A catheter is a flexible tube that is inserted into the body for medical purposes, typically to drain fluids, deliver medication, or assist with bodily functions. Catheters are used in a variety of medical procedures and conditions. There are different types of catheters, depending on their purpose and the body part they are intended to access.
Here are some common types of catheters:
- Urinary Catheters:
- Indwelling catheter (Foley catheter): A catheter that is inserted into the bladder to drain urine continuously. It is typically used for people who cannot urinate on their own due to medical conditions or during surgery.
- Intermittent catheter (Straight catheter): A catheter that is inserted into the bladder to drain urine but is removed after use. It is typically used for individuals with temporary or chronic urinary retention.
- Suprapubic catheter: A catheter that is inserted directly into the bladder through the abdomen, used for people who cannot use a traditional urinary catheter.
- Intravenous (IV) Catheters:
- These are inserted into veins to administer fluids, medications, or nutrients. They are often used in hospital settings for patients who need fluids or medications over an extended period of time.
- Cardiac Catheters:
- Used in procedures related to the heart, such as cardiac catheterization. This procedure involves inserting a catheter into a blood vessel, usually in the groin or wrist, to check for heart disease or to perform treatments like angioplasty.
- Epidural Catheters:
- These are placed in the space around the spinal cord to administer pain relief medications, commonly used during labor or major surgeries.
- Arterial Catheters:
- Inserted into arteries to monitor blood pressure continuously or to take blood samples for testing. They are commonly used in critical care settings.
Catheters can vary in size, material (such as silicone, latex, or plastic), and length, depending on the type of procedure and the needs of the patient.
Inserting and managing a catheter requires care to prevent infection, especially in the case of indwelling catheters. Catheter-associated urinary tract infections (CAUTIs) are a common concern in patients with indwelling urinary catheters, and medical professionals take steps to minimize the risk of such infections.
