Today I read the newspaper and saw the news “Pregnant woman with AIDS conceals her condition, stains doctor’s wound with blood”. I felt a lot of emotions after seeing the report. Pregnant women conceal their HIV history, probably because they are afraid of social discrimination. Even now everyone says that society does not discriminate against HIV patients, but there is a saying that “emphasis is absence”, discrimination really exists, and it is unfair to people with HIV, so some people choose to conceal it. The infected person is pathetic. The blood-stained doctor’s wound proves once again that the medical industry is a high-risk industry, in addition to becoming a defendant, being physically injured, but also working with injuries, dealing with various bacteria and viruses every day, the chance of infection is much higher than normal people. Doctors are poor. But, after all, we can’t blame the occupational exposure on the patient’s concealment. Put yourself in their shoes and think about the painstaking teachings of the hospital infection office teachers all day long, and think about the unannounced hospital-acquired inspections over and over again, at this point, I’m afraid we understand that they are truly dedicated and responsible for their patients, their doctors, and all participants in medical activities. I don’t know if you remember the term “standard precautions” that is always asked in every inspection. I think that if all medical personnel involved in the medical process could always tighten the string of standard precautions, the chances of tragedies would be greatly reduced. Today, I was really touched. I have carefully reviewed the concepts of occupational exposure and standard precautions. Finally, I sincerely wish our medical and nursing colleagues good health and safety, wish the patients to recover soon, and wish the doctors and patients to be in harmony soon! Once again, I would like to express my sincere gratitude to Prof. Su-Min Li of the Infection Office of the Third Affiliated Hospital of Xinxiang Medical College for her hard work in teaching infection knowledge. Standard prophylaxis: It is considered that the patient’s blood, body fluids, secretions and excretions are infectious and need to be isolated, regardless of whether there is obvious blood, contamination, contact with non-intact skin and mucous membranes, and those who come into contact with the above substances must take preventive measures. Isolation objects: all patients’ blood, body fluids, secretions and excretions are considered infectious and need to be isolated. 2 Protection: Implement two-way protection to prevent two-way transmission of disease. 3 Isolation measures: Establish contact, air and droplet isolation measures according to the transmission route. The focus is on hand washing and the timing of hand washing. To sum up a sentence: when there is no evidence that the patient has an infectious disease, are treated as patients with infectious diseases. For example, the pregnant woman in the report, before the results are available, we should assume that she (the body fluids, blood) are infectious, thus taking strict isolation protection measures to avoid infection. Occupational exposure: It is a situation where a person is exposed to a risk factor due to an occupational relationship, thus potentially damaging health or endangering life, and is called occupational exposure. Occupational exposure of medical personnel refers to a type of occupational exposure in which medical personnel are exposed to toxic or harmful substances or infectious disease pathogens in the process of engaging in treatment and care activities, thereby damaging health or endangering life. Medical personnel occupational exposure is divided into infectious occupational exposure, radiological occupational exposure, chemical (such as disinfectants, certain chemicals) occupational exposure, and other occupational exposure.
