Study Notes
Importance of Sterilization in Hospital Pharmacy
- Sterilization eliminates harmful microorganisms from pharmaceuticals and equipment, ensuring patient safety and infection prevention.
- Safe medication preparation in hospital pharmacies is paramount for effective treatment and care.
Importance of Sterile Compounding in Healthcare
- Patient Safety: Prevents infections due to contamination.
- Drug Efficacy: Contamination can degrade medications, reducing effectiveness.
- Compliance: Adheres to regulatory standards, guaranteeing quality.
- Diverse Applications: Sterile products apply to various treatments, including IV therapy, ophthalmic solutions, and injections.
Principles of Aseptic Technique
- Environmental Control: Clean controlled environments are maintained using HEPA filters and laminar airflow hoods.
- Hand Hygiene: Essential to wash hands properly and use sterile gloves to prevent contamination.
- Material Handling: Careful handling minimizes air exposure to maintain sterility.
- Verification: Continual monitoring for contamination sources and sterility procedures is critical.
Cleaning, Disinfection, and Sterilization Procedures
- Daily Cleaning: Routine dust and debris removal from surfaces, including countertops and equipment.
- Disinfection: Chemical agents are used to kill microorganisms after cleaning and prior to sterile compounding.
- Sterilization: Complete elimination of all microorganisms, including spores, mainly for equipment in direct contact with sterile products.
Gowning and Gloving Procedures
- Hand Hygiene: Wash hands with antimicrobial soap and water before dressing.
- Gown: A sterile gown should fully cover clothing, with sleeves reaching wrists.
- Gloves: Sterile gloves must be donned over gown cuffs while avoiding contamination.
- Verification: Inspect gowns and gloves for tears or punctures to ensure sterility.
Sterilization Methods
- Autoclaving: Utilizes high pressure and steam to sterilize heat-stable medications and equipment.
- Filtration: Filters solutions through a membrane to remove microorganisms and particulate matter.
- Radiation: Employs gamma rays or electron beams to sterilize heat-sensitive medications and devices.
Quality Control and Testing
- Sterility Testing: Culturing samples to identify microbial growth.
- Endotoxin Testing: Measures bacterial endotoxins that could induce fever.
- pH Testing: Assesses acidity or alkalinity of sterile solutions for stability.
- Particle Counting: Determines the number of particles in sterile solutions to ensure cleanliness.
Regulatory Requirements and Guidelines
- USP 797: Sets standards for sterile compounding, focusing on aseptic techniques and environmental controls.
- FDA Guidance: Offers recommendations for sterile compounding to ensure drug safety and effectiveness.
- Good Manufacturing Practices (GMP): Ensure quality and consistency in sterile compounding.
- Accreditation: Organizations like ASHP and USP recognize facilities that meet quality standards in sterile compounding.
