An infected wound needs to be cured before you cover it over, or the infection will just spread and get worse.
Contaminate it prior to application.
Dressing a wound means to put a dressing on it. If you have a cut on your hand and you dress it you put some sort of packing or cream on the wound then you put a plaster or bandage on it this is called "dressing" a wound.
You want sterile dressing for open wounds. If you put a dirty dressing on an open wound, you are increasing the likelihood for infections and diseases. But if all that you have is a ripped t-shirt to put on a wound, that is definitely better than nothing at all.
It depends on the severity of the wound. If its a small surface wound wash it put antibiotic ointment in it and wrap it. If it becomes infected get it checked out. If it is a deep wound or it won't stop bleeding, go to the ER.
Swelling, redness at the site of the injury or surrounding area, streaks of red upward from the injury, an increase in the amount of pain any type of discharge from the wound, any foul odor, or if the area is just not healing .
well , u shouldnt.
Um......... bandages, I guess. But first you have to wash the wounds in cold water, then put a bandage or a cloth on the wound to cover it up and it won't get infected.
You can. Peroxide is probably not going to help a whole lot with the "spider bite" part, but it could help keep the wound from becoming infected.
Pencil wound
Quickly wash the wound with clean water and put dressing on it. If it's a very serious bite take the person to hospital to have it checked. Diseases can be spread if a person bites you.
The soldier got a wound from the battle
There shouldn't be a knot to tie. The treatment for an open chest wound is to put a piece of plastic over it and tape it down on the sides so that air cannot get in or out of the wound. There's nothing to tie down anywhere in that. You could be thinking of flail chest which has more to do with broken bones then an open chest wound. As an army medic I find your question soul crushingly confusing.
A first responder's priority is to control the bleeding, loss of blood means loss of Oxygen, Heat and Life Sustaining Fluids. =Don't worry too much about how the dressing looks / what dressing to use / what knot to use - when us Paramedics arive on site we aren't going to give you marks for neetness!=Note: Do not put any pressure onto a head wound in the attempt to stop the bleeding because if theres a skull fracture, you might push bony fragments straight into the brain!
