negative pressure wound therapy
Vacuum-assisted wound closure system using controlled suction to promote healing.
Full Definition
Negative pressure wound therapy (NPWT) is a therapeutic technique that uses controlled vacuum suction applied to wounds through a sealed dressing system. The negative pressure removes excess fluid, reduces bacterial load, and promotes granulation tissue formation. In acute care surgery, NPWT is commonly used for temporary abdominal closure, complex wound management, and fascial defect treatment. The therapy requires specialized equipment and trained nursing staff for safe application and monitoring. Documentation must include pressure settings, dressing changes, and wound progress assessments.
Usage
Usage note: Commonly abbreviated as NPWT or VAC; specify pressure settings and mode in clinical documentation.
