catéteres

Catéteres are medical devices that are typically long, thin, flexible tubes inserted into the body. Their primary function is to introduce fluids into or remove fluids from the body, or to access and treat diseased organs. Catheters can be made from a variety of materials, including silicone, polyurethane, and PVC, and their design varies depending on their intended use.

There are numerous types of catheters, categorized by their application. Urinary catheters are used to drain the bladder, commonly for patients who have difficulty urinating due to medical conditions or surgery. Cardiovascular catheters are inserted into blood vessels to diagnose and treat heart and vascular diseases. These can be used for procedures like angioplasty or stent placement. Intravenous (IV) catheters are inserted into a vein to administer fluids, medications, or blood products directly into the bloodstream. Other specialized catheters exist for procedures in areas such as neurosurgery, urology, and gastroenterology.

The insertion of a catheter is a medical procedure that should only be performed by trained healthcare professionals. While generally safe, potential risks include infection, bleeding, or damage to surrounding tissues. Proper sterile technique is crucial to minimize the risk of complications. The duration of catheter use can range from a few hours to several months, depending on the patient's medical needs. Regular monitoring and maintenance are essential for safe and effective catheterization.
