Use of medium-length intravenous catheters in neonatal units

Vascular catheters

Central and peripheral venous and arterial cannulas are known under this name. They are used for the following purposes: to administer drugs through the bloodstream; for blood collection. These devices are hollow, thin tubes pointed at one side that are inserted into a blood vessel in the arm, neck, or head area. On the other hand, a system with medications is connected to them. This is done to avoid frequent puncture of the veins, which leads to inflammation and blood clots. The following types of catheters exist:

• central peripheral intravenous, which is injected into the vessels of the arms;
• tunnel for large vessels, for example, the vena cava;
• subcutaneous venous, which are inserted under the skin in the chest area.

Intravenous catheter with additional INTEGRAL port

An intravenous catheter with an additional port is intended for long-term (up to 3 days) administration of drugs without additional puncture into the patient’s peripheral veins. Made of fluorinated ethylene propylene (fluoropolymer) with Teflon coating, it is elastic, optimal rigidity prevents the formation of creases, transparent, non-toxic, has a high degree of biocompatibility, has pyrogen-free, non-toxic, and since it comes into direct contact with blood - biocompatible and hypoallergenic properties.

The sharp and elastic needle is made of high-quality durable medical steel and is resistant to various chemicals. Slippery surface due to the low surface tension of the polymer, optimal rigidity prevents the formation of creases.

Advantages:

• the possibility of without a needle bolus (intermittent) administration of drugs without interrupting the intravenous infusion.
• transparent chamber allows you to verify the success of venipuncture
• low coefficient of friction reduces pain during catheter insertion
• the catheter fits tightly around the needle and minimally injures tissue when inserted into a vein
• the minimum distance from the end of the catheter to the needle cut and a decrease in the thickness of the catheter wall towards the distal end facilitates vein puncture
• the presence of radiopaque stripes provides effective control over their location in the vein.
• The presence of wings allows not only to securely fix the catheter to the skin, but also reduces the risk of bacterial contamination, since they do not allow direct contact between the back of the catheter plug and the skin.
• The injection port cover opens and closes effortlessly.
• the plug has an internal thread, which ensures a tight fit of the plug to the catheter and completely eliminates contact with the patient’s blood
• The color coding corresponds to the catheter size designation.
• sterile

Types of cavity catheters by area of ​​application

There are many different types of abdominal catheters.
For the nasal and oral cavities, aspiration catheters with a Kapkon or Vakon port are used. They can also be used to suction the trachea and bronchi. Epidural anesthesia is performed using epidural catheters. If it is not possible to excrete urine naturally, which necessitates long-term drainage of the bladder, Malekot catheters are used. They remove urine through an external fistula on the anterior abdominal wall. However, Foley and Nelaton catheters are most often used in medical practice.

Placement and care of an intravenous catheter

Central vein catheterization is performed using one of three techniques: using a catheter on a needle, similar to the installation of a peripheral catheter, passing the catheter through a needle of a larger diameter, and also using the Seldinger method (through a self-destructive guidewire).
The insertion of an intravenous catheter or port system is performed under aseptic conditions by experienced medical personnel. Local anesthesia or general anesthesia is used. Unlike a port system, an intravenous catheter can become a conduit for infection to enter the body. To avoid this, you should strictly follow the rules for using and caring for the catheter as prescribed by your doctor.

Foley catheters

These products are primarily used in the treatment of diseases of the genitourinary system in men and women for the following procedures:

• urine excretion;
• administering medications;
• organ washing;
• drainage of organs.

Visually, this device looks like a tube, at one end of which there are two or three branches, and at the other end a balloon is attached to hold the product in the bladder. The catheter can be used for a long time. In a two-way modification, one channel is used to drain urine, the second is used to fill the balloon. The three-way one has an additional channel for administering drugs. There are options for women (shorter) and for children (smaller diameter). The products are made from latex coated with silicone and sold in sterile packaging.

Nelaton catheters

This type of product is used for short-term drainage of the bladder and urethra; their main difference from the devices described above is the absence of a balloon.
The design is quite simple: the main part is a hollow tube with a semicircular tip at one end and a urine collection connector at the other. Male versions may have a slightly curved Tiemann tip, which greatly facilitates their insertion. Catheterization in men is more difficult, so it is important that the device can be guided without injury.

The devices vary in size, with the longest ones being for men. The size is determined using a special Charrière scale; for clarity, the connectors are marked with a certain color. The products are made from polyvinyl chloride or polyurethane; they feel quite hard to the touch, but when exposed to body heat they become softer. Due to the lack of fixing elements, their long-term use is not intended. More expensive models are coated with a lubricant to facilitate insertion or an antibacterial layer.

Fixation of catheters

Catheters should always be secured to the body or organ.
They can be attached to the skin with adhesive tape, suture material or special fasteners. Some cavity non-vascular catheters have a special design that allows them to be fixed in the organ independently: an inflatable balloon, a loop system, Malecot, Petzer systems, etc. Today, the Pigtail system is becoming increasingly common: during installation, the tip of the catheter is straightened and is located in a special guide. When the guidewire is removed, the tip curls like a pig's tail and prevents the device from falling out. The modern medical product market offers a large selection of catheters for various purposes. There are more expensive models, with an improved design, and there are basic ones, simpler, but no less effective. The current range of these products is presented in the Deznet LLC store at affordable prices.
