0 Introduction
In order to prevent and control the iatrogenic infection caused by endoscopy, the development of digestive endoscopy
New methods of disinfection and cleaning, improve the quality of endoscopic care, extend the service life of endoscopes, etc.
A series of problems are the focus and hot spot of the discussion and development of endoscopic disinfection and cleaning work. And
At present, the disinfection and cleaning methods of digestive endoscopes, such as glutaraldehyde immersion method, are easy to make internal
The mirror shows yellowing and roughening, shortening the service life of the mirror, and cleaning is not thorough enough; and
In-depth exploration and innovative development of disinfection and cleaning methods of digestive endoscopes is a very
The key problem is how to better develop clean, reliable and safe disinfection methods,
Ensuring the quality of disinfection and cleaning of digestive endoscopes and prolonging their service life is currently a medical inquiry.
One of the more lacking links in the development of limitations, while this area is also
The important direction and goal of exploration and development. In view of this series of problems, to explore the new
Disinfection cleaning method is imminent. For digestive endoscopes in the disinfection and cleaning process may
There are organic solution residues, high concentrations of disinfectants exist safety hazards, disinfection process.
There are problems such as damage to the endoscope, and this paper compares glutaraldehyde with phthalaldehyde.
The application of two methods in the disinfection and cleaning of digestive endoscopes was analyzed.
1 Data and methods
1.1 general information. Statistical analysis from January 2015 to December 2015 in our hospital
80 endoscopes after poisoning and 40 endoscopes in the control group were soaked in 2% glutaraldehyde.
bubble disinfection method for disinfection; and for the experimental group of 40 pieces of digestive endoscopy,
Then take 2% concentration of o-phthalaldehyde for soaking disinfection. control group and experimental group
The digestive endoscopy remained consistent in the length of immersion, and the later flushing treatment was the same;
At the same time, the two groups of endoscopes in the specifications, models, pollution and other aspects have no significant difference,
with statistical significance (P>0.05）。
1.2 methods. The inner surface of the digestive endoscope is used as the sampling site for detection, and the corresponding middle
and buffer collection for inspection, detection of pathogenic bacteria in the inspection liquid, and statistical phase
should result.
1.3 statistical methods. Combined with the Ministry of Health "endoscopic cleaning and disinfection technical operation specification"
standard, using SPSS to count the data to an independenttparty inspection for analysis;
a=0.05。
2 Results
2.1 disinfection effect. The number of pathogenic bacteria on the inner surface of the endoscope in the control group was
(0.97±0.74)cfu/cm3; the number of pathogenic colonies on the inner surface of the experimental group was
(0.76±0.83)cfu/cm3; the difference between the two groups was not statistically significant.
2.2 cleanliness. The total number of colonies counted on the inner surface of the endoscopes in the control group was
(1.61±0.65)cfu/cm3; the total count of colonies on the inner surface of the experimental group was
(1.16±0.63)cfu/cm3; the difference between the two groups was not statistically significant.
3 Conclusions
Digestive endoscopy, as a widely used invasive medical diagnosis and treatment equipment,
Due to its own structure, material and cleaning requirements and other reasons, its disinfection and cleaning
Washing is an important and complicated work. If endoscope disinfection and cleaning are not up to standard,
Will seriously affect the patient's treatment effect, and even bring serious consequences, can be described as the relationship
Significant. Through the clinical exploration and analysis of this paper, as well as the effect of endoscopic surface disinfection.
And the clean degree of statistical analysis results show that, relative to the "disinfection technical specifications" in the objective.
Before the use of glutaraldehyde disinfection method, take o-phthalaldehyde immersion disinfection method,
The total number of colonies remaining on the endoscopic surface and the number of pathogenic bacteria were significantly less than those in the control group.
Glutaraldehyde disinfection method, disinfection effect is obvious. Investigate its reason, this is because o-benzene two
Formaldehyde immersion disinfection [1-3] is through the combination of biological cell wall and cell membrane, forming a
Barrier, prevent tissue material exchange, inhibit the physiological function of bacteria and achieve disinfection and sterilization
The role. Comparative analysis of the results of the experimental group and the control group shows that the use of two benzene
aldehyde immersion disinfection in the same time within the disinfection and sterilization effect is better, according to other scholars
The results of the study [4], this study should be confirmed by the use of phthalaldehyde on digestive endoscopy.
Disinfection, can effectively solve the clinical practice of endoscopic disinfection in the presence of disinfectant.
Strong corrosion, the use of the endoscope safety and service life has a greater impact.
And in the process of disinfection may have some residual organic material problems, at the same time effective
Shorten the time of contact between medical staff and disinfectants (to achieve the same disinfection standard.
The time required for disinfection with phthalates is shorter), which improves the relationship with endoscopes.
Safety and health protection of medical staff with frequent contact. At the same time, due to the use of glutaraldehyde
Disinfection, the need to face the easy to make the endoscope show yellow, rough, shorten the endoscope make.
At the same time, the toxicity of glutaraldehyde itself makes the secondary contamination of the endoscope.
The problem is difficult to prevent, and the use of o-phthalaldehyde as a disinfectant to disinfect endoscopes.
Bubble disinfection treatment, can effectively reduce the damage of digestive endoscopy, prevent digestive endoscopy
(gastroscope, colonoscopy) secondary pollution, so that the life of digestive endoscopy can be extended,
This is great for both the patient's clinical surgery and the cost management of hospital instruments.
Benefits. The results of this clinical trial effectively prove that: compared to the current commonly used E.
Dialdehyde immersion disinfection method, using o-phthalaldehyde disinfection method in digestive endoscopy disinfection cleaning
Application practice can achieve more obvious results, the application prospect is broader, this
Exploration of Further Application Measures of Ortho-phthalaldehyde in Digestive Endoscope Disinfection and Cleaning
is important. Thus, the application of phthalaldehyde on digestive endoscopy
clinical effect is better, it is worth to promote the use and development in clinical practice and treatment.
