Leeches drilling into the human body according to the specific conditions of the patient, the following different treatment methods can be used: First, if the leeches drilling into the body of a small part, then you can tap the affected limbs, prompting the leeches to vibrate to come out by themselves. The wound needs to be squeezed out as soon as possible, and the vital iodine disinfection should be strengthened so as not to cause the local infection to aggravate progressively. Second, if the leech drilled into the human body part is more, simply through the local patting, can not play a better therapeutic effect. You can apply concentrated sodium chloride, high sugar, vinegar and white wine to promote the dehydration of leeches, so that the ability of leeches to adsorb the mucous membranes and blood vessels of the human body is significantly weakened, and the leeches can be dislodged on their own. If necessary, tetanus immunoglobulin injection is needed to prevent tetanus infection, and the wound needs to be actively disinfected.
