Ultrasound guided peripheral IVs and external jugular access would probably be the next “go to options” in these patients. Ultrasound guidance has been a great addition in these patients. In stable patients, however, this may be a less desirable. Many providers have resorted to using IO access, particularly in critically ill patients due to speed of establishing access. This often creates delays in patient care, increases ED length of stay, and uses up ED staff that have other patients to care for. Patients are transported to the radiology department for PICC line insertion.Background: We have all taken care of patients in whom IV access is difficult due to a multitude of reasons including repeated prior IV access, advanced vascular disease and shock. They are most often inserted into longer stay patients if it becomes difficult to find a suitable IV site. They take longer to insert than other central lines and are not generally inserted when the patient is acutely ill. They are generally not used for CVP monitoring. PICC catheters can be used to give drugs that require a central line. Thus, the catheter is called a Peripherally Inserted Central Catheter. The catheter is very long and thin, and is advanced until the tip of the catheter is located in a large central vein. A PICC line is an IV that is inserted peripherally, usually in the bend of the arm. The introducer is often called the "Cordis" this was the Trade name for the first product ever produced.Īnother type of Central Venous Catheter is a PICC line. This " introducer" can be used as an additional central line regardless of whether a catheter is inserted through the centre. Multi-lumen catheters are often inserted through a short central line with a wider inner diameter. Multi-lumen catheters allow us to run several different infusion with only one access site (Image 2).
A double lumen catheter has 2 lumens while a triple lumen catheter has 3. A different intravenous infusion can be connected to each lumen, and the fluid will usually exit at a slightly different point along the catheter. A multi-lumen catheter is a single catheter with more than one internal channel (called a lumen). Many of the Central Venous Catheters used are " multi-lumen catheters". A low oxygen level in the venous blood indicates that the patient's cardiac output is too low.
This is known as a venous blood gas sample. A large Central Venous Catheter makes it easy to give fluid rapidly when required.Ĭentral venous catheters can also be used to measure the amount of oxygen in the blood that is returning to the heart. CVP measurements help us to determine the amount of IV fluid a patient needs. This pressure is known as the Central Venous Pressure or CVP. They can be connected to a pressure monitoring system and used to measure the pressure inside the right side of the heart. Most critically ill patients will have a Central Venous Catheter.Ĭentral Venous Catheters can be used for other reasons. Drugs that are used to treat low blood pressure, chemotherapy agents and solutions with high concentrations of glucose (sugar) are examples of drugs that need to be administered through a Central Vein. Administration of these drugs into large central veins allows the drugs to be rapidly diluted by the large blood volume. Many of the drugs used during critical illness are irritating or harmful to small blood vessels. The most common sites are: subclavian (upper chest), jugular (neck) or femoral (groin). These catheters are inserted percutaneously ("cutaneous" means skin, "per" means through). A "Central Venous Catheter" or Central IV is an intravenous catheter that is inserted into a large vein close to the right side of the heart.
