The environmental impacts of anesthesia

Area of Science:

• Environmental Science
• Anesthesiology
• Healthcare Sustainability

Background:

• The healthcare sector, particularly anesthesia, has a considerable environmental footprint.
• Anesthetic gases are potent greenhouse gases, and waste from medications and single-use devices contributes to environmental pollution.
• Operating rooms generate substantial amounts of solid waste, increasing the environmental burden.

Purpose of the Study:

• To review the environmental impacts associated with anesthetic practices.
• To identify and suggest mitigation strategies for reducing the environmental footprint of anesthesia delivery.
• To highlight the urgency of implementing sustainable practices in the context of the climate crisis.

Main Methods:

• Review of current anesthetic practices and their environmental consequences.
• Analysis of the carbon footprint of various anesthetic agents.
• Evaluation of waste management strategies for medications and single-use devices.

Main Results:

• Nitrous oxide and desflurane have the highest carbon footprint among anesthetic agents.
• Low fresh gas flows and the use of propofol can significantly reduce emissions.
• Minimizing medication waste, ensuring proper disposal, and replacing single-use devices with reusables are crucial for environmental and economic benefits.

Conclusions:

• Substantial opportunities exist to enhance the environmental sustainability of anesthesia.
• Implementing eco-friendly practices in anesthesia is critical given the escalating climate crisis.
• Thoughtful waste segregation in operating rooms can reduce energy-intensive processing of medical waste.
