治疗危重深部真菌感染的唯一有效药是()。

A.青霉素

B.氯霉素

C.两性霉素B

D.克林霉素

E.克霉唑

答案

参考答案:C

解析:本组题考查要点是“两性霉素B、克霉唑、青霉素及氯霉素的临床应用”。两性霉素B毒性大,不良反应多见,但又是治疗危重深部真菌感染的唯一有效药,选用时必须权衡利弊后作出决定。克霉唑仅局部用于治疗浅部真菌病和皮肤黏膜念珠菌感染。青霉素为以下感染的首选药:①溶血性链球菌感染,如咽炎、扁桃体炎、猩红热、丹毒、蜂窝织炎和产褥热等;.②肺炎链球菌感染如肺炎、中耳炎、脑膜炎和菌血症等;③不产青霉素酶葡萄球菌感染;④炭疽;⑤破伤风、气性坏疽等梭状芽孢杆菌感染;⑥梅毒(包括先天性梅毒);⑦钩端螺旋体病;⑧回归热;⑨白喉;⑩青霉素与氨基糖苷类药物联合用于治疗草绿色链球菌心内膜炎。氯霉素首选用于治疗伤寒、副伤寒。其次可以治疗严重沙门菌属感染合并败血症。治疗耐氨苄西林的B型流感嗜血杆菌脑膜炎或对青霉素过敏患者的肺炎链球菌、脑膜炎奈瑟菌脑膜炎、敏感的革兰阴性杆菌脑膜炎。
