Katetrointia

Katetrointia is a term used in medical education and discussion to describe a proposed complication associated with catheter-based interventions. It refers to a systemic or localized inflammatory reaction triggered by intravascular or intrathecal catheterization, not attributable solely to infection.

The name derives from katheter, the medical term for catheter, combined with the suffix -ia to denote a medical condition. It is a neologism used in discussions of catheter-related complications to illustrate non-infectious inflammatory responses.

Causes and risk factors in the conceptual framework include endothelial irritation from catheter manipulation, biofilm formation on catheter surfaces, procedural duration, repeated catheter access, patient immune status, and certain catheter materials or coatings. These factors are thought to contribute to a localized or systemic inflammatory milieu that mimics infectious signs without positive cultures.

Clinical features vary but may include localized pain, erythema or swelling at the insertion site, fever, leukocytosis, and transient organ dysfunction in rare cases. Imaging can show local inflammation or catheter-related tissue changes, aiding differentiation from typical infection.

Diagnosis relies on clinical criteria supplemented by laboratory markers and imaging. Distinguishing katetrointia from infection requires careful assessment for systemic infectious signs, culture results, and response to anti-inflammatory measures. In practice, diagnosing such a non-infectious inflammatory process remains hypothetical and is often used for teaching purposes rather than as a formal, guideline-established entity.

Management focuses on catheter assessment—removal or repositioning when feasible—along with anti-inflammatory therapy and supportive care. Antibiotics are reserved for suspected or confirmed infection. Prognosis depends on severity and comorbidity; most scenarios are mild with prompt management.
