Randomized Controlled Trial Clinical Trial
Saline-anesthetic interval and the spread of epidural anesthesia.
To examine the effect of modifying the interval between administration of saline used during the loss of resistance (LOR) method and local anesthetic on epidural anesthetic level and its quality. ⋯ The interval between the administration of saline and local anesthetic alters the anesthetic level and quality of epidural analgesia.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
A multicentre trial of ropivacaine 7.5 mg x ml(-1) vs bupivacaine 5 mg x ml(-1) for supra clavicular brachial plexus anesthesia.
To compare the efficacy of ropivacaine 7.5 mg x ml(-1) with bupivacaine 5.0 mg x ml(-1) for subclavian perivascular brachial plexus block. ⋯ Thirty ml ropivacaine 7.5 mg x ml(-1) (225 mg) produced effective and well tolerated brachial plexus block of long duration by the subclavian perivascular route. In this study, the results were similar to those of 30 ml bupivacaine 5.0 mg x ml(-1).

Randomized Controlled Trial Comparative Study Clinical Trial
Non-alkalinized and alkalinized 2-chloroprocaine vs lidocaine for intravenous regional anesthesia during outpatient hand surgery.
Chloroprocaine should be an ideal agent for intravenous regional anesthesia (IVRA) because of its rapid onset and ester hydrolysis. Raising the pH of local anesthetics may increase the speed of onset and the intensity of nerve blocks. We compared plain and alkalinized 2-chloroprocaine 0.5% with lidocaine for IVRA. ⋯ In conclusion, alkalinized chloroprocaine was found to be an effective agent for IVRA but no benefit over lidocaine was detected. Plain chloroprocaine for IVRA produced more minor side effects than lidocaine.
