The inflammation then slowly begins to settle into the proliferative and re-epithelialization phases of wound healing. This involves neutrophils and various cytokines and occurs over the first seven days after the injury.

An acute injury to the skin initially induces a proinflammatory cascade comprising hemostasis followed by inflammation. Wound healing is divided into acute and chronic phases.

These microscopic processes, in turn, contribute to the macroscopic processes involved in the continual daily maintenance of skin, including wound healing. Each layer has its unique structure and cellular composition, contributing to its characteristic function within the epidermis. The epidermis is further subdivided into (from superficial to deep) stratum corneum, stratum lucidum, stratum granulosum, stratum spinosum, and stratum basale. The skin is a laminated structure, comprising (from superficial to deep) the epidermis, dermis, and hypodermis, which is also referred to as the subcutaneous or fatty tissue layer. This article explains the mechanism of NWPT along with the indications, contraindications, and practical approaches to this advanced wound care modality. NPWT provides an impactful and exciting development in wound care, with different clinical applications. Negative pressure is then applied at 125mmHg below atmospheric pressure for a sustained duration of up to six hours, after which the fluid instillation recurs. This comprises the direct administration of saline or antibiotic-containing solution into the wound bed, followed by a period of time ranging from ten to twenty minutes to allow for the distribution of the solution throughout the wound. Īn emergent adaptation of NPWT is using fluid instillation in conjunction with NPWT to enhance the therapy delivered. While the available evidence shows equivocal results for wound healing, this wound management system has seen a widespread implementation for closed wounds prone to dehiscence or infection secondary to exudate and localized inflammation. This aims to reduce edema and seroma formation, prevents surgical dihisence in high-risk incision sites, and promote granulation to encourage healing. In more recent years, NPWT has also been adapted for the adjunctive treatment of closed wounds, such as closed surgical incisions and skin grafts. Additionally, disposable wound VACs, either battery operated or purely mechanic suction, are available for use and typically used for smaller wounds. The material from which the foam is derived is either polyurethane (PU) (black) or polyvinyl alcohol (PVA) (white).

More modern iterations of this system now offer advanced options to enhance the delivery of the NPWT, such as a range of pressure settings from -40mmHg to -200mmHg, which can be tailored for different types of wounds. It is usually performed in the operating room, given the fact that the wounds usually require debridement and a washout in a sterile environment. Termed Vacuum-Assisted Closure (often abbreviated to “VAC”), this system is only effective if applied correctly by trained individuals. The system has seen widespread uptake and is now implemented routinely for open wounds, such as open fractures, fasciotomies, ulcers, and infected wounds. This type of NPWT system comprises a porous foam dressing upon which continuous or intermittent suction is applied through an electronically powered suction device to achieve a sub-atmospheric pressure of 125mmHg below ambient pressure. The most recent iteration of NPWT is courtesy of Argenta and Morykwas, who demonstrated its efficacy in their paper published in 1997. NPWT has undergone a significant evolution since the first modern-day recorded application of this concept in the 19 century. It can be utilized to manage acute and chronic wounds, ranging from open fasciotomy wounds and diabetic foot ulcers to closed surgical incisions.

Negative pressure wound therapy (NPWT) is a broad term used to describe a unique and versatile system that aids the optimization of wound healing through the application of sub-atmospheric pressure to help reduce inflammatory exudate and promote granulation tissue.
