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. The use of leeches is not yet widespread in Spain. One of the Spanish hospitals pioneering this practice is the University Hospital Joan XXIII de Tarragona, where leeches are employed in the Maxillofacial Service among patients with microvascularized grafts. The present article describes the therapeutic use of leeches (Hirudo medicinalis), as well as the nursing care and complications in patients undergoing this treatment. The aim is to ensure that this new technique is used with maximal safety and quality.
