Difficult Peripheral IV Access Management

Introduction to Management Strategies

• For patients requiring 5 or fewer days of access, the American College of Physicians recommends using ultrasound-guided peripheral IV catheters as first-line for peripherally compatible infusates 1, 2, 3
• For non-peripherally compatible infusates, the decision for PICC placement should be individualized after discussing risks and benefits with the patient 1, 2, 3

Medium-Term Access Strategies

• For 6-14 days of expected use, ultrasound-guided peripheral IV catheters or midline catheters are preferred over PICCs 1, 2, 3
• Midline catheters (10-20 cm length) inserted into upper arm veins provide effective access for this duration 4

Longer-Term Access Strategies

• For 15-30 days, PICCs are appropriate 1, 2, 3
• For 31 days or more, tunneled catheters or implanted ports become appropriate options 1, 2, 3

Special Population Considerations

• In patients with stage 3b CKD or greater, avoid placing any devices in arm veins to preserve vessels for future hemodialysis access 1, 2, 5
• For patients with lymphedema, avoid insertion in limbs with lymphedema except in acute situations due to increased infection risk 4, 5

Best Practices for IV Access

• Use the smallest practical cannula size to minimize vein trauma 4, 5
• Do not routinely change peripheral cannulae at 72-96 hours 4, 5

Emergency Alternatives

• When IV access cannot be obtained in emergency situations, intraosseous access is the preferred alternative route 6
