Abstract：
This study aims to investigate the association of time to oral and maxillofacial surgery after Covid-19 infection with the risk of postoperative complications in a population from China. In the current study, a total of 1342 consecutive patients underwent general anesthesia (GA) in the maxillofacial district of the Chinese Oral and Maxillofacial COVID Collaborative, which consists of 27 teaching hospitals. Pulmonary, cardiovascular and thrombotic complications were monitored for 1 month after GA surgery (GAS) and their incidence was reported for the first 30 days. Post-operative complications were observed in 4 of 1076 cases (0.37%) who had suffered from mild Omicron infection and in none of the controls. Results from the Quasi-Poisson multivariate regression models showed that Omicron infection was not associated with increased post-operative complications compared to controls. Among the infected patients, delays of >4 but not >6 weeks were associated with lower OR of complications (0.08, 95% CI 0.01-0.78 and 0.06, 95% CI 0.01-1.80, respectively). Findings of this study suggest that delaying surgery for a period of 4-6 weeks following infection can provide a protective effect.
摘要：
本研究旨在调查中国人群新冠肺炎感染后口腔颌面手术时间与术后并发症风险的关系。在目前的研究中,共有1342名连续患者在中国口腔颌面部COVID协作组的颌面部接受了全身麻醉（GA），由27家教学医院组成。肺,肺在GA手术(GAS)后1个月监测心血管和血栓性并发症,并报告前30天的发生率.1076例中有4例（0.37％）患有轻度Omicron感染，无对照组。准泊松多元回归模型的结果表明，与对照组相比，Omicron感染与术后并发症增加无关。在受感染的患者中，>4但不>6周的延迟与并发症的OR降低相关(分别为0.08,95%CI0.01-0.78和0.06,95%CI0.01-1.80).这项研究的结果表明，在感染后将手术推迟4-6周可以提供保护作用。
