Case ReportsLacticacidosis after short-term infusion of propofol for anaesthesia in a child with osteogenesis imperfecta.
We describe the case of a 7-year-old boy with osteogenesis imperfecta, who underwent anaesthesia with propofol-fentanyl-nitrous oxide-suxamethonium for orthopaedic surgery of a distal femur fracture. He developed lacticacidosis after short-term propofol infusion (150 min, mean infusion rate 13.5 mg.kg-1.h-1) associated with a prolonged recovery time without serious haemodynamic changes. ⋯ There was no significant increase in body temperature. The boy fully recovered.

Randomized Controlled Trial Comparative Study Clinical TrialPretreatment with intravenous ketamine reduces propofol injection pain.
Paediatric procedural sedation using propofol has been shown to be safe and effective and is widely used. Pain at the injection site is a frequent complaint and can be particularly distressing for children, especially for those undergoing repeated procedures. Ketamine has analgesic properties and can diminish the incidence of propofol infusion pain in adults. The aim of the study was to investigate whether pretreatment with ketamine would reduce infusion line pain in propofol sedation in children. ⋯ Pretreatment with ketamine (0.5 mg.kg-1) is very effective in preventing propofol infusion pain.

Sotos syndrome is a rare condition characterized by typical facies, early accelerated growth, large body size, developmental delay and congenital heart defects. Reports of anaesthetic management of these children are very rare. ⋯ The child had a marked developmental delay, hypotonia and mitral regurgitation. The key points in the management of anaesthesia in Sotos syndrome are discussed.

Case ReportsProlonged cannulation of the left internal mammary artery (LIMA) for blood pressure monitoring in a child after cardiopulmonary bypass.
Cannulation of the radial artery percutaneously or by cut down is frequently used to monitor blood pressure in infants and children undergoing cardiopulmonary bypass. When radial artery cannulation is difficult because of previous cannulation attempts, and/or surgical cut downs, posterior tibial artery cannulation is sometimes undertaken. ⋯ There were no complications with the placement and/or the removal of this arterial line on the 25th postoperative day. When standard arterial monitoring sites are not accessible, internal mammary artery cannulation can provide reliable access for prolonged arterial blood pressure monitoring in the postoperative period in children.

Anaesthesia for magnetoencephalography in children with intractable seizures.
Magnetoencephalography (MEG), a noninvasive technique for evaluation of epileptic patients, records magnetic fields during neuronal electrical activity within the brain. Anaesthesia experience for MEG has not yet been reported. ⋯ In our experience, midazolam premedication resulted in a high MEG failure rate (73%). Chloral hydrate premedication and propofol maintenance resulted in a lower incidence of MEG failure (5.8%). General anaesthesia with a continuous infusion of propofol or sevoflurane appears acceptable, although, lighter levels of anaesthesia might be required to avoid interference with interictal activity of the brain.
