Abstract

Purpose: Assessing microbiological culture results is essential in the diagnosis of empyema and appropriate antibiotic selection; however, the guidelines for the management of empyema do not mention assessing microbiological culture intraoperatively. Therefore, we tested the hypothesis that intraoperative microbiological culture may improve the management of empyema.

Methods: We performed a retrospective analysis of 47 patients who underwent surgery for stage II/III empyema from January 2011 to May 2019. We compared the positivity of microbiological culture assessed preoperatively at empyema diagnosis versus intraoperatively. We further investigated the clinical characteristics and postoperative outcomes of patients whose intraoperative microbiological culture results were positive.

Results: The positive rates of preoperative and intraoperative microbiological cultures were 27.7% (13/47) and 36.2% (17/47), respectively. Among 34 patients who were culture-negative preoperatively, eight patients (23.5%) were culture-positive intraoperatively. Intraoperative positive culture was significantly associated with a shorter duration of preoperative antibiotic treatment (p = 0.002). There was no significant difference between intraoperative culture-positive and -negative results regarding postoperative complications.

Conclusions: Intraoperative microbiological culture may help detect bacteria in patients whose microbiological culture results were negative at empyema diagnosis. Assessing microbiological culture should be recommended intraoperatively as well as preoperatively, for the appropriate management of empyema.

脓胸患者术中微生物培养的评估:与术前微生物培养的比较。
目的:评估微生物培养结果对脓胸的诊断和合理选择抗生素至关重要;然而,脓胸处理指南没有提到术中微生物培养的评估。因此,我们验证了术中微生物培养可能改善脓胸管理的假设。方法:我们对2011年1月至2019年5月期间接受II/III期脓胸手术的47例患者进行回顾性分析。我们比较了术前与术中在诊断脓胸时评估的微生物培养阳性。我们进一步研究术中微生物培养结果阳性患者的临床特点和术后结果。结果:术前和术中微生物培养阳性率分别为27.7%(13/47)和36.2%(17/47)。34例术前培养阴性患者中,术中培养阳性8例(23.5%)。术中阳性培养与术前较短的抗生素治疗时间显著相关(p = 0.002)。术中培养阳性和阴性结果在术后并发症方面无显著差异。结论:术中微生物培养有助于对微生物培养阴性的患者进行细菌检测。评估微生物培养应推荐术中以及术前,为适当的管理脓胸。
