THE CLEANING OF INSTRUMENTS AND SYRINGES
Journal of Clinical Pathology
|January 1, 1965
Summary
Routine syringe handling poses minimal risk. However, infected or antibiotic-contaminated syringes require autoclaving due to pathogenic organisms. Mechanical cleaning methods, including ultrasonics and detergents, are crucial for effective syringe and instrument decontamination.
Area of Science:
- Healthcare-associated infection control
- Sterilization and disinfection techniques
- Medical device reprocessing
Background:
- Syringes and medical instruments pose infection risks if not properly cleaned.
- Previous cleaning methods may be insufficient for certain contaminants.
- Understanding optimal reprocessing is vital for patient and handler safety.
Purpose of the Study:
- To evaluate the safety of routine syringe handling.
- To assess the efficacy of mechanical cleaning methods for syringes and instruments.
- To identify optimal detergents and procedures for decontamination.
Main Methods:
- Development of an artificial soil for standardized contamination testing.
- Evaluation of ultrasonic cleaning, with and without agitation.
- Assessment of various detergents (Pyroneg, Penesolve 814) and rinsing protocols.
Main Results:
- Routine syringe handling risks are negligible.
- Ultrasonics alone are insufficient; agitation is essential for syringes but not instruments.
- Pyroneg is effective for syringes, especially siliconized ones. Penesolve 814 at 95°C is best for instruments, requiring thorough rinsing.
Conclusions:
- Infected or antibiotic-contaminated syringes necessitate autoclaving.
- Detergents are essential adjuncts to ultrasonic cleaning for both syringes and instruments.
- Specific detergents and conditions optimize decontamination, ensuring safer medical practices.

01:28Asepsis
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.
01:23Hand 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.

01:18Handwashing I: Introduction and Types of Equipment
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.

01:30Cleaning, 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...

01:30Methods 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,...

01:26Standard 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.
