When you have been hurt, nobody is likely to think about the possibility of an infection developing in the wound. It is particularly difficult to keep track of children, who are running, jumping, and regularly suffering traumas. And sometimes, afraid of parents getting angry, the scratched knee is hidden until it is too late and an infection has developed...
Besides failing to attend to wounds in a timely manner, the risk of wound infections developing is higher in some groups of people due to various comorbidities. These are, for instance, diabetes patients, obese people, smokers, patients, who are often hospitalised due to an illness, patients with weak immunity (immunodeficiency, HIV infection).
Wound becomes infected if microbes that are not found on the skin of healthy people enter the wound and normal microbes have excessively proliferated. Infections are most commonly caused by streptococci, staphylococci, intestinal bacteria, among many other pathogens. Microbes replicate in the wound and release various chemicals that aggravate the inflammation, immune system cells end up in the wound, and the primary tissue task is now battling the infection instead of healing and tissue regeneration; this is why it is important to care for the wound correctly.
If the infection has affected a wound after a surgery, you must promptly visit your doctor, who will prescribe antibacterial drugs and, if necessary, treat the wound surgically.
You should be particularly careful if the wound has been inflicted by a sharp object, by cutting through the skin, and has been in contact with black soil, saliva or animal excrements; the doctor will decide whether tetanus or rabies prophylaxis is needed.
If a surface wound has become infected (after scratches, bruises, burns, abrasions), assess your health condition critically. If there are signs of a systemic infection (elevated body temperature, shivering, nausea, pain beyond the wound), visit a doctor, who will prescribe antibacterial medicines. If there are signs of a local infection only (redness, swelling, pain, elevated temperature around the wound), then the infection can be contained and sopped, given proper treatment.
Wash hands before treating the wound, and, if possible, wear disposable gloves to avoid other microorganisms entering the wound. The wound can be rinsed with a physiological solution, but Furasol is recommended for a more successful effect — it is a powder that is dissolved in a glass of hot boiled water, and this solution (after cooling it) is used to treat the wound 1–2 times per day. Unlike alcohol containing solutions, Furasol is not irritating, therefore it is recommended in the treatment of fresh and healing wounds alike. The wound should be treated 1–2 per day, however if this treatment has not improved the wound condition, you should visit a doctor, who will choose a suitable therapeutic remedy.
