目的:外科羽流已知存在潜在的职业健康危害。这项研究比较了不同小儿扁桃体切除术手术技术之间产生的手术羽流中的纳米颗粒浓度,并评估了缓解措施的有效性。
方法:这是一项在三级护理学术中心进行的横断面研究。使用四种技术对60例患者进行了囊外或囊内扁桃体切除术,另外10例患者使用了缓解措施。两个纳米颗粒计数器用于测量颗粒浓度:CPC™和DiSCmini™。扁桃体切除术技术包括:(1)微清器(MD),(2)由助手(B)手动抽吸的博维,(3)带有内置排烟系统(BS)的Bovie,和(4)Coblator™(CB)。缓解组(BSY)和(CBY)使用了额外的Yankauer抽吸。使用单向ANOVA对组之间的等级和成对比较进行比较分析。
结果:DiSCmini颗粒计数器的平均浓度(颗粒/cm3)和变体系数为MD:5140(1.6),B:30700(1.5),BS:25001(0.8),CB:54814(1.7),CBY:2395(1.3)和BSY:11552(1.0)。CPC颗粒计数器的平均浓度为MD:1223(1.4),B:3405(0.7),BS:5002(0.9),CB:13273(1.0),CBY:1048(1.2)和BSY:3046(0.6)。在使用MD的情况下,平均浓度最低,在使用CB的情况下,平均浓度最高。然而,缓解后,CBY的总体水平最低。
结论:扁桃体切除术技术确实会影响手术羽流中发射的纳米颗粒水平,这可能会给手术室人员带来职业危害。

OBJECTIVE: Surgical plume has known potential occupational health hazards. This study compares nanoparticle concentrations in surgical plumes generated between different pediatric tonsillectomy surgical techniques and assesses the efficacy of mitigation measures.
METHODS: This is a cross-sectional study performed at a tertiary care academic center. Extracapsular or intracapsular tonsillectomy was performed in 60 patients using four techniques and in 10 additional patients using mitigation measures. Two nanoparticle counters were used to measure
particulate concentrations: CPC™ and DiSCmini™. Tonsillectomy techniques included: (1) microdebrider (MD), (2) Bovie with manual suctioning by an assistant (B), (3) Bovie with built-in smoke evacuation system (BS), and (4) Coblator™ (CB). An additional Yankauer suction was used in the mitigation groups (BSY) and (CBY). Comparative analysis was performed using one-way ANOVA on ranks and pairwise comparisons between the groups.
RESULTS: The mean concentrations (particles/cm3) and coefficient of variants for the DiSCmini
particulate counter were MD: 5140 (1.6), B: 30700 (1.5), BS: 25001 (0.8), CB: 54814 (1.7), CBY: 2395 (1.3) and BSY: 11552 (1.0). Mean concentrations for the CPC
particulate counter were MD: 1223 (1.4), B: 3405 (0.7), BS: 5002 (0.9), CB: 13273 (1.0), CBY: 1048 (1.2) and BSY: 3046 (0.6). The lowest mean concentrations were noted in cases using MD and the highest in cases using CB. However, after mitigation, CBY had the lowest overall levels.
CONCLUSIONS: Tonsillectomy technique does impact the levels of nanoparticles emitted within the surgical plume, which may present an occupational hazard for operating room personnel.
