Why is it antibiotic resistant?

John Jones, age 32, is admitted to your ward  after post-surgical lancing of a cutaneous abscess located on his perineum.  The abscess was caused by MRSA bacteria.  The abscess required excision and drainage to remove pus and debris.

Mr. Jones is under police guard as he has been on remand at the nearby Correctional Centre for the past 2 days awaiting trial related to holding an illegal drug.  Mr. Jones has a history of IV heroin use and homelessness. He states that he last used heroin “about 4 days ago”.  Mr. Jones’s medical history reveals that he has previously been admitted to hospital for depression and a suicide attempt.  His blood tests returned positive for Hepatitis C.  Insulin levels are within the normal range and chest x ray returned clear.  His BMI is 20kg/m2, weight is 65kg and height 180cm.

You read the surgeon’s post-operative instructions:

Wound cavity to be dressed daily with Betadine-soaked gauze packing

Mr. Jones  is visited by the wound management nurse who documented the following in his notes:

Wound to heal by secondary intention

Wound cavity measures 12mm long x 11mm wide and 10mm deep, extending to the subcutaneous tissue layer

Wound bed consists of 100% granulation tissue; is malodorous and is oozing large amounts of haemoserous exudate.

Based on this assessment, the wound management nurse disagreed with the surgeon’s post-operative wound management strategy.
