Randomized Controlled Trial
Optimal effective concentration of ropivacaine for postoperative analgesia by single-shot femoral-sciatic nerve block in outpatient knee arthroscopy.
To compare analgesic and mobility effects of different ropivacaine concentrations in femoral-sciatic nerve block, for postoperative analgesia in knee arthroscopy. ⋯ The 0.20% ropivacaine dose for femoral-sciatic nerve block in knee arthroscopy provided satisfactory postoperative analgesia, while preserving ability of motion.

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.

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.
