"What Are the Harms of Leeches to Human Bodies?"
Main Harm of Leeches to the Human Body
The primary hazard posed by leeches to human bodies lies in their blood-sucking nature. Consequently, prolonged presence of leeches within the body can lead to severe anemia, manifesting as paleness. Furthermore, neglecting to promptly treat a leech bite can result in wound infection and potentially tetanus. Therefore, upon discovering a leech in the body, it is imperative to promptly seek medical attention for its removal and subsequent disinfection.
Treatment Methods
-
Tapping
Due to the suction cups surrounding the leech's mouth, it firmly adheres to the skin and mucosa, offering a strong attachment. Forcibly pulling the leech out may cause it to break and remain in the body, leading to severe infection. Instead, gently tapping the muscles and skin surrounding the leech can loosen its suction cups, allowing some leeches to detach themselves.
-
Wet Dressing
If a leech has fully entered the body, applying a solution of high-sugar, hypertonic saline, or vinegar to the entry point can induce excessive water excretion, leading to dehydration and loosening of the leech's suction cups, facilitating its spontaneous detachment. The wound must then be alternately rinsed with iodophor and physiological saline, with frequent dressing changes. Additionally, tetanus antitoxin should be administered to prevent tetanus infection.
-
Disinfection
If the leech's three-petaled triangular Y-shaped mouthparts remain embedded in the skin, causing persistent itching, the solution involves scraping the wound with a sharp blade followed by disinfection. If itching persists the following day, continued scraping and disinfection are necessary to prevent post-healing itching. This process should be carried out under the guidance of a qualified medical professional.
