P. REMOVAL OF THE LEECHES
REMOVAL OF THE LEECHES
Touching the apical part of the leech with the tip of a gauze soaked in 70% alcohol, concentrated saline, vinegar, or lidocaine, would cause the leech to stop feeding and drop off.
When pulled off by force during blood feeding their jaws could remain on the skin and cause complications such as secondary infections.
Medicinal leeches should be used only once for curative purposes and in order to prevent any cross-infections.
Used leeches are killed in 70% ethyl alcohol or be frozen at a temperature of −18oC for at least 12 hrs. and thereafter they are disposed in bags for biological waste.
