Potassium permanganate solution (Povidone) in which ethacridine lactate and cod liver oil gauze are used for infection, so methyl violet solution has been rarely used in clinical dressing changes. Wash and wet the wound. It has nutrition and promotes granulation, and is against gram-positive cocci. The basic principle of surgical dressing is aseptic, especially streptococcus has a strong effect, and a small number of gram-negative wounds with few secretions have a strong killing effect , 0.02% potassium permanganate solution decomposes slowly to release oxygen, but has a long-lasting effect, with cleaning, deodorizing and antiseptic effects. It is used for washing rotting, foul-smelling, and infected wounds, especially for suspiciously infected, anal and perineal wounds.
In clinical practice, a 1:5 000 solution is commonly used for wet compresses. 0.1% Revenul (ethacridine lactate) and 0.02% nitrofurazone solution, both have an effect. The nitrofurazone has a broad spectrum, and it also has an effect on a variety of Gram-positive and negative bacteria. 2%~4% methyl violet solution (gentian violet), also known as "purple syrup", has astringent effects. It is used for superficial skin or mucous membrane ulcers, and promotes the healing of scabs, but it is not suitable for superficial wounds with more secretions. Povidone In recent years, studies have claimed that methyl violet solution can change the genetic material of animals and cause cancer. Although relevant evidence has not been seen in humans, the potential carcinogenicity of methyl violet solution still deserves our vigilance. Oil gauze, oil gauze can drain, protect the wound, prevent the dressing from drying out, and prolong the dressing time. It can be replaced every 2 to 3 days.
The most commonly used is vaseline gauze, which is used for fresh wounds to protect the epithelium; for epithelial growth and other functions, it is used for slow-healing wounds. (Povidone) However, it must be clear that aseptic technique and hand hygiene practices throughout the entire dressing process. And there are quite a few more complicated wounds that require doctors to make proper treatment after careful observation to promote wound healing. Therefore, we emphasize that surgical dressing changes must be performed by trained medical personnel. How does the culture medium affect the key quality attributes of antibodies? Recombinant protein products can be mass-produced for effective treatments, such as growth factors, blood coagulation products, thrombolytics, vaccines and monoclonal antibodies (mAb), which have an impact on human health. Among them, monoclonal antibodies (mAbs) contain large-molecule multi-domain proteins, which require complex analysis equipment to perform correct protein folding, assembly and post-translational modification and other indicators.
