Are intravenous injection and bolus injection the same thing?

Intravenous injection and IV push are usually not the same thing; they are two commonly used clinical treatment methods. The specific analysis is as follows:

Intravenous injection refers to injecting medication directly into a vein, allowing rapid delivery through the venous system into the systemic circulation to achieve therapeutic effects. This is typically performed using a syringe and needle, and clinically divided into slow and rapid injections—slow injection generally completed over several minutes, while rapid injection can be accomplished within seconds. In contrast, an IV push (intravenous push) involves slowly administering medication into a vein via intravenous infusion, usually using an infusion set and tubing. The administration speed is relatively slower, often requiring tens of minutes or even hours to complete. Intravenous administration is a common clinical treatment method that enables drugs to take effect quickly, and is particularly suitable for critically ill patients requiring emergency care, or those unable to take oral medications or receive subcutaneous or intramuscular injections. Both intravenous injection and IV push must be performed by trained medical professionals to prevent accidental injury.

After receiving an intravenous injection or IV push, patients should monitor their own condition. If an allergic reaction occurs, they should promptly cooperate with medical staff for appropriate management.
