Translation guide
In Japanese, the concept of 'anesthetic' is expressed through different words depending on whether it refers to general anesthesia (unconsciousness), local anesthesia (numbing a specific area), or the medical specialty. The most common and general term is 麻酔 (masui), which can refer to both the state and the substance.
The broadest and most common way to refer to an anesthetic substance or the state of anesthesia, used in medical and everyday contexts.
This is the most general term for 'anesthetic' or 'anesthesia'. It can refer to the substance itself or the induced state. Commonly used in compounds like 麻酔薬 (anesthetic drug) and 麻酔科 (anesthesiology department).
We will administer anesthetic before the surgery.
The anesthetic wore off and I started feeling pain.
Specifically refers to an anesthetic drug or agent. More precise than 麻酔 when emphasizing the pharmaceutical substance.
This anesthetic drug has few side effects.
When referring to anesthetics that cause loss of consciousness for major surgery.
When referring to anesthetics that numb only a part of the body, such as at the dentist.
Referring to the field of anesthesiology or an anesthesiologist.
麻薬 (mayaku) means 'narcotic' or 'illegal drug', not 'anesthetic'. Using 麻薬 when you mean anesthetic could cause serious misunderstanding.
In casual contexts, Japanese speakers often just say 麻酔 (masui) to refer to the anesthetic they received, without specifying general or local. For example, at the dentist: 「麻酔がまだ効いてる」(The anesthetic is still working).
General anesthetic drug. More specific when referring to the agent itself.
A new general anesthetic has been developed.
The anesthesiologist adjusts the amount of anesthetic.
