Patients with sepsis often require supportive care, which may include:

• Fluid Resuscitation: Intravenous fluids are essential to maintain blood pressure and organ perfusion, especially in septic shock.
• Vasopressors: If fluid resuscitation is insufficient to maintain adequate blood pressure, medications such as norepinephrine may be necessary.
• Monitoring: Continuous monitoring of vital signs, laboratory parameters, and organ function is critical in managing sepsis.

3. Source Control

Identifying and controlling the source of infection is vital. This may involve:

• Surgical Intervention: If there are abscesses or infected tissues, surgical drainage or debridement may be required.
• Discontinuation of Contaminated Products: In cases linked to animal exposure, ensuring that contaminated products are removed from the environment is crucial.

4. Adjunctive Therapies

In some cases, adjunctive therapies may be considered:

• Corticosteroids: While not routinely recommended, corticosteroids may be used in specific cases of severe sepsis to modulate the inflammatory response.
• Immunoglobulin Therapy: In patients with severe or recurrent infections, immunoglobulin therapy may be considered, particularly if there is an underlying immunocompromised state.

Conclusion

The management of erysipeloid sepsis (ICD-10 code A26.7) primarily revolves around effective antibiotic therapy, supportive care, and source control.
