Central venous catheter has become principal medical device during the administration of chemotherapy and blood transfusions

 

Central Venous Catheter (CVC) is a type of catheter that has its own pump. The pump enables the catheter to travel through a small opening into the body. Since the catheter is hollow, blood flow is facilitated; therefore, there are more options as far as types of applications go. Some of the most common applications of the Central Venous Catheter are to pump fluids such as medications and other treatment solutions through the body. For this reason, the tip of a standard CVC has a very small opening that is not difficult to manufacture. A skilled technician can use the appropriate tools to make a balloon catheter similar to those used for vacuuming or cleaning an eye. The resulting product has a small diameter and is often filled with saline solution.

When performing these types of applications, a professional will also use a narrow vacuum tube to guide the tubing through the patient's body. In order to do so, the physician must know wherein the patient's body is intending the central venous catheter to be inserted. Although the medical community uses different terms for these applications, in general, the insertion is referred to as a parenteral exchange. The exact method of inserting this type of catheter is referred to as the entry site of entry. The tube is guided into the subcutaneous space by means of a flexible nylon sleeve. The purpose of this procedure is for the doctor to monitor the activity of the heart and to determine whether medication is needed or not.

Furthermore, there are some specific procedures when the central venous catheter is inserted into the inferior vena cava. The reasons for these procedures vary but usually involve the need to provide relief from a specific symptom such as leg cramps. The tube is first guided through the right colon and then through the left upper segment. If there are blockages, the doctor may decide to enter through the right upper segment and remove the blockage before entering through the left lower segment. This method is called the superior vena cava catheter inserted. The commonest use of a central venous catheter involves the treatment of Rheumatoid Arthritis. The most common application of the central venous catheter is to provide for the administration of IV fluids. When the patient is experiencing a moderate amount of pain, a patient may require the use of a central venous catheter for approximately fifteen minutes at a time. The patient regains normal activity soon after the procedure. There have been few reports of complications with the use of a Central Venous Catheter in patients with severe Rheumatic Disease.

There are two types of catheter options that can be used in the treatment of Rheumatic Disease. These are the unidirectional catheter and the venicular catheter tip site placement. With the unidirectional catheter, a physician will place the catheter tip on the inferior vena cava for venicular placement. In this manner, the blood is drawn in one direction by gravity and then directed away from the heart by a pump. In the case of a central venous catheter, a small but powerful needleless connector can be used to insert the catheter tip into the central vein. The process of inserting the catheter into the body is similar to that of placing conventional compression hosiery into the leg. A catheter is placed into a very shallow vein that is first inflated with saline solution. The needleless connector is then inserted into the center of the hole created by the catheter bulb.
