Abstract

Objectives

To assess the extent of staff exposure to aerosol generation in common pediatric otorhinolaryngological procedures (tonsillotomies, adenoidectomies, and tympanostomies) and determine the surgical phases responsible for most aerosol generation in these procedures.

Methods

Aerosol generation was measured during 35 pediatric otolaryngological procedures using an Optical Particle Sizer that measures aerosol concentrations for particle sizes between 0.3 and 10.0 μm. The different phases of and instruments used in each procedure were logged. Operating room background aerosol levels and coughing were used as references.

Results

Total aerosol concentrations were significantly higher during tonsillotomies and adenoidectomies when compared to tympanostomies (p = 0.011 and p = 0.042) and to empty room background aerosol concentrations (p = 0.0057 and p < 0.001). Aerosol concentration during tonsillotomies did not differ from coughing, which is considered as standard for high-risk aerosol procedures. During tympanostomies, aerosol concentrations were even lower than during perioperative concentrations. No statistically significant difference in aerosol generation comparing suction, electrocautery, cold instruments, and paracentesis was found.

Conclusion

According to the results of this study, tympanostomies are low-risk aerosol-generating procedures. On the other hand, pediatric tonsillotomies produced aerosols comparable to coughing, pointing to them being significantly aerosol-producing procedures and viral transmission is theoretically possible intraoperatively.

小儿耳鼻喉科手术过程中产生的气溶胶。

目的评估小儿耳鼻喉科常见手术（扁桃体切除术、腺样体切除术和鼓室造口术）中工作人员接触气溶胶产生的程度，并确定这些手术中产生气溶胶最多的手术阶段：使用光学粒子测定仪测量了 35 个小儿耳鼻喉科手术过程中产生的气溶胶，该仪器可测量 0.3 至 10.0 μm 粒径的气溶胶浓度。记录了每个手术的不同阶段和使用的仪器。以手术室背景气溶胶水平和咳嗽声为参考：结果：扁桃体切除术和腺样体切除术的气溶胶总浓度明显高于鼓室造口术（p = 0.011 和 p = 0.042）和空房间背景气溶胶浓度（p = 0.0057 和 p 结论：扁桃体切除术和腺样体切除术的气溶胶总浓度明显高于鼓室造口术和空房间背景气溶胶浓度（p = 0.011 和 p = 0.042）：根据这项研究的结果，鼓膜造口术是低风险的气溶胶产生程序。另一方面，小儿扁桃体切开术产生的气溶胶与咳嗽的气溶胶相当，这表明扁桃体切开术是产生大量气溶胶的手术，理论上术中有可能发生病毒传播。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
