clinical laboratory skills counseling: steps of dressing change for various types of wounds

steps of dressing change for various types of wounds:

operators should wash their hands and wear hats and masks before dressing change.

(1) Shallow, flat and clean wound: wipe the wound with sterile saline cotton ball and cover it with vaseline gauze.

(2) Wound of granulation overgrowth: Normal granulation is bright red, dense, clean and flat. If it is found that the granulation is reddish or gloomy in color, the surface is coarse and granular, and the edema is brighter than the wound edge, it can be cut off, and then the saline cotton ball is wiped dry and pressed to stop bleeding. It can also be cauterized with 1% ~ 2% silver nitrate solution, and then wiped with isotonic saline. If granulation is slightly edematous. 3% ~ 5% hypertonic saline can be used for wet compress.

(3) wounds with more pus or secretions: such wounds should be wet-compressed with disinfectant solution to reduce pus or secretions. The medicine for wet dressing depends on the wound surface, such as L: 5 furacilin or bleaching powder boric acid solution. Change dressing 2 ~ 4 times a day, and at the same time, sensitive antibiotics can be selected according to different strains cultured on the wound. For wounds with deep abscess cavity or sinus tract, normal saline or various exudates with sterilization and putrefaction can be used for washing, and drainage materials should be properly placed in the wounds for collection and sorting.

(4) Chronic intractable ulcer: This kind of wound surface will fester and not heal for a long time due to poor local circulation, malnutrition or improper early treatment of cut surface or specific infection. When dealing with this kind of wound, first find out the reason and improve the general condition. Local use of Shengjisan and penicillin can kill the bacteria in the wound and promote the growth of granulation.
