Suzhou A hospital once admitted a 4-year-old girl. The end section of the middle finger of the girl's left hand was black and had been necrotic for many days. She needed amputation surgery to prevent the condition from worsening further. What is surprising is that the girl's fingers were necrotic, but after being injured, she put a small bandaid on it. In order to prevent the cloth strip from loosening and falling off, the parents wrapped it with cowhide bands on the cloth strip. Due to improper handling, blood circulation in the fingers is not smooth and eventually necrotic.
Band-Aid is the most commonly used surgical medicine in people's lives, commonly known as "hemostatic plaster". The Band-Aid is mainly composed of flat cloth, tape and water-absorbing pad, which has the effects of stopping bleeding and protecting wounds.
Notes on correct use of bandaids
The wound length should not exceed the width of the bandaid. Suitable for cutting with neat, clean, shallow incisions, small and small without stitching. Before use, the wound must be disinfected and carefully checked for any dirt left in the wound. If there is unclean or foreign matter, the wound must be cleaned and dried with normal saline. When applying a bandaid with
, pressurize the wound slightly to play a role in compressing and stopping bleeding. Pay attention to the protection of wounds, do not move locally in the wound, avoid water, and avoid contamination. Do not squeeze the wound with your hands frequently, and prevent it from squeezing and hitting the wound to avoid cracking.
After using the bandaid, you should also pay attention to the changes in the wound and replace it regularly to prevent the wound from being infected and suppurated. Some people may think that a bandaid can be applied for several days, but in fact, it cannot be applied for more than 12 hours. Band-Aids should be changed frequently. If the wound pain worsens or secretions seep out, you should open and check in time; if the wound is found to have redness, swelling, effusion and other infections, you should stop using Band-Aids and go to the hospital for diagnosis and treatment in time.
What wounds can't be used to use Bandai
Small and deep wounds: If the soles of the foot are damaged by a nail, if they are not completely debride, it will be conducive to the breeding of anaerobic bacteria , causing infection or tetanus .
Infected wounds: such as boils, pustules.
Animal bites: This wound needs to be repeatedly rinsed with soapy water, and then the wound is exposed.
Burn . Scald wounds: This kind of wound is generally larger and is not suitable for using band-aids. It may cause or aggravate its infection when using band-aids.
Slight epidermal abrasion: wipe it with medical alcohol or iodine and expose the wound.
The wound is unclean or there are foreign objects: using bandages will aggravate the infection or cause the residue of foreign objects.
Special attention:
Band-Aids should not be wrapped too tightly when used, especially fingers and toes. Wrap them too tightly is conducive to the breeding of anaerobic bacteria and will increase the probability of infection and tetanus; do not bandage them in a circular shape. The arteries of the fingers and toes are on both sides. If they are wrapped too tightly, it will cause blood circulation to be unclear. In mild cases, the wounds may swell, and in severe cases, it may lead to necrosis at the ends of the fingers (toes) and amputation.
was injured, so we quickly put the bandaid on the wound to prevent "wind" - everyone mistakenly believed that tetanus was caused by "wind". It should be noted that tetanus is a bacteria - Clostridium tetanus , not "wind".
