Common anesthetic is a greenhouse gas, but doctors are turning to safer -- and cheaper -- alternative

Sevoflurane is one of the most commonly used anesthesiology gases. The other big one is desflurane. Whichever gas a patient gets is inhaled, but only about 5% is metabolized. The rest is exhaled and sucked into a ventilation system. But that can damage the environment.
