BACKGROUND
Nitrous oxide (NO) has seen a marked decline in its usage in recent years due to its adverse clinical effects. We audited the practice in our department to evaluate the NO consumption and cost-effectiveness of its supply.
METHODOLOGY
Electronic anesthesia records of all patients anesthetized in our main operating rooms in a typical month were reviewed retrospectively, and utilization of NO was noted in addition to the patient demographics, surgical procedure, and specialty.
RESULTS
A total of 950 patients were anesthetized, and 3.1% received NO. The annual usage was estimated to be 72,871 liters, with a leakage of 3,883,105 liters to the environment, posing a safety hazard and wasting 149,612.50 SAR.
CONCLUSION
Notable costs and environmental benefits may be achieved by substituting a piped supply of NO with portable E-cylinders on demand in operating rooms for rational use.
背景
由于一氧化二氮（NO）的不良临床效应，其近年来的使用量显著下降。我们对本部门的情况进行了审核，以评估一氧化二氮的消耗量及其供应的成本效益。
方法
回顾性审查了典型月份在我们主要手术室接受麻醉的所有患者的电子麻醉记录，除了患者人口统计学、手术程序和专业外，还记录了一氧化二氮的使用情况。
结果
共有950例患者接受麻醉，3.1%的患者使用了一氧化二氮。估计年使用量为72,871升，有3,883,105升泄漏到环境中，造成安全隐患并浪费了149,612.50沙特里亚尔。
结论
通过在手术室中按需用便携式电子气瓶替代管道供应的一氧化二氮以实现合理使用，可显著节省成本并带来环境效益。
