Randomized Controlled Trial
Association between bispectral index and age and use of sedative drugs in high spinal anaesthesia.
A prospective, randomized, double-blind study using bispectral index values to objectively quantify the sedative effect of high spinal anaesthesia in patients stratified according to age, and to determine whether sedative drugs are associated with additional adverse respiratory and haemodynamic effects in older patients. ⋯ The sedative effect of high spinal anaesthesia is greater in older patients than in younger patients, with an increase in respiratory instability.

Randomized Controlled Trial
Low concentrations of lidocaine for inguinal hernia repair under local infiltration anaesthesia.
A randomized, double-blind, prospective, controlled study to determine the lowest concentration of lidocaine that provides satisfactory anaesthesia and analgesia for inguinal hernia repair. ⋯ The mean dose of lidocaine consumed in group A was significantly lower but exerted similar efficacy to that in the other groups, and may lead to a lower risk of local anaesthetic toxicity.

Meta Analysis Comparative Study
Complications following dorsal versus volar plate fixation of distal radius fracture: a meta-analysis.
A meta-analysis to compare complication rates following volar or dorsal surgical fixation of distal radius fracture. ⋯ Dorsal fixation offers a lower risk of neuropathy and carpal tunnel syndrome than the volar approach, but a higher risk of tendon irritation. Patients with a distal radius fracture can expect similar outcomes after volar or dorsal surgery.

Little is known about the impact of cerebral microbleeds on cognitive function. This study investigated the distribution of cerebral microbleeds and their impact on cognitive function, in patients with lacunar infarct. ⋯ The number and location of cerebral microbleeds were both closely associated with cognitive impairment, in patients with lacunar infarct.

To investigate prospectively the rate of, and factors influencing, delayed extubation following infratentorial craniotomy in a Chinese neurosurgical centre. ⋯ Brain stem and lower cranial nerve function were the main factors affecting extubation decision-making. Further research is required, to establish criteria for delayed extubation following infratentorial craniotomy.
