オランダの三次病院で帝王切開50件を対象に、麻酔関連の薬剤と使い捨て製品のカーボンフットプリントを算定。平均5.6kg CO2-eq/件で、使い捨て製品が80%を占め、特に神経軸麻酔トレイ、注射器、保温ブランケットが主要因。未使用の使い捨て製品も約4%の影響。削減策として使い捨て製品の削減と廃棄物の最小化を提案。
English
This prospective study in a Dutch tertiary hospital calculated the carbon footprint of anaesthesia for 50 Caesarean deliveries. Mean footprint was 5.6 kg CO2-eq per delivery, with disposables contributing 80%, mainly from neuraxial trays, syringes, and warming blankets. Unused disposables accounted for ~4% of impact. Reducing disposable use and waste are key mitigation strategies.

📄 Abstract（原文）
Background The healthcare sector, particularly surgical care, is a major contributor to greenhouse gas emissions. This study aimed to investigate the carbon footprint of anaesthesia during Caesarean delivery, considering the impact of disposable products and pharmaceuticals, to identify environmental hotspots. Methods A prospective observational study was conducted in a Dutch tertiary hospital, based on 50 Caesarean deliveries between July and October 2025. The carbon footprint of anaesthesia pharmaceuticals and disposable products was calculated using estimated kilograms of carbon dioxide equivalents (kg CO 2 -eq) from life-cycle assessment data and for pharmaceuticals using active pharmaceutical ingredients from life-cycle inventory data. Results The mean carbon footprint of anaesthesia pharmaceuticals and disposable products was 5.6 kg CO 2 -eq per Caesarean delivery. Disposables accounted for 80% (4.5 kg CO 2 -eq) of the total footprint. The prepackaged neuraxial tray, syringes, and warming blanket were the largest contributors, and ∼4% of the impact stemmed from unused disposable products. Pharmaceuticals contributed 1.1 kg CO 2 -eq, with i.v. fluids, cefazolin, and i.v. paracetamol being the highest. Conclusions Disposable products were the main contributor to the carbon footprint of anaesthesia during Caesarean delivery. Addressing unnecessary use of disposable products is an achievable goal for reducing emissions. In addition, minimising wasted pharmaceuticals or unused disposable products is important, given that they significantly amplify the carbon footprint without providing clinical benefit.
