Case ReportsFatal complication from central venous cannulation in a paediatric liver transplant patient.
We report a fatal complication from central venous cannulation in a child undergoing heterotropic liver transplantation. Following the attempted placement of a cannula in the left internal jugular vein, extravasation of blood products via the cannula resulted in haemothorax, hypotension and eventual brain death. Possible causes and strategies for prevention of this complication are discussed.

Computerized tomography of the lungs and arterial oxygen tension studies during apnoea in anaesthetized young lambs.
Computerized tomography (CT) of the lungs and arterial oxygen tension studies were performed during general anaesthesia in an animal model to understand changes in pulmonary atelectasis associated with anaesthesia in children during a 2 min apnoeic period. Six anaesthetized lambs were subjected to three periods of apnoea lasting 2 min each. ⋯ The results confirmed that significant background atelectasis was associated with general anaesthesia as found in adult human studies, but failed to demonstrate any increase in atelectasis during the period of induced apnoea. The decline in arterial oxygen tension in this study could be explained due to simple utilization of oxygen in keeping with physiological principles.

Analgesia following paediatric day-surgical orchidopexy and herniotomy.
We surveyed 90 boys, aged 1-13 years, who had undergone either orchidopexy or herniotomy, in a cohort study. Their pain and vomiting were assessed using a simple 4-point score in the Recovery Unit by the nursing staff, and at home by the parents. ⋯ Nearly one-third of the former group had moderate to severe pain at home, in contrast to less than one-tenth of children having herniotomy, who are also more likely to be painfree on the next day. We concluded that children having herniotomy can be treated adequately at home with paracetamol alone, whereas children having orchidopexy may require supplementation with stronger analgesics.

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.
