In both human and veterinary medicine, it is recommended that an anesthetic machine checkout procedure (preuse check) be performed daily, with some items tested before each case, to confirm safe function and the check results recorded.
The objective of this prospective study was to evaluate anesthetic machines in private veterinary clinics in Alberta (Canada) using a standardized checkout procedure.
One-hundred consecutive anesthetic machines were assessed. For each item of the checkout procedure, a "pass," "fail," or "not applicable" score was awarded. "Not applicable" indicated an item that could not be evaluated.
Few machines (10%) evaluated had a secondary oxygen supply, no machines had an oxygen supply pressure alarm, and leaks were identified in 31 and 17% of rebreathing and non-rebreathing systems, respectively. Thirty-nine percent of machines did not have a high-pressure circuit alarm, 86% of machines were attached to an active scavenging system, although it was improperly connected in 56% of cases, and only 2% of machines were accompanied by a checkout log.
There was widespread variation in anesthetic machine standards and function, highlighting the value of performing a regular machine checkout procedure in creating a foundation for safe anesthetic practice.
在人类医学和兽医医学中，都建议每天进行麻醉机检查程序（使用前检查），有些项目在每次使用前进行测试，以确认安全功能并记录检查结果。
本前瞻性研究的目的是使用标准化的检查程序评估艾伯塔省（加拿大）私人兽医诊所的麻醉机。
评估了 100 台连续麻醉机。对于检查程序的每个项目，给予“通过”、“失败”或“不适用”评分。“不适用”表示无法评估的项目。
很少有机器（10%）有备用氧气供应，没有机器有氧气供应压力警报，并且在重新呼吸和非重新呼吸系统中分别发现了 31%和 17%的泄漏。39%的机器没有高压回路警报，86%的机器连接到主动清除系统，但在 56%的情况下连接不当，只有 2%的机器附有检查记录。
麻醉机的标准和功能存在广泛差异，这突出了定期进行机器检查程序的价值，为安全麻醉实践奠定了基础。
