The severe acute respiratory syndrome corona virus 2(SARS-Cov2) virus replicates in the nasal cavity, nasopharynx, and the oropharynx. During oral surgery, the risk of viral transmission is high during instrumentation in these areas, while performing airway management procedures, the oral surgery itself, and related procedures. During the corona virus disease 2019 (COVID-19) pandemic, patients with an oral pathology usually present for emergency procedures. However, patients with oral cancer, being a semi-emergency, may also present for diagnostic and therapeutic procedures. When elective surgeries are resumed, these patients will come to the operating room. In asymptomatic patients, the false-negative rate can be as high as 30%. These patients are a source of infection to the healthcare workers and other patients. This mandates universal precautions to be taken for all patients presenting for surgery. Lesions along the airway, distorted anatomy secondary to cancer therapy, shared airway with the surgeon, surgical handling of the airway and the risk of bleeding, make airway management challenging in these patients, especially while wearing personal protective equipment. Airway management procedures, oral surgery, use of cautery, and other powered surgical instruments in the aero digestive tract, along with constant suctioning are a source of significant aerosol generation, further adding to the risk of viral transmission. Maintaining patient safety, while protecting the healthcare workers from getting infected during oral surgery is paramount. Meticulous advance planning and team preparation are essential. In this review, we discuss the challenges and recommendations for safe anesthesia practice for oral surgery during the COVID-19 pandemic, with special emphasis on risk mitigation.
严重急性呼吸综合征冠状病毒2(SARS-CoV-2)在鼻腔、鼻咽和口咽中复制。在口腔手术期间,在这些区域进行器械操作、实施气道管理程序、进行口腔手术本身及相关程序时,病毒传播风险很高。在2019冠状病毒病(COVID-19)大流行期间,患有口腔疾病的患者通常会进行急诊手术。然而,患有口腔癌的患者,虽为半急诊情况,但也可能会进行诊断和治疗程序。当择期手术恢复时,这些患者将进入手术室。在无症状患者中,假阴性率可能高达30%。这些患者是医护人员和其他患者的感染源。这就要求对所有前来手术的患者采取普遍预防措施。气道沿线的病变、癌症治疗导致的解剖结构变形、与外科医生共用气道、气道的外科处理及出血风险,使得这些患者的气道管理具有挑战性,尤其是在穿戴个人防护装备时。气道管理程序、口腔手术、在空气消化道中使用烧灼术及其他动力外科器械,以及持续吸引,都是大量气溶胶产生的来源,进一步增加了病毒传播风险。在保护医护人员在口腔手术期间不被感染的同时确保患者安全至关重要。精心的预先规划和团队准备必不可少。在本综述中,我们讨论了COVID-19大流行期间口腔手术安全麻醉实践的挑战和建议,特别强调风险缓解。
