Thermal trauma causes two different types of injuries within the burn wound. First, an immediate and irreversible injury, and, second, a delayed and partly reversible injury. It is a very common observation in burned patients that areas that initially seemed to be partial thickness burns have to be regarded as ...

Transcutaneous partial pressure of oxygen (TcPO2) predicts wound healing in critical ischemia. However, no studies have controlled for the effect of wounds on TcPO2. In this study, in 24 hip or knee arthroplasty cases without vascular disease, TcPO2 was measured preoperatively at the incision site, contralaterally, and at a reference ...

Because the skin is the athlete's first line of defense, it is exposed to friction and pressure in nearly every athletic setting. Whether applied acutely or chronically, friction and pressure often cause skin trauma, such as abrasions, chafing, calluses, blisters, talon noir (black heel), and acne mechanica. Sports medicine clinicians, ...

In this cadaver study, we compared 2 different acetabular cement pressurizers (Exeter and Bernoski type) in paired human acetabula with simulated intraosseous bleeding. Pressure transducers were used to record intra-acetabular pressures during pressurization. Anteroposterior radiographs of the entire specimens were taken. Subsequently, standardized 3-mm-thick sections were cut through the acetabula, ...

Over the past generation, there have been a number of significant advances in wound healing in general. Unfortunately, much of this has not translated into increased success in healing wounds on the sole of the foot. We believe that much of this therapeutic disconnect has to do with an inadequate ...

Acupuncture has been a major part of primary healthcare in China for thousands of years. The acupuncture points or biological active points (BAP), also known as low-resistance spots or good electro-permeable points, have relative lower electric resistance than the surrounding tissues. There are many factors that can affect the measurement ...

The lungs are surrounded by the pleural membranes. The visceral pleura directly covers the lung and is separated from the parietal pleura by a layer of surfactant, which reduces friction during respiratory movement. A potential space exists between these two layers, and they may become separated by fluid or air. ...

BACKGROUND: Application of the Vacuum-Assisted Closure device (VAC) to open sternal wounds has negative hemodynamic effects. We hypothesized that the interposition of a muscle flap attenuates these negative hemodynamic effects. MATERIALS AND METHODS: After institutional approval, monitoring lines were placed in anesthetized, ventilated pigs. Through a median sternotomy, sonometric crystals ...

Human living skin generates an increase in the skin potential when compressed. This was measured on eight subjects with a matrix of nine Ag/AgCl electrodes. The potential increased with the pressure until it reached a maximum. When the pressure was increased stepwise, the response showed an overshoot at each step. ...

During extravehicular activity (EVA), current space suits are pressurized with 100% oxygen at approximately 222 mmHg. A tight elastic garment, or mechanical counter pressure (MCP) suit that generates pressure by compression, may have several advantages over current space suit technology. In this study, we investigated local microcirculatory effects produced with ...

BACKGROUND:Reaming is regarded as the most adverse aspect of the intramedullary nailing procedure since it leads not only to impairment of the vessels but also to an increase in intramedullary pressure and cortical temperatures which may in turn lead to aseptic cortical necroses and pulmonary dysfunction. Intramedullary pressure increase is ...

Dressings tied over skin grafts reduce the size of dead space, prevent haematoma formation, and immobilize the grafts [McCarthy, Plastic Surgery, 1990]. Their mechanism of action was thought to include the application of pressure to the bed and stabilization of the graft and dressing. A quantitative analysis of the pressure ...

Cortical defects are common and problematic in cemented revision hip arthroplasty. Extruded cement can cause thermal injury, pain, and impingement. Decreased cement pressure limits bony interdigitation and leads to loosening. Historically, surgeons have used a finger to contain cement and improve pressure, and decrease porosity, but, with large or multiple ...

Seven bandage configurations were placed on the right forepaw of six English pointer dogs to evaluate the effects that configurations have on reducing pad pressure. The "clam shell" configuration resulted in less pressure being applied to all palmar pad surfaces. For the major weight-bearing pad, a basic paw bandage with ...

Foot compartment syndrome is a serious potential complication of foot crush injury, fractures, surgery, and vascular injury. The purpose of this article is to summarize and review the existing literature on this entity. Long-term sequelae of foot compartment syndrome (FCS) include contractures, deformity, weakness, paralysis, and sensory neuropathy. These complications ...

Diabetic foot and pressure ulcers are chronic wounds by definition. They share similar pathogeneses; i.e., a combination of increased pressure and decreased angiogenic response. Neuropathy, trauma, and deformity also often contribute to development of both types of ulcers. Early intervention and proper treatment should result in complete healing of non-ischemic ...

The healing process of telescopic anastomoses was found in an animal experiment with 12 mongrel dogs. After the division of vessels an ileal segment of different length was invaginated into the lumen of the colon using single-layer interrupted sutures. The following four groups were used: Group A (n = 3): ...
