Cateterelor

Cateterelor is a medical device used to deliver medications, fluids, or gases into the body, or to drain fluids or gases from the body. The term "cateter" is derived from the Greek word "katethes" meaning "to let down." Cateters are typically made of flexible, non-reactive materials such as silicone, latex, or polyurethane, and are available in various sizes and shapes to suit different medical needs.

Cateters are commonly used in various medical procedures, including:

1. Urinary catheterization: A urinary catheter is inserted into the urethra to drain urine from the bladder, often used in cases of urinary retention or bladder injury.

2. Central venous catheterization: A central venous catheter is inserted into a large vein, such as the subclavian or femoral vein, to deliver medications, fluids, or blood products, or to monitor central venous pressure.

3. Arterial catheterization: An arterial catheter is inserted into an artery, such as the radial or femoral artery, to monitor blood pressure, draw blood samples, or deliver medications.

4. Endoscopic procedures: Cateters are used in various endoscopic procedures, such as bronchoscopy, gastrostomy, or colonoscopy, to deliver medications, fluids, or gases, or to drain fluids or gases from the body.

Cateters are inserted using various techniques, depending on the specific medical need. In some cases, the catheter is inserted through the skin and guided to the target site using imaging techniques such as fluoroscopy or ultrasound. In other cases, the catheter is inserted through a natural orifice, such as the mouth or anus, and guided to the target site using endoscopy.

Cateters are an essential tool in modern medicine, enabling healthcare professionals to deliver medications, fluids, or gases, or to drain fluids or gases from the body, in a safe and controlled manner. However, like any medical device, cateters can also pose risks, such as infection, bleeding, or damage to surrounding tissues, and should be used with caution and under the guidance of a healthcare professional.
