Summary
This study aimed to quantify the blood content of aerosols produced during dental, maxillofacial and autopsy procedures and to identify those activities which involve the greatest risk of infection due to exposure to blood-containing aerosols. A total of 132 air samples were taken in several dental cubicles, a maxillofacial operating theatre and an autopsy room. The concentration of haemoglobin (Hb) in the samples was quantified and, for each day of sampling, the concentration of blood/m3 of air aspirated (μL blood/m3 air) was calculated. Hb was detected in 38.64% of samples. The mean concentration of Hb in the samples was 0.10 ± 0.19 μg Hb/m3 of aspirated air, with a range of 0–0.72 μg Hb/m3. No statistically significant differences in the concentration of blood aerosol per m3 of aspirated air were noted among the three types of activity analysed (P > 0.05). Although there is, as yet, no concrete proof of the risk of infection through blood-containing aerosols, minimising the production and dispersal of aerosols and spatters is strongly recommended.

size=3]对132份空气样本中的血红蛋白浓度进行检测,样本分别来自几个牙科诊所、一个上颌骨手术室和一个尸体解剖室。38.64%样本检测出血红蛋白,每立方米空气中血红蛋白浓度为0.10 ± 0.19 μg ,浓度范围0–0.72 μg /m3。三种场所的空气中含血气溶胶浓度无统计学显著差异 (P > 0.05)。尽管至今仍然没有充分证据显示含血气溶胶有感染的风险,但尽量减少气溶胶和喷溅物的产生还是强烈建议的。

慢看了。谢谢!我们也正在做一个实验,现在的数据显示:空气和感染好像没什么关系。
