Study Notes
Germicidal Chemicals and Antimicrobial Medications Overview
- Sterilants destroy all microbes, including heat-sensitive critical instruments
- High-level disinfectants destroy viruses and vegetative cells, but do not reliably kill endospores
- Intermediate-level disinfectants destroy vegetative bacteria, mycobacteria, fungi, and most viruses, and are used for semi-critical instruments
- Low-level disinfectants destroy fungi, vegetative bacteria except mycobacteria, and enveloped viruses, and are used for non-critical instruments
- There are 25 classes of germicidal chemicals, including alcohols, aldehydes, biguanides, and ethylene oxide
- Chlorine, iodine, metal compounds, peroxygens, and phenolic compounds are also used as germicidal chemicals
- Refrigeration inhibits the growth of pathogens and spoilage organisms, and freezing preserves by stopping all microbial growth
- Antimicrobial medications have revolutionized the treatment of common diseases, such as bacterial pneumonia and severe staphylococcal infections
- The discovery of antimicrobial medications dates back to the early 20th century, with the development of chemotherapeutic agents
- The discovery of antibiotics began with Fleming's identification of penicillin in 1928, which was later purified and tested in the 1940s
- The availability of penicillin in the 1940s revolutionized the treatment of infectious diseases
- Misuse and the evolution of microbial resistance threaten the effectiveness of antimicrobial medications, leading to the urgent development of new medications
