Occlusive bandaging of wounds with decreased circulation promotes growth of anaerobic bacteria and necrosis: case report

Background Topical occlusive/semi-occlusive dressings that induce a damp and trapped environment are widely used in wound treatment. Subjecting the wound with impaired circulation to such trapped/air-free environment potentiates the growth of anaerobic bacteria and risk for serious infection. Case presentation We present a case of previously healthy Swedish male that had a muscle contusion after heavy trauma that induced impaired circulation. The application of an occlusive bandage to the post-traumatic wound on the patient resulted in a poly-microbial anaerobic infection and necrosis. These complications were treated successfully with antibiotics and open dressing of the wound. Conclusion The pathophysiology of difficult- to- treat ulcers should be reviewed by the physician and occlusive dressing should be avoided when treating wounds with impaired circulation.
