Healthcare providers may use a number of different techniques in order to improve the chances of successful access. Some techniques include using a tourniquet, tapping over the vein, warming the area to dilate the vein, or using an ultrasound to directly visualize the target vein. Near-infrared illumination devices can also be used to help ...
The insertion of a plastic cannula and withdrawal of the needle was introduced as a technique in 1945. [11] The first disposable version to be marketed was the Angiocath, first sold in 1964. In the 1970s and 1980s, the use of plastic cannulas became routine, and their insertion was more frequently delegated to nursing staff. [12]
Scars at the base of the neck indicate the insertion point into the left jugular vein. The following are the major indications for the use of central venous catheters: [ 3 ] Difficult peripheral venous access – central venous catheters may be placed when it is difficult to gain or maintain venous access peripherally (e.g. obesity, scarred ...
A peripherally inserted central catheter (PICC or PICC line), also called a percutaneous indwelling central catheter or longline, [1] is a form of intravenous access that can be used for a prolonged period of time (e.g., for long chemotherapy regimens, extended antibiotic therapy, or total parenteral nutrition) or for administration of substances that should not be done peripherally (e.g ...
Catheter access, sometimes called a CVC (central venous catheter), consists of a plastic catheter with two lumens (or occasionally two separate catheters) which is inserted into a large vein (usually the vena cava, via the internal jugular vein or the femoral vein) to allow large flows of blood to be withdrawn from one lumen, to enter the dialysis circuit, and to be returned via the other lumen.
Intravenous therapy (abbreviated as IV therapy) is a medical technique that administers fluids, medications and nutrients directly into a person's vein.The intravenous route of administration is commonly used for rehydration or to provide nutrients for those who cannot, or will not—due to reduced mental states or otherwise—consume food or water by mouth.
Venous cutdown is an emergency procedure in which the vein is exposed surgically and then a cannula is inserted into the vein under direct vision. It is used for venous access in cases of trauma, and hypovolemic shock when the use of a peripheral venous catheter is either difficult or impossible.
The insertion of a central Groshong line is usually done under local anesthetic by an interventional anaesthesiologist, interventional radiologist or surgeon. Throughout the procedure, ultrasound and X-rays may be used to confirm placement. When a central venous catheter is inserted, a chest radiologic examination is usually performed to ...
