背景：新生儿口罩的定位和持有技术各不相同。研究表明，无论操作人员的经验如何，面罩上的泄漏是常见的，而且往往是严重的。目的：(1)确定一种口罩放置和保持技术，以尽量减少口罩泄漏。(2)探讨对两种圆口罩进行书面指导和鉴定技术的演示对口罩泄漏的影响。方法：三名经验丰富的新生儿医师比较Fisher & Paykel 60 mm和Laerdal 0/1尺寸口罩放置和保持口罩的方法，以尽量减少泄漏。50名临床工作人员对一个改良的人体模型进行正压通气，该模型旨在测量面罩的泄漏。他们被提供了关于如何放置和握住每个面具的书面说明，然后接受了演示。每次教学干预后测量口罩泄漏量。结果：确定了一种定位和持口罩的技术，最大限度地减少了泄漏。Laerdal面罩在教学前、教学后和演示后的平均（SD）泄漏率分别为55%（31）、49%（30）、33% (26)，Fisher & Paykel面罩为57%（25）、47%（28）、32%（30）。两种口罩的泄漏量无显著差异。单独的书面说明减少了8.8%的泄漏（CI 1.4%至16.2%）；当与演示面罩结合使用时，泄漏率降低了24.1% （CI为16.4%至31.8%）。结论：书面指导和示范确定的最佳技术可显著减少口罩泄漏。
Background: Techniques of positioning and holding neonatal face masks vary. Studies have shown that leak at the face mask is common and often substantial irrespective of operator experience. Aims: (1) To identify a technique for face mask placement and hold which will minimise mask leak. (2) To investigate the effect of written instruction and demonstration of the identified technique on mask leak for two round face masks. Method: Three experienced neonatologists compared methods of placing and holding face masks to minimise the leak for Fisher & Paykel 60 mm and Laerdal size 0/1 masks. 50 clinical staff gave positive pressure ventilation to a modified manikin designed to measure leak at the face mask. They were provided with written instructions on how to position and hold each mask and then received a demonstration. Face mask leak was measured after each teaching intervention. Results: A technique of positioning and holding the face masks was identified which minimised leak. The mean (SD) mask leaks before instruction, after instruction and after demonstration were 55% (31), 49% (30), 33% (26) for the Laerdal mask and 57% (25), 47% (28), 32% (30) for the Fisher & Paykel mask. There was no significant difference in mask leak between the two masks. Written instruction alone reduced leak by 8.8% (CI 1.4% to 16.2%) for either mask; when combined with a demonstration mask leak was reduced by 24.1% (CI 16.4% to 31.8%). Conclusion: Written instruction and demonstration of the identified optimal technique resulted in significantly reduced face mask leak.
