In which war did nurse anesthetists begin to play a vital role in anesthesia delivery via open drop ether technique?

• A. World War I
• B. Civil War
• C. Korean War
• D. Gulf War

Answer: (B)

The event tests when nurse anesthetists first took on a central role in delivering anesthesia using the open‑drop ether method. In the Civil War, the sheer volume of surgeries to treat battlefield injuries created a demand for rapid, scalable anesthesia. Nurses increasingly assisted or led the administration of anesthesia under surgeon supervision, and the open‑drop ether technique—where ether vapor was delivered by a drop or via a simple gauze setup—was a common, hands‑on method at that time. This era marked the beginning of nurses routinely providing anesthesia in many cases, laying the foundation for the nurse anesthetist role.

World War I and later conflicts did not feature that same early reliance on nurse‑driven open‑drop ether delivery; by then anesthesia practice had evolved with different techniques and more physician‑centered administration, and the open‑drop approach had fallen out of clinical use.
