Are there randomised controlled trials on sevoflurane?
['After Ethics Review Board approval, 44 ASA I-III patients undergoing elective gynaecological surgery were randomised after surgery to either hypercapnic hyperpnoea or control groups.', 'Hypercapnic hyperpnoea in spontaneously breathing patients halves the time of recovery from sevoflurane-induced anaesthesia in the operating room.', 'A total of 200 women undergoing first trimester abortion (American Society of Anesthesiologists physical status I) participated in the study. Patients were randomly assigned to receive either sevoflurane or propofol for short-term sedation.', 'The results showed the incidence of dreaming was significantly different between anaesthesia groups with 60% (60/100) of the sevoflurane group and 33% (33/100) of the propofol group (P=0.000)', 'Anaesthesia administered had no effect on patient satisfaction. The results suggest that the incidence of dreaming was not affected by recovery time. Patient satisfaction was not influenced by choice of sedative and/or by the occurrence of dreaming during sevoflurane or propofol short-term sedation.', 'Prior reports suggest that dreaming during anaesthesia is dependent on recovery time. Dreaming during sedation may impact patient satisfaction', 'Sevoflurane vs. propofol in patients with coronary disease undergoing mitral surgery: a randomised study.', 'We therefore performed a randomised controlled trial (sevoflurane vs. propofol) to compare cardiac troponin release in patients with coronary disease undergoing mitral surgery.', 'Myocardial injury in remifentanil-based anaesthesia for off-pump coronary artery bypass surgery: an equipotent dose of sevoflurane versus propofol', 'This randomised controlled trial compared the effect of equipotent anaesthetic doses of sevoflurane (S group) versus propofol (P group), during remifentanil-based anaesthesia for off-pump coronary artery bypass surgery, on myocardial injury. Either sevoflurane or propofol was titrated to maintain bispectral index values between 40 and 50.', 'This randomised, multicentre, parallel-group trial included 98 adult patients. Patients received intravenous propofol for induction followed by sevoflurane maintenance anaesthesia.', 'Patients were randomly allocated to receive sugammadex 2.0 mg kg(-1) or neostigmine 50 microg', 'We compared the haemodynamics, emergence and recovery characteristics of total intravenous anaesthesia using propofol/remifentanil with sevoflurane/remifentanil anaesthesia, under bispectral index guidance, in 103 patients undergoing surgical procedures lasting > 3.5 h', 'A randomised controlled trial of paediatric conscious sedation for dental treatment using intravenous midazolam combined with inhaled nitrous oxide or nitrous oxide/sevoflurane', 'Intravenous midazolam, especially in combination with inhaled nitrous oxide or sevoflurane and nitrous oxide, are effective techniques, with the combination of midazolam and sevoflurane the one most likely to result in successful treatment.', 'We randomly assigned 1063 adult and 322 paediatric elective patients to one of four (adult) or two (paediatric) anaesthesia groups', 'In both studies, there was no difference in postdischarge outcomes at Day 7. Sevoflurane/sevoflurane was more costly with higher PONV rates in both studies. In adults, the cost per extra episode of PONV avoided was pound 296 (propofol/propofol vs. propofol/ sevoflurane) and pound 333 (propofol/sevoflurane vs. propofol/isoflurane).', 'Comparison of sevoflurane and nitrous oxide mixture with nitrous oxide alone for inhalation conscious sedation in children having dental treatment: a randomised controlled trial.', 'We studied 411 children aged 3-10 years who were referred for dental treatment. They were randomly allocated to have inhalation conscious sedation with either sevoflurane/nitrous oxide mixture or nitrous oxide alone']
['Yes. There are < 10 studies reported, answering questions like : how to improve speed of recovery, relationship to dreaming and anesthetic experience, effect on cardiac troponin release, effect on myocardial injury, postoperative delirium,  haemodynamics & emergence and recovery characteristics of total intravenous anaesthesia,  costs of postoperative nausea and vomiting, pediatric conscious sedation for dental procedures']
