The electrostrictive effects in anisotropic tissue, such as muscle, are interesting and qualitatively different than in an isotropic material. A striking feature in anisotropic tissue is the presence of a charge distribution, which is absent in isotropic tissue. This charge interacts with the electric field to give rise to body ...

Selecting the "ideal dressing" for a wound is based on considerations of specific factors, including presence of necrotic tissue, bacterial load, volume of exudate, and the need for a bacterial barrier. Many dressings are now available, including hydrocellular foam dressings, that possess multiple characteristics of the ideal dressing. This article ...

We used negative-pressure dressings to treat a poorly healing cervical rotation flap following radical neck dissection in an elderly man. The wound had failed to heal properly after 2 weeks of conservative management. Following application of the negative-pressure dressings, the wound granulated quickly and healed well by secondary intention.
Schult Marc - - 2006
Although reamed intramedullary nailing has been one of the greatest advances in modern fracture care, the concomitant increase in medullary cavity pressure leads to intravasation of bone marrow content into the blood stream, an effect that can evoke serious systemic reactions. A newly developed rinsing-suction-reamer (RSR) was able to substantially ...

To reduce pressure-related injuries resulting from pneumatic tourniquet use, the lowest possible inflation pressure is recommended. Arterial occlusion pressure (AOP) is a measure of the cuff pressure required to maintain a bloodless surgical field. However, its determination method is time consuming, requires operator skill, and is therefore seldom used in ...
