washout procedure
Surgical irrigation and debridement of infected or contaminated body cavities or wounds.
Full Definition
A washout procedure involves systematic surgical irrigation and debridement of infected or heavily contaminated anatomical spaces to remove debris, infected material, and reduce bacterial load. This technique is fundamental in treating intra-abdominal infections, infected surgical sites, empyema, and contaminated traumatic wounds. The procedure typically includes copious irrigation with warm saline or antibiotic solutions, mechanical removal of infected tissue and debris, and often placement of drains for continued evacuation. In cases of severe contamination or established infection, multiple washout procedures may be required at regular intervals until the infectious process is controlled. The goal is to convert a contaminated or infected environment into one conducive to healing, often serving as a bridge to definitive reconstruction or closure.
Usage
Usage note: Often used more broadly than specific 'irrigation and debridement' to include cavity lavage.
