katétry

Katétry, also known as a catheter, is a flexible, hollow tube used to deliver fluids, medications, or to drain bodily fluids. It is commonly used in medical procedures to access the urinary tract, gastrointestinal tract, or cardiovascular system. Katétry can be inserted through various body orifices, such as the urethra, rectum, or a vein, depending on the intended use.

There are several types of katétry, including:

1. Urinary katétry: Used to drain urine from the bladder, often in cases of urinary retention or urinary tract infections.

2. Gastrostomy katétry: Inserted into the stomach to provide nutritional support or to drain stomach contents.

3. Central venous katétry: Placed in a large vein, typically in the neck or chest, to deliver medications, fluids, or to monitor blood pressure.

4. Arterial katétry: Inserted into an artery to measure blood pressure or to deliver medications.

Katétry are typically made of flexible materials such as silicone or polyurethane, and they come in various sizes and shapes to suit different medical needs. They are often inserted under local or general anesthesia, depending on the procedure. After use, katétry are removed and disposed of according to medical waste guidelines.

Katétry play a crucial role in modern medicine, enabling healthcare professionals to provide effective treatment and care for patients with various medical conditions. However, like any medical device, katétry can pose risks, including infection, bleeding, and complications related to the insertion site. Therefore, their use is carefully monitored and managed by healthcare providers.
