The concentration of sevoflurane being delivered from a vaporizer during anesthesia should be known. This may be accomplished by using a vaporizer calibrated specifically for sevoflurane. The administration of general anesthesia must be individualized based on the patient’s response.
Replacement of desiccated CO₂ absorbents:
When a clinician suspects that the CO₂ absorbent may be desiccated, it should be replaced. The exothermic reaction that occurs with sevoflurane and CO2 absorbents is increased when the CO₂ absorbent become desiccated, such as after an extended period of dry gas flow through the CO₂ absorbent canisters.
Pre-anesthetic medication:
Pre-medication should be selected according to the needs of the individual patient, and at the discretion of the anaesthetist.
Induction:
Sevoflurane has a non-pungent odor and does not cause respiratory irritability; it is suitable for mask induction in pediatrics and adults. Sevoflurane is given in concentrations of up to 5% in adults and 8% in children, with oxygen or a mixture of oxygen and nitrous oxide. Induction with sevoflurane is rapid (surgical anaesthesia in less than 2 minutes).
Maintenance:
Surgical levels of anesthesia can usually be achieved with concentrations of 0.5 – 3% sevoflurane with or without the concomitant use of nitrous oxide. Sevoflurane can be administered with any type of anesthesia circuit.
