Abstract

The use of a simple oxygen facemask (Hudson) with high oxygen inflow (48 l.min-1) was investigated as a technique for pre-oxygenation, comparing it with the Magill system (oxygen flow: 100 ml.kg-1.min-1). One hundred and thirty-eight patients scheduled for elective gynaecological and orthopaedic surgery were studied: group 1, Hudson mask and group 2, Magill system (ASA 1-2, n = 107); group 3, Hudson mask and group 4, Magill system (ASA 3, n = 30). Pre-oxygenation was assessed by measuring the times to 97%, 95% and 93% arterial desaturation (finger pulse oximetry) following 3 min of pre-oxygenation. The times taken to achieve these end-points in all the study groups suggest that the Hudson mask offers an alternative technique for pre-oxygenation.

摘要

研究了使用高氧流量（48升·分钟⁻¹）的简易氧气面罩（哈德森面罩）作为预充氧技术，并将其与马吉尔系统（氧流量：100毫升·千克⁻¹·分钟⁻¹）进行比较。对138例计划进行择期妇科和骨科手术的患者进行了研究：第1组，哈德森面罩；第2组，马吉尔系统（美国麻醉医师协会分级1 - 2级，n = 107）；第3组，哈德森面罩；第4组，马吉尔系统（美国麻醉医师协会分级3级，n = 30）。通过测量预充氧3分钟后动脉血氧饱和度降至97%、95%和93%（手指脉搏血氧饱和度测定）所需的时间来评估预充氧情况。所有研究组达到这些终点所需的时间表明，哈德森面罩提供了一种替代的预充氧技术。
