Why is the central line and related risks needed?


The central chain is the type of catheter, which is placed in a large vein, which allows you to obtain several fluids IV and blood.Compared to a typical line IV, the central line is greater, it can stay in its longer place,It can provide a greater amount of fluid and facilitates the blood drawing

The center line can also be used to measure the status of theLiquid volume, and to help determine if the patient is dehydrated or received an adequate amount of liquid to withstand the functions of the body.

A line of PICC , IV-Access type IV, which can be maintained for several weeks and months, is not a central line, and does not have numerous features with this type of IV access.

Purpose of the center line

The center line can be published for several reasons.The center line can have up to five lumens that are ports in which liquid can be applied, can remove or measure the measurements.

If the patient needs to resuscitate the liquid, it means that a significant amount of intravenous fluids must be provided, the center line can be placed to provide Fluid flow faster.

Central lines can also be used for blood drawing.In some cases, two of the lumens can be used on the center line to perform dialysis, with a lumen used to take blood from the vascular system, and the other authorization used to return the blood dialyzed in the body.

For patients who require frequent blood patterns, which should be sent to the laboratory, the center line allows you to extract blood that does not repeat the patient ‘stick’.

A function that is unique for some central lines is the ability to measure central venous pressure.This measurement provides a health equipment, an understanding of the amount of fluid in the vascular system, and if the patient received too much or very little liquid.

If the center line is a Swan-Ganz type catheter, you can also get the pulmonary wedge, which can be indicated indirectly as the left Atrium of heart functions.For patients who have serious heart problems or recent cardiac operations , this information can be extremely valuable.

The center line is also suitable when long-term therapy is expected, such as the weeks of antibiotics IV, or if medications are needed Caustics, can not be provided through the IV standard, for example,For chemotherapy .

Insertion of the center line

To insert a central line, the patient must be flat, and the body area where the center line is inserted, subjected to insertion.

The most common veins used to place the center line are internal ulcers on the neck, Vienna subclowan near the clavicle and femoral veins in the groin.

The patient is covered, as a rule, from the head towards the nose, with a sterile curtain. The cutter is a sterile sheet of paper with a hole in it to the individual room of the center of access to the vein.

sterile drapes is designed to help reduce the risk of infection, and studies have shown that they cover the entire body, and not just an area where the central line will be placed is the best practice for the prevention of the infection .

After the patient is sent, the area of the skin is cleaned. If the patient is not sleeping, the area of the skin can also be surprised with local anesthesia .

The use of sterile technology, a hollow catheter is inserted into the vein, as a general rule, using ultrasound to find the corresponding blood vessel.Then, the catheter is seated in place, or the adhesive device is used to keep the catheter at the insertion place.

The region is cleaned again with an antiseptic, and the sterile bandage is located in the Insertion platform, with accessible lumens.The placement of the catheter must be confirmed using the X-ray beam before the center line can be used to avoid accidental use of the tissue medications or an incorrect blood vessel.

In some cases, the catheter can be in the right container, but it needs a slight adjustment, because the catheter is too far in the container, or not enough.

Risks of the center line

There are risks associated with the insertion of the center line, which must be weighed against the patient’s need on the line. The infection is the greatest risk.

Center line associated with a heated infection

One of the risks of the central placement and the use of the line Central is the center line connected blood infection (CLABSI).To help implement infections , the best standardized practices have been implemented.

These methods include planned changes of sterile bandages, using sterile drapes with a full body during the placement of the line, eliminating a line, as soon as it is no longer necessary, and only insert the central lines,They are absolutely necessary.

The central lines are usually placed on the waist when it can minimize the risk of infection. The sites of the femoral veins are associated with a higher rate of infection.

The appeal, placed above the insertion site, is usually transparent, which allows the health team to verify in signs of infection , Not exposing the air Insert the site more than absolutely necessary.

Other risks

Other risks include pneumothorax (rolled lung), especially if the Central The line is published in the Vienna Subklav. It is treated with a chest tube if necessary.

During the insertion of some types of central lines, the heart can be an irritable process when the line moves through the blood vessels Near the heart causing a change in the rhythm of the heart.In general, this is allowed with the proper placement of the line, but medications may be required for some rare people.

One of the final complications of the central lines is an aerial embolism, a condition in which the air enters the vascular system and begins to Pass through the body.This condition, which is very serious, is also very rare and is practically avoiding.

Word get Information Meds

The center line is extremely useful when the patient is sick, but it is not without risks.For many patients, the advantage does not have multiple ‘sticks’ for blood patterns and reliable IV access availability, rather than the risks represented by this type of access.

For some patients, the center line makes hospitalization more direct, while others are not concerned, trusting and prefer to avoid possible complications that can bring a central line.

Frequently asked questions

  • Peripheral inserted central catheter (PICC) The lines are placed in hand, not chest, neck or groin.They are a very long type of catheter, which thread through Vienna in hand. The center line can stay longer than the PICC line provides a greater volume of fluids and allows you to extract blood.

  • The center line can remain in place for several days, weeks or months, there are no complications as an infection or blocking.

  • After the center line is no longer necessary, the person is placed on the back and it is found so that your head is slightly under your heart and legs.The catheter is removed, they can be asked to breathe a lot, keeping them their hand from the nose in front of the catheter. A person carrying out the elimination procedure during this time presses the pressure on the site.

  • internal jugular vein on the neck, the subminanous vein near the clavicle, and the femoral vein in the groin is common areas for the center line.
