護理師準備對 6 個月大的嬰兒進行肌肉注射。哪部位是首選？
A nurse is preparing to administer an intramuscular injection to a 6-month-old infant. Which site is preferred?
- AVastus lateralis site✓ 正解股外側肌部位
- BDeltoid site三角肌部位
- CVentrogluteal site臀中肌/臀小肌部位（ventrogluteal site）
- DDorsogluteal site臀大肌部位（dorsogluteal site）
— Explanation · 中文詳解 —
對於嬰幼兒（未滿 1 歲），股外側肌（Vastus lateralis）是 IM 注射的首選部位，因其肌肉發展最完整且無重要神經血管經過。背臀部（Dorsogluteal）因坐骨神經風險高，早已被現代護理規範禁用。三角肌（Deltoid）肌肉量不足，不適合嬰兒。
The vastus lateralis is the preferred site for intramuscular injections in infants under six months because it has well-developed muscle mass and lacks major nerves and blood vessels. The deltoid is too small, the ventrogluteal site is reserved for older children and adults, and the dorsogluteal site is contraindicated due to the high risk of sciatic nerve injury.
✦ 台美臨床差異
兩地兒科醫學會對於 IM 注射部位的指引一致，Vastus lateralis 為黃金標準。
