There are several methods of vascular access used in toxicology, each with its advantages and limitations:
Peripheral Venous Access: This is the most common method and involves inserting a cannula into a peripheral vein, usually in the arm. It's quick, relatively easy, and suitable for administering most medications. Central Venous Access: Used in more severe cases, this method involves accessing a larger vein, such as the subclavian or jugular vein. It allows for the administration of larger volumes of fluid and drugs that might irritate smaller veins. Intraosseous Access: This is an alternative when venous access is difficult, especially in pediatric cases. A needle is inserted into the bone marrow, providing rapid access to the vascular system.
