Catheterized

Catheterized describes a person who has a catheter in place. Catheterization is the process of inserting a flexible tube, or catheter, into a body cavity or vessel to drain fluids, deliver medications, or obtain measurements. The most common use is urinary catheterization, which channels urine from the bladder through the urethra or via a surgically created route.

Urinary catheterization can be intermittent or indwelling. Intermittent catheterization involves periodic insertion and removal, often for precise urine assessment or bladder management. Indwelling or Foley catheters remain in place for a period of time and connect to a drainage bag. Suprapubic catheterization places the catheter through the abdominal wall into the bladder and may be used when urethral access is difficult or after certain surgeries.

Other catheterizations include vascular access catheters, such as peripheral or central venous catheters for medications or fluids, and arterial catheters for continuous blood pressure monitoring or blood sampling. Cardiac catheterization is a diagnostic or therapeutic procedure involving catheters threaded to the heart and coronary arteries.

Risks associated with catheterization include infection, particularly catheter-associated urinary tract infections; urethral or bladder trauma; obstruction or encrustation of the catheter; dislodgement or blockage of the line; and discomfort or bladder spasms. Proper technique emphasizes asepsis, lubrication, securement, and a closed drainage system when catheterizing urine, with removal when no longer clinically indicated. Education focuses on recognizing signs of infection or complications and seeking timely care.
