What causes surgical wound infections after surgery?

Introduction
In general, postoperative wound infections may result from inadequate sterilization, prolonged exposure of the incision, contamination during surgery, improper surgical techniques, or inappropriate postoperative care. Additionally, some patients with poor immune function are more susceptible to pathogens such as bacteria, increasing the risk of postoperative infection. If an infection occurs after surgery, it is recommended to inform the doctor promptly.

In general, postoperative wound infections may occur due to inadequate sterilization, prolonged exposure of the incision, intraoperative contamination, improper surgical techniques, or inadequate postoperative care. A detailed analysis is as follows:

1. Inadequate Sterilization

Surgery must be performed in a sterile environment. If preoperative disinfection of the operating room, surgical instruments, or the patient's skin is insufficient, pathogenic microorganisms may be introduced into the incision during surgery, leading to wound contamination and subsequent postoperative infection.

2. Prolonged Exposure of the Incision

Extended exposure of the incision can cause local tissue dehydration and reduced resistance. Additionally, it increases the risk of airborne pathogens contaminating the wound, which may lead to infection.

3. Intraoperative Contamination

If a surgeon's gloves or gown are torn during the procedure, pathogens may be introduced into the incision, causing infection. In surgeries involving sites such as the gastrointestinal tract, bacteria from within the tract may be transferred to the incision site, resulting in contamination and postoperative wound infection.

4. Improper Surgical Technique

If aseptic principles are not strictly followed during surgery, wound infection may result, leading to postoperative infection. Furthermore, when operating on infected lesions, incomplete removal of the infected tissue may also lead to postoperative infection.

5. Inadequate Postoperative Care

If proper local wound care is not maintained after surgery, postoperative infection may occur. Failure to keep the wound clean and dry or to regularly disinfect the site can all contribute to infection.

In addition, patients with poor immune function are more susceptible to invasion by bacteria and other pathogens, increasing the risk of postoperative infection. If signs of infection occur, patients should promptly inform their doctor for timely management and to prevent serious complications.

Why is chemotherapy required after major cancer surgeries?
In general, patients with cancers such as lung cancer, gastric cancer, and breast cancer often require chemotherapy after surgery due to surgical trauma and stress, decreased immune function, minimal residual disease, active cell proliferation, and increased potential for metastasis.

Can someone who has had surgery for myocardial infarction receive the herpes vaccine?
In general, whether patients who have undergone surgery for myocardial infarction can receive the herpes zoster vaccine should be determined based on a comprehensive assessment of postoperative recovery and cardiac function stability. If any discomfort occurs, prompt medical consultation is recommended. Vaccination against herpes zoster in post-myocardial infarction patients requires individualized evaluation, with emphasis on cardiac function stability and postoperative recovery status. Recombinant vaccines are considered safer than live attenuated vaccines.
