The source of bacteria infected in the part of the chest surgery is a complex and multifaceted problem, involving pre-operative, mid-operative and post-operative links. The following are the main aspects of the analysis:
1. Microorganisms carried by patients themselves
• Before or during admission, the patient may have carried certain micro-organisms, such as bacteria, viruses or fungi. These micro-organisms may enter the surgery and cause infection as a result of the trauma of the operation or the temporary suppression of the immune system.
• In particular, micro-organisms carried by patients with chronic diseases or low immunity may be more likely to lead to post-operative infections. 2. Inadequate pre-operative preparedness
• Pre-operative skin cleanness and incomplete disinfection, which may result in skin microorganisms entering the surgery.
• Inadequate pre-operative preparation of surgical parts, such as unshaving hair or cleaning skin, may also increase the risk of infection. 3. Operating room environment
• Air, surfaces of objects and hands of medical personnel in operating rooms can be a medium for the transmission of microorganisms. If the air in the operating room is not sufficiently clean or the surface of the object is not thoroughly cleaned and disinfected, the microorganisms may be transported to the surgery through air or exposure.
Inadequate operation of the operation
• During the operation, micro-organisms may enter the surgery and cause infection if the medical staff does not strictly follow the sterile process, such as wearing no gloves, using no sterile devices or keeping the area clean.
• Neglect during the operation, such as cutting, stitching or bleeding, may also lead to tissue damage and microbial intrusion. Surgery equipment and implants
• Surgical devices and implants that have not been thoroughly cleaned and sterilized before the operation or that have been contaminated during their use can become vectors for the transmission of microorganisms.
• In particular, micro-organisms may enter the body with implants and cause infection if they are not treated in a rigorous manner before they are used, such as pacemakers, artificial joints, etc. 3. Antibiotic abuse
• During the course of the operation, the abuse of antibiotics or the failure to use antibiotics at the right time and at the right dose may lead to increased resistance of microorganisms, thereby increasing the risk of post-operative infections.
• The misuse of antibiotics can also disrupt the microbial balance in the body, leading to the emergence of pre-dominant microorganisms as dominant strains and causing infection.
1. Inadequate care for wounds
Post-operative care is essential to prevent infection. If the wounds are not cleaned and sterilized in a timely manner, or if the wound is contaminated by inappropriate dressing, the infection may occur. The risk of infection may also be increased by the patient ‘ s own lack of knowledge or mishandling of the wounds, such as frequent replacement of dressings, the use of inappropriate disinfectants or failure to provide care for the wounds as prescribed by the doctor. Post-operative haematoma and sepsis
• Post-operative haematoma and sepsis are among the common complications. If the haematoma and sepsis are not treated and diverted in a timely manner, they can become the growth environment of microorganisms and cause infection. 3. Patients with low immunity
• The immunity of post-operative patients is usually somewhat inhibited. If patients themselves have conditions such as low immunity or chronic disease, they are more vulnerable to microbial attack and infection. 4. Cross-infection in hospitals
• Hospitals are a microbial environment. Cross-infection and post-operative infections can occur if patients come into contact with other infected persons or share items such as medical devices.
Preventive measures
In order to reduce the risk of infection in the part of the chest surgery, the following precautions can be taken: 2. Strict adherence to sterile operating procedures and operating procedures. 3. Complete cleaning and disinfection of surgical devices and implants. 4. Rational use of antibiotics and avoidance of abuse. 5. Strengthening post-operative injury care and patient immunization. 6. Strict control of the occurrence of cross-infection in hospitals.
In the light of the above, the sources of bacterial infections in the part of the chest surgery are multiple, including pre-operative, mid-operative and post-operative. Reducing the risk of infection requires a concerted effort by medical personnel, patients and hospitals to take a range of preventive measures to ensure the safety and effectiveness of operations.
