Randomized Controlled Trial Comparative Study Clinical Trial
Increased success rate with infraclavicular brachial plexus block using a dual-injection technique.
To test the hypothesis that dual injection of the local anesthetic in coracoid infraclavicular brachial plexus block might enhance both sensory and motor block for anesthesia of the upper limb when compared with a single-injection technique. ⋯ Dual injection of local anesthetic guided by nerve stimulator increases the efficacy of coracoid block when compared with a single injection of the same dose of local anesthetic.

Randomized Controlled Trial Comparative Study Clinical Trial
Rapid sevoflurane induction compared with thiopental.
To examine whether the speed of induction of anesthesia with sevoflurane/nitrous oxide (N2O) utilizing a 10-second vital capacity rapid inhalation induction (VCRII) followed by tidal breathing was similar or faster than cautious intravenous (i.v.V) thiopental induction with inhaled N2O. ⋯ Sevoflurane/N2O VCRII as used in this investigation is an effective inhalation technique; it resulted in an induction time similar to that of slow i.v. thiopental with inhaled N2O.

Randomized Controlled Trial Comparative Study Clinical Trial
Remifentanil used to supplement propofol does not improve quality of sedation during spontaneous respiration.
To evaluate whether the use of remifentanil to supplement propofol during spontaneous respiration confers any benefits in terms of quality of sedation and recovery, or in terms of reduction in propofol requirements. ⋯ The addition of remifentanil to propofol during spontaneous ventilation offered no benefits compared with the use of propofol alone.

Randomized Controlled Trial Comparative Study Clinical Trial
A prospective, randomized, double-blinded comparison of ropivacaine 0.5%, 0.75%, and 1% ropivacaine for peribulbar block.
To evaluate the efficacy of three different concentrations of ropivacaine (0.5%, 0.75%, and 1%) together with a single concentration of hyaluronidase administered for peribulbar block. ⋯ While confirming that ropivacaine is a good option for peribulbar anesthesia, this study demonstrated that the use of 0.75% or 1% concentrations are preferred in that they produce quick and deep sensory and motor block of the operated eye. If recovery of normal motor function is important after surgery, the 0.75% concentration probably represents the best compromise.

Randomized Controlled Trial Comparative Study Clinical Trial
Laryngeal mask airway versus endotracheal tube for outpatient surgery: analysis of anesthesia-controlled time.
To show that efficiency of operating room times can be improved significantly using rapid changes between operative procedures. ⋯ The clinical relevance of reduced anesthesia induction time using LMA is questionable. The lack of difference in emergence time could be a result of the use of total intravenous anesthesia.
