A piece of foam with an open cell structure is introduced into the wound and a wound drain is placed with lateral perforations on top. The entire area is covered with a transparent adhesive membrane, which is firmly fixed to healthy skin around the wound margin. When the exposed end of the drain tube is connected to a vacuum source, fluid is withdrawn from the wound through the foam into a reservoir for later disposal.It is necessary to cover the wound bed with a soft polyvinyl alcohol foam sponge, a non-stick oil-emulsion dressing (for exame, Johnson and Johnson), a contact layer (such as Mepitel), a thin layer of amorphous hydrogel (can be Intrasite Gel), or a calcium alginate (such as Sorbsan) before application of the gray sponge. Avoid the use of Vaseline, which is too oily and can alter the adhesion of the VAC cloth.

VARVARA [1.3K]

Molecules of dna that in humans are organized into twenty-three (23) complementary pairs are called the genome.

The genome is the entire set of DNA instructions found in a cell. In humans, the genome consists of 23 pairs of chromosomes located in the cell’s nucleus, as well as a small chromosome in the cell’s mitochondria. A genome contains all the information needed for an individual to develop and function.

                    DNA is the information molecule for all living organisms. All of the DNA of an organism is called its genome. Some genomes are incredibly small, such as those found in viruses and bacteria, whereas other genomes can be almost unexplainably large, such as found in some plants.
