Case ReportsExtracorporeal circulatory support in near-fatal flecainide overdose.
Flecainide, a class 1c antiarrhythmic, has a high mortality associated with significant overdose. We report the case of a 20-year-old female who took approximately 4 grams of flecainide and a small amount of paracetamol as an impulsive gesture. Circulatory failure unresponsive to pacing, inotropes and sodium bicarbonate was successfully treated with cardiopulmonary bypass (CPB). ⋯ Ischaemic renal dysfunction manifested early in her admission and required haemodiafiltration. Despite a prolonged period of unresponsiveness and pupillary dilatation during resuscitation and CPB she made a full recovery. We believe this is the first reported case of flecainide overdose, requiring extracorporeal circulatory support, not resulting in neurological deficit.

Comparative StudyPatient referral and transportation to a regional tertiary ICU: patient demographics, severity of illness and outcome comparison with non-transported patients.
A descriptive analysis and comparison of critically ill transported patients with non-transported patients will assist in selecting the appropriate referral and transportation process and subsequent incorporation into the critical care services of receiving hospitals. A retrospective review of transported and non-transported patients admitted to the same Intensive Care Unit was conducted. ⋯ Transported patients had a different case mix, significantly higher severity of illness measures, mortality and length of ICU stay. Observed mortality of transported patients with sepsis, gastrointestinal disease or bleeding, intracranial haemorrhage and post respiratory arrest was less than predicted whilst those with neurological disease, post cardiac arrest and overdose had a higher than predicted mortality.

Case ReportsFailed intubation in the intensive care unit managed with laryngeal mask airway and percutaneous tracheostomy.
We report the management of failed intubation in a critically ill, hypoxic and catabolic patient with sepsis and acute lung injury. Insertion of a laryngeal mask airway restored ventilation and corrected hypoxia. As the laryngeal mask provides only a temporary airway, it was essential to secure the airway by percutaneous tracheostomy to initiate mechanical ventilation.

Undernutrition in children--effect on vecuronium induced neuromuscular blockade.
Sixty children aged one to 12 years requiring anaesthesia including a muscle relaxant were assessed for their nutritional status based on simple anthropometric and biochemical parameters. They were allocated to one of four groups: normal nutrition, mild, moderate or severe malnutrition. The neuromuscular effects of vecuronium bromide 0.1 mg/kg were studied by recording evoked responses to train of four (TOF) nerve stimulation using an accelerograph. ⋯ The duration of action of the initial dose was 26.5, 24.0, 17.7 and 13.3 minutes and the mean duration of action of top-up doses was 16.2, 14.9, 11.2 and 8.9 minutes respectively. Reversal time with neostigmine 0.05 mg/kg was not significantly different in the four groups. These results demonstrate a statistically significant delay in onset and shortening of the duration of action of vecuronium in the undernourished groups compared with the normal nutrition group when vecuronium is administered to children on a milligram per kilogram basis.

Case ReportsManagement of a pregnant patient with airway obstruction secondary to goitre.
A case of airway obstruction in advanced pregnancy is presented. The patient was successfully managed with an awake fibreoptic intubation performed orally followed by a caesarean section and thyroidectomy as a combined procedure. On resection, a thyroid gland weighing 370 g was removed. The patient made an uneventful recovery.
