Negative-pressure wound therapy (NPWT) has revolutionised wound care. Yet, it is still not understood how hypobaric tissue pressure accelerates wound healing. There is very little reported on the relevant physics of any substance subjected to suction in this manner. The common assumption is that applying suction to a substance is ...

Prolonged mechanical loading of soft tissues adjacent to bony prominences can lead to degeneration of muscle tissue, resulting in a condition termed pressure-related deep tissue injury. This type of deep pressure ulcers can develop into a severe wound, associated with problematic healing and a variable prognosis. Limited knowledge of the ...

There are currently 2 main theories regarding the mechanism of action of negative pressure wound therapy with reticulated open cell foam (NPWT/ROCF) as delivered by V.A.C.(R) Therapy (KCI, San Antonio, TX). The first is based on the stimulatory effect of microstrain on cellular mitogenesis, angiogenesis, and elaboration of growth factors. ...

Pressure ulcers are localized skin injuries secondary to unrelieved pressure or friction. Patients with immobility issues are at increased risk for developing pressure ulcers. In 2004, stricter federal regulations for prevention and treatment of pressure ulcers in institutional settings--eg, long-term care facilities--were introduced. Effective, low-cost treatments for pressure ulcers are ...

We performed multiwavelength photoacoustic (PA) measurement for extensive deep dermal burns in rats to monitor the healing process of the wounds. The PA signal peak at 532 nm, an isosbestic point for oxyhemoglobin (HbO(2)) and deoxyhemoglobin (HHb), was found to shift to a shallower region of the injured skin tissue ...

Studies using quantitative sensory testing (QST) often present incongruent results due to intra- and intersubject as well as interobserver variability which limit widespread use of the technique. Eliminating or reducing the factors responsible for this variability is of great interest, as it increases reliability and reproducibility of QST. Thermal sensory ...

Luminal pressure may injure the gut mucosa in obstruction, ileus, or inflammatory bowel disease. We formed Roux-en-Y anastomoses in 19 mice, creating proximal and defunctionalized partially obstructed limbs and a distal limb to vary luminal pressure and flow. We induced mucosal ulcers by serosal acetic acid, and assessed proliferation (proliferating ...

The aim was to examine how changes in skin conductance, arterial blood pressure, and heart rate are associated with changes in the modified COMFORT sedation score during suction from the trachea. Nociceptive stimulation ...
Childress Beverly - - 2008
Compelling evidence suggests that nitric oxide (NO*), a metabolite of arginine, plays an important role in wound healing. Arginine is a semi-essential amino acid that is metabolized by nitric oxide synthase and arginase. One model for wound-healing regulation suggests the importance of strict reciprocal control of these enzymes in wounds. ...

Negative pressure wound therapy (NPWT) is an established modality in the treatment of challenging wounds. However, most existing clinical evidence is derived from the use of open-cell polyurethane foam at -125 mmHg. Alternative negative pressure systems are becoming available, which use gauze at a pressure of -80 mmHg. This study ...

In the prospective Royal Darwin Hospital snakebite study, pressure-immobilization first aid (PI) was used more often than in previous studies. However, bandages were not uncommonly too loose or not applied to the whole limb and immobilization was often neglected. While PI should continue to be promoted as the standard for ...
