Amoxicillin powder should not be directly sprinkled on the wound, which is not only less effective, but also easy to produce drug resistance, affect wound healing and wound treatment, and may also cause infection. If you want to achieve the purpose of sterilization, it is recommended to use iodophor, medical alcohol, etc., the disinfection effect is better and will not produce many adverse consequences. The harm of amoxicillin powder directly scattered on the wound mainly includes: 1, produce drug resistance: amoxicillin is usually used for oral treatment, if often use amoxicillin powder scattered on the wound treatment, may make the body produce drug resistance, that is, when the body occurs bacterial infection, there may be the use of antibiotic treatment is not effective; 2, affect the healing: amoxicillin powder scattered on the wound can be mixed with wound exudate, blood, resulting in trauma. It can be mixed with wound exudate and blood, causing contamination of the wound surface, which is not conducive to wound recovery and affects healing. In addition, the high concentration of amoxicillin powder may affect the growth of granulation tissue when scattered directly on the wound, thus affecting the healing of the wound; 3. Affecting wound treatment: Scattering amoxicillin powder directly on the wound will obscure the wound, which will easily cause misdiagnosis and omission if going to the hospital for follow-up treatment, and is also not conducive to debridement treatment; 4. Using amoxicillin powder to sprinkle the wound to eliminate inflammation may lead to the wound being easily invaded by pathogenic bacteria and infection. Amoxicillin is an orally administered drug, and it is usually only absorbed in the digestive tract to achieve the purpose of sterilization and anti-inflammation and control of infection. Amoxicillin has a narrow antibacterial spectrum and has a limited bactericidal effect on pathogenic bacteria in traumatic wounds, which is not as effective as iodophor or alcohol.
