Yes it can but it must be kept very clean.
Yes but there is a great chance that it would get infected and take twice as long to heal; then there is a possibility that they would lose too much blood. What is important for healing is that the wound surfaces are clean and that they are brought together so the tissues will rejoin. There are other means of bringing and holding cut tissue surfaces together, such as skin adhesives or tight dressings. Deep wounds are another matter and may require multiple layers of stitches or bindings.
Sugar in an open wound will prevent the growth of bacteria, allowing the wound to heal more quickly. Sugar in an open wound will prevent the growth of bacteria, thus preventing infection and allowing the wound to heal more quickly. It is particularly helpful for wounds that are difficult/impossible to close surgically.
I would use Neosporin
This question is very vague. What kind of open wound? Any open wound that needs stitching means attending hospital. If stitches are not needed, then normal first-aid will do: Wash the wound with an antiseptic solution, cover with a sterile pad, bandage or use a plaster. Change the covering in a day or two, until healed.
That is all relative. If they are in an extra day or two, it doesn't usually hurt anything. Leaving them in for several days too long can cause some problems though. This can include skin irritation, infection, and increased scarring.
Granulation tissue is tissue with good blood circulation and adequate blood supply is needed for a wound to heal.
put on some lavender oil. essential oils are good for anything that life throws at you. it will heal the wound and infection (if there is one) and leave no traces of a scar.
A wound is one thing that is always unique; no two wounds are ever exactly the same in length or depth. We have all had a minor cut, such as a paper cut. These are superficial wounds, because they only affect the first layer of skin. The edges of a superficial wound are usually straight, and the edges naturally stay close together. A deeper superficial wound may only need a "butterfly strip" to keep the edges together so it can heal. However, other wounds are deeper. We might call the wound a "gash", because the edges are open. We can often see into the wound to the tissues under the skin. A gash always needs stitches. The number of stitches depends on how deep the gash is; how long the wound is; and whether it is a straight line wound or a jagged edge wound. Stitches begin inside a deeper wound, using special "thread" that the body will dissolve over time as the wound heals. The stitches are used in layers, from the inside out (sort of like pressing the bottom of a almost empty tube, until you get to the top). The deepest part may only need 1 stitch, but it could need many stitches. The next layer often needs more stitches along the INNER length of the wound. On MOST wounds, there is one inner layer and one skin layer, but there could be more layers used on the inside, depending on the depth of the wound. As one example, I stepped on the lid of a can from cat food. The metal is very sharp, but circular and easily bent (so it causes ragged wound edges inside). So the metal would make a shorter cut inside than it would at the skin-- the skin wound would be much longer. The E.R. doctor put in two stitches at the deepest part; then three at the next layer; and 5 on top of that because the metal had bent as I stepped on it, making the wound more jagged inside. He closed the skin layer with 7 stitches. But one stitch at the end of the wound made the skin pucker; it needed removed and they put two stitches there instead. Every wound is different. The number of stitches needed cannot be known until after a doctor assesses the wound. The doctor will use only enough stitches to keep the edges, inside and out, close together so the body will begin to fill in the wound with granulation cells that repair the wound. Not all wounds leave scars, but some do.
After a careful examination and evaluation, the wound will be cleaned.The area will then be numbed with a local anesthetic. This will allow a deeper examination of the wound as well as repair without any further discomfort. You may feel pressure, but no pain.If the wound requires stitches, it will be cleansed with an antiseptic solution, and sterile towels or drapes placed over the area. The doctor will wear sterile gloves and put in the stitches to bring the wound edges together.Once this has been accomplished, the area will be washed off once again and a sterile bandage applied.
It must be cleaned out and stitched by a doctor. It would have to be bandage for a short period of time. Stitches would come out in a week or two depending on the wound.
You need to seek help from a doctor, otherwise you may suffer very nasty infections or diseases from your open wound. You can wrap a bandage tightly around your arm and hope it closes on its own.
The Phoenix's healing tears will only work on injuries. Dumbledore was hit with the killing curse which stopped his heart but left no wound.
