Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialA comparison of sevoflurance to halothane in paediatric surgical patients: results of a multicentre international study.
Induction, emergence and recovery characteristics were compared during sevoflurane or halothane anaesthetic in a large (428) multicentre, international study of children undergoing elective inpatient surgical procedures. Two hundred and fourteen children in each group underwent inhalation induction with nitrous oxide/oxygen and sevoflurane or halothane. Incremental doses of either study drug were added until loss of eyelash reflex was achieved. ⋯ Mean maximum inorganic fluoride concentration was 18.3 microM.l-1. The fluoride concentrations peaked within one h of termination of sevoflurane anaesthetic and returned rapidly to baseline within 48 h. This study suggests that sevoflurane may be the drug of choice for the anaesthetic management of children.

Randomized Controlled Trial Comparative Study Clinical TrialPosttonsillectomy vomiting. Ondansetron or metoclopramide during paediatric tonsillectomy: are two doses better than one?
This randomized, double blinded, placebo controlled, prospective study compared the anti-emetic efficacy of one preoperative dose of metoclopramide 0.25 mg.kg-1 intravenously or ondansetron 0.15 mg.kg-1 intravenously with two doses of the same drugs (second dose administered one h postoperatively) in 200 preadolescent children undergoing tonsillectomy with either isoflurane or propofol anaesthesia. The incidence of posttonsillectomy vomiting was significantly reduced (P < 0.005) by two doses of either metoclopramide or ondansetron (18% and 8%, respectively) compared with placebo (50%). No difference in posttonsillectomy vomiting exists between the children who received isoflurane and those who received a propofol infusion. Our results suggest that two doses of metoclopramide 0.25 mg.kg-1 intravenously, like two doses of ondansetron 0.15 mg.kg-1, are effective in reducing vomiting after tonsillectomy in children who have received either isoflurane or propofol anaesthesia.

Deep sedation with propofol in preschool children undergoing radiation therapy.
Immobilization of children undergoing radiation therapy always requires anaesthesia. Deep sedation with continuous infusion of propofol and spontaneous breathing, (we call it ¿sedative anaesthesia'), may be an alternative to general anaesthesia with intubation and controlled ventilation. This clinical report deals with 155 anaesthetics performed in 11 consecutive paediatric oncology patients, mean age 30 months (range 19-42), who required radiation therapy for from seven to 33 consecutive days. ⋯ Children opened their eyes spontaneously four ( +/- 3.7) min after discontinuing the propofol infusion and could be discharged about 30 mins later. Tachyphylaxis or unpleasant side effects during and after anesthesia have not been observed. Sedative anaesthesia with propofol seems to be an excellent method to immobilize paediatric patients during radiotherapeutic procedures.

Randomized Controlled Trial Clinical TrialOral midazolam premedication for paediatric day case patients.
Forty-nine children having day-stay surgical procedures were randomly assigned to receive oral midazolam 0.75 mg.kg-1 or placebo in a double blind fashion. The child's level of anxiety was assessed before premedication using parental, child and observer scales. The child and observer anxiety scores were repeated in the anaesthetic room. ⋯ Observer scores decreased in the midazolam group (P < 0.02), but not in the placebo group, children below six years having the greatest decrease with midazolam. The median time to discharge from hospital was delayed by 30 min in the midazolam group (P < 0.01). Children do not require routine sedative premedication for day case procedures, but oral midazolam is useful in producing calm behaviour in those children with high observer anxiety scores.

Randomized Controlled Trial Comparative Study Clinical TrialComparison of diclofenac and tenoxicam for postoperative analgesia with and without fentanyl in children undergoing adenotonsillectomy or tonsillectomy.
127 children scheduled for elective tonsillectomy or adenotonsillectomy were studied. Anaesthesia was induced with propofol and maintained with a volatile agent. At induction the child received either rectal diclofenac 1 mg.kg-1 with or without fentanyl 0.75 microgram.kg-1 i.v., or intravenous tenoxicam 0.4 mg.kg-1 with or without fentanyl 0.75 microgram.kg-1 i.v. ⋯ Pain scores in the tenoxicam without fentanyl group were significantly higher in recovery (P < 0.05) than the diclofenac group without fentanyl and both fentanyl groups. This group required supplemental analgesia earlier although this was not significant. The pain scores in the diclofenac with fentanyl group were significantly lower at one h and four h than the group receiving diclofenac alone (P = 0.008 and 0.02 respectively).
