Gauze is an excellent material for healing a wound.
The term 4×4 gauze is used to describe a pre-measured square of gauze fabric, folded once in half, that surgeons and other medical professionals use during surgery or to heal wounds. Known for its open weave and airy quality, gauze is an ideal wrapping for burns and skin lacerations. The 4×4 gauze size is 4 inches wide by 4 inches long (10.16 cm by 10.16 cm) once folded and can be sold in bulk or in individual sterilized envelopes.
Squares of 4×4 gauze are often applied to a wound and then secured with a wrap.
Gauze is an excellent material for healing a wound because it allows moisture to escape, but it is also absorbent and absorbs excess fluid from the wound. It is also non-adherent, so it can be used as a primary or secondary dressing. During medical procedures, 4×4 gauze is also often used by doctors to absorb blood and other fluids that penetrate the surface of the skin.
Gauze can be used to cover a wound on someone’s hands.
Usually woven from cotton and other fibers, gauze can also be made from synthetic fibers that are pressed together to create a solid piece of fabric. Gauze can be purchased in a variety of ways: on a roll, in ribbons or strips, or in pre-cut sections like 4×4 gauze. When the gauze is pre-cut, it is usually easier for the surgeon’s gloved hands to grasp and maneuver in a particular way.
Gauze pads are typically pre-cut and individually wrapped to ensure the dressings remain sterile.
The gauze may be sterile or non-sterile. When sterile, 4×4 gauze is usually packaged as a pair of cloths inside a plastic or paper cover to keep it clean. Sterile gauze is more expensive than non-sterile, costing three to four times as much. Non-sterile gauze is usually packaged and purchased in bulk as it does not need to be kept sterile.
Sterile gauze can be used to prevent infections in burn victims.
The thickness of medical grade gauze can vary and is measured in terms of application. In the textile industry, folding is the process of taking two or more strands of fabric and intertwining them. When six strands are used for the weft, for example, it is called 6 layers. The thickness of medical grade 4×4 gauze is usually 8 or 12 layers, with thicker gauze being more expensive.
The gauze can be pre-treated with any amount of substances. Antibiotic ointments are often pre-applied to medical gauze, as are antiseptics. This pretreatment is convenient as many wounds require multiple dressings to be applied and reapplied during the healing process.
Dressings can be wet or dry. Dry gauze dressings help heal wounds by eliminating excess dry seepage. Some doctors prefer a moist environment for wound healing and may use moist gauze or pre-treated gauze.
