What should you know about osteomyelitis pseudomonas?

Pseudomonas is a type of bacterium that can infect bone, especially when infection follows an open wound, a procedure, prolonged tissue exposure, or contact with healthcare environments. The name alone does not describe how extensive the infection is. Clinicians consider the sample source, culture result, antibiotic susceptibility, affected bone, wound, implant, and your overall health.

A swab from the skin may not represent bacteria deeper in the bone. A deep tissue or bone sample can be more useful when it is safe and appropriate. The team may also investigate whether dead bone, an abscess, or an implant is maintaining the infection.

Use only the antibiotic plan prescribed for your result and attend reviews for response and medicine-related problems. Do not share antibiotics or stop them because pain has improved. Tell the team about diarrhoea, rash, breathing difficulty, severe weakness, or other new symptoms after a dose. Wound care, drainage, removal of unhealthy tissue, and protection of the bone may be needed alongside antimicrobial treatment.

If infection leaves a bone defect after the infected tissue is addressed, the surgeon may discuss reconstruction, including selected [Bone Grafting](/treatments/trauma-and-fracture-care/bone-grafting/).

Contact your treating team quickly for returning fever, worsening deep pain, increasing redness or swelling, or new drainage. Seek urgent care if you feel severely unwell, have confusion, faintness, breathing difficulty, or a limb that becomes cold, pale, numb, weak, or difficult to move.

Was Pseudomonas found in a deep sample or a surface swab? Which antibiotics is it susceptible to? Is drainage or surgery needed? How will you monitor the infection and medicine effects?
