Medical scalpel is a tool that is often used in hospitals to perform operations on patients. Disinfection of these tools is the key to ensuring that patients do not experience local infections and complications.
The medical scalpel blades were randomly sterilized by three methods, that is, high-pressure steam sterilization, boiling disinfection, and soaking disinfection. Thirty samples were taken for each disinfection method, and the total of the three groups was 90 times. Before disinfection, ten cases were drawn from each group to culture the bacteria.
Sampling before disinfection
When performing the operation, wear sterile gloves and use sterile saline to rinse the surgical blade and suture needle. The rinsed liquid is poured into the culture tube for bacterial culture. Before and after this, the mouth of the sterile test tube must be cleaned. Burn with an alcohol burner.
Wash the surgical blades first, use high-pressure disinfection, boiling disinfection, soaking disinfection for 30 minutes, perform aseptic operation, put on sterile gloves, continue to rinse twice with sterile saline tablets, and then pour Then use 2 milliliters of sterile saline to clean the surgical blade and the suture needle, and pour the cleaning solution into the test tube to cultivate the bacterial chamber.
It was found that among the 30 cases of bacterial culture before disinfection, 26 cases were bacterial growth, 86% were positive, and 70% of them were Gram-negative bacteria. After disinfection, there was a significant decline. Moreover, all three disinfection methods have certain effects, and the effect of boiling disinfection is very obvious, but it is best to use disposable medical surgical blades, and throw them away directly after use.
