Abstract:
Objective:To summarize the treatment experience of diabetes mellitus combined with necrotizing fasciitis.Methods:A retrospective analysis was conducted on the clinical data of patients diagnosed with diabetes mellitus and necrotizing fasciitis who were admitted to the Department of Burns and Plastic Surgery, Affiliated Hospital of Guizhou Medical University between September 2018 and December 2020. Upon admission, initial treatment involved blood glucose management, the administration of empirical antibiotics to combat infection, and concurrent nutritional support therapy. Surgical interventions, including either dilatation or incision and drainage, were promptly performed within 24 to 72 hours. During these procedures, necrotic tissues and purulent exudates were collected for pathogen culture and antibiotic sensitivity testing to guide appropriate treatment. Post-operatively, a negative pressure closed drainage system was installed to facilitate wound drainage, combined with 1.5% hydrogen peroxide solution to flush the wound or subcutaneous placement of multiple drainage tubes to drain the wound. If post-surgical infection persisted, additional dilatations were deemed necessary. Under the condition of clean wound and fresh granulation tissue, the wound was repaired by medium-thickness skin grafting on the lateral thigh. The laboratory risk indicator for necrotizing fasciitis (LRINEC) was checked and scored, including C-reactive protein, white blood cell count, hemoglobin, blood sodium, blood creatinine, and blood glucose levels. The total score was 0-13 points. When the score was ≥ 6 points, necrotizing fasciitis should be actively suspected. Observation of trauma infection control, statistics on the number of dilatations, trauma repair modalities, hospitalization time, and amputations, and follow-up of trauma healing and recurrence of necrotizing fasciitis were recorded.Results:A total of nine patients were enrolled, consisting of seven males and two females, with an age range of 39 to 81 years. The study population comprised patients with diabetes mellitus, with durations ranging from 0.5 to 10 years. The affected body parts included one upper extremity, six lower extremities, one perineum, and one case involving both a perineum and a lower extremity. LRINEC score ≥ 8 points in 5 cases and 6-7 points in 4 cases. The wound infection was controlled after 1 time dilatations in 4 cases, 2 times in 3 cases and 3 times in 2 cases, the infection of the trauma was controlled and reached a clean and fresh state of granulation tissue.In 7 cases, the trauma was healed after repairing with thick-medium-thick dermal grafting; in 1 case, the trauma was repaired by thin-medium-thick dermal grafting with scattered punctate recurring oozing, which was healed after changing the medication; and in 1 case, the right middle calf leg was amputated. Microbiological culture result: 2 cases of Staphylococcus aureus treated with intravenous drip of ceftazidime 2 000 mg once a day; 1 case of Pseudomonas pseudomallei was treated with intravenous drip of fluconazole 400 mg once a day; 2 cases of Enterococcus faecalis and 2 cases of Enterococcus faecium treated with intravenous drip of piperacillin and tazobactam sodium 4 500 mg 3 times a day, 2 cases of Escherichia coli treated with intravenous drip of levofloxacin 500 mg once a day. The duration of hospitalization of 9 patients ranged from 24 to 56 days. At discharge, LRINEC was significantly improved compared with admission, and LRINEC score was 0-2 points. Follow-up ranged from 3 months to 2 years, relapsed infection happended in the affected limb wound in one case, which healed after anti-infection and dressing change. The other cases healed well without recurrence. Conclusion:In the management of diabetic necrotizing fasciitis, concurrent comprehensive glycemic control and surgical intervention are crucial. The integration of vacuum sealing drainage and the employment of 1.5% hydrogen peroxide for wound cleansing, along with a consistent and prolonged antibiotics reatment course significantly contributes to improved disease control, promote wound healing, leading to reduced mortality and lower rates of amputation.
