用于乳房植入物的局部抗生素 (BREAST-AB)
使用庆大霉素、万古霉素和头孢唑林抗生素溶液对接受乳房重建手术的女性进行乳房植入物的预防性治疗：一项随机对照试验（BREAST-AB 试验）
The BREAST-AB Trial is a multi-center, randomized, double blind, placebo-controlled trial investigating the efficacy of local application of gentamicin, vancomycin and cefazolin in decreasing all-cause implant explantation after breast reconstruction.

详细说明
The BREAST-AB Trial will include women undergoing breast reconstruction with implants. The objective is to determine the efficacy of local antibiotics in decreasing all-cause implant explantation. Participants will be randomized to local application of placebo or gentamicin, vancomycin and cefazolin in a saline solution onto the implant and the dissected breast pocket. All patients undergoing unilateral breast reconstruction will be randomized to the trial drug or placebo in a ratio of 1:1. All patients undergoing bilateral reconstruction will be randomized to the trial treatment on one of their breasts and placebo to the contralateral breast. A total number of 1274 of breasts undergoing breast reconstruction will be included in the trial.

All-cause explantation of the breast implant after the breast reconstruction surgery
大体时间：180 days
|
All-cause explantation will be defined as explantation and discarding of the implant. Replacement of an expander with a permanent implant and replacement of a permanent breast implant with a new permanent breast implant due to cosmetic revisions such as asymmetry, implant malposition, change of size or implant rotation will not be counted as an explantation. |

IPD 计划说明
The protocol including the statistical analysis plan is published in BMJ Open (doi:10.1136/bmjopen-2021-058697) prior to unblinding. The main article will include the primary and secondary outcomes. The tertiary and long-term outcomes will be included in subsequent articles. The manuscripts will be submitted to peer-reviewed international journals and both positive, negative and inconclusive results will be published. The findings of the trial will be shared with participating sites and presented at national and international conferences. The results will be disseminated to the public but will not be shared directly with participating patients.
IPD 共享时间框架
After the end of the trial, the data will become available (Anticipated july 2025)
IPD 共享访问标准
Researchers and other relevant parties can be granted access to selected anonymized data after publication upon request to the principal-sponsor investigator
