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...

Burch in their book The Principles of Humane Experimental Technique. The 3 R's are replacement, reduction, and refinement of the use of animals in research. The use of cell lines and tissue cultures that originated from research animals is a replacement technique, as it allows for many experiments to be conducted in vitro. Harvesting...

Cleaning, disinfection, and sterilization are the methods that help to break the infection chain and prevent disease. Cleaning The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...

Methods of Sterilization II: Chemical Methods

In healthcare, the chemical method of sterilization uses chemical sterilants to treat surgical instruments and medical supplies to help prevent the transmission of infectious pathogens to patients. Due to heat sensitivity, most medical supplies and equipment should not be exposed to high temperatures. These parts include rubber, plastic, glass, and other similar elements. Using chemical sterilization rather than heat to clean out equipment is recommended. It eradicates and removes all bacteria,...

Methods of Sterilization I: Physical Methods

As used in a healthcare facility, sterilization destroys all microorganisms through physical or chemical methods. The physical method includes steam, dry heat, boiling water, and radiation. Steam sterilization uses non-toxic, low-cost moist heat in the form of saturated steam under pressure, which is fast, microbicidal, and sporicidal, and quickly warms and penetrates fabrics. Autoclaves, or steam sterilizers, expose each item to direct steam contact for a predetermined time at the necessary...
FAQs
Aseptic technique limits the introduction of microorganisms during application and replacement, preserving the dressing’s clean protective role. Once positioned, the covering forms a barrier over vulnerable tissue, helps shield the site from contamination and friction, and reduces the chance of additional tissue damage. This is especially important when newly formed tissue remains exposed to the surrounding environment.
Moisture and drainage influence whether a dressing can support healing without becoming unsuitable for the wound. Absorbing exudate helps manage fluid at the site, while selected dressings may maintain moisture that supports tissue repair. Clinicians therefore consider the amount of drainage and the tissue condition when choosing materials and deciding how often replacement is needed.
Selection depends on wound location, the amount of drainage, tissue condition, and how often the site requires attention. A dressing for a particular location must provide appropriate protection, while drainage and tissue status guide its handling and replacement schedule. Matching these factors helps maintain a clean environment, protect the wound, and support ongoing clinical assessment.
Replacement renews the covering’s protective function and gives clinicians an opportunity to assess the wound rather than leaving the site unexamined. When performed with aseptic technique, it helps limit contamination during care, protects newly formed tissue, and accommodates changes in drainage or tissue condition. The process also supports timely recognition of complications that may require clinical response.
Clinical teams commonly apply them after surgery, injury, or invasive procedures, when tissue may need protection during healing. The appropriate covering and replacement schedule depend on the wound’s location, drainage, and condition. In each setting, the dressing helps protect the site while allowing care providers to maintain a clean environment and monitor progress over time.
Each replacement creates a structured opportunity to observe the wound and compare its condition over time. Clinicians can consider tissue status, drainage, and the continued need for protection while selecting the next dressing and schedule. This repeated assessment helps preserve newly formed tissue, identify changes that may indicate complications, and guide appropriate clinical response.
