After this point in time, however, there is a theoretical concern of increased risks of infection if closed immediately. Thus some healthcare providers may delay closure while others may be willing to immediately close up to 24 hours after the injury. Using clean non-sterile gloves is equivalent to using sterile gloves during wound closure.If closure of a wound is decided upon a number of techniques can be used. These include bandages, a cyanoacrylate glue, staples, and sutures. Absorbable sutures have the benefit over non absorbable sutures of not requiring removal. They are often preferred in children. Buffering the pH of lidocaine makes the injection less painful. Adhesive glue and sutures have comparable cosmetic outcomes for minor lacerations <5 cm in adults and children. The use of adhesive glue involves considerably less time for the doctor and less pain for the person. The wound opens at a slightly higher rate but there is less redness. The risk for infections (1.1%) is the same for both. Adhesive glue should not be used in areas of high tension or repetitive movements, such as joints or the posterior trunk. Split-thickness skin grafting (STSG) is also a surgical technique that features rapid wound closure, multiple possible donor sites with minimal morbidity. Dressings
In the case of clean surgical wounds, there is no evidence that the use of topical antibiotics reduces infection rates in comparison with non-antibiotic ointment or no ointment at all. Antibiotic ointments can irritate the skin, slow healing, and greatly increase the risk of developing contact dermatitis and antibiotic resistance.
A type of amputation where the extremity is pulled off rather than cut off. When used in reference to skin avulsions, the term degloving is also sometimes used as a synonym. Puncture wounds – caused by an object puncturing the skin, such as a splinter, nail or needle. Penetration wounds – caused by an object such as a knife entering and coming out from the skin. Gunshot wounds – caused by a bullet or similar projectile driving into or through the body. There may be two wounds, one at the site of entry and one at the site of exit, generally referred to as a "through-and-through." Critical wounds- Including large burns that have been split. These wounds can cause serious hydroelectrolytic and metabolic alterations including fluid loss, electrolyte imbalances, and increased catabolism

Closed
Closed wounds have fewer categories, but are just as dangerous as open wounds:

Hematomas (or blood tumor) – caused by damage to a blood vessel that in turn causes blood to collect under the skin. Hematomas that originate from internal blood vessel pathology are petechiae, purpura, and ecchymosis. The different classifications are based on size. Hematomas that originate from an external source of trauma are contusions, also commonly called bruises. Crush injury – caused by a great or extreme amount of force applied over a long period of time. Presentation
Complications
Bacterial infection of wound can impede the healing process and lead to life-threatening complications.
