Case ReportsPersistent anaphylactic reaction after induction with thiopentone and cisatracurium.
A 6-year-old boy presented for surgery for phimosis. The anaesthetic technique included intravenous induction with thiopentone and neuromuscular blockade with cisatracurium. Severe persistent bronchospasm and central cyanosis followed the administration of these drugs. ⋯ Through increased serum eosinophil cationic protein, tryptase and histamine levels and IgE levels specific to cisatracurium, we demonstrated an IgE-mediated anaphylactic reaction to cisatracurium in the child's first exposure to this new neuromuscular blocking agent. Anaphylactic reactions to new anaesthetic drugs may be challenging to recognize and treat during general anaesthesia in children. The pathogenesis, diagnosis and management of life threatening persistent allergic reactions to intravenous anaesthetics are discussed.

The effect of propofol on intraoperative electrocorticography and cortical stimulation during awake craniotomies in children.
Propofol has been proposed as a sedative agent during awake craniotomies. However, there are reports of propofol suppressing spontaneous epileptiform electrocorticography (ECoG) activity during seizure surgery, while others describe propofol-induced epileptiform activity. The purpose of this study was to determine if propofol interferes with ECoG and direct cortical stimulation during awake craniotomies in children. ⋯ Cognitive, memory and speech testing was also successful. We conclude that propofol did not interfere with intraoperative ECoG during awake craniotomies. Using this technique, we were able to fully assess motor, sensory, cognitive, speech and memory function and simultaneously avoid routine airway manipulation.

The laryngeal mask airway in the difficult paediatric airway: an assessment of positioning and use in fibreoptic intubation.
The laryngeal mask airway (LMA) was used in 34 children who presented with difficult airways and difficulty in intubation. All 34 children were a grade 3 or grade 4 Cormack and Leehane view at conventional laryngoscopy. The laryngeal mask airway was used as part of the anaesthetic technique. ⋯ Of the 34 patients, 21 patients were intubated on 31 separate occasions. There were no failures. The complications of the fibreoptic intubation technique described are outlined.

Case ReportsDislodgement of bronchial foreign body during retrieval in children.
Foreign body aspiration is a leading cause of death in children aged less than 1 year. The removal of a foreign body poses a great challenge to the skill of the anaesthetist. Four cases are presented, analysing the part played by modes of respiration in the dislodgement of a bronchial foreign body during its retrieval.
