Aseptic technique is a set of practices used to prevent contamination by pathogens during medical procedures or laboratory experiments. This method is crucial in maintaining a sterile environment, ensuring that microorganisms do not interfere with results or cause infections. Common practices include sterilizing instruments, using gloves, and working near a flame to create an upward airflow that helps keep contaminants away. In healthcare settings, aseptic technique is vital for procedures like surgeries and injections. It involves careful handwashing, wearing masks, and using sterile equipment. By following these guidelines, healthcare professionals can minimize the risk of infection and promote patient safety, especially in procedures involving surgical instruments or intravenous lines.
