Randomized Controlled Trial Comparative Study Clinical TrialAlfentanil for intubation under halothane anaesthesia in children.
Intubating conditions under halothane anaesthesia aided with alfentanil 20 micrograms.kg-1 were compared with suxamethonium 2 mg.kg-1 in 40 children presenting for day dental procedures. The condition of vocal cords, jaw relaxation and presence of movement and coughing were scored to give the overall intubating conditions. ⋯ The cardiovascular response to intubation was attenuated in the alfentanil group. Some 43.7% of those receiving suxamethonium developed myalgia the day after surgery compared with 0% in the alfentanil group (P < 0.01).

Randomized Controlled Trial Comparative Study Clinical TrialPropofol-nitrous oxide versus sevoflurane-nitrous oxide for strabismus surgery in children.
Vomiting is a common problem following strabismus surgery. We compared the effects of propofol-N2O and sevoflurane-N2O on the incidence of oculocardiac reflex and postoperative nausea and vomiting. Forty unpremedicated children, aged 3-15 years were randomly assigned to two groups of 20 patients. ⋯ The overall incidence of vomiting and antiemetic requirement in the first 24 h was significantly higher in sevoflurane-N2O group than propofol-N2O group (P < 0.05). The propofol-N2O group had significantly more episodes of oculocardiac reflex than sevoflurane-N2O group (P < 0.05). Propofol-N2O anaesthesia results in a significantly lower incidence of postoperative vomiting, yet a significantly higher incidence of oculocardiac reflex.

Randomized Controlled Trial Clinical TrialIncidence and therapy of midazolam induced hiccups in paediatric anaesthesia.
A prospective, randomized and double blind study was undertaken to determine the incidence and a possible dose- or age-dependence of hiccups in children premedicated with rectal midazolam and to investigate the treatment of hiccups by intranasal ethyl chloride spray application. Two hundred ASA physical status 1 and 2 children, weighing 3.0 to 15.0 kg, scheduled for minor surgery, were randomly assigned to be given either 0.5 mg.kg-1 midazolam(n=100) or 1.0 mg. kg-1 midazolam (n=100) administered rectally. If hiccups were observed during a period of 20 min after premedication with midazolam, these children were treated after 3 min of hiccups with two short intranasal applications of ethyl chloride spray. ⋯ The mean age levels between children with or without hiccups were 5+/-9 months vs 21+/-19 months (P<0.01) in the 0.5 mg.kg-1 group and 6+/-7 months vs 20+/-14 months (P<0.01) in the 1.0 mg.kg-1 group. Intranasal application of ethyl chloride spray seems to be an effective therapy for midazolam induced hiccups in paediatric anaesthesia. The incidence of these hiccups is highly age significant, but not dose dependent.

Randomized Controlled Trial Comparative Study Clinical TrialComparison of morphine sulphate and codeine phosphate in children undergoing adenotonsillectomy.
We undertook a double-blind study to evaluate equianalgesic doses of intramuscular morphine sulphate (0.15 mg.kg-1) and codeine phosphate (1.5 mg.kg-1) in 40 healthy children undergoing adenotonsillectomy. There were no significant differences in pain scores, analgesic requirements or sedation scores between the two groups over the following 24 h. More children vomited in the morphine group (60%) than the codeine group (30%) between one and six h after the procedure (P < 0.05). Codeine phosphate is associated with less postoperative vomiting than morphine sulphate while providing comparable postoperative analgesia for adenotonsillectomy.

Randomized Controlled Trial Comparative Study Clinical TrialA comparison of halothane and isoflurane for gaseous induction of anaesthesia in infants.
Sixty-four ASA 1 and 2 infants between the ages of 44 weeks postconceptual age and one year presenting for routine, elective surgery were randomly anaesthetized with either 3% halothane in oxygen (Group H) or 5% isoflurane in oxygen (Group I). Patients in Group I took a mean (SD) time of 70.1(13.6) s to loss of eyelash reflex and 80.0 (13.5) s to tolerating the face mask, compared with 80.2 (17.7) s and 93.4 (20.5) s in Group H (P=0.028 and 0.0072, respectively). There were no significant differences between the groups for preinduction or induction state, lowest oxygen saturation, or the incidence of airway related complications or interventions. This study demonstrates that 5% isoflurane in oxygen induces anaesthesia in infants more quickly than 3% halothane in oxygen, without any increase in the incidence or severity of airway-related complications.
