Myth 1: Wash the wound with alcohol and hydrogen peroxide.
Correct method: Wash with iodophor or active iodine, complex iodine and normal saline.
Guo Shuzhong, chief physician of plastic surgery in Xijing Hospital and member of China Plastic Surgery Society, said that alcohol and hydrogen peroxide have a strong * * * effect on normal tissues. Alcohol will condense the protein of cells, which is harmful to bacteria and normal tissues; Hydrogen peroxide, because of its strong oxidation, may cause chemical burning to tissues, which is more likely to cause damage to children's delicate skin.
The correct method of wound cleaning should use iodophor, active iodine, complex iodine and other disinfectants with mild properties and little toxicity to tissues, combined with normal saline.
Myth 2: Wounds are afraid of the wind and cannot be exposed to the outside.
The correct method: "airing" the wound can drain the exudate in time.
This statement mostly comes from a misunderstanding of tetanus. We often talk about "tetanus", which is a specific type of infection caused by tetanus bacilli invading the human body through skin or mucosal wounds, growing and reproducing in an anoxic environment and producing toxins. It is not the "fear of seeing the wind" that many people understand.
Shu, head of the second group of craniofacial plastic surgery in Xijing Hospital, said that for some wounds, the coverage of gauze and other dressings can really isolate the wounds from the outside world and play a role in blocking bacteria. However, for abrasions or some wounds with more exudates, the method of "air drying" can drain exudates in time, keep the wound dry and be beneficial to wound healing. Whether the wound needs dressing or exposure depends on the doctor.
Myth 3: Applying soy sauce and toothpaste to the scalded area is beneficial to wound healing.
Correct method: rinse with cold water 10 minute.
The child was accidentally burned, and many parents' first reaction was to apply toothpaste and soy sauce. Wound. Xiao Houan, director of the Department of Burn and Plastic Surgery of the Ninth Hospital of Xi City, said that this would only cause * * * wounds, which is very unfavorable for wound healing. Because the hot air of the wound is covered by toothpaste and other substances, the hot air can only spread deep into the subcutaneous tissue, causing deeper burns.
Some parents will use ice to cold compress the burned area, which is also not desirable. Ice cubes can cause secondary damage to injured skin. The best way to treat burns is to rinse with cold water for 10 minutes, or soak the affected area with cold water to cool down the hot air, so as to relieve the pain and reduce the degree of injury.
Myth 4: sewing is to leave a scar, not sewing is to leave a scar.
The correct method: timely debridement and regular dressing change.
For most wounds, only suture can realize the accurate combination of tissues and provide good conditions for wound healing. If you don't do suture treatment, only rely on the contraction of the wound itself to scab, which will inevitably leave obvious scars. There is only a small part of trauma, because the wound is shallow, there is no obvious pollution, and the tissue is well arranged, so suture treatment will not be considered. Even so, timely and thorough debridement and regular dressing change are necessary.
Shu said that in the past, many wounds were stitched with thick needles and thick threads, which eventually led to a scar even larger than the wound scar, forming an ugly scar like a centipede's foot. What we are using now is cosmetic plastic stitching technology, and the thickness of stitching is equivalent to the thickness of hair. Except for some patients with particularly sensitive constitution, most patients will not have similar problems.
Myth 5: Itching is a good thing, indicating that the wound grows well.
Correct method: It may also be a local rash or drug allergy, so you should see a doctor in time.
Under normal circumstances, in the process of wound healing, local itching will occur because of the gradual growth of nerve endings. On the other hand, improper dressings, such as contaminated gauze and other dressings, can cause local rash and drug allergy, and can also lead to itching of wounds. So when you feel itchy, you'd better tell the doctor, and the doctor will judge whether it is wound healing or other reasons.
Myth 6: The wound should be kept dry and will heal soon after scabbing.
Correct method: It is better to use dressing to keep it properly moist.
Many people think that the wound should be kept dry and the scab will heal soon. In fact, this understanding is wrong. Because when the skin surface cells migrate and proliferate, if they encounter scab, the cortical cells are difficult to move and the wound healing time becomes longer. However, in a moderately humid environment, the cell regeneration ability and swimming speed of the wound are faster. Therefore, the wound should be bandaged to keep it properly moist. It is recognized by medical circles that the good speed of wet wound is about 1.5 times faster than that of dry wound.
Myth 7: The wound is infected by running water.
Correct method: the wound is red, swollen and painful, and the exudate is thick and turbid, which may be an infection.
The wound may have normal exudation and secretion during the healing process, and the most common one is light yellow clear liquid, which is mostly exudation from serum or normal tissues and does not need special treatment. Once the wound is red, swollen and painful, there is a thick and turbid exudate, which is probably an infection. Go to the hospital as soon as possible.
