RESUMO
OBJECTIVE: To probe and systematize the ancient cauterization with pyropuncture needle for evacuation of pus. METHODS: One hundred and eight cases of body surface abscess were randomly divided into 2 groups. The cauterization group (n=84) were treated by drainage with electric cauterization and the incision group (n=24) by drainage with incision. Clinical therapeutic effect, the healing time and the scar area of the wound were compared between the two groups. RESULTS: All of the patients in the two groups were effective with a similar therapeutic effect (P > 0.05); the cauterization group in the healing time and the scar area of the wound was superior to the incision group (P < 0.05). CONCLUSION: Electric cauterization for evacuation of pus has advantages of rapid healing and small scar area of wound.
