Source: Madeline Lassche, MSNEd, RN and Katie Baraki, MSN, RN, College of Nursing, University of Utah, UT Central venous access devices (CVAD), commonly known as central lines or central catheters, are large-bore intravenous (IV) catheters that are introduced into the central circulation. Typically, CVADs terminate in the superior vena cava, just outside of the right atrium of the heart, but they may also terminate in any one of the great veins (i.e., aorta, inferior vena cava, brachiocephalic...

We describe a highly reproducible method for the permanent occlusion of a rodent major cerebral blood vessel. This technique can be accomplished with very little peripheral damage, minimal blood loss, a high rate of long-term survival, and consistent infarct volume commensurate with the human clinical population.

We demonstrate in the video a method for producing a middle cerebral artery occlusion in adult mice using an intraluminal monofilament. We also show how to evaluate the extent of cerebral infarction by 2,3,5-triphenyltetrazolium chloride (TTC) staining.
FAQs
Moisture retention can support the skin’s natural healing processes by preventing excessive fluid loss from injured tissue. The barrier also protects the wound surface from outside contaminants, which may improve comfort and help preserve a favorable local environment. This benefit must be balanced against drainage and infection concerns, because not every wound is appropriate for limited air and fluid exchange.
By reducing the exchange of air and fluids, an occlusive dressing can increase contact between a topical treatment and the skin. This may help a local product remain positioned over the intended area rather than being removed quickly. Clinicians still need to account for skin sensitivity and monitor the site, since prolonged or unsuitable coverage may not be appropriate.
Drainage, possible infection, skin sensitivity, and the need for regular monitoring are central considerations. A covering that supports moisture retention in one situation may be unsuitable when clinicians need to observe the site closely or manage substantial drainage. Selection therefore depends on the wound or skin condition, rather than on the barrier effect alone.
The covering can shield injured or delicate skin from external contact while helping limit moisture loss. That protection may improve comfort and reduce exposure of fragile tissue to environmental contaminants. Its value is greatest when the selected site can safely tolerate restricted air and fluid exchange, with monitoring maintained to identify problems that require a change in management.
Selection should match the clinical situation, including whether the site is a wound, burn, surgical area, or dermatologic condition. Clinicians should also assess drainage, infection risk, skin sensitivity, and how often the area requires monitoring. These factors determine whether the dressing’s protective and moisture-preserving effects are likely to support care without creating avoidable concerns.
Occlusive dressings may be selected for certain wounds, burns, surgical sites, and dermatologic conditions when protection, moisture preservation, or sustained topical contact is useful. Application should follow an assessment of the tissue and surrounding skin, followed by appropriate monitoring. The intended outcome is support for local healing or treatment while avoiding problems related to drainage, infection, or sensitivity.
