Critically ill patients and those who require total parenteral nutrition, require prolonged or permanent intravenous access. These patients are prone to infection, cellulite, and other complications at the injection site. Totally implantable venous access devices (TIVAD) were developed to overcome the problems associated with repeated venous access in patients needing long- term intravenous therapy. By implantation of this device, the peripheral veins of the patients are saved and patients do not suffer from numerous injection sites that are needed for injection of drugs or recurrent sampling of blood.
TIVADs are also called Ports or Portacaths®. A Port is a type of central venous catheter usually made of silicon rubber or polyurethane. The implantable port requires surgical placement under general anaesthetic. It is placed completely under the skin, usually the chest or arm, and consists of two components:
Medication is given into the TIVAD by inserting a non-coring needle through the skin into the portal chamber and injecting or infusing the drugs which will travel along the catheter into the veins. A sterile, transparent, semi-permeable adhesive dressing is used to secure the needle in place.
This device is inserted in a central vein and therefore it works for a long time and also because of the wide surface of the port, every time, one needle is inserted into the port that can be used for sampling or injection of drugs at the same time. On the other hand, because of insertion into the central vein, injection of hypertonic solutions or drugs that are used for chemotherapy cannot damage the blood vessels.
The main benefits are that the Port is a secure method for administering drugs and medicines that cannot be given through smaller veins. Because the Port is placed beneath the patient’s skin, it is quite simple to look after and live with. The infection rates are lower compared to central venous catheters.
Even though many patients benefit from the insertion of an implantable catheter port in the absence of any secondary effects, any surgical implantation can nevertheless lead to pre or post-operative complications. Some of these complications are related to the surgery and the insertion of an implantable catheter port. Some of these complications can be solved by conservative management or local anesthesia and in some cases, the TIVAD must be extracted and implanted another one.
We conclude that the patients must select reliable TIVAD that is produced from nonthrombogenic materials with high resistance to tearing and high flexibility.
That is why GreeMed offers you the best option, Sitimplant by Vygon, therefore the patients can be satisfied with this device and we can help them feel better and improve their quality of life.
