Study Notes
Symbiotic Relationships
- Tapeworms living in a human host exhibit a parasitic relationship.
Thermophiles
- Thermophiles are organisms that thrive in high temperatures ranging from 40 to 70 degrees Celsius.
Barophiles
- Barophiles are organisms that flourish in high atmospheric pressure environments.
Disinfectants
- Alcohol-based disinfectants are effective when applied for 30 seconds to 1 minute.
- Phenols are categorized as low-level disinfectants.
- Hydrogen peroxide is a chemical agent used as a high-level disinfectant.
Pyrogens
- Pyrogens are fever-inducing substances often derived from bacteria.
Nosocomial Infections
- A nosocomial infection is an infection acquired in a healthcare setting.
Laminar Airflow Hoods
- "First air" in a laminar airflow hood provides HEPA-filtered air directly to critical sites.
Isotonic Solutions
- Isotonic solutions used in sterile products have the same tonicity as blood.
Sterilization Methods
- Freeze-drying (Lyophilization) involves dehydration and freezing in a vacuum.
- Pre-filters in laminar airflow hoods filter out large particles and contaminants before air passes through the HEPA filter.
Gram-Negative Bacteria
- Escherichia coli (E.coli) is an example of Gram-negative bacteria.
Cleanrooms
- Cleanrooms are controlled environments where air is filtered and maintained to prevent contamination.
pH of Injections
- The ideal pH range for injectable solutions is 3-8 to ensure compatibility with the human body.
Particle Count in ISO Class 5 Environments
- The maximum allowable particle count in ISO Class 5 environments is 3,520 particles per cubic meter of air.
Laminar Airflow
- Laminar airflow in cleanrooms ensures that air flows in parallel, uniform layers, creating a controlled environment.
Bacteriostatic Water for Injection
- Bacteriostatic water for injection contains preservatives to prevent bacterial growth.
Stability of Sterile Products
- Oxidation is a crucial factor in the stability of sterile products.
Sterilization Methods
- Cold sterilization (using chemical agents) is best suited for materials that cannot withstand high temperatures.
Pyrogens in Sterile Compounding
- Pyrogens are a primary concern in sterile compounding due to their ability to cause septic shock and fever.
Iso-osmotic or Isotonic Solutions
- The term "iso-osmotic" or "isotonic" refers to a salt concentration similar to blood in sterile preparations.
Urinary Tract Infections (UTIs)
- Escherichia coli (E.coli) is a common pathogen associated with urinary tract infections in healthcare settings.
Particulate Matter
- Particulate matter in sterile products refers to microscopic particles such as dust, fibers, or rubber.
Parasitic Infections
- Parasitic infections are caused by organisms like tapeworms or scabies that live at the expense of the host.
Vehicles in Sterile Products
- Aqueous and non-aqueous solutions are used as vehicles in sterile products to serve as solvents and carriers.
Storage of Sterile Products
- Medium-risk level sterile compounded products are typically stored under refrigeration for 9 days or less.
Contamination Prevention in Sterile Compounding
- Wearing appropriate protective garb (gowns, gloves, masks) is crucial for preventing contamination during sterile compounding.
Mutualistic Relationships
- In a mutualistic relationship, both organisms benefit from the interaction.
Hypertonic Solutions
- Hypertonic solutions in sterile compounding have a higher salt concentration than blood.
Freeze-Drying (Lyophilization)
- Freeze-drying (lyophilization) is used in sterile compounding to remove moisture and extend the shelf-life of a product.
Gram-Positive Bacteria
- Staphylococcus aureus is an example of Gram-positive bacteria.
ISO Class 5 Environments
- ISO Class 5 environments are ultra-clean environments maintained for compounding sterile products.
Nosocomial Infections
- Nosocomial infections are commonly associated with surgical wounds in healthcare facilities.
Moist Heat Sterilization (Autoclaving)
- Moist heat sterilization (autoclaving) is highly effective for sterilizing aqueous solutions.
Sporadic Infections
- A sporadic infection occurs infrequently and irregularly in a population.
