抗生素一般使用原則 抗生素 相關過敏反 應 常見的感染症致病菌 抗生素的分類 抗生素使用常見錯誤 抗素使用的適應症 常見感染症的抗生素療程

抗生素一般使用原則

Narrow spectrum 一種細菌用一種藥物治療 足量藥物治療 完整療程

使用抗生素之前應

用手取得檢體染色培養 用眼觀察染色特徵 用腦社區型感染或院內感染 想想看最可能的致病菌是什麼 藥物敏感性如何

理想的抗生素 Maximal damage to the bacteria minimal damage to the host ndashselective toxicity Single use High effectiveness Low cost No side-effect

Principles of antibiotic therapy Host factors Allergy history Age Body weight Renalliver function Immune status Site of infection pathogen route of

Empirical therapy must be adjusted after culture become available

Definite antimicrobial therapy ndashchange broad- spectrum coverage to specific pathogen
