perfusion

Often used in conjunction with perfusion (e.g., 'perfusion intraveineuse'), meaning 'intravenous.'

The fluid often used in a perfusion, similar to 'saline solution' or 'IV fluid.'

The English term for a 'goutte à goutte,' which is a method of administering a perfusion.

Sounds very similar to 'perfusion' but is the verb form.

While 'perfusion' is the act, 'perfuser' is the action of performing the act.

Le médecin va perfuser le patient. (The doctor will perfuse the patient.)

Both involve introducing a fluid, but the method and context differ.

Perfusion specifically refers to the act of injecting into a blood vessel or organ, often with a pump. Infusion is a broader term that can include gravity-fed drips and can also refer to steeping something (like tea).

Une infusion de camomille. (A chamomile infusion.) / L'infusion intraveineuse. (The intravenous infusion.)

Both involve introducing substances into the body.

Perfusion implies a continuous or sustained delivery of fluid into a vessel or organ. Injection typically refers to a single, often rapid, shot of a substance.

Une injection de vaccin. (A vaccine injection.)

Both involve introducing fluids into the bloodstream.

Perfusion is about delivering fluid to an organ or tissue to maintain its function. Transfusion specifically refers to transferring blood or blood components from one person to another.

Une transfusion sanguine. (A blood transfusion.)

Can be used to describe a method of fluid delivery that looks similar to perfusion.

Literally 'drop by drop,' this refers to an IV drip. While a perfusion can be administered via 'goutte à goutte,' 'perfusion' is the broader medical term for the act itself.

Le patient est sous goutte à goutte. (The patient is on a drip.)
