A peripherally inserted central catheter, or PICC line, provides a valuable way to deliver medications, fluids, and nutrition over an extended period. While generally safe, monitoring the line for potential complications is essential. Serious issues can arise from improper care, accidental damage, or biological responses to the device. Knowing what to look for and when to contact a healthcare provider can help prevent minor problems from escalating into life-threatening situations.
Signs of a PICC Line Infection
Infection is one of the most serious risks associated with any central line, as it creates a direct path for bacteria into the bloodstream. Infections can range from localized issues at the insertion site to severe systemic infections, like sepsis.
Localized Infection Symptoms
If you notice any of these signs around the insertion site, contact your healthcare provider:
- Redness: An expanding area of redness around the catheter's entry point.
- Swelling and warmth: The area feels tender, puffy, or unusually warm to the touch.
- Drainage: Pus or discolored fluid leaking from the site. This may also have a foul odor.
- Pain: Increased or new pain, tenderness, or a burning sensation that doesn't improve.
- Red streaks: The appearance of red streaks tracking up the arm from the insertion site.
Systemic Infection (Sepsis) Symptoms
A systemic infection, or bloodstream infection (CLABSI), is a medical emergency. Seek immediate medical care if you experience:
- Fever and chills: A sudden, unexplained fever (over 100.4°F or 38.0°C) with shaking chills.
- Rapid heartbeat: An irregular or racing pulse.
- Confusion: Changes in behavior, dizziness, or disorientation.
- Feeling sick: Nausea, vomiting, or a general feeling of being unwell.
- Low blood pressure: A significant drop in blood pressure.
Recognizing a Blood Clot (Thrombosis)
A blood clot (thrombosis) can form in the vein where the PICC line is placed. This is a serious concern, as a dislodged clot can lead to a pulmonary embolism.
Signs of a blood clot include:
- Swelling: Unilateral swelling in the arm, hand, face, or neck on the same side as the PICC.
- Pain: Aching pain or tenderness along the vein, in the arm, or in the shoulder or chest.
- Redness and warmth: The affected limb may appear redder than usual and feel warm.
- Bulging veins: Veins in the arm or neck may appear more prominent or bulging.
Dealing with Mechanical Complications
Even with proper care, mechanical issues can affect a PICC line's function. These problems, such as occlusions or migration, can interfere with treatment and require medical intervention.
Signs of Catheter Occlusion or Blockage
An occlusion means the line is blocked, either partially or fully. It can be caused by a blood clot, a kink, or incompatible medications.
- Resistance to flushing: It is difficult or impossible to inject saline or medication into the line.
- Inability to draw blood: You cannot withdraw blood from the line.
- Leaking fluid: Fluid leaks from the catheter site or around the dressing.
- Pump alarms: Infusion pumps frequently alarm, signaling a blockage.
Signs of Catheter Dislodgement or Migration
If the catheter moves out of its correct position, it can cause significant problems. Common causes include coughing, vomiting, or excessive pulling.
- Change in length: A noticeable change in the length of the external tubing.
- Chest pain: Pain or discomfort in the chest, back, or neck.
- Ear gurgling: A strange gurgling or swishing sound in the ear.
- Pain during infusion: New pain or discomfort when fluids are being injected.
Comparison Table: Common PICC Line Complications
| Complication Type | Key Symptoms | What to Do |
|---|---|---|
| Infection | Fever, chills, redness, swelling, pus at site, unexplained pain | Seek immediate medical attention. |
| Blood Clot | Arm/neck/face swelling, pain, warmth, redness, shortness of breath, chest pain | Contact your healthcare provider immediately or go to the emergency department. |
| Occlusion | Resistance when flushing, inability to draw blood, pump alarms, fluid leakage | Contact your healthcare provider or home health nurse. Do not force flush. |
| Dislodgement | Change in tube length, pain during flushing, chest pain, gurgling in ear | Clamp the line (if possible), secure it, and contact your healthcare provider immediately. |
| Air Embolism | Sudden shortness of breath, chest pain, nausea, dizziness | Lay on your left side with head down, clamp the line, and call 911 immediately. |
Taking Preventative Action and Knowing When to Call for Help
To reduce the risk of complications, proper care is essential. This includes meticulous hand hygiene for both patients and caregivers, keeping the dressing clean and dry, and avoiding strenuous activities or heavy lifting with the affected arm. Patients should also avoid getting the PICC line wet while bathing or showering by using a waterproof cover.
In addition to the signs discussed above, there are other situations that warrant a call to your healthcare provider or home health nurse:
- Persistent soreness or discomfort beyond the first few days after insertion.
- Cracks, leaks, or other damage to the catheter tubing.
- Accidental pulling or removal of the catheter.
- Numbness or tingling in the fingers, hand, or arm.
- Skin irritation or blistering under the dressing.

Conclusion
While a PICC line is a safe and effective tool for long-term treatment, patient vigilance is a critical part of care. By understanding the key signs of infection, blood clots, occlusion, and dislodgement, you can respond quickly to potential complications. Consistent communication with your healthcare team and adherence to proper care protocols are the best ways to ensure a positive and safe treatment experience.
