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.

Case ReportsProlonged somatosensory evoked potential depression following a brief exposure to low concentrations of inhalation anaesthetic in a 3-year-old child.
A 3-year-old child was brought to the operating room for removal of a brainstem juvenile pilocytic astrocytoma. Following inhalation induction and intubation, he was maintained on 0.5% isoflurane. Somatosensory evoked potentials (SSEPs) were recorded but unobtainable initially and up to 90 min after all inhalation agents were discontinued. ⋯ He returned to the operating room, was induced with propofol, and maintained with a propofol: nitrous oxide:fentanyl technique. This anaesthetic technique allowed adequate tumour resection with appropriate monitoring of SSEPs. These findings suggest that a total intravenous anaesthetic technique may be preferable for resection of spinal cord tumours where SSEPs are monitored.

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.

Remifentanil and propofol for sedation in children and young adolescents undergoing diagnostic flexible bronchoscopy.
Flexible fibreoptic bronchoscopy (FOB) has become a useful diagnostic and therapeutic procedure in children. We investigated 26 patients (3-14 years) for FOB using a new sedation strategy. All patients received oral premedication and inhalation of topical anaesthetic. ⋯ Endtidal CO2 concentration and arterial oxygen saturation remained stable throughout the study. All children were awake 5+/-1.3 min after stopping remifentanil infusion. Sedation with remifentanil/propofol is a new sedation strategy for diagnostic flexible paediatric bronchoscopy in children with spontaneous ventilation.

Clinical TrialThe effect of induced hypothermia on the duration of action of atracurium when given by infusion to critically ill children.
The aim of the study was to investigate the effect of induced hypothermia on the offset time of atracurium when given by continuous infusion to critically ill children. Over a period of 8 months, six mechanically ventilated children had a steady-state infusion of atracurium discontinued. The offset time of atracurium was assessed by train-of-four (TOF) stimulation of the ulnar nerve; recording the time taken to reach a TOF ratio of 0.9. ⋯ This was significantly longer than in patients with temperatures within the normal physiological range. When considering all assessments, performed both in hypothermic and normothermic patients, there is a strong correlation between rectal temperature and the offset time of atracurium. Prolonged moderate hypothermia has a very significant effect on the offset time of atracurium when given by infusion to critically ill children.
