A catheter inserted through the subclavian vein, internal jugular vein, or femoral vein, with the tip located in the superior or inferior vena cava.

It can be used for drug infusion and hemodynamic testing of any nature. It should not be used for high-pressure syringe pumps to inject contrast media (except for high-pressure resistant catheters).

① Assess the condition of the catheter every day, keep the catheter in a normal state, observe the infusion speed, and avoid the pipeline from being broken or falling off.

② During the infusion process, the liquid should be replaced and the tube should be sealed in a timely manner. It is strictly forbidden to leave the liquid empty, because the superior vena cava pressure is 2-4 mm water column lower than the surrounding venous pressure. It can drop to zero or negative pressure when the blood volume is insufficient or deep inhalation, which can easily allow air to enter. Air embolism or even death

③ Precautions for pulling out

④Maintenance

Wear loose clothes and avoid tight-fitting or elderly sweaters; pay attention to protecting the pipeline when moving the body; keep the skin at the puncture site clean and dry; notify the nurse immediately if the dressing curls or falls off; if pain or itching occurs at the puncture point, notify the medical staff in time. Insist on making an effective fist every day, three times a day, 30 groups at a time

It is suitable for medium and long-term intravenous treatment and can be used for drug infusion of any nature. It should not be used for injection of contrast media with high-pressure syringe pumps (except for high-pressure resistant catheters).

1. Assess the condition of the catheter every day, keep the catheter in normal condition, observe the infusion speed, and avoid the tube from being broken or falling off. Observe the skin condition for redness, swelling, bleeding, etc.

2. On the day of PICC catheter placement, the elastic bandage is applied under pressure for 4-6 hours and can be loosened without any discomfort after 6 hours. Special circumstances will depend on the situation. The arm where the catheter is placed is immobilized for 1-2 hours to prevent bleeding.

3. maintain

1. The first maintenance was carried out on the second day after the catheter was inserted, and we were instructed to perform fist clenching exercises (ten times a day, ten minutes each time, clenching for 5 seconds and loosening for two seconds) and wrist hanging exercises (five times a day, three minutes each time), which should be done every day , until extubation.

2. Patients with PICC catheters can perform general daily work, housework, and physical exercise, but they need to avoid using the arm on the side of the catheter to lift heavy objects (not exceeding 3kg), lift dumbbells, and do lifting exercises (such as badminton). Waiting for exercise

3. It is forbidden to sleep with the arm on the side where the PICC tube is inserted to prevent the arm on the side of the PICC tube from drooping for a long time and prevent edema.

4. People with PICC are advised to take a bath and shower, but not swimming or bathing. Before bathing, they can wrap it lightly with a highly absorbent towel, then wrap it tightly with plastic wrap, and tape the upper and lower edges tightly with tape. After bathing, check whether the dressing is soaked. If it gets soaked, please change the dressing in time.

5. You need to drink more water, at least 2000ml a day, to prevent thick blood from causing blood clots.

6. maintain

A closed infusion device that is completely implanted in the human body, including the catheter part with the tip located in the vena cava and the injection seat embedded under the skin.

Can be used for drug infusion of any nature, and should not be used for high-pressure syringe pumps to inject contrast media (except for high-pressure resistant catheters)

①Puncture

②Maintenance

Daily life, work and housework will not be affected

Avoid lifting heavy objects and excessive activities on the same side

Avoid large-scale shoulder and chest abduction movements, such as body upwards, playing ball, swimming, etc.

Avoid gravity impact, prevent the port from twisting, and move the arm on the same side more

If there is edema or pain in the shoulder, neck or upper limb on the same side, you should be alert to venous thrombosis and return to the hospital for review in a timely manner. Check chest X-ray and B-ultrasound regularly.

The infusion port should be removed promptly when it is no longer in use.
