I. What is PICC?
PICC stands for “Peripherally Inserted Central Catheter.” It is inserted through a peripheral vein in the arm, with the catheter tip positioned in the lower one-third of the superior vena cava. It provides a safe and reliable venous access for patients who require infusion of hyperosmolar solutions (e.g., glucose concentration >10%, total parenteral nutrition, chemotherapy drugs), long-term intravenous therapy, pressure infusions, or those with poor peripheral venous access.
II. Daily Self-Examination: Early Detection, Early Management
In winter, when more clothing is worn, it is recommended to check the catheter at least three times a day: before dressing in the morning, during lunch break, and after undressing in the evening. In summer, with lighter clothing, inspections can be done more frequently.
Please pay attention to the following: any unusual odor around the catheter, redness, swelling, or exudate at the insertion site, loosening or lifting of the transparent dressing, or presence of blood backflow in the catheter. If any abnormalities are noted, contact your nurse immediately.
III. Daily Living Precautions
PICC placement does not interfere with most routine daily activities such as cooking, washing dishes, or sweeping. However, the following precautions should be observed:
1. Activities and Exercise
Avoid heavy lifting, dumbbell exercises, pull-ups, or other weight-bearing activities.
Refrain from swimming, soaking in baths, or any activities that may submerge the sterile area in water.
Avoid vigorous swinging or excessive bending of the elbow joint on the catheterized arm.
2. Dressing and Sleeping
When dressing: put on the sleeve on the catheterized side first, followed by the healthy side.
When undressing: remove the sleeve on the healthy side first, followed by the catheterized side.
Avoid sleeping on the catheterized arm.
For pediatric patients: parents should instruct children not to play with the external portion of the catheter to prevent damage or accidental dislodgement.
3. Medical Contraindications
Avoid applying a blood pressure cuff to the catheterized arm.
Minimize arm movement within 24 hours after insertion. If bleeding occurs at the puncture site, limit activity until bleeding stops; normal activity may resume thereafter.
IV. Bathing Instructions
Only showering is permitted while the PICC is in place. Baths, soaking, and saunas are strictly prohibited.
Before showering, wrap the elbow area with 2–3 layers of plastic wrap and secure the edges tightly with tape to ensure a complete seal. After showering, check whether water has penetrated under the dressing. If the dressing is wet, it should be changed promptly at a healthcare facility.
V. Regular Maintenance During Treatment Intervals
During the treatment interval after discharge, routine maintenance must be performed every 7 days at the hospital. This includes changing the transparent dressing, flushing the catheter, and replacing the infusion connector. Please keep track of your next scheduled maintenance appointment and do not delay or skip visits even in the absence of symptoms.
Your PICC is your “lifeline.” With proper care and regular maintenance, it will support you safely and steadily throughout your entire treatment journey. If you have any questions or concerns, please do not hesitate to contact your responsible nurse or the PICC specialty clinic.
