Notes on Meaning
- The core meaning of "paracentesis" is the puncture and drainage of fluid from a body cavity. While it most commonly refers to the abdomen (paracentesis of the belly), the prefix "para-" means "beside" or "near," and "-centesis" means "puncture." In broader, less common usage, it could theoretically refer to puncture near a cavity, but its practical application is overwhelmingly specific to abdominal fluid removal.
