9 Biopharm also recommends cutting a hole in the center of a gauze pad, moistening the pad with water, and placing it over the treatment area. These techniques help focus the leeches on the treatment area, and prevent them from attaching to the surrounding healthy tissue. As leech bites bleed freely, without being covered by dressings, it is imperative that universal precautions be maintained. The most effective means of accomplishing this is to contain the bleeding in one area using leak-proof padding. Place pads around and under the treatment area and be prepared to change them frequently.
Nurses are usually responsible for the application of the leeches.
Here are some suggestions for becoming an accomplished leech handler. First, move the container of leeches close to the patient, so you are not walking across the room with each leech. Wearing nonsterile gloves, take a long pair of nontoothed forceps in one hand and carefully lift the lid of the container. Be prepared to see some leeches clinging to the sides and even the lid of the container. It will be easier at first to try to catch the leeches that are swimming.
