Vascular access refers to a rapid, direct method of introducing or removing devices or chemicals from the bloodstream. In hemodialysis , vascular access is used to remove the patient's blood so that it can be filtered through the dialyzer .
In emergency situations when peripheral access cannot be easily achieved, such as in arrest scenarios, intraosseous methods can be used to gain rapid access to the venous system. These methods usually involve inserting an access device into the tibia or femur bones in the legs, humerus in the upper arm, or sometimes the sternum in the chest. [2 ...
A peripheral venous catheter is the most commonly used vascular access in medicine. It is given to most emergency department and surgical patients, and before some radiological imaging techniques using radiocontrast, for example. In the United States, in the 1990s, more than 25 million patients had a peripheral venous line each year. [2]
Port access requires specialized equipment and training. Ports are typically used on patients requiring periodic venous access over an extended course of therapy, then flushed regularly until surgically removed. If venous access is required on a frequent basis over a short period, a catheter having external access is more commonly used. [1]
Attempts to gain access to the subclavian vein can injure the lung coverings, potentially causing a pneumothorax. The risk of pneumothorax is 1.5 to 6% depending upon the surgeon's experience. [11] Age: If the device is put into a child, the child's growth means that the catheter becomes relatively shorter and will move towards the head.
Intraosseous devices allow quick and safe access to the vascular system for fluid and drug administration. After proper education and training, medical professionals can obtain vascular access via the IO route of administration by using one of the multiple devices that have been approved by the FDA for 24-hour use.
