Antonyms are words that are opposite in meaning to a given word. Therefore, antonyms for the phrase "Central Venous Catheterizations" could be words such as "peripheral," "superficial," or "external." Instead of a central location, these words imply a more peripheral or surface-level placement. Other antonyms might include "remove," "extract," or "withdraw," which would suggest the catheterization process being reversed rather than initiated. Additionally, antonyms for specific aspects of the central venous catheterization procedure might include words such as "complications," "errors," or "compromises," which would suggest a less than optimal outcome.
