概括

在急性尾炎中,手术前的抗生素没有减少尾孔隙. 然而,在这个随机试验中,它们略有降低了手术部位感染.

科学领域:

外科手术医疗外科手术
传染性疾病传染性疾病
临床试验临床试验

背景情况:

急性无并发性尾炎很常见,治疗指南各不相同.
抗生素通常用于手术前,但它们在减少穿孔的益处的证据有限.

研究的目的:

确定手术前的抗生素治疗是否能降低急性无并发性尾炎的成年人尾孔穿孔率.

主要方法:

一个多中心的,开放的,非劣势的随机临床试验,涉及成年人,疑似无并发性急性尾炎.
在尾切除手术前,患者接受了手术前的黄素和甲尼达或没有抗生素.
主要结局是在手术期间诊断出的尾穿孔.

主要成果:

术前抗生素 (8.3%) 与没有抗生素 (8.9%) 相比,没有显著降低穿孔率,符合非劣质标准 (绝对差异为0.6%).
抗生素组 (1.6%) 的手术部位感染率低于没有抗生素组 (3.2%).

结论:

当手术在24小时内进行时,手术前的抗生素给药不会降低急性尾炎中尾孔的风险.
抗生素可能在减少手术部位感染方面提供轻微的好处.
