In the United States, there is a large and growing population of patients undergoing dialysis because of end-stage renal disease (ESRD). These patients present special management considerations for dentists, including antibiotic prophylaxis for the prevention of bacterial endocarditis (BE). ESRD patients, particularly those with an arteriovenous shunt for hemodialysis access, are predisposed to valvular endocarditis. Thus, BE prevention is the primary goal of antibiotic prophylaxis prior to dental or other invasive procedures in these patients. Bacteremia may predispose to infection of synthetic vascular access grafts, although this form of endovascular infection in ESRD patients has not been as well-characterized as BE. Antibiotic prophylaxis may be of some benefit for prevention of synthetic graft infections as well as BE. Poor dentist and physician compliance with BE prophylaxis regimens, as well as errors in dosing, timing, or duration of prophylaxis, have been reported. These problems are of particular concern in the treatment of chronically ill patients. In this article, we review the rationale for prophylactic antibiotic therapy prior to dental procedures in ESRD patients with vascular access. We also elaborate on the current American Heart Association guidelines for BE prophylaxis, and address special considerations for ESRD patients.
在美国,因终末期肾病(ESRD)而接受透析的患者数量众多且不断增加。这些患者给牙医带来了特殊的管理考量,包括预防细菌性心内膜炎(BE)的抗生素预防措施。ESRD患者,尤其是那些有用于血液透析通路的动静脉分流的患者,易患瓣膜性心内膜炎。因此,预防BE是这些患者在进行牙科或其他侵入性操作前抗生素预防的主要目标。菌血症可能易导致合成血管通路移植物感染,尽管ESRD患者的这种血管内感染形式尚未像BE那样得到充分描述。抗生素预防对于预防合成移植物感染以及BE可能有一定益处。据报道,牙医和医生对BE预防方案的依从性差,以及预防用药的剂量、时间或持续时间存在错误。这些问题在慢性病患者的治疗中尤为令人担忧。在本文中,我们回顾了有血管通路的ESRD患者在进行牙科手术前预防性抗生素治疗的基本原理。我们还详细阐述了美国心脏协会目前关于BE预防的指南,并讨论了ESRD患者的特殊注意事项。
