[Children need sustainability].

The reduction of greenhouse gases such as CO emissions and their equivalents (CO2e) generally has three aspects: Fugitive direct emissions (anesthetic gases, exhaust gases), indirect emissions through the purchase of energy (electricity, heat) and emissions in the supply chain (supply of consumables, disposal). Since pediatric anesthesia has a traditional affinity with inhalation, the use of anesthetic gases should be repeatedly questioned and, if possible, avoided on the way to net zero emissions in addition to general measures to conserve resources. In children, analgosedation, total intravenous anesthesia (TIVA) and establishment of venous access prior to the induction of anesthesia are particularly suitable for this purpose. In addition to avoiding greenhouse gases, the methods mentioned offer other significant medical advantages and can also be profitable in terms of safety and comfort. Nevertheless, anesthetic gases are required in pediatric anesthesia in some situations. For this reason, it is important to save anesthetic gases through minimal fresh gas flow and a rational approach to inhalation induction. To facilitate implementation in clinical practice, this article provides recommendations for mask induction and choice of anesthetic procedure.
