perioperative
周術期
解説 Definition
医学用語で、手術の前・中・後を含む周術期の、という意味の形容詞です。perioperative care や perioperative management のように、手術を中心とした一連の期間に関わるものを表します。
Perioperative describes the time around a surgical operation, including before, during, and after the surgery. It is mainly used in medicine to talk about care, risks, or treatment connected to an operation.
覚え方のコツ Memory Tip
まず operative を見て「手術・処置に関わる」と押さえ、そこに peri- が付くと「その周辺をぐるっと含む」と考えると覚えやすいです。つまり perioperative は手術そのものだけでなく、preoperative（術前）・intraoperative（術中）・postoperative（術後）をまとめて包む語。医療文脈では perioperative care, perioperative management の形で頻出し、「手術の前後を含む全体管理」という場面ごと覚えると定着します。
Think of `peri-` as in `perimeter`: around something. `Operative` is about an operation, so `perioperative` means the time and care around surgery, not only during it. Remember common phrases like `perioperative care` and `perioperative management`.
例文

perioperative の語源・成り立ち Etymology
perioperativeはギリシャ語 peri-「周囲」と、ラテン語 opus「仕事」に連なる operative から成る。『手術のまわり』という分解どおり、術前・術中・術後をまたぐ語だと見えてくる。関連語は perimeter, operate。
perioperative is built from peri- and operative. Peri- comes from Greek and means "around," while operative comes from Latin opus, meaning "work," through operari "to work." The word was formed to cover what happens around an operation as a whole, and its roots can also be seen in words like perimeter and operate.
