慶大霉素（Gentamicin）屬於氨基糖苷類抗生素（Aminoglycoside Antibiotics），廣泛用於治療嚴重的革蘭氏陰性菌感染。儘管其抗菌效果顯著，但這類藥物具有潛在的腎毒性（Nephrotoxicity）和耳毒性（Ototoxicity）等嚴重副作用。耳毒性會影響內耳的聽覺和平衡功能，可能導致永久性損傷。護理師在監測使用慶大霉素的病人時，必須密切觀察並辨識耳毒性的早期徵兆，以便及早介入，調整治療方案，從而保護病人的聽覺和平衡功能。這項監測對於確保病人安全和生活品質至關重要。
Gentamicin belongs to the aminoglycoside class of antibiotics and is widely used to treat serious gram-negative infections. Despite its potent antimicrobial activity, this class of medication has significant nephrotoxic and ototoxic potential. Ototoxicity affects inner ear hearing and balance and can cause permanent damage. When monitoring a client receiving gentamicin, the nurse must observe closely for early signs of ototoxicity, so that the regimen can be adjusted promptly to protect hearing and balance. Such monitoring is essential for patient safety and quality of life.
慶大霉素（Gentamicin）的臨床應用與其潛在的耳毒性、腎毒性監測在台灣和美國的臨床實踐中是高度一致的。兩地醫護人員都會強調監測血中藥物濃度（如尖峰濃度和谷底濃度）、評估聽力及前庭功能變化（如耳鳴、頭暈、聽力下降、共濟失調）的重要性。用藥劑量調整也都會考量腎功能。因此，此題的臨床實踐在兩地並無顯著差異。
