Combating Superbug Without Antibiotic on a Postamputation Wound in a Patient With Diabetic Foot

Abstract

Diabetic foot is a kind of limb- and life-threatening complication that is difficult to treat with conventional therapy, especially when accompanied with peripheral arterial insufficiency and severe infection. We present a diabetic patient with a postamputation wound infected by multidrug-resistant Acinetobacter baumannii/haemolyticus, which was resistant to almost all antibiotics. As the clinical response to antimicrobial therapy was poor, antibiotic was discontinued. Autologous platelet-rich gel with anticoagulation, negative pressure wound therapy, and improvement of microcirculation were used successfully to eradicate infection of the superbug and achieve final wound closure.
