Alcohol balls do not stay immersed in the wound for long periods of time, and the specifics will depend on the condition in question. Alcohol balls are usually made from cotton balls soaked in alcohol. When the alcohol contacts the skin, it can sterilize the skin around the wound, but it can’t directly contact the wound for a long time, because the higher concentration of alcohol will cause more damage to the wound, which may cause severe pain and even delay the wound healing, so the alcohol ball can’t be soaked for a long time in the wound. It is recommended that patients should use iodophor under the guidance of the doctor to disinfect the skin when trauma occurs, and when the situation is serious, they should also go to the hospital for debridement, suturing, regular dressing changes, removal of stitches and other treatments. It is recommended that patients should keep the wound clean and hygienic during the recovery process, and do not touch water, which will help the wound to heal. If there is any discomfort, consult a doctor promptly.
