The studies on cardiovascular alterations when using an N95 respirator or surgical mask-covered N95 during dental treatments are limited.
To investigate and compare the cardiovascular responses of dentists treating paediatric patients while wearing an N95 respirator or a surgical mask-covered N95.
This was a crossover clinical trial in 18 healthy dentists wearing an N95 respirator or surgical mask-covered N95 during the dental treatment of paediatric patients. Oxygen saturation (SpO ), heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), and mean arterial pressure (MAP) were monitored at baseline, intraoperation, and postoperation. The data were analyzed using the generalized estimating equation.
The mean SpO , HR, SBP, DBP, and MAP significantly changed from baseline up to the end of the procedures after wearing an N95 by 3.1%, 19.3%, 11.5%, 17.7%, and 13.8% and after wearing a surgical mask-covered N95 by 3.0%, 20.2%, 5.3%, 13.9%, and 8.8%, respectively (p < .05). No significant differences in these values were found between groups (p > .05).
N95 respirators and surgical mask-covered N95s significantly impact the cardiovascular responses of dentists treating paediatric patients with no differences between the two types of masks.
使用 N95 口罩或覆盖 N95 的手术口罩进行牙科治疗时心血管变化的研究有限。
研究并比较戴 N95 口罩或覆盖 N95 的手术口罩的牙医在治疗儿科患者时的心血管反应。
这是一项交叉临床试验，18 名健康牙医在治疗儿科患者时佩戴 N95 口罩或覆盖 N95 的手术口罩。在基线、手术中和手术后监测血氧饱和度（SpO ）、心率（HR）、收缩压（SBP）、舒张压（DBP）和平均动脉压（MAP）。使用广义估计方程分析数据。
佩戴 N95 后，SpO 、HR、SBP、DBP 和 MAP 从基线到手术结束分别平均变化 3.1%、19.3%、11.5%、17.7%和 13.8%，佩戴覆盖 N95 的手术口罩后分别变化 3.0%、20.2%、5.3%、13.9%和 8.8%（p<0.05）。两组间这些值无显著差异（p>0.05）。
N95 口罩和覆盖 N95 的手术口罩显著影响治疗儿科患者的牙医的心血管反应，两种口罩之间没有差异。
