If the carotid is accidentally cannulated and a catheter is inserted into the artery, the catheter should be left in place and a vascular surgeon should be notified because removing it can be fatal. However, it has a reported incidence of 0.5–11% when an anatomical approach is used. This occurs at a rate of approximately 1% when ultrasound guidance is used. Accidental cannulation of the carotid artery is a potential complication of placing a central line in the internal jugular vein. Fortunately, the incidence of these events is exceedingly rare, especially when lines are placed with ultrasound guidance. Perforation of vasculature by a catheter is a feared and potentially life-threatening complication of central lines. Instead, bedside ultrasound is a superior method of detection in those too ill to obtain upright imaging. Radiographs obtained in the supine position fail to detect 25–50% of pneumothoraces. Of course, this is not always possible, particularly in critically ill patients in the intensive care unit.

An upright chest x-ray is preferred because free air will migrate to the apex of the lung, where it is easily visualized. If a pneumothorax is suspected, an upright chest x-ray should be obtained. The National Institute for Health and Clinical Excellence (UK) and other medical organizations recommend the routine use of ultrasonography to minimize complications. For experienced clinicians, the incidence of pneumothorax is about 1.5–3.1%. In the case of catheterization of the internal jugular vein, the risk of pneumothorax is minimized by the use of ultrasound guidance. The incidence of pneumothorax is highest with subclavian vein catheterization due to its anatomic proximity to the apex of the lung. The benefit expected from their use should outweigh the risk of those complications. However, there are risks and complications associated with the placement of central lines, which are addressed below.Ĭentral line insertion may cause several complications. Relative contraindications include: coagulopathy, trauma or local infection at the placement site, or suspected proximal vascular injury. There are no absolute contraindications to the use of central venous catheters. pulmonary artery catheterization) require central venous access. Specialized treatment – interventions such as hemodialysis, plasmapheresis, transvenous cardiac pacing, and invasive hemodynamic monitoring (e.g.Prolonged intravenous therapies – parenteral medications that must be delivered for extended periods of time (more than a few days) such as long-term parenteral nutrition, or intravenous antibiotics are administered through a central line.Additionally, catheters with multiple lumens can facilitate the delivery of several parenteral medications simultaneously. Delivery of certain medications or fluids – medications such as vasopressors (e.g., norepinephrine, vasopressin, phenylephrine etc.), chemotherapeutic agents, or hypertonic solutions are damaging to peripheral veins and often require placement of a central line.obesity, scarred veins from prior cannulations, agitated patient). Difficult peripheral venous access – central venous catheters may be placed when it is difficult to gain or maintain venous access peripherally (e.g.The following are the major indications for the use of central venous catheters: Scars at the base of the neck indicate the insertion point into the left jugular vein. Additional fasteners, and corresponding surgical threadĪ dialysis two-lumen catheter inserted on the person's left side.Introducer needle (here 18 Ga) on syringe with saline to detect backflow of blood upon vein penetration.Medical uses Central line equipment, in order of typical usage: The catheters used are commonly 15–30 cm in length, made of silicone or polyurethane, and have single or multiple lumens for infusion. These catheters are commonly placed in veins in the neck ( internal jugular vein), chest ( subclavian vein or axillary vein), groin ( femoral vein), or through veins in the arms (also known as a PICC line, or peripherally inserted central catheters).Ĭentral lines are used to administer medication or fluids that are unable to be taken by mouth or would harm a smaller peripheral vein, obtain blood tests (specifically the "central venous oxygen saturation"), administer fluid or blood products for large volume resuscitation, and measure central venous pressure. Placement of larger catheters in more centrally located veins is often needed in critically ill patients, or in those requiring prolonged intravenous therapies, for more reliable vascular access. A central venous catheter ( CVC), also known as a central line (c-line), central venous line, or central venous access catheter, is a catheter placed into a large vein.
