Asepsis01:28

Asepsis

3.6K
The condition of being free from disease-causing living pathogens is asepsis. Aseptic techniques include a set of standard practices to achieve asepsis. An example is the regular environmental cleaning of all parts of the healthcare facility and hand hygiene at home before preparing or eating food. Medical and surgical asepsis in healthcare practice protects patients from harmful pathogens, minimizes the risk of contamination of susceptible sites, and reduces the risk of infection transmission.

Standard Precaution01:26

Standard Precaution

3.2K
Standard precautions are the minimum infection control safeguards used while caring for all patients, irrespective of their disease condition. They help prevent the spread of common infectious microorganisms to healthcare workers, patients, and visitors in all healthcare settings.
Hand hygiene is the most crucial means to prevent the transmission of disease. Employers are legally required to provide their workers with personal protective equipment (PPE) to minimize exposure or contact with...

Tracheostomy Care II: Procedure

2.0K
Tracheostomy care is an essential nursing skill that involves cleaning and maintaining a tracheostomy tube to prevent infection and other complications. Here's a step-by-step guide explaining each procedure with its rationale. Note that disposable gloves are to be worn at all times and changed as often as needed to maintain a sterile work environment, and to protect both patient and healthcare worker.
Step 1: Perform hand hygiene, and put on personal protective equipment: gown, gloves, mask...

Hand hygiene01:23

Hand hygiene

6.3K
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.

Cleaning, Sterilization, and Disinfection

11.5K
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...

PPE Use in Healthcare Settings II: Doffing01:10

PPE Use in Healthcare Settings II: Doffing

1.7K
The sequence of removing or doffing PPE starts with the gloves, as they are the most contaminated. Next is removal of the face shield or goggles, as they would interfere with removing other PPE. Then remove the gown, followed by the mask or respirator. Perform hand hygiene between steps if hands become contaminated and immediately after removing all PPE. Generally, the outside front and sleeves of the isolation gown, the goggles or the mask, the respirator, and the face shield are contaminated.

Area of Science:

  • Anesthesiology
  • Infection Control
  • Patient Safety

Background:

  • Perioperative infection reduction strategies, including hand hygiene, have shown limited efficacy.
  • Focus is shifting towards environmental contamination control during anesthesia procedures.

Purpose of the Study:

  • To evaluate the effectiveness of a barrier device in reducing contamination of the anesthesia workstation.
  • To assess the potential impact of environmental contamination reduction on patient safety during intubation.

Main Methods:

  • A simulated operating room environment was used with 42 anesthesiologists.
  • Participants performed simulated induction and intubation, with or without a barrier device covering the anesthesia workstation.
  • Fluorescent markers simulated bacterial contamination, and ultraviolet light assessed spread to 14 sites.

Main Results:

  • The barrier group showed significantly lower contamination rates (19.4%) compared to the control group (44.8%) (P <0.001).
  • Significant reductions in contamination were observed at several key clinical sites.

Conclusions:

  • A barrier device for the anesthesia workstation can effectively reduce intraoperative environmental contamination.
  • This intervention may serve as a valuable tool to improve operating room hygiene and patient safety.
