Explanation · 中文詳解

為嬰兒進行肌肉注射時,選擇正確的注射部位是預防神經或血管損傷的關鍵,尤其嬰兒的肌肉量相對較小且神經血管分佈密集。護理師必須根據嬰兒的年齡和肌肉發育狀況,選擇最安全、最合適的部位。 股外側肌 (Vastus lateralis muscle) 之所以是嬰兒肌肉注射的首選,是因為它是嬰兒時期發育最完善且肌肉量足夠的肌肉,同時其周圍沒有重要的神經或大血管經過,大大降低了神經損傷(如坐骨神經)或血管穿刺的風險,確保了注射的安全性與藥物吸收的有效性。這符合「降低風險潛能 (Reduction of Risk Potential)」的護理原則,優先考量病人的安全。 其他選項的部位,在嬰兒身上則有較高的風險,不應作為首選。

The vastus lateralis is the preferred site for intramuscular injections in infants because it is well-developed and free of major nerves and blood vessels, minimizing injury risk. Other sites like the dorsogluteal or deltoid are avoided due to higher risks of nerve damage or insufficient muscle mass.
