2024年5月7日 · What is skin shearing or a shearing wound? A shearing wound damages the skin on a deeper level. Shearing occurs when tissue layers laterally shift in relation to each other; as when bone and deep tissue layers move in opposite directions.

2019年3月22日 · Skin injury leading to chronic wounds has numerous causes, including moisture, pressure, shear, friction, and blunt force. Ongoing skin assessments and care planning, as well as best practice techniques, are key to prevention or treatment of these injuries.

2017年1月26日 · It’s a common question among wound care providers: what exactly is the difference between friction and shearing? These two conditions are common with limited mobility patients, and often contribute to the development of pressure ulcers.

Wounds caused by shear usually go undetected since they occur in the deeper layers of our tissue. We are used to seeing a wound start superficially and only begin to take treatment steps once we see the reddening of the skin. Here is a great diagram comparing pressure and shear.

Mostly shearing injury appears at an area where a bone point is prominent to create the pressure when moving causing the skin to separate. However, shearing can occur anywhere on the body. There are some techniques that can be used to avoid friction or shearing injury.

We most likely have friction, shear, and moisture going on with this patient. This scenario is the perfect recipe for a pressure injury. So what can we do to help this patient and prevent a pressure injury from developing? We must first identify the cause, and then remove the cause.

2019年1月3日 · Often pressure injuries caused by shear can be more dangerous than pressure alone. Let’s recall what shear is. Shear, by definition, is a combination of downward pressure AND friction and occurs while a patient is in movement in the wheelchair system. Shear commonly occurs in the wheelchair system:

Using the right dressing for wounds as part of an overall pressure injury prevention protocol is a cost-effective intervention that can keep patients safe. It helps protect against friction and shear and prevent the skin breakdown that leads to PIs.

2020年8月1日 · Shear is the sideways force that takes place at right angles to pressure (Fig. 2). Static friction, where skin and support surfaces meet, ‘grabs’ the respective surfaces and distorts the deeper materials sideways: this kind of distortion is called shear strain (Fig. 3).

Shear. Shear is a mechanical force that has internal effects on the skin in a direction parallel to the body’s surface. Shearing forces occur between internal body structures and the skin. Typically the shearing force and the body move in opposite directions. These forces influence deeper tissues via a “bottom-up” mechanism of tissue injury.
