Randomized Controlled Trial Multicenter Study Clinical Trial
Bispectral index monitoring to prevent awareness during anaesthesia: the B-Aware randomised controlled trial.
BIS monitoring significantly reduces the risk of awareness under general anesthesia in high-risk adult surgical patients.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Sevoflurane for interventional neuroradiology procedures is associated with more rapid early recovery than propofol.
Sevoflurane and propofol are both suitable for neuroanesthesia but have not previously been compared as maintenance agents for long duration (one to five hours) procedures. ⋯ The use of sevoflurane for maintenance of anesthesia for prolonged neuroradiological procedures is associated with more rapid early recovery than propofol and is associated with similar side effects. Sevoflurane and propofol can both be recommended for these procedures. The clinical benefit of the more rapid recovery with sevoflurane is unknown.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Conventional stepwise vs. vital capacity rapid inhalation induction at two concentrations of sevoflurane.
A multicentre study was conducted to compare three methods of inhalation induction with sevoflurane in adult premedicated patients. ⋯ Inhalation induction of anaesthesia with sevoflurane with the three techniques tested is safe, reliable and well accepted by the patients. The vital capacity rapid inhalation group primed with sevoflurane 8% was the fastest method with no relevant side-effects.

Multicenter Study
The Patient State Index as an indicator of the level of hypnosis under general anaesthesia.
This retrospective study describes the performance of the Patient State Index (PSI), under standard clinical practice conditions. The PSI is comprised of quantitative features of the EEG (QEEG) that display clear differences between hypnotic states, but consistency across anaesthetic agents within the state. ⋯ The PSI, based upon derived features of brain electrical activity in the anterior/posterior dimension, significantly co-varies with changes in state under general anaesthesia and can significantly predict the level of arousal in varying stages of anaesthetic delivery.

Multicenter Study Clinical Trial
Ophthalmic regional anesthesia: medial canthus episcleral (sub-tenon) single injection block.
The purpose of this study was to evaluate the efficacy and safety of episcleral single-injection anesthesia in a large number of patients. ⋯ This is the first survey of a large experience in episcleral single-injection anesthesia, a form of anesthesia that does not preclude sharp-needle complications and does require training. Only one complication occurred among 2,031 patients; however, a larger number of patients is needed to definitively evaluate the safety of episcleral single-injection anesthesia.
