Brachial plexus block (axillary approach) has been compared with ulnar nerve block for the evaluation of local anaesthetic drugs. Duration of analgesia is the same in both techniques with the same drugs. Following axillary nerve block the median, ulnar and radial nerves are blocked for a different time. ⋯ Larger amounts of local anaesthetic solutions are necessary for plexus blockade and this may cause toxic effects. The volunteer's comfort is less after plexus block because of more widespread paralysis. Therefore, ulnar nerve block and extradural block are in many respects the most suitable techniques for evaluation of new local anaesthetic agents.

Comparative Study Clinical TrialEtidocaine in intercostal nerve block for pain relief after thoracotomy; a comparison with bupivacaine.
For pain relief after thoracotomy, intercostal nerve block with etidocaine 1% and bupivacaine 0.5%, both containing adrenaline 5 mug/ml, was used. Duration of skin analgesia for sharp pain was around 11 hours for both solutions. Post-operative pain was noted 6 and 5 hours after injection for etidocaine and bupivacaine respectively. ⋯ Arterial and venous blood levels of the local anaesthetics were low and no signs of toxicity were noted. All patients experienced a certain pain relief from the blocks. Because of shoulder pain in some patients intercostal nerve block alone does not seem to be a perfect post-operative method for pain relief after thoracotomies.

Comparative Study Clinical TrialSupraclavicular brachial plexus block with etidocaine without vasoconstrictor. Preliminary report.
When used for supraclavicular brachial plexus blocks, etidocaine 1% gave a quick and sufficient onset. Its duration was longer than that of mepivacaine 2%, and equal to that of bupivacaine 0.5%. ⋯ The long-acting agents showed great variations in duration, and they all had longer regression times than mepivacaine. No serious pharmacological side-effects were observed during this study, and so far there are no reports on neurological sequelae.

Comparative Study Clinical TrialIntercostal blocks with etidocaine. Preliminary report.
Although the results are few and should be considered as preliminary, the following conclusions may be drawn: 1. Etidocaine 0.5% and bupivacaine 0.5%, both with adrenaline (5 mug/ml), are comparable with regard to duration of sensory block. 2. ⋯ Adrenaline added to the solution counteracts the dilating effect. 4. Blood level studies of etidocaine do not at present show differences when 0.5% solution with or without adrenaline is used.
