Topical Negative-Pressure Therapy in Wound Management

摘要: Surgical practice has long recognised that healing is promoted by removing fluid collections from a wound site in the post-operative period while maintaining moist environment. In addition, observation tissue growth responds positively to applied mechanical forces (a permutation of Wolff's Law), as osteogenic distrac­ tion and soft-tissue expansion, led variety negative-pressure wound­ therapy systems being designed [4-9]. The philosophies underpinning early development TNP differed subtly between North American European groups. approach was principally concerned with developing for managing difficult, complex wounds, an emphasis on improving granula­ tion-tissue formation, exudate management, infection control closure [10, 11]. concept can be characterised acute high-energy contaminated injuries where haemostasis in­ fection are at premium [12]. From mid 1990s majority published research examining focused use purpose-built programmable vacuum pumps. These devices deliver predetermined negative pressure across surface planned - either cyclical or constant man­ ner. This facility encouraged more structured scientific examination produced body its core. Within literature clinical number synonyms [1] presently use, including: sub-atmospheric [10], -sealing tech­ nique (VST) [12], sealed suction (SSS), vacuum-assisted (VAC), pack [13], dressing foam [2,14].
