Final answer:
For general handwashing, the CDC advises a minimum of 20 seconds scrubbing time using soap. In healthcare settings, especially prior to surgery, the scrubbing protocol is more involved and time can vary. Regular handwashing is vital for preventing the spread of pathogens.
Step-by-step explanation:
Duration of Scrubbing for Hand Hygiene:
When performing hand hygiene, the duration of scrubbing is crucial for effective cleansing. For general handwashing, the Centers for Disease Control and Prevention (CDC) recommend that individuals should scrub their hands with soap for at least 20 seconds. A familiar way to time this is by humming the "Happy Birthday" song twice. However for healthcare workers, especially when preparing for surgery surgical scrubbing is more extensive. The length of time for a surgical scrub can vary depending on the antimicrobial product used but frequently goes beyond the minimum of routine handwashing. The goal is to significantly reduce the microbiota on the skin to prevent potential infection. It's essential to cover all areas of the hands, including thumbs wrists, between fingers and under fingernails.
You may use a nail brush to clean under the fingernails effectively. After scrubbing, rinse your hands thoroughly, ensuring the water flows from wrists to fingertips. Dry your hands with a clean towel or an air blower and use a towel to turn off the tap and open doors to avoid recontamination. Handwashing is a key preventive measure against the spread of pathogens which can survive on surfaces for several hours and should be performed regularly throughout the day particularly before and after certain activities as recommended by the CDC.
