Histopathology and bacteriology of postinfusion phlebitis
International Surgery
|June 1, 1975
Abstract:
Veins from patients with postinfusion phlebitis showed three types of histopathologic changes--mild, moderate and severe. Severe change was usually associated with thrombus formation. Bacterial culture of tips of devices used in infusion yielded only 10% of positive cultures. This supports the view that postinfusion phlebitis is probably due to an irritating foreign body type reaction rather than infection.
Insights
Postinfusion phlebitis in veins is characterized by mild, moderate, or severe histopathologic changes, often with thrombus formation in severe cases. Evidence suggests this condition results from a foreign body reaction, not infection.
Area of Science:
- Medical research
- Pathology
- Infectious diseases
Background:
- Postinfusion phlebitis is a common complication of intravenous therapy.
- Understanding the underlying cause is crucial for effective prevention and treatment strategies.
Purpose of the Study:
- To investigate the histopathologic changes in veins associated with postinfusion phlebitis.
- To determine the role of bacterial infection versus foreign body reaction in the development of phlebitis.
Main Methods:
- Histopathologic examination of veins from patients with postinfusion phlebitis.
- Bacterial culture of infusion device tips.
Main Results:
- Three grades of histopathologic changes (mild, moderate, severe) were observed in affected veins.
- Severe phlebitis was frequently associated with thrombus formation.
- Only 10% of bacterial cultures from infusion device tips were positive.
Conclusions:
- The findings suggest that postinfusion phlebitis is primarily a foreign body reaction.
- Infection appears to play a minor role in the etiology of postinfusion phlebitis.
