[Peripheral intravenous catheter-related phlebitis]

Area of Science:

• Medical Complications
• Infectious Diseases
• Vascular Access

Background:

• Phlebitis is a frequent complication associated with intravenous (IV) catheter use.
• Thrombophlebitis, a specific type of phlebitis involving a blood clot, can arise from IV catheterization.
• Understanding the different types and risk factors of phlebitis is crucial for patient care.

Observation:

• Two cases illustrate phlebitis complications: septic thrombophlebitis with Staphylococcus Aureus in an immunocompromised patient and chemical phlebitis in another patient.
• Septic phlebitis, though rare, poses significant risks, while chemical and mechanical phlebitis are more common but generally less severe.
• Identified risk factors for phlebitis include female sex, prior phlebitis episodes, forearm insertion sites, emergency catheter placement, and antibiotic administration.

Findings:

• Randomized controlled trials have not demonstrated benefits from routine replacement of peripheral IV catheters every 72-96 hours.
• A recent Cochrane Review supports replacing peripheral IV catheters based on clinical indication rather than a fixed schedule.
• This shift challenges previous standard practices regarding IV catheter maintenance.

Implications:

• Clinical practice guidelines for IV catheter management should be updated to reflect the latest evidence.
• Focusing on clinical indication for replacement may reduce unnecessary interventions and associated costs.
• Further research may explore optimal strategies for preventing and managing phlebitis in diverse patient populations.
