The technique can be performed under local anesthesia.

The Suction - blister technique is also used in pharmacological research to measure drug concentrations in the skin can. For this purpose they had been developed in 1967 by the Finnish dermatologists Urpo Kiistala.
