Why should breast cancer chemotherapy be implanted into infusion port?

Why should PICC be inserted through peripheral venipuncture or the infusion port be buried in the chest during chemotherapy? If you spend money, you have to wash the tube regularly, and there may be complications such as catheter failure, thrombosis and infection. Is it meaningful?

Chemotherapy is administered intravenously, such as intravenous infusion and arterial administration, and intravenous chemotherapy is the most commonly used method. Extravascular administration includes oral administration, intrathecal administration and intraperitoneal perfusion. The effective rate of intravascular chemotherapy is generally higher than that of extravascular chemotherapy.

Chemotherapeutic drugs are mostly corrosive, and the initial drug concentration in vein is very high during infusion, which stimulates blood vessels to produce inflammation, arteriosclerosis and pain. After chemotherapy, many patients can see that the skin of upper limbs has obvious pigmentation along blood vessels, which is caused by the stimulation of chemotherapy drugs. If chemotherapy drugs extravasate, it will be even worse. The skin around the infusion site will fester and necrosis, and some may be severely disabled!

In order to avoid the damage of chemotherapy to skin, blood vessels and limbs, PICC catheter and infusion port appeared.

PICC catheter appeared earlier. Catheter was inserted through cubital fossa vein, through brachial vein, axillary vein and subclavian vein to superior vena cava. The diameter of the superior vena cava is more than 2cm, and the drug has blood buffer here, so the circulation is faster and the stimulation is much less.

However, part of PICC catheter is exposed outside the skin, which is inconvenient in life and easy to be infected, so there is an infusion port. The infusion port enters the superior vena cava from the subclavian vein in the chest, and the infusion end is buried under the skin, which makes life much more convenient and almost eliminates infection.

Intravenous catheter, after all, is a foreign body, there will be some complications, such as catheter blockage, stimulation of blood vessel wall, thrombosis, etc., which need regular maintenance and inspection. When there are serious complications, or when chemotherapy is over and there is no treatment for a long time, the catheter can be removed. I'm Dr. @ Liu Yongyi, thank you for reading!

In fact, not only breast cancer chemotherapy, but also many cancers in the process of adjuvant chemotherapy, doctors will advise patients to place infusion lines, such as PICC and infusion port, according to the patient's situation.

Then the question is, why did the doctor suggest inserting this special infusion line? Don't listen to the doctor, okay?

First of all, why did the doctor suggest catheterization?

In fact, the reason is very simple. The different stages and types of tumors determine the length of chemotherapy cycle. The short one needs 4 cycles, and the long one needs 12 cycles, and the time can range from 3 months to 7 months. Therefore, for many patients, it is very meaningful to put a tube to avoid the pain of needle puncture every time.

In addition, as we all know, chemotherapy drugs have great cytotoxicity, which can be said to be very, very serious damage to blood vessels. If you choose to take medicine from the peripheral vein without catheter every time, even people as strong as cattle can't stand repeated injuries (many patients without intubation for various reasons have different degrees of phlebitis after chemotherapy, and even need to be referred to vascular surgery for treatment in severe cases)!

The third reason is that if chemotherapy drugs are accidentally extravasated when administered through peripheral vein, it will cause permanent necrosis of the surrounding skin in a short time if they are not treated correctly in time.

Let's talk about another question. Can we not listen to the doctor?

The answer is self-evident, intubation is not once and for all, and not everyone is suitable for intubation, so the choice is in the patient himself. Infusion port and PICC have their own advantages and disadvantages (PICC can be punctured by a certified nurse in the ward and can last for about one year. During the period, it is necessary to go to the hospital once a week for pipeline maintenance to prevent catheter-related blood flow infection, and the cost is 3,000-5,000 yuan; The infusion port needs a doctor to put it in the operating room and flush the tube once a month. Every time a drug is injected, it needs to be percutaneously "stuck into the port". For example, tubes can generally be left in the body permanently, and the cost is about 7000-9000 yuan).

In fact, I personally think it is feasible to insert a tube if physical and economic conditions permit. On the one hand, to ensure the normal progress of chemotherapy, on the other hand, if there is an emergency or sudden change in the course of chemotherapy, catheterization is undoubtedly a "life channel", which can win a chance for treatment!

Chemotherapy is systemic chemotherapy for malignant tumors. Epirubicin, the most powerful and commonly used chemotherapy drug for breast cancer, is extremely harmful to blood vessels, so it cannot be directly infused intravenously, and it needs to be implanted into an intravenous infusion port or an intravenous infusion tube. Compared with intravenous infusion tube (commonly used at present), implantable intravenous infusion port is the most advanced intravenous drug delivery device in the world, providing patients with long-term intravenous access. Has the following obvious advantages: 1. Reduce the risk of infection; 2. Convenient for patients: it is not easy to be noticed by others when implanted under the skin. At the same time, subclavian implantation will not affect activities, and you can take a bath, participate in swimming and other activities without infusion and needle embedding. 3. Reduce the times of puncturing blood vessels, protect blood vessels and reduce the chance of drug extravasation. 4. The maintenance is simple, and it can be maintained once every 4 weeks during the treatment interval. The picture shows the wound recovery and wound area after the intravenous infusion port implantation 10.

Infusion PORT, also called port clinically, is a professional infusion device placed in the body to reduce the stimulation of drugs on patients' blood vessels.

It is divided into three parts: non-invasive needle (butterfly wing needle), catheter inserted into subclavian vein, and injection seat (port body) buried under the skin and connected with infusion needle. The injection seat is connected with the catheter inserted into subclavian vein, forming a long-term vascular passage, which plays a role similar to the port, so it is called "infusion port".

Everyone can use the infusion port?

Infusion ports can be used for the following four types of patients:

① Patients who need long-term repeated infusion and administration;

② Patients receiving blood drawing, blood transfusion and nutrition drug infusion;

③ Patients injected with contrast agent;

④ Patients who use chemotherapy drugs for a long time.

Where is the infusion port?

Artifact is called artifact, there must be a reason. Let's talk about the benefits of the infusion port first, and Huzhujun will summarize it for everyone.

(1) No tube is exposed, so as to avoid others' suspicion and harassment.

Compared with PICC catheter and deep vein catheter, there is no exposed catheter at the infusion port, and even if chemotherapy is needed, it will not cause others to ask you or look strange.

② It does not affect bathing and daily life.

The infusion port is placed under the skin, so you can take a bath and your daily life is more convenient.

③ The probability of infection is small.

Because the infusion port is completely buried in the body, it is not easy to be infected, so there is no need to worry about itching, redness and other problems like PICC catheterization.

④ Avoid drug leakage.

Ordinary catheterization may cause leakage of chemotherapy drugs due to improper posture and excessive movements, stimulate blood vessels, and even cause irreversible damage. In this respect, the infusion port has great advantages and is basically impossible.

⑤ It can be used repeatedly for a long time.

According to the instruction manual of the infusion port, 19G non-invasive puncture needle 1000 times, butterfly wing needle can be used continuously for 7 days, and the infusion port can be used for 19 years, but according to clinical experience, an infusion port can be reused for more than 10 years.

⑥ Simple operation and maintenance, and acceptable price.

Placing an infusion port requires only a minor operation in the operating room for 15-20 minutes, and almost no pain will be felt. The maintenance after placing is relatively simple, about 6000~8000 yuan.

How to maintain the infusion port daily?

① Don't be too active during infusion, which will cause the needle to come out;

② After operation, the conventional wound should be replaced every 2-3 days, the auxiliary materials should be kept dry, and the surrounding skin can be observed with a mirror;

③ Generally, the stitches are removed 10- 14 days after implantation, and it is recommended to wait until the local wound heals before taking a bath; Usually be careful not to hit the part of the infusion port by gravity;

(4) If you need to get the needle out of the hospital, you should keep the dressing intact. If it is loose and wet, it needs to be changed immediately; The needle can only be kept for 7 days, and the needle should be pulled out of the hospital after the expiration;

⑤ Nursing care of washing and sealing the infusion port every four weeks in regular hospitals;

⑥ Patients placed at the infusion port can do housework and walk normally; But avoid physical activities, such as lifting dumbbells and boxing.

How's it going? Does the "chemotherapy artifact" open the door to a new world, and friends all want to have this artifact? However, if you can use it, you should consult the attending doctor!

Why should breast cancer patients be implanted into the infusion port? I think it's because I'm afraid that the liquid drops on my skin during chemotherapy, which will make my skin bad. My mother was also implanted during chemotherapy.
