UnlabelledThe volatile agent sevoflurane enables a rapid emergence from anaesthesia. The aim of this study was to investigate the possibility of increasing turnover in pediatric anaesthetic cases by use of sevoflurane in comparison with halothane. Often short cases or day cases need rapid turnover.Methods And PatientsThe pediatric patients aged 4-14 years (ASA I) presenting for elective ophthalmic surgery were randomised to either the halothane or the sevoflurane group. Standard monitoring was applied to all patients, in addition the pEEG was used to determine comparable anaesthetic depth. Sevoflurane or halothane were titrated to a SEF 90 of 8-12 Hz. Management of the airway was done with the RLMA (reinforced laryngeal mask). All patients were under controlled ventilation. At the end of surgery and anaesthesia 3 time intervals were measured: phase I) end of anaesthetic application--start of spontaneous respiration; phase II) start of spontaneous respiration--removal of RLMA. The SEF 90 interval was also assessed.Results18 cases were included (halo n = 8/sevo n = 10, no significant differences concerning weight, age, anaesthesia time). There is a significant advantage for the Sevoflurane group in phase II of 6.8 minutes. No differences were seen in phase I and SEF 90 interval.ConclusionSevoflurane offers the potential for shortening turnover in pediatric anaesthesia.
