What type of drainage occurs from an incision and drainage (I&D) of the leg?

From the Guidelines

Drainage from an incision and drainage (I&D) of a leg typically consists of purulent material (pus), which is a thick, opaque fluid that can range in color from yellow-green to brown, sometimes with blood streaking. This drainage contains white blood cells (primarily neutrophils), dead tissue debris, bacteria, and inflammatory exudate. The specific characteristics of the drainage may vary depending on the type of infection, with Staphylococcus aureus infections often producing thick, creamy yellow pus, while other infections may have different appearances and odors 1. Initially after the I&D procedure, the drainage may be more bloody (serosanguineous), gradually transitioning to purulent and then serous (clear, watery) as healing progresses. The volume of drainage typically decreases over time as the infection resolves and the wound heals. Some key points to consider in the management of skin and soft tissue infections include:

• Incision and drainage is the primary treatment for simple abscesses or boils, and antibiotics are not needed for these cases 1
• Empiric therapy for community-acquired MRSA (CA-MRSA) should be recommended for patients at risk for CA-MRSA or who do not respond to first line therapy 1
• The choice of antibiotic therapy should be guided by the severity of the infection and the suspected or confirmed causative pathogens 1 Persistent or increasing drainage, especially if accompanied by increasing pain, redness, or swelling, may indicate ongoing infection requiring further medical attention. It's worth noting that the management of skin and soft tissue infections should be individualized based on the specific clinical presentation and patient factors, and that the guidelines provided by the Infectious Diseases Society of America and other organizations should be consulted for more detailed information 1.

From the Research

Types of Drainage from I&D of Leg

• The type of drainage from an incision and drainage (I&D) of a leg abscess can vary depending on the underlying cause of the infection and the presence of any complications 2.
• In general, the drainage from an I&D of a leg abscess can be purulent, serous, or bloody 2.
• The amount and characteristics of the drainage can also provide clues about the effectiveness of the treatment and the presence of any potential complications.

Factors Influencing Drainage

• The choice of dressing used to manage the wound after I&D can influence the type and amount of drainage 3.
• The use of antimicrobial dressings or topical antibiotics may help to reduce the risk of infection and promote healing 3, 4.
• The presence of underlying conditions, such as diabetes or immunocompromised states, can also affect the type and amount of drainage 4, 5.

Clinical Implications

• The type and amount of drainage from an I&D of a leg abscess can have important clinical implications, including the need for ongoing antibiotic therapy or further surgical intervention 6, 2.
• Close monitoring of the wound and drainage is essential to ensure prompt detection and management of any potential complications 6, 2.
