PICC Line Care and Maintenance

General Recommendations

The American College of Physicians recommends flushing PICC lines with normal saline after each use, changing transparent dressings weekly or when soiled, and using a dedicated lumen for parenteral nutrition if multilumen catheters are employed 1, 2
The American College of Physicians suggests that routine use of chlorhexidine-impregnated dressings is inappropriate without documented adherence to basic infection-prevention efforts or in the absence of high catheter-related bloodstream infection rates 1, 2

The Infusion Nurses Society recommends using normal saline rather than heparin to maintain catheter patency and prevent lumen occlusion 1, 2
The Clinical Nutrition society suggests performing weekly flushes with normal saline for PICCs not in active use 3
The Clinical Nutrition society recommends always using a 10 mL or larger syringe to avoid excessive pressure that could damage the catheter 4, 5
The Praxis Medical Insights society suggests employing turbulent push-pause flushing technique for optimal clearance 5

The American College of Physicians recommends applying sterile gauze between the PICC entry site and adhesive dressing for the first 1-2 days post-insertion, then transitioning to clear transparent dressings 1, 2
The American College of Physicians suggests using transparent dressings that permit visual site examination 1, 2
The Annals of Oncology recommends cleaning the insertion site with chlorhexidine solutions with alcohol 3
The Annals of Oncology suggests allowing adequate drying time after antiseptic application to avoid blood contamination 3

The Clinical Nutrition society recommends using sutureless stabilization devices rather than sutures to secure PICCs 4, 6
The Clinical Nutrition society suggests using manufactured catheter stabilization devices, such as StatLock, instead of sterile tapes 4
The Clinical Nutrition society recommends using subcutaneously anchored stabilization devices for medium to long-term PICCs (>1 month) to prevent migration and save time during dressing changes 6

The American College of Physicians recommends defaulting to single-lumen devices to reduce complications, unless there is a documented rationale for multilumen PICCs 1, 2, 7
The American College of Physicians suggests dedicating one lumen specifically for parenteral nutrition in multilumen catheters 6
The American College of Physicians recommends collaborating with pharmacists or vascular access operators before ordering a PICC to clarify device needs 1, 2, 7

The Annals of Oncology recommends verifying catheter tip position radiologically with intraoperative fluoroscopy or post-operative chest X-ray 3
The American College of Physicians suggests that the ideal position is the lower third of the superior vena cava or cavoatrial junction 1, 2, 7
The American College of Physicians recommends adjusting the PICC when the tip is in the upper or middle third of the superior vena cava or right ventricle 1, 2, 7

The Clinical Nutrition society recommends using infusion pumps for continuous parenteral nutrition and following appropriate flushing protocols to prevent intraluminal obstruction 4
The Clinical Nutrition society suggests avoiding routine use of the catheter for blood product infusion, blood withdrawal, or contrast medium injection 4
The American College of Physicians recommends never advancing migrated PICCs—instead, performing guidewire exchange if there are no signs of infection 1, 2

The Annals of Oncology recommends collecting paired blood cultures from the catheter and peripheral vein before starting antibiotics if catheter-related bloodstream infection is suspected 3
The Annals of Oncology suggests using alcohol, iodine tincture, or alcoholic chlorhexidine (≥0.5%) rather than povidone-iodine for skin preparation 3
The Annals of Oncology recommends taking a swab of any exudate at the exit site for culture and Gram staining 3
The Annals of Oncology suggests that antimicrobial prophylaxis is not recommended for PICC insertion or maintenance 3

The Clinical Nutrition society recommends never using syringes smaller than 10 mL for flushing or clearance attempts to avoid catheter damage from excessive pressure 4, 5
The Annals of Oncology suggests avoiding femoral vein insertion due to increased infection and thrombosis risk 3
The MMWR Recommendations and Reports recommends not routinely applying topical antimicrobial ointments to the insertion site 8
The Clinical Nutrition society suggests removing PICCs as soon as they are no longer clinically necessary to minimize complication risk 4
