Background: The use of N2O during low-flow anesthesia (LFA) causes difficulty in predicting inspired gas mixtures and oxygen concentration due to accumulation. An alternative technique, which uses a mixture of oxygen and air and a morphine infusion to replace N2O, has been evaluated in children during LFA, and the clinical effects and composition of gases in the system are presented here.
