The Coach SpaceIn the complex world of modern healthcare, port catheters are like the unsung heroes, quietly playing a crucial role in delivering long-term intravenous treatments to patients. These little implants, tucked beneath the skin, are the secret passage to the bloodstream, making it easy to give important medications, chemotherapy drugs, and fluids.
Port catheters are the lifeline for folks dealing with ongoing health issues, making it simple to get the treatments they need straight into their veins. But, with great benefits come some risks – like port catheter-related infections (PCIs).
PCIs cover a range of germ-related issues, from annoying skin problems to serious bloodstream infections. They’re a headache for both healthcare pros and patients. And that’s not even all!
According to the American Society of Clinical Oncology, besides the risk of PCIs, these ports also pose the threat of clots and blockages which can be a painful experience for the patients. Other, rarer complications associated with port catheters include a twist or movement in them after being placed inside your body.
From defining what port catheters are to uncovering the infections they can cause and how to prevent them, we’re here to give you the lowdown.
Understanding Port Catheter-related Infections
Also known as port-a-caths or implanted ports, port catheters are small medical devices implanted beneath the skin to provide long-term access to the bloodstream.
They consist of a port connected to a catheter, which is inserted into a large vein, typically in the chest area.
TorHoerman Law notes that port catheters come in various types, including single-lumen and double-lumen ports, with each type offering specific advantages depending on the patient’s needs and treatment requirements.
Let’s learn more about port catheter-related infections below:
Catheter-Related Bloodstream Infections (CRBSIs)
Catheter-related bloodstream infections (CRBSIs) occur when bacteria or fungi contaminate the catheter’s surface, subsequently entering your bloodstream. These infections are a significant concern among patients with central venous catheters, implanted port catheters, or other indwelling medical devices.
CRBSIs typically develop when microorganisms form a biofilm on the surface of the catheter. This film shields them from antimicrobial agents and the host immune response. Biofilm-associated infections are often challenging to treat and may necessitate catheter removal to resolve the infection fully.
The factors that contribute to the development of CRBSIs are the following:
- Improper catheter insertion techniques
- Inadequate sterilization procedures
- Contamination of catheter hubs and connectors during catheter care
- Prolonged catheterization
- Immunocompromised status of the patient.
Clinical manifestations of CRBSIs can vary but often include fever, chills, hypotension, and signs of systemic inflammation. Their diagnosis typically involves imaging studies, such as ultrasound or chest X-ray.
In 2023, BMC conducted a study of the prevalence of infections in patients receiving treatment or medication through catheters. The results of the study indicated that CRBSIs were the most prevalent of all infections, diagnosed in 34.2% of the patients.
But how can such prevalent infections be managed? Here’s the answer:
Managing CRBSIs usually involves a combination of antimicrobial therapy and catheter management strategies. In some severe cases, catheter removal may be necessary to treat the infection and prevent further complications effectively.
Subcutaneous Pocket Infections
When a port catheter is implanted inside your body, a small pocket is created under the skin to hold the device securely in place. Subcutaneous pocket infections happen when bacteria or other pathogens enter the pocket. These pathogens can multiply and cause an infection, leading to symptoms such as redness, swelling, warmth, tenderness, or drainage at the site of the pocket.
Treatment for subcutaneous pocket infections typically involves antibiotics to target the causative pathogens. In severe infections, surgical removal of the implanted device and debridement of the infected tissue may be required.
Tunnel Infections
Implanting the port catheter inside your body typically creates a tunnel under your skin to allow it to travel from the port reservoir to the vein where it is inserted.
Tunnel infections can occur when bacteria or other pathogens enter the tunnel, either during the implantation procedure or afterward. These pathogens can then multiply and cause an infection, leading to symptoms such as redness, swelling, warmth, tenderness, or drainage along the path of the tunnel.
Prevention of tunnel infections involves ensuring proper sterilization techniques during the implantation procedure, maintaining strict sterile conditions during device insertion, and promoting good wound care practices post-implantation. Healthcare providers may also prescribe prophylactic antibiotics before the procedure in certain high-risk individuals to reduce the risk of infection.
If you’re wondering how common is it to get an infection from a port catheter, you must understand that while rare, PCIs are a very real possibility. Bard PowerPort, a port catheter device developed by Bard Access Systems Inc., is a perfect example of how the root cause of the infections might lie at the manufacturer’s end.
In April 2023, when a large number of patients complained about suffering from infections and injuries while using the port catheter, they came together to file the Bard Power Port lawsuit against the manufacturer. The lawsuit, which has now become a multi-district litigation (MDL) is actively advancing. If you are or know someone affected by Bard Power Port, you must start considering hiring a lawyer today.
Prevention Strategies to Avoid PCIs
Preventing infections associated with port catheters is a critical aspect of patient care. Only a multifaceted approach – including proper insertion techniques, diligent catheter maintenance, and the judicious use of antimicrobial strategies – can lead to its comprehensive prevention.
Let’s break down three prevention strategies below:
Proper Port Catheter Insertion Techniques
Proper insertion techniques and site preparation play a pivotal role in reducing the risk of port catheter-related infections. Healthcare providers must adhere to strict sterile techniques during catheter insertion procedures to minimize the introduction of pathogens. This includes thorough hand hygiene, gowning, gloving, and draping to create a sterile field.
Additionally, meticulous skin antisepsis using an appropriate antiseptic solution, such as chlorhexidine or povidone-iodine, helps reduce the microbial load at the catheter insertion site, lowering the risk of infection. Careful consideration should also be given to catheter placement, with healthcare providers assessing vascular anatomy to select the most suitable vein and minimize the risk of complications.
Port Catheter Care and Maintenance
Daily assessment and monitoring of the catheter insertion site and surrounding skin for signs of infection, such as redness, swelling, warmth, or discharge, are paramount. Healthcare providers should conduct thorough visual inspections during routine care visits and educate patients on the importance of self-monitoring for any changes in the catheter site.
Proper catheter flushing with an appropriate solution, such as saline or heparinized saline, helps prevent catheter occlusion and microbial colonization, reducing the risk of infection.
Securement of the catheter and maintenance of a sterile occlusive dressing over the insertion site also play a crucial role in preventing accidental dislodgement and minimizing the risk of microbial contamination.
Antimicrobial Strategies
The use of catheters coated or impregnated with antimicrobial agents has been shown to reduce the risk of catheter-related infections, particularly in high-risk patients.
According to the National Library of Medicine, antimicrobial agents are therapeutic substances that can both prevent and treat infection. They target the key steps of cell metabolism, killing microorganisms before they can do any damage. Antibiotics, antivirals, antifungals, antiseptics, and antiparasitics are all examples of these agents.
To prevent catheter-related infections, antimicrobial lock solutions can be instilled into the catheter lumen between medication administrations. Topical antiseptics applied to the catheter insertion site, such as chlorhexidine or alcohol-based solutions, may also help reduce microbial colonization and lower the risk of infection.
