As a common means of medical examination
, gastroscopy plays an important role in the diagnosis of gastric diseases. However, because gastroscopy is an invasive examination, there is a certain risk of infection. Therefore, it is very important to prevent gastroscopy infection.
1. Overview
of gastroscopic infection
Gastroscopic infection refers to the infection of bacteria, viruses and other pathogens caused by improper operation, incomplete disinfection of instruments or pathogens in patients during gastroscopy. These pathogens may enter the patient’s body through gastroscopy, causing a series of digestive tract symptoms, even life-threatening in severe cases. Common pathogens of gastroscopy infection include Helicobacter pylori, Escherichia coli, hepatitis virus and so on.
2. Transmission route
of gastroscope infection The transmission routes
of gastroscope infection mainly include the following aspects:
Instrument transmission: The gastroscope and its accessories are in direct contact with the patient’s body during the examination. If the instrument is not thoroughly disinfected, the pathogen may be transmitted to the patient.
Cross infection between
patients: If the pathogen is present in the previous patient and the gastroscope and its accessories are not thoroughly disinfected after examination, the pathogen may be transmitted to the next patient.
Improper operation of
medical staff: In the process of gastroscopy, if medical staff do not follow the principle of aseptic operation, it may also lead to infection of patients.
3. Preventive measure
of gastroscopic infection. The key to
prevent gastroscope infection is to strengthen the disinfection of instruments, improve the operation level of medical staff, strengthen patient management and improve the hospital infection control system. Here are some specific preventive measure:
1. Strengthen instrument disinfection
Use of disposable instruments: For some replaceable gastroscope accessories, such as biopsy forceps, disposable instruments should be used as far as possible to reduce the risk of cross infection.
Strict disinfection procedures: The gastroscope and its accessories shall be cleaned, disinfected and sterilized in strict accordance with the Technical Operation Specification for Cleaning and Disinfection of Endoscopes. The cleaning process shall include preliminary cleaning, enzyme washing, rinsing, final rinsing and other steps; the disinfection process can adopt high temperature and high pressure steam sterilization or chemical disinfectant soaking and other methods; the sterilization process shall ensure that the surface and interior of the instrument are in a sterile state.
Regular monitoring of disinfection effect: The hospital should regularly monitor the disinfection effect of gastroscope and its accessories to ensure that the disinfection quality meets the national standards.
2. Improve the operation level
of medical staff
Strengthen training: The hospital should regularly train the medical staff in gastroscope operation skills and aseptic operation principles to improve their operation level and infection provention and control awareness.
Standardized operation: During gastroscopy, medical staff should strictly follow the principle of aseptic operation, such as wearing protective equipment such as gloves, masks and hats, to avoid direct contact with patients or instruments.
Timely reporting and handling: If the medical staff find that the patient has symptoms of infection or instrument contamination during the examination, they should report in time and take appropriate measures.
3. Strengthen patient management
Improve infectious disease screening: Before gastroscopy, patients should be screened for infectious diseases, such as hepatitis B, hepatitis C, AIDS, etc., so as to detect and deal with potential infections in time.
Inform patients of precautions: Medical staff should explain the process, risks and precautions of gastroscopy to patients in detail, and inform them of the hygienic requirements to be observed before and after the examination.
Reasonable arrangement of examination time: The hospital should reasonably arrange the gastroscopy time to avoid the excessive concentration of patients in order to reduce the risk of cross infection.
4. Improve the hospital’s sensory control system
.
Establish and improve the infection control system: The hospital should establish and improve the provention and control system of gastroscope infection, clarify the responsibilities and division of labor of each department, and ensure the smooth development of infection provention and control.
Strengthen supervision and inspection: The hospital should regularly check and evaluate the provention and control of gastroscope infection, find problems in time and take improvement measures.
Strengthen the publicity and education: The hospital should strengthen the publicity and education to the patients and medical workers to improve their awareness and ability of infection provention and control.
4. Prevention
of gastroscopy infection in special population
For special groups, such as the elderly, children and pregnant women, the prevention of gastroscopic infection should be more meticulous and thoughtful. These people are more vulnerable to pathogen infection because of their weak physical function or special physiological state. Therefore, before gastroscopy, these people should be assessed and screened in detail, and individualized preventive measure should be formulated according to their specific conditions.
V. Summary
The
prevention of gastroscope infection is a complex and meticulous work, which requires the joint efforts of hospitals, medical staff and patients. We can effectively reduce the risk of gastroscope infection by strengthening instrument disinfection, improving the operation level of medical staff, strengthening patient management and improving the hospital infection control system. At the same time, more attention and care should be given to special groups to ensure the safety and effectiveness of gastroscopy. Only in this way can we better protect the health and safety of patients.
