Asepsis refers to the practice of preventing contamination by pathogens, ensuring a sterile environment. It is crucial in medical settings, such as during surgeries or when handling open wounds, to minimize the risk of infections. Techniques include sterilization of instruments, use of disinfectants, and maintaining clean surfaces. There are two main types of asepsis: medical asepsis and surgical asepsis. Medical asepsis focuses on reducing the number of pathogens, while surgical asepsis aims to eliminate all microorganisms. Both practices are essential for patient safety and effective healthcare delivery.
