Case ReportsCombination propofol-ketamine anaesthesia in sick neonates.
Two critically ill, opioid-tolerant neonates were anaesthetized using pancuronium and a mixture of propofol (PROP) and ketamine (KET). Three mg of KET were added per ml (10 mg) of PROP in a single syringe and infused at a rate of 100-150 microg x kg(-1) x min(-1) of the PROP component (30-45 microg x kg(-1) x min(-1) KET). ⋯ Both patients remained haemodynamically stable throughout their surgical procedures. PROP-KET is a rational and effective combination for intravenous anaesthesia in critically ill neonates who are likely to be opioid-tolerant when an anaesthesia vaporizer is not readily available.

Case ReportsA technique for maintenance of airway access in infants with a difficult airway following tracheal extubation.
Tracheal extubation of patients with a difficult airway represents a challenge to anaesthesiologists and intensive care physicians. While a variety of techniques designed to maintain access to the airway in case of the need for tracheal reintubation have been described in adults, no reports have been published in infants and young children. We describe an approach to this issue in a young child with severe micrognathia.

Case ReportsAnaesthetic management of an adolescent for scoliosis surgery with a Fontan circulation.
Advances in the treatment of congenital heart disease have led to a new group of adolescents or adults patients with cardiac anomalies. The anaesthetic management of these patients can be challenging especially when they are scheduled for major noncardiac surgery inducing haemodynamic instability. We report the case of a 14-year-old boy scheduled for posterior spinal fusion for idiopathic scoliosis who underwent a Fontan operation in infancy for pulmonary atresia with right ventricle hypoplasia. The preoperative investigations and the anaesthetic management are described.

Comparative Study Clinical Trial Controlled Clinical TrialEffect of oral midazolam premedication on the awakening concentration of sevoflurane, recovery times and bispectral index in children.
We sought to determine the influence of preoperative oral midazolam on: (i) measures of anaesthetic emergence; (ii) recovery times and (iii) intraoperative bispectral index (BIS) measurements during sevoflurane/N2O anaesthesia in paediatric patients. ⋯ There were no significant differences between groups in awakening time, sevoflurane or N2O awakening concentrations, time to PACU discharge, time to hospital discharge or in BIS I and BIS E measurements.

The pressures exerted on fragile structures in the infant during epidural injections have never been studied previously. ⋯ The residual pressures seem to vary more with the volume injected than the rate of injection or the pressures developed during the injection. The relationship between the rate of injection and pressures is significant when compared with adults where the pressures have been measured after an injection rate of 1 ml.s(-1) and 1 ml.5 s(-1). This is a very fast rate compared with our rates of injection of 1 ml over 1 and 2 min. Based on the findings of this study, we recommend a rate of 1 ml.2 min(-1) in infants. In neonates, a slower rate of injection would be preferable.
