针对病原体采用最有效的抗生素是治疗感染性心内膜炎的关键。已明确病原体者的治愈率较未明确者高得多。因此,在投药前应抽取足够的血培养,甚至推迟投药时间1～2天。抗生素应选用药敏度较高的杀菌剂联用或杀菌剂与抑菌剂联用,维持足够高的浓度与足够长的疗程,以彻底杀灭赘生物中的病原体,减少复发率。 The most effective antibiotic against pathogens is the key to treating infective endocarditis. It has been clear that the cure rate of pathogens is much higher than that of the unidentified ones. Therefore, adequate blood culture should be drawn before administration, and even postponed the administration for 1 to 2 days. Antibiotics should use the higher sensitivity of the fungicide combination or fungicide and bacteriostatic agents, to maintain a high enough concentration and long enough course of treatment to completely kill the pathogens in the neoplasm and reduce the recurrence rate.
