The aim of this study was to describe topographic variations in the arrangement of the four main brachial plexus nerves at the junction of the axilla and the upper part of the arm. ⋯ Topographic variations of the four main nerves at the axilla were found to be numerous, the most frequent arrangement being seen in less than two-thirds of the patients. Four separate nerves were seen on static ultrasound imaging at this sectional level of the axilla in only 78% of the cases.

The implementation of the European Working Time Directive (WTD) has reduced the hours worked by trainees in the UK to a maximum of 56 h per week. With a further and final reduction to 48 h per week scheduled for August 2009, there is concern amongst doctors about the impact on training and on patient care. Paediatric anaesthesia is one of the specialist areas of anaesthesia for which the Royal College of Anaesthetists (RCoA) recommends a minimum caseload during the period of advanced training. ⋯ Since the implementation of the WTD, there has been a significant reduction in the number of cases performed by SpRs in paediatric anaesthesia and they are no longer achieving the RCoA recommended minimum numbers for advanced training.

Randomized Controlled Trial
Magnesium sulphate attenuates arterial pressure increase during laparoscopic cholecystectomy.
Magnesium is well known to inhibit catecholamine release and attenuate vasopressin-stimulated vasoconstriction. We investigated whether i.v. magnesium sulphate attenuates the haemodynamic stress responses to pneumoperitoneum by changing neurohumoral responses during laparoscopic cholecystectomy. ⋯ I.V. magnesium sulphate before pneumoperitoneum attenuates arterial pressure increases during laparoscopic cholecystectomy. This attenuation is apparently related to reductions in the release of catecholamine, vasopressin, or both.

Randomized Controlled Trial Multicenter Study
Cognitive aid for neonatal resuscitation: a prospective single-blinded randomized controlled trial.
Retention of skills and knowledge after neonatal resuscitation courses (NRP) is known to be problematic. The use of cognitive aids is mandatory in industries such as aviation, to avoid dependence on memory when decision-making in critical situations. We aimed to prospectively investigate the effect of a cognitive aid on the performance of simulated neonatal resuscitation. ⋯ Retention of skills after NRP training is poor. The infrequent use of the cognitive aid may be the reason that it did not improve performance. Further research is required to investigate whether cognitive aids can be useful if their use is incorporated into the NRP training.
