Despite advances in medicine, infection at the surgical site is an impregnation problem that most surgeons confront. Although studies on the seasonality of infection have been conducted in various areas, no study has confirmed the relationship between seasonal temperature and infection after breast reconstruction.
From 2008 to 2018, a retrospective study was conducted on patients who underwent implant-based breast reconstruction. Patient demographics, intraoperative data, postoperative data, and temperature information were collected. Temperature differences between cases with and without infection were examined. The differences in the incidence and risk of infection by season were estimated according to the hot season (July to August) and the nonhot season (September to June).
Of the 460 cases enrolled, 42 cases developed an infection. Among them, 15 (35.71%) cases developed infection during the hot season (P = 0.003). According to the logistic regression model, the risk of infection was 2.639 times higher in the hot season than in the nonhot season (95% confidence interval, 1.282-5.434; P = 0.008). When the temperature was higher than 25°C, the risk of infection increased by 45.2% for every 1°C increase, which was statistically significant (odds ratio, 1.452; 95% confidence interval, 1.198-1.76; P < 0.001).
In conclusion, the hot season or average temperatures higher than 25°C increase the risk of infection in patients undergoing implant-based breast reconstruction. It is essential to focus on skin hygiene during the healing of the incision site.
尽管医学取得了进步，但手术部位感染仍是大多数外科医生面临的棘手问题。尽管已经在不同地区开展了关于感染季节性的研究，但尚无研究证实乳房重建术后季节温度与感染之间的关系。
对 2008 年至 2018 年间接受基于植入物的乳房重建术的患者进行回顾性研究。收集患者的人口统计学、术中数据、术后数据和温度信息。比较感染组和非感染组之间的温度差异。根据热季（7 月至 8 月）和非热季（9 月至 6 月），估计感染发生率和感染风险的季节差异。
在纳入的 460 例病例中，有 42 例发生感染。其中，15 例（35.71%）在热季发生感染（P=0.003）。根据逻辑回归模型，热季感染的风险是非热季的 2.639 倍（95%置信区间，1.282-5.434；P=0.008）。当温度高于 25°C 时，感染风险每增加 1°C 增加 45.2%，具有统计学意义（比值比，1.452；95%置信区间，1.198-1.76；P<0.001）。
总之，热季或平均温度高于 25°C 会增加接受基于植入物的乳房重建术患者的感染风险。在切口愈合期间，需要特别注意皮肤卫生。
