Abstract

Background

The healthcare sector emits 5% of greenhouse gases worldwide, inhaled anaesthetic agents have contributed to this effect for years. Other countries measured and limited their use, leading to positive environmental changes. There is a lack of data on Colombia. This project aims to evaluate the environmental impact of desflurane, isoflurane, and sevoflurane between 2019 and 2022 in a hospital in Bogota.

Methods

A retrospective exploration of inhaled anaesthetic agents use was conducted using our hospital's pharmacy inventory between 2019 and 2022. ORACLE software tools were used, along with the amount of anaesthetics dispensed by the pharmacy. The CO₂ equivalent was calculated in kilograms using the global warming potential at 20 and 100 years.

Results

A total of 743 kg of inhaled anaesthetic agents was administered between 2019 and 2022. Sevoflurane accounted for 265.7 kg, Desflurane for 473.9 kg, while isoflurane was used in smaller quantities. There was a change in the trend between 2019/2020 and 2021/2022, with an increase of 69.3 kg in sevoflurane use and a decrease of 86.2 kg in desflurane use. The CO₂ emissions from desflurane decreased from 190.7 to 131.9 t over 20 years and from 711 to 492 t over 100 years.

Conclusions

The use of sevoflurane increased by 70%, whereas that of desflurane decreased by 31%. CO₂ emissions were reduced by 557 t in 20 years and 210 t in 100 years. The environmental impact of sevoflurane is 97% lower than desflurane in our OR’s.

2019 - 2022年某高复杂性教学医院挥发性麻醉药环境影响的定量分析

背景：医疗保健部门排放了全球5%的温室气体，吸入麻醉剂多年来一直造成这种影响。其他国家衡量和限制它们的使用，导致积极的环境变化。缺乏关于哥伦比亚的数据。该项目旨在评估2019年至2022年期间波哥大一家医院使用地氟烷、异氟烷和七氟烷对环境的影响。方法：利用我院2019 - 2022年药房库存资料对吸入麻醉剂使用情况进行回顾性调查。使用ORACLE软件工具，以及药房分配的麻醉药量。二氧化碳当量以公斤为单位，使用20年和100年的全球变暖潜能值计算。结果：2019 - 2022年共使用吸入麻醉剂743 kg。七氟烷占265.7千克，地氟烷占473.9千克，异氟烷用量较少。从2019/2020年到2021/2022年，趋势有所变化，七氟醚使用量增加了69.3千克，地氟醚使用量减少了86.2千克。地氟醚的二氧化碳排放量在20年内从190.7吨减少到131.9吨，在100年内从711吨减少到492吨。结论：七氟醚用量增加70%，地氟醚用量减少31%。二氧化碳排放量20年减少557吨，100年减少210吨。在我们的手术室中，七氟醚对环境的影响比地氟醚低97%。
