katétereket

Katétereket, or catheters, are thin, flexible tubes used in medicine to drain fluid from the body or deliver medication. They are typically made of medical-grade silicone, rubber, or plastic. The insertion of a catheter is known as catheterization.

There are various types of catheters used for different purposes. Urinary catheters are commonly used to drain urine from the bladder when a person cannot do so naturally, such as in cases of urinary retention, surgery, or incontinence. These can be inserted through the urethra or surgically placed through the abdominal wall.

Other types of catheters include intravenous (IV) catheters, which are inserted into a vein to administer fluids, medications, or nutrients directly into the bloodstream. Cardiac catheters are used in procedures like angioplasty to diagnose and treat heart conditions. Gastrostomy tubes (G-tubes) are placed into the stomach through the abdomen to provide nutrition. Dialysis catheters are used for kidney dialysis.

The use of catheters requires sterile technique to prevent infection. Potential risks associated with catheterization include urinary tract infections, discomfort, and damage to the tissues. The specific type of catheter and the procedure for its insertion and maintenance depend on the medical condition being treated and the patient's individual needs.
