INTRODUCTION: Although the use of negative pressure wound therapy (NPWT) is broadly efficacious, it may foster some potentially adverse complications. This is particularly true in patients with diabetes who have a wound colonized with aerobic organisms. Traditional antiseptics have been proven useful to combat such bacteria but require removal of ...

Open fractures frequently result in serious complications for patients, including infections, wound healing problems, and failure of fracture healing, many of which necessitate subsequent operations. One of the most important steps in the initial management of open fractures is a thorough wound irrigation and debridement to remove any contaminants. There ...

Negative pressure wound therapy (NPWT) is believed to initiate granulation tissue formation via macro-deformation of the wound edge. However, only few studies have been performed to evaluate this hypothesis. The present study was performed to investigate the effects of NPWT on wound contraction and wound edge tissue deformation. Six pigs ...

Higher levels of tourniquet pressure and higher pressure gradients beneath tourniquet cuffs are associated with a higher risk of nerve-related injury. Measurement of limb occlusion pressure can help to minimize tourniquet pressure levels and pressure gradients for individual patients and individual surgical procedures. Selective use of pneumatic, wider, and contoured ...

Compression bandaging is a major cornerstone in the treatment of chronic venous insufficiency. Its efficacy considerably depends on the applied pressure and it is therefore largely dependent on the individual applying the system. The sub-bandage pressure was measured under three consecutive compression bandages applied by 21 nurses before and after ...

A 56-year-old man became quadriplegic, bed bound, and carer-dependent secondary to cervical osteomyelitis. Three years later, he presented with generalised spasticity, crouched posture, and a large sacral pressure sore. The severe spasticity in his hips and knees prevented ischial sitting. Injections of botulinum toxin type A to both hamstrings and ...

Pressure ulcers are a significant healthcare concern, especially for elderly populations. Our work served to ameliorate the chronicity of these ulcers by addressing ischemia-reperfusion injury mediated by neutrophils and the concomitant loss of vasculature in these wounds. To this end, chitosan scaffolds loaded with basic fibroblast growth factor (bFGF) contained ...
