Hand hygiene

6.7K
Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

Handwashing II: Pre-procedure and Initial Procedure Steps

1.7K
The pre-procedure steps of handwashing include removing jewelry and rolling up sleeves. However, many organizations allow staff to wear wedding rings.
The hand washing procedure itself includes the following steps. First, cover cuts, if any, on hands with a waterproof dressing. Cuts and abrasions can become contaminated with bacteria hindering the ability to clean the area thoroughly. In addition, repeated hand washing can worsen an injury.  The nails must be short and clean, without nail...

Cleaning, Sterilization, and Disinfection

13.7K
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...

Handwashing I: Introduction and Types of Equipment

5.3K
Handwashing is hand hygiene with plain or antimicrobial soap and water to physically remove dirt, organic material, and microorganisms. However, it may not kill all microorganisms. The handwashing procedure requires a hand wash basin, liquid soap, paper towels, a domestic waste bin, and disposable nail cleaner as optional equipment.
Hand wash basins in clinical areas should have faucets that can be turned on and off without using the hands; that is, they should be non-touch or lever-operated....

Area of Science:

  • Wound Healing and Tissue Repair
  • Microbiology and Infectious Diseases
  • Biomaterials and Medical Devices

Background:

  • Chronic wound management presents significant clinical challenges, particularly with bacterial bioburden and slough.
  • The TIME framework (Tissue, Inflammation/Infection, Moisture, Edge of wound) is essential for effective wound bed preparation.
  • Advances in wound care therapies offer new solutions for managing complex wounds.

Observation:

  • Bacterial bioburden and slough impede chronic wound healing.
  • Biofilms and slough are major obstacles in wound bed preparation.
  • The TIME framework guides clinicians in addressing wound bed challenges.

Findings:

  • A novel wound cleansing solution effectively reduces bacterial bioburden.
  • The solution demonstrates efficacy in breaking down microbial biofilms.
  • The cleansing solution aids in the debridement of slough from the wound bed.

Implications:

  • This wound cleansing solution offers a promising approach to improve chronic wound management.
  • It supports the principles of the TIME framework by addressing critical wound bed issues.
  • Enhanced wound bed preparation can lead to improved healing outcomes and reduced patient morbidity.
