Clinical TrialBrachial plexus birth injuries: anaesthesia for surgical nerve reconstruction and preoperative myelography and computed tomographic myelography.
Surgical nerve reconstruction for brachial plexus birth injuries and preoperative myelography and computed tomographic (CT) myelography require special anaesthetic considerations. Anaesthesia and medical records were retrospectively reviewed for the infants who underwent myelography, CT myelography (n=37) and microsurgical nerve reconstruction (n=34) at our institution from January 1993 to August 1996. Anaesthetic considerations include long duration of operation, perioperative respiratory complications and plaster application which makes reintubation difficult. Myelography for diagnosis requires a specific positioning of the patient with the head fixed in a midline and prone position.

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 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 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 TrialThe effect of ketamine on 0.25% and 0.125% bupivacaine for caudal epidural blockade in children.
Forty boys aged from one to five years undergoing orchidopexy were randomly allocated to receive one of two solutions for caudal epidural injection. Group A received 1 ml.kg-1 of 0.125% bupivacaine with ketamine 0.5 mg.kg-1 and Group B received 1 ml.kg-1 of bupivacaine 0.25% with ketamine 0.5 mg.kg-1. ⋯ The time taken to recover the ability to walk was a median of two h in Group A and three h in Group B (P<0.05). There were no differences between the groups in the incidence of urinary retention or postoperative sedation.
