Preparing for surgery is a critical step in ensuring the safety of both the patient and the medical staff. Scrubbing is an important part of the process, which involves washing the hands and arms with soap and water to remove dirt and germs. Sterilizing is the next step, which involves using heat or chemicals to kill any remaining bacteria or viruses. Finally, scrubbing up involves putting on sterile clothing and gloves to protect against contamination. All of these steps are essential for a successful surgery.
