arteriekanyle

An arteriekanyle, also known as an arterial line or intra-arterial catheter, is a thin plastic tube inserted into an artery. This device is primarily used for continuous monitoring of arterial blood pressure. It allows for real-time measurement of systolic, diastolic, and mean arterial pressure, which is crucial in critically ill patients or those undergoing major surgery.

Beyond blood pressure monitoring, arteriekanyler are also used for frequent arterial blood gas sampling without the need for repeated needle punctures. This provides valuable information about a patient's oxygenation, ventilation, and acid-base balance. In some cases, these lines can also be used for the withdrawal of blood for laboratory tests.

The insertion of an arteriekanyle typically occurs in a sterile environment, often in an operating room or intensive care unit. The radial artery is a common site due to its accessibility and lower risk of complications. Other potential sites include the femoral or brachial arteries. Proper placement and securement of the catheter are essential to prevent dislodgement and infection.

Complications associated with arteriekanyler, though generally rare, can include bleeding, hematoma formation, infection, thrombosis, and distal ischemia. Regular assessment of the insertion site and the distal circulation is important to detect and manage any potential issues. The decision to use an arteriekanyle is based on the patient's clinical condition and the need for precise hemodynamic monitoring and frequent blood sampling.
