In outpatient clinics and wards, people often come to see the doctor worried about having rabies because they were accidentally bitten by their own dog or by a neighbor’s dog, and because they did not treat the wound in time and recently developed some symptoms. In some cases, because the wounds were not treated correctly and promptly, and the rabies vaccine was not administered, the manifestations of fear of water and wind and tight throat appeared after the incubation period, and no more than 6 days really died because they had rabies, which had to draw our attention. So, after being bitten by a dog, how should you properly treat the wound and carry out preventive vaccination measures? First of all, after being bitten by a dog, immediately wash the wound repeatedly with soap and water, disinfectant or water alone for no less than 15 minutes, and when the wound is deep, repeatedly flush it with syringe infusion for at least 30 minutes; then disinfect it repeatedly with alcohol and finally apply iodine; try to require no hemostasis, no dressing, and no suturing of the wound. Passive immunization is then performed according to the grading and degree of exposure, i.e.: local infiltration injection using human anti-rabies immunoglobulin (HRIG) 20 IU/kg or equine anti-rabies immune serum 40 IU/kg (after negative skin test) at the base and around the wound; simultaneous arm intramuscular injection is done at the same dose. Antibacterial drugs were used when necessary; tetanus antitoxin was also used when the wound was deep. Finally, take active immunization measures, i.e., inject rabies vaccine, which should be given as early as possible after the bite: 1. 5 injections for general patients, one each on days 0, 3, 7, 14, and 30; each intramuscular injection of 2 ml. 2. 10 injections for patients with severe bites, one injection daily for the first 6 days, and one injection each on days 10, 14, 30, and 90. The dosage of injection is the same as before.3. For re-bites within 1 year, one vaccination each on 0 and 3 days; for re-bites within 1 to 3 years, one vaccination each on 0, 3 and 7 days, and for more than 3 years, a new vaccination. The dosage of injection remains the same.
