The plasma concentrations of bupivacaine and the latency and duration of anaesthesia after supraclavicular block with 30 ml of 0.5% bupivacaine were measured in 10 patients with chronic renal failure and in 10 patients with normal renal function. No significant difference was found between the two groups in respect of pharmacokinetic parameters, or in block latency or duration.

[Percutaneous echography-guided alcohol block of the celiac plexus as treatment of painful syndromes of the upper abdomen: study of 21 cases].
Celiac plexus block is usually performed under fluoroscopic or tomodensitometric guidance. We report on a new procedure using sonographic guidance. the patient lies in supine position. We use a real-time sonograph with a 3.5 MHz probe. ⋯ No treatment-related complication was observed. We conclude that sonography is a simple and safe method of guidance in performing alcohol block of the celiac plexus. The anterior approach may prevent neurologic complications occurring with other methods of guidance using a posterior approach.

Randomized Controlled Trial Comparative Study Clinical Trial
A comparison of lignocaine with prilocaine in axillary brachial plexus anaesthesia.
Twenty patients received either lignocaine 1.5% with 1/200,000 adrenaline (group L), or prilocaine 1.5% plain (group P) as a brachial plexus block for surgery to the upper limb, in a randomised double-blind study. The two groups were comparable in age, weight and duration of surgery and there were no significant differences between the two groups with regard to onset, pattern or degree of sensory loss. ⋯ All the blocks were performed using the same technique and provided complete surgical anaesthesia. Prilocaine 1.5% plain provides adequate sensory and motor blockade for brachial plexus anaesthesia and is a suitable agent for medium duration surgery to the upper limb.
