IVkatetri

IVkatetri, commonly known as an intravenous catheter, is a flexible tube inserted into a vein to provide venous access for delivering fluids, medications, nutrition, or for taking blood samples. It enables rapid administration of therapies and ongoing monitoring of a patient’s status.

There are several types of IV catheters. Peripheral venous catheters are short tubes placed in a hand or arm vein for routine therapies. Midline catheters are longer than peripheral lines but do not reach central veins. Peripherally inserted central catheters (PICC) extend from a peripheral vein to reach larger central veins. Central venous catheters include lines placed in central veins and may be tunneled or implanted. Implanted ports provide long-term access and are accessed with a special needle. Each type has different indications, dwell times, and care requirements.

Insertion is performed by trained healthcare professionals under sterile conditions, often with local anesthesia. The choice of catheter depends on the planned duration of therapy, the type of medication, and patient factors. Care and maintenance involve regular site inspection, securement, and dressing changes, as well as periodic flushing to keep the lumen open according to protocol.

Complications can include infection at the insertion site or bloodstream, phlebitis, infiltration or extravasation, catheter occlusion, thrombosis, and rare mechanical issues. Removal is indicated when therapy ends, the device is no longer functioning, or complications arise.
