Randomized Controlled Trial Comparative Study Clinical TrialSevoflurane versus propofol for induction and maintenance of anaesthesia with the laryngeal mask airway in children.
We compared patient outcomes for propofol vs sevoflurane with the laryngeal mask airway (LMA) using either spontaneous breathing (SB) or pressure controlled ventilation (PCV). One hundred and twenty children undergoing minor surgery below the umbilicus were randomly assigned to receive either (1) propofol 3 mg.kg-1 followed by a maintenance infusion of 5 mg.kg-1.h-1, or (2) induction with sevoflurane 7% followed by maintenance with 1.7%. Following LMA insertion, patients were given atracurium and underwent PCV if surgery was expected to last > or = 30 min. ⋯ Patient outcome was similar for the SB and PCV groups. We concluded that the techniques described here using propofol and sevoflurane are equally suitable for induction and maintenance of anaesthesia with the LMA in children undergoing minor surgery below the umbilicus. Emergence is more rapid, but postoperative agitation more common with sevoflurane.

Randomized Controlled Trial Comparative Study Clinical TrialCombination of granisetron and droperidol for the prevention of vomiting after paediatric strabismus surgery.
This study was undertaken to compare the efficacy of granisetron plus droperidol with each antiemetic alone for the prevention of vomiting after paediatric strabismus surgery. In a prospective, randomized, double-blinded trial, 120 ASA physical status I children, aged 4-10 years, received granisetron 40 microg.kg- 1, droperidol 50 microg.kg- 1, granisetron 40 microg.kg- 1 plus droperidol 50 microg.kg- 1 (n=40 of each) intravenously after an inhalation induction of anaesthesia. ⋯ No clinically important adverse events were observed in any of the groups. In conclusion, a combination of granisetron and droperidol was more effective than granisetron or droperidol as a sole antiemetic for the prevention of postoperative vomiting in children undergoing strabismus repair.

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 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.
