Perineural catheters for continuous peripheral nerve blocks: a narrative review

Area of Science:

• Anesthesiology
• Pain Management
• Surgical Procedures

Background:

• Continuous peripheral nerve blocks (CPNBs) using perineural catheters are essential for prolonged analgesia.
• Recent literature lacks focus on perineural catheter utilization despite established benefits.
• Clinical challenges necessitate a review of current catheter practices.

Purpose of the Study:

• To provide a comprehensive overview of perineural catheter use in continuous peripheral nerve blocks.
• To discuss current perineural catheter designs and fixation techniques.
• To address complications and management strategies associated with perineural catheters.

Main Methods:

• This narrative review synthesizes existing literature on perineural catheters.
• Key areas explored include catheter design, fixation, complications, and management.
• The review focuses on practical aspects relevant to clinical application.

Main Results:

• Various perineural catheter designs are available, each with specific applications.
• Effective catheter fixation is crucial for preventing dislodgement and ensuring efficacy.
• Common complications include infection, nerve injury, and inadequate analgesia, with established management protocols.

Conclusions:

• Perineural catheters are vital for CPNBs, offering sustained pain relief.
• Understanding catheter design, fixation, and complication management is critical for optimizing patient outcomes.
• This review provides essential information for clinicians utilizing perineural catheters in pain management.
