Randomized Controlled Trial Comparative Study
Efficacy and comparison of 0.5% levobupivacaine with 0.75% ropivacaine for peribulbar anaesthesia in cataract surgery.
The low cardiovascular and neurological toxicity of levobupivacaine has led to its application as a local anaesthetic in a wide variety of specialist applications including peribulbar block for cataract surgery. The aim of this study was to evaluate the efficacy of levobupivacaine 0.5% and to compare block quality vs. ropivacaine 0.75% in peribulbar anaesthesia. ⋯ Levobupivacaine (0.5%) has better anaesthetic properties with respect to 0.75% ropivacaine and is well-suited for peribulbar block in cataract surgery.

Randomized Controlled Trial
Feasibility of closed-loop titration of propofol guided by the Bispectral Index for general anaesthesia induction: a prospective randomized study.
This study was designed to evaluate the feasibility of propofol infusion by a closed-loop system for the titration of anaesthetic induction guided by Bispectral Index. ⋯ The system was able to allow induction clinically for all patients. Automated titration guided by Bispectral Index for propofol infusion was feasible without increase in haemodynamic adverse effects.

Randomized Controlled Trial
Efficacy of intrathecal adenosine for postoperative pain relief.
Adenosine, by intravenous and intrathecal routes, is known to alleviate various types of pain. However, the role of intrathecal adenosine in providing postoperative analgesia has not been confirmed. The aim of the present study was to evaluate the efficacy of intrathecal adenosine for postoperative pain relief, and to determine its role for pre-emptive analgesia. ⋯ Intrathecal adenosine 1,000 microg is not effective as an analgesic for postoperative pain relief, and there is no pre-emptive effect.
