Clinical Practice Guidelines for Breast Cancer Implantable Intravenous Infusion Ports: Chinese Society of Breast Surgery Practice Guidelines 2021
Implantable intravenous (IV) ports have become an essential component in the management of breast cancer patients, particularly for those requiring long-term infusion of chemotherapy drugs, highly osmotic or viscous fluids, intravenous nutrition, or blood products. The Chinese Society of Breast Surgery (CSBrS) has developed comprehensive clinical practice guidelines to standardize the application of these devices, ensuring optimal patient outcomes and minimizing complications. These guidelines are based on extensive literature research, expert discussions, and the grading of recommendations assessment, development, and evaluation (GRADE) methodology. The target audience for these guidelines includes Chinese breast disease specialists, and the recommendations are designed to provide a reference for physicians specializing in breast cancer and other related fields.
Indications for Implantable IV Ports
The primary indication for the use of implantable IV ports is in breast cancer patients who require long-term infusion of chemotherapy drugs, highly osmotic or viscous fluids, intravenous nutrition, or blood products. The guidelines strongly recommend the use of IV ports for these patients, with a Level I evidence and Class A recommendation strength. This recommendation is based on the proven benefits of IV ports in reducing the complications associated with repeated venous access and improving the quality of life for patients undergoing long-term treatment.
Channel Selection for Implantable IV Ports
The choice of venous access for implantable IV ports is critical to ensure the safety and efficacy of the device. The guidelines recommend the use of the subclavian vein, internal jugular vein, or noble vein as the preferred channels for IV port placement, with a Level I evidence and Class A recommendation strength. These veins are associated with lower complication rates and better long-term outcomes. In cases where the superior vena cava is obstructed or other special circumstances exist, the femoral vein may be considered as an alternative, with a Level II evidence and Class A recommendation strength.
Catheter Tip Position in Infusion Ports
The position of the catheter tip is a crucial factor in the successful use of implantable IV ports. The guidelines recommend that the catheter tip be placed in the lower one-third of the superior vena cava or at the junction of the superior vena cava and the right atrium, both with a Level I evidence and Class A recommendation strength. These positions are associated with a lower risk of complications such as thrombosis and catheter malposition. Proper positioning of the catheter tip is essential to ensure the safe and effective delivery of infused medications and fluids.
Catheter Tip Positioning Methods
Accurate positioning of the catheter tip is achieved through the use of intra-operative X-ray or post-operative chest radiographs, both with a Level I evidence and Class A recommendation strength. Intra-operative electrocardiogram (ECG) localization is also recommended as an effective and economical method for ensuring correct catheter tip placement, with a Level I evidence and Class A recommendation strength. These methods significantly reduce the risk of catheter tip malposition and the need for subsequent adjustments.
Prevention and Management of Common Complications
The guidelines provide detailed recommendations for the prevention and management of common complications associated with implantable IV ports. These complications include pneumothorax, hemothorax, air embolism, misdirected artery puncture, catheter-associated bloodstream infections, and catheter-associated thrombosis.
Pneumothorax, Hemothorax, Air Embolism, and Misdirected Artery Puncture
To prevent these complications, the guidelines recommend the use of ultrasound localization or intra-operative ultrasound-guided venipuncture, with a Level I evidence and Class A recommendation strength. These techniques reduce the risk of accidental puncture of adjacent structures and improve the safety of the procedure.
Catheter-Associated Bloodstream Infections
Catheter-associated bloodstream infections are a significant concern in patients with implantable IV ports. The guidelines recommend strict aseptic techniques during the insertion and maintenance of the ports. Empirical use of antibiotics is recommended until drug sensitivity test results are available, with the selection of antibiotics based on the identified infecting agent. If treatment is ineffective, the IV port should be removed, with a Level II evidence and Class A recommendation strength.
Catheter-Associated Thrombosis
To prevent catheter-associated thrombosis, the guidelines recommend avoiding repeated punctures and ensuring correct catheter tip positioning. Once thrombosis occurs, anticoagulation is the preferred treatment, with a Level II evidence and Class A recommendation strength. Thrombolytic therapy is generally not recommended due to the associated risks.
Infusion Port Maintenance
Proper maintenance of implantable IV ports is essential to ensure their long-term functionality and to prevent complications. The guidelines provide detailed recommendations for the maintenance of IV ports, including the use of non-invasive needles, assessment of catheter return and flow smoothness, and the use of sterile dressings.
Maintenance by Professionally Trained Healthcare Professionals
The guidelines strongly recommend that the maintenance of IV ports be performed by healthcare professionals who have received specialized training in infusion therapy, with a Level I evidence and Class A recommendation strength. This ensures that the ports are properly cared for and reduces the risk of complications.
Use of Non-Invasive Needles
Non-invasive needles should be used for puncture, with replacement every seven days, with a Level I evidence and Class A recommendation strength. These needles protect the silicone septum of the injection seat and reduce the risk of damage to the port.
Assessment of Catheter Return and Flow Smoothness
After puncture, the catheter return and flow smoothness should be assessed to ensure proper function of the IV port, with a Level I evidence and Class A recommendation strength. This helps to identify any issues with the catheter and allows for timely intervention.
Use of Sterile Dressings
Sterile dressings are required to cover the puncture point, with sterile clear dressings changed at least every seven days and sterile gauze dressings changed at least every two days, with a Level I evidence and Class A recommendation strength. This helps to prevent infection and ensures the cleanliness of the port site.
Flushing and Sealing the Tube
The guidelines recommend flushing and sealing the tube with saline or 100 U/mL heparin saline, with a Level I evidence and Class A recommendation strength. This helps to maintain the patency of the catheter and prevents the formation of blood clots.
Maintenance Between Treatments
IV ports should be maintained at least every four weeks between treatments, with a Level I evidence and Class A recommendation strength. This ensures that the port remains functional and reduces the risk of complications.
Removal of Implantable IV Ports
Implantable IV ports that are no longer needed or are not suitable for continued use should be removed. After removal, the device should be checked for integrity to ensure that no fragments remain in the patient’s body. The guidelines emphasize the importance of proper removal techniques to prevent complications and ensure patient safety.
Conclusion
The clinical practice guidelines for breast cancer implantable intravenous infusion ports developed by the Chinese Society of Breast Surgery provide a comprehensive framework for the safe and effective use of these devices. The guidelines cover all aspects of IV port use, from indications and channel selection to catheter tip positioning, prevention and management of complications, and maintenance. By following these guidelines, healthcare professionals can ensure optimal outcomes for breast cancer patients requiring long-term infusion therapy. The recommendations are based on the best available evidence and expert consensus, providing a valuable resource for physicians specializing in breast cancer and other related fields.
