Randomized Controlled Trial Multicenter Study Clinical TrialOndansetron reduces nausea and vomiting after paediatric adenotonsillectomy.
The efficacy, safety and resource implications of a single intravenous dose of ondansetron (0.1 mg.kg-1, maximum 4 mg) were assessed in a multinational, multicentre, randomized, double-blind, placebo-controlled trial of 427 children aged 1-12 years, undergoing tonsillectomy with/without adenoidectomy. Emesis (retching and/or vomiting) and nausea were analysed separately. Significantly more ondansetron-treated children had no episodes of emesis (127/212 (60%) vs 100/215 (47%); P = 0.004) and experienced no postoperative nausea (135/211 (64%) vs 108/213 (51%); P = 0.004) in the first 24 h. ⋯ Significantly fewer ondansetron-treated children were rescued or withdrawn from the study (5% vs 10%; P = 0.042). Fewer ondansetron-treated patients required nursing intervention (34% vs 45%; P = 0.007) and the average intervention time was significantly shorter (4.6 vs 8.1 minutes; P = 0.001). Resources used to manage PONV were significantly reduced by ondansetron (43% vs 57%; P = 0.014).

Randomized Controlled Trial Comparative Study Clinical TrialPropofol infusion vs thiopentone/isoflurane anaesthesia for prominent ear correction in children.
Postoperative nausea and vomiting (PONV) frequently follows prominent ear correction under general anaesthesia in children. In a prospective, single-blind study, we compared the incidence of PONV after propofol infusion anaesthesia with that following thiopentone induction and isoflurane maintenance in 30 children aged from four to 14 years randomly allocated to one of two groups. All the children were mechanically ventilated. ⋯ One child receiving propofol (group P) complained of nausea, compared with eight receiving thiopentone/ isoflurane, (group T) (P = 0.005), while three children in group P and ten in group T vomited before hospital discharge, (P = 0.01). Eight children in group P were considered to be fit for discharge on the day of surgery as against four in group T, (not significant). Only four out of twelve children receiving opioid analgesia vomited.

Randomized Controlled Trial Clinical TrialPostoperative analgesia with preoperative oral ibuprofen or acetaminophen in children undergoing myringotomy.
Previous studies have shown over 70% of children require analgesics following bilateral myringotomy and tube placement (BM&T). This double-blind, placebo-controlled study compared the postoperative analgesic effects of preoperatively administered oral acetaminophen or ibuprofen. Forty three ASA I or II children age six months or older scheduled for elective BM&T were randomized to receive acetaminophen (paracetamol) 15 mg.kg-1, ibuprofen 10 mg.kg-1, or placebo. ⋯ CHEOP scores did not differ between the groups at any time. There was no difference in the number of children receiving rescue analgesia. This study showed no benefit of preoperatively administered oral ibuprofen 10 mg.kg-1 or acetaminophen 15 mg.kg-1 over placebo for the relief of postoperative pain in children undergoing BM&T.

Randomized Controlled Trial Clinical TrialOral premedication with midazolam in paediatric anaesthesia. Effects on sedation and gastric contents.
The aim of this study was to assess oral premedication with midazolam in paediatric anaesthesia. Sedation, quality of induction, recovery time, acceptance and effects on gastric contents were analysed. This prospective, double blind, at random and controlled study was performed in 107 children, aged between three and ten years. ⋯ The recovery time was similar for the two groups. There were no statistically significant differences in gastric pH or residual volume among the three groups. It is concluded that midazolam given by mouth is an efficient and safe drug for premedication in paediatric anaesthesia.

Randomized Controlled Trial Comparative Study Clinical TrialA comparison of thiopentone-isoflurane anaesthesia vs propofol infusion in children having repeat minor haematological procedures.
We have performed a randomized, cross over study in 22 children suffering from acute leukaemia, who underwent repeated anaesthesia for bone marrow aspiration and lumbar puncture. For their first anaesthetic, the children (aged 3-10 years old) received, either a thiopentone/isoflurane anaesthetic or intravenous propofol, both supplemented with nitrous oxide. On a second occasion they received the alternative technique. ⋯ Twenty-seven per cent had no preference. There was no significant difference in length of anaesthetic time (P = 0.07) or the time taken for recovery (P = 0.17) between the two groups. There was a large individual variation in propofol requirements and movement was common during stimulation of patients in this group, though this did not adversely affect the surgical procedure.
