Intravenous research focuses on the administration of drugs, fluids, or other substances directly into the bloodstream through a vein. This method allows for rapid and efficient delivery of medications or nutrients, making it a common route of administration in healthcare settings. Researchers in this area may study the efficacy, safety, and optimization of intravenous therapies, as well as explore new techniques and technologies for intravenous delivery. Additionally, they may investigate the impact of intravenous treatments on patient outcomes and develop guidelines for best practices in intravenous administration.
