[Leeches in the intensive care unit: nursing care].

Leeches have been used in medicine since ancient times. Leeches or Hirudos were used to treat multiple diseases, since the bleeding they induce was related to purification. This practice subsequently fell into disuse until the 1980s when leeches again began to be applied in the treatment of venous congestion and in plastic and reconstructive surgery, especially in the USA and Germany.
