When did Intravenous therapy start?

Intravenous (IV) therapy began in the 19th century, with significant advancements occurring in the early 1900s. The first recorded use of IV therapy was by Dr. Thomas Latta in 1832, who administered saline solutions to patients suffering from cholera. However, it wasn't until the 1930s that the technique became more standardized and widely used in medical practice, particularly with the introduction of more refined equipment and techniques.
