Standard Precaution

Standard Precaution

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...

Asepsis

Asepsis

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.

Cleaning, Sterilization, and Disinfection

Cleaning, Sterilization, and Disinfection

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...

Hand hygiene

Hand hygiene

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.

Healthcare Associated Infections II: Preventive Measures

Healthcare Associated Infections II: Preventive Measures

Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...

Area of Science:

Perioperative Nursing
Surgical Safety
Infection Control

Background:

Sterile technique is crucial for reducing contamination in operating rooms.
Adherence to sterile technique principles is fundamental for safe patient care in perioperative settings.

Purpose of the Study:

To provide an overview of the updated AORN "Guideline for sterile technique."
To discuss recommendations for implementing sterile technique in perioperative nursing.

Main Methods:

Review of the AORN "Guideline for sterile technique."
Discussion of recommendations for sterile field preparation, maintenance, and limiting movement.
Inclusion of a scenario on isolation technique for colon procedures.

Main Results:

The guideline details principles and processes for sterile technique.
Recommendations cover actions before, during, and after sterile field preparation.
Specific guidance is provided for surgical wound classification and quality assurance.

Conclusions:

Perioperative nurses must thoroughly review and apply the updated AORN guideline.
Implementing these recommendations enhances sterile technique and patient safety during operative procedures.
