In medicine, venipuncture or venepuncture is the process of obtaining intravenous access for the purpose of venous blood sampling (also called phlebotomy) or intravenous therapy. In healthcare, this procedure is performed by medical laboratory scientists , medical practitioners , some EMTs , paramedics , phlebotomists , dialysis technicians ...
Extravasation is the leakage of intravenously (IV) infused, and potentially damaging, medications into the extravascular tissue around the site of infusion. The leakage can occur through brittle veins in the elderly, through previous venipuncture access, or through direct leakage from wrongly positioned venous access devices.
Complications of venous cutdown include cellulitis, hematoma, phlebitis, perforation of the posterior wall of the vein, venous thrombosis and nerve and arterial transection. This procedure can result in damage to the saphenous nerve due to its intimate path with the great saphenous vein, resulting in loss of cutaneous sensation in the medial leg.
Collapsed veins are a common injury that results from repeated use of intravenous injections. They can result from intravenous chemotherapy [ 1 ] [ 2 ] or when injection conditions are less than ideal, such as in the context of drug abuse .
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.
The most common complications are: catheter blockage (7.4%), and catheter-related infection (5.6%). Other complications are: malpositioning of the catheter, venous thrombosis, catheter leak or dislodgement. [3] The common carotid artery may be injured during the puncture of the internal jugular vein as the artery lies close to the vein.
The most common complication is a hemorrhage, or bleeding, of the puncture site and can be especially dangerous when the fetus is younger than 21 weeks. [17] The risk of hemorrhage is greater if the fetus has a defect that affects its platelets. A transfusion of donor platelets is usually done in such cases to reduce the risk of bleeding.
Chronic venous insufficiency (CVI) is a medical condition characterized by blood pooling in the veins, leading to increased pressure and strain on the vein walls. [1] The most common cause of CVI is superficial venous reflux, which often results in the formation of varicose veins, a treatable condition. [2]
