1.5 statistical methods to enter the relevant data into the statistical software SPSS19.0.
Analysis, qualitative data adoption rate indicates that the line test, P 0.05 for the difference has.
statistical significance.
2 Results
2.1 visual observation observation group visual inspection pass rate of 98.83 (593/
600), significantly higher than the control group 87.33% (524/600), the difference was statistically significant.
Righteousness (
=61．62，P<0．05)。
2.2 hemoglobin method
The qualified rate of hemoglobin detection in the observation group was 96.0%
(576/600), compared with 95.33% (572/600) in the control group, the difference was not statistically significant.
meaning (P>0.05).
3 Discussions
Surgical instruments and instruments are important auxiliary tools for the diagnosis and treatment of diseases, but their table
The surface will remain blood stains, pus, bacteria, etc. during use, and will be formed on the surface of microorganisms.
Into a layer of protective film, reduce the disinfection and sterilization factors on bacteria and other killing effect, reduce the clear.
Clean pass rate. Hemostatic forceps is one of the commonly used surgical instruments to rescue patients with massive hemorrhage,
It has many types and different shapes, and its main function is to clamp blood vessels and carry out physical hemostasis,
The hemostatic effect is obvious and rapid. Studies have shown that blood is important for iatrogenic infections
Pathway, if the hemostatic forceps disinfection is not qualified, may induce infection or rejection, and then Wei.
Threatens the safety of the patient's life. Therefore, disinfection supply center must improve the reuse
The success rate of disinfection of the instrument reduces the amount of bacterial residues on the surface of the instrument.
It is pointed out in the literature that choosing the right cleaning fluid to clean surgical instruments is to improve the quality of cleaning.
otherwise, it will not only reduce the cleaning pass rate, but also may affect the instrument.
The use. Enzyme-containing cleaning agent contains a large amount of protease, lipase, etc., in l5 ~
Under the condition of 30 ℃ water temperature and neutral pH value, the blood stains on the surface of the instrument can be effectively removed,
Pollutants, etc., to improve cleanliness. Some scholars take enzyme-containing cleaning agents and non-enzyme-containing cleaning agents
Cleaning of surgical instruments, it was found that the cleaning cleanliness of the enzyme-containing cleaning agent was relatively high]. Near
Over the years, enzyme-containing cleaning agents have been gradually applied to the cleaning of surgical instruments, but the cleaning agents
The cleaning effect is also significantly different. This article takes 1200 pieces of hemostatic forceps
As the research object, the control group take multi enzyme cleaning agent cleaning, the observation group take alkaline
Enzyme-containing cleaning agent cleaning, found that the two groups of hemoglobin method detection pass rate difference is not statistical.
meaning (P>0.05). The results show that the multi-enzyme cleaning solution and alkaline enzyme-containing cleaning
Liquid can effectively remove the instrument surface protein, blood, etc. Studies have shown that enzymes
Cleaning on the decomposition of organic matter is also relatively strong, can be used for uneven, serious
J, consistent with the results of this study.
In this study, the visual inspection pass rate of the observation group was 98.83%, significantly higher than
The control group was 87.33%, the difference was statistically significant (P<0.05). The result table
The effect of alkaline enzyme-containing cleaning agent on the surface brightness of the instrument is relatively small. Research
It is pointed out that alkaline enzyme-containing cleaning agents have strong decontamination ability and are non-corrosive to surgical instruments.
Corrosion, after cleaning will not affect its surface luminosity and use function, can extend the use
With time. Some scholars compare and analyze neutral and alkaline enzyme-containing cleaning fluids in instrument cleaning.
In the application of washing, it was found that the corrosive effect of alkaline enzyme-containing cleaning fluid on the instrument was relatively.
smaller, consistent with the results of this study. Therefore, the disinfection supply center cleaning surgery specialist.
When using instruments and metal instruments, you can try to choose alkaline enzyme-containing cleaning agents, not only can be
High cleaning pass rate, but also can reduce the damage to the instrument.

Soak in the enzyme solution; ② During the cleaning solution configuration, the water temperature should be controlled at 25~30 ℃
,
Avoid too high water temperature to reduce enzyme activity; ③ If the enzyme-containing cleaning solution is configured for more than 8h, it should be renewed.
Configuration to avoid new organic infection during cleaning; ④ Take the instrument to soak, should be
The joints of the instrument and the tooth groove of the clamp are all opened to reduce the residual rate of organic substances].
In summary, the alkaline enzyme-containing cleaning agent has a strong decontamination capacity, less corrosive to the instrument.
The characteristics of the cleaning of instruments can improve the cleaning pass rate and reduce the medical source sex appeal.
The probability of dyeing is of high application value in improving the quality of hospital diagnosis and treatment.
