NPWT
Also written as: NPWT — Negative-Pressure Wound Therapy
Negative-pressure wound therapy system applying controlled suction to wound beds. Promotes granulation tissue formation and wound contraction.
Full Definition
Negative-pressure wound therapy (NPWT) is a therapeutic modality that applies controlled sub-atmospheric pressure to wound surfaces through a sealed dressing system. The technique promotes wound healing through multiple mechanisms including enhanced perfusion, removal of excess interstitial fluid, and mechanical stimulation of granulation tissue formation. NPWT is commonly employed in dermatologic surgery for complex reconstructions, compromised wound healing scenarios, and as a bolster dressing for skin grafts. The system typically consists of a foam or gauze interface, occlusive drape, and computerized pump unit.
Usage
Usage note: Spell out on first use in clinical documentation.
