前言:

    在自体取髂骨移植或骨折内固定时,遭遇较大骨块掉落至地面,如何优雅地捡起来?循证医学给出了答案。

在骨科手术中,经常需要进行自体骨移植,其中又以取髂骨最为常见。在手术中偶尔会出现移植骨块掉落,在这种情况下,掉落骨块能否重新消毒再用,成为困扰医生的难题

针对上述问题,国外学者进行了一项循证医学研究,对骨块是否能再用及最佳的消毒方式作出了解答。上述内容发表在2021.02期JOT杂志上。

Objective

进行一项系统研究,以评估掉落至手术室地面的移植物骨块的污染率,微生物特征(污染生物)和术中消毒方法的有效性和细胞毒性。 

(To perform a systematic review of the literature to determine the rate of contamination of autologous bone fragments inadvertently dropped on the operating room floor, the microbial profile (contaminating organism), and the outcome of intraoperative decontamination techniques in terms of effectiveness and cellular toxicity.)


Date sources

在PubMed、Medline和Embase中搜索1990年至2020年间使用如“骨移植物污染”,“掉落骨块”,“自体骨消毒”和类似的可互换词语的英语文献。

(PubMed, Medline, and Embase were searched for English literature published from 1990 through 2020 using terms such as “bone graft contamination,” “dropped osteoarticular fragments,” “autogenous bone decontamination,” and similar interchangeable words.)

Study selection

研究遵循系统评价和meta分析的首选报告项目。纳入标准包括以下所有研究:宿主骨块的污染、手术室中自体骨污染的均值和/或发生率,受污染的自体骨的微生物分析,消毒的结局以及消毒后的细胞活力。

(Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed. Inclusion criteria consisted of all studies on contamination of host bone fragments, means and/or rate of autologous bone contamination in operating rooms, microbial analysis of contaminated bone autograft, outcome of decontamination, and cellular viability after decontamination.)

Conclusion

骨关节或骨软骨宿主骨块掉落后的污染率接近40%。表皮金黄色葡萄球菌是掉落在手术室地面骨块的最常见污染物。事实证明,在10%聚维酮碘溶液中浸泡5分钟,然后用生理盐水冲洗1分钟,可以成功地消毒和维持细胞活力。

(The rate of contamination for dropped osteoarticular or osteochondral host fragment approached 40%. Staphylococcus epidermidis was the most common organism contaminating the bone graft when dropped on the operating room floor. A 5-minute bath in 10% povidone-iodine solution followed by 1-minute bulb syringe lavage with normal saline has proved successful in decontamination and maintenance of cellular viability.)
