This case study describes the successful use of maggot therapy to debride a full thickness pressure ulcer on a 56 year-old male with a history of NIDDM, CAD, PVD, and neuropathy. The patient had a non-healing ulcer of the heel greater than six months. He had undergone an arterial bypass of the affected leg that restored the blood flow two months prior to the maggot therapy. The wound measured 6x9cm with unknown depth due to the nonviable tissue covering the wound, and was infected with MRSA. Numerous debridement methods were used, including conservative sharp, enzymatic, whirlpool, pulsed lavage and surgical. The patient was frustrated with the wound's failure to heal, the inability to return to his daily activities, and frequent visits to clinics. Upon his own research, he requested maggot debridement and the physician ordered the therapy. A vial of 250-500 sterile maggots was placed on the wound and dressed per protocol. The patient was instructed how to care for the wound at home. The following day the patient was called. He denied any discomfort and stated he felt a “pressure type feeling” only. On day two, the patient returned for the removal of the maggots. They were easily removed with saline and gauze and he again denied discomfort. The wound was >50% clean after the two day treatment. Unfortunately, the therapy was not repeated due to unrelated issues. However, the patient was satisfied with the results of the maggot therapy and was willing to do it again. The cost of the maggot therapy was much less than the other debridement modalities that had been used. The speed of debridement, the minimal cost, and the patient's positive experience are encouraging and warrant providers to consider this debridement option more often for necrotic wounds.
