Aseptic techniques are methods used to prevent contamination by pathogens during medical procedures or laboratory experiments. These techniques are essential in maintaining a sterile environment, ensuring that harmful microorganisms do not enter wounds or cultures. Common practices include sterilizing instruments, using gloves, and working near a laminar flow hood to create a clean air environment. In healthcare, aseptic techniques are crucial during surgeries and when handling intravenous (IV) lines or catheters. By following these procedures, healthcare professionals can significantly reduce the risk of infections, promoting patient safety and improving outcomes. Proper training in aseptic techniques is vital for anyone working in clinical or laboratory settings.
