If you have been stabbed by a patient with a used needle, you should follow the following steps to check. If the patient is hospitalized or can be contacted, check the patient’s past medical history for infectious diseases such as hepatitis B and C, syphilis, AIDS, etc. In addition, you can also do the above tests yourself. If there are no antibodies to hepatitis B, the hepatitis B vaccine should be administered in a timely manner because there is a certain window period for infection, so after doing the above tests, you can check again after one month to ensure safety. In addition, if you are wounded by a patient’s syringe, you should treat the wound promptly, flush it with running water, squeeze out the blood, and then disinfect it effectively with hydrogen peroxide and iodophor.
