关节置换术后感染预防的研究进展

Research Progress of Infection Prevention after Joint Replacement

假体关节感染(PJI),也称为假体周围感染,是关节置换术后的最严重并发症之一,早期感染的体征为持续存在的局部疼痛,红斑,水肿,伤口愈合困难,大血肿和发热。持久关节疼痛或疼痛增加和早期松弛是迟发性感染的标志,晚期感染表现为出现全身症状或作为未识别后的亚急性感染菌血症。无论早期还是晚期感染都会为患者带来巨大的伤害,本文章主要对PJI的预防根据术前、术中以及术后分为三个部分进行综述,希望能够为临床医师提供参考,以减少PJI的发生率,从而尽可能为行关节置换术的患者减少痛苦。

Prosthesis joint infection (PJI), also known as periprosthesis infection. It is one of the most serious complications after joint replacement. Signs of early infection are persistent local pain, erythema, edema, difficulty in wound healing, large hematoma, and fever. Prolonged joint pain or increased pain and early relaxation are the hallmarks of delayed infection, and late infection is manifested as systemic symptoms or as subacute infection bacteremia after unrecognized. No matter early or late infection will bring great harm to patients. This article mainly summarizes the prevention of PJI in three parts according to preoperative, intraoperative and postoperative, hoping to serve as a ref-erence for clinicians to reduce the incidence of PJI, so as to reduce the pain of patients undergoing joint replacement as much as possible.
