A national quality improvement project in the UK revealed the environmental impact of nitrous oxide used in dental inhalation sedation. Researchers analyzed data from 31 dental services, finding that the mean carbon footprint per sedation appointment reached 28.62 kg of CO2 equivalent, highlighting significant variations in nitrous oxide supply methods. The study emphasized that while inhalation sedation is effective, with a national success rate of 92% among pediatric patients, dental services should monitor nitrous oxide usage and implement strategies to minimize wastage and reduce greenhouse gas emissions.
1. Nitrous oxide has a measurable environmental impact. 2. Mean carbon footprint per sedation appointment: 28.62 kg CO2 equivalent. 3. 84% use cylinder supply, 16% use piped systems. 4. Average nitrous oxide delivery duration: 28 minutes. 5. National success rate for nitrous oxide sedation: 92%. 6. Monitoring nitrous oxide use is essential for sustainability. 7. Emphasis on reducing flow rates without compromising clinical efficacy.
