This reference extract addresses Surgical site infection, a related subject. It does not cover every part of Surgical infection.. The article introduction is reproduced here, so you do not need to leave MedAtlas to read it. It may not match the latest official medical guidance.
A surgical site infection (SSI) develop when bacteria infiltrate the body through surgical incisions. These bacteria may come from the patient's own skin, the surgical instruments, or the environment in which the procedure is performed.
An infection is designated as an SSI if it develops at the site of a surgical wound, either because of contamination during surgery or as a result of postoperative complications. For the infection to be classified as an SSI, it should occur within 30 days after surgery or within 90 days if an implant is involved.
Surgical site infections that are limited to the skin and subcutaneous tissues are classified as superficial incisional SSIs. These infections are the most common type, accounting for more than 50% of all reported surgical site infections.
How this connects to General Surgery
Molecular investigation links DNA variation and gene regulation to RNA, proteins and cellular function. Assays measure selected molecular features with finite sensitivity and specificity; a detected variant or transcript does not automatically establish biological causation or a clinical diagnosis.

What the underlying subject studies
Surgery concerns anatomical conditions for which operative and nonoperative strategies may be considered. Understand the region, potential pathology, tissue blood supply, wound response and overall patient health before thinking about procedures.
How mechanisms and evidence connect
The perioperative period includes assessment, informed consent, infection prevention, physiological support, operative planning, recovery and follow-up. Technical procedures depend on specialist training and case-specific risk.
How to develop a sound explanation
Use a sequence diagram to connect indication, anatomy, pathophysiology and anticipated complications. A conceptual figure here is not a guide to performing an operation or managing an emergency.
