Surgical procedures do not cause HIV infection in the patient, because during surgical procedures, the corresponding medical equipment will do some operations on the patient’s wound, and these medical equipment will contact the patient’s blood, but these medical equipment must undergo strict sterility and disinfection treatment, so these instruments cannot contain any bacteria and HIV, so the person undergoing surgery will not be able to HIV infection. The principle of asepsis should be strictly enforced during surgery to avoid bacterial infections, and if the principle of asepsis is well enforced when the patient is undergoing surgery, then there is no way to contract pathogenic bacteria. It is possible to cause bacterial infection if the aseptic principle is not too well implemented, but it is unbelievable to cause HIV infection because there is no source of HIV in the surrounding environment. However, if the patient is an AIDS patient. There is a possibility of intraoperative contamination of mucous membranes by splashes of blood body fluids, sharp broken ends of bones, sharp instruments, etc., which pierce the skin of the surgeon and cause contamination, which needs to be blocked accordingly.
