New halogenated agents: should I change my practice?

Sevoflurane and Desflurane are relatively new halogenated agents which make induction and control of depth of anaesthesia easier, recovery rapid and of good quality and they have less side-effects and toxicity. In children sevoflurane could replace halothane because it provides smooth and rapid induction with less cardiovascular depression and arrhythmias. Desflurane is not used because of its pungent odour. In adults sevoflurane could be preferred to desflurane because it allows rapid induction and laryngeal mask insertion or tracheal intubation without myorelaxants, a similar time of recovery, no clinical evidence for renal and hepatic toxicity, no more costs for anaesthesia for a lower MAC.
