The evolution of central segmental blockades was studied in 133 patients by using epidural and spinal anesthesias. The efficiencies of 2% Ultracaine (Hoechst) and 2% Lidocaine (Egis) solutions used for epidural anesthesia and 5% Ultracaine (Hoechst) and 0.75% Bupivacaine (Astra) hyperbaric solutions were evaluated. Central segmental blockade induced by Ultracaine was found to be similar to Lidocaine and Bupivacaine in clinical parameters. ⋯ No differences were found in the magnitude of hemodynamic changes both with various anesthetics and different types of segmental blockades. The findings make it possible to regard Ultracaine as an drug that has some advantage over Lidocaine for prolonged epidural anesthesia and similar to the latter in pharmacological characteristics. Ultracaine may be regarded as alternative to Bupivacaine for spinal anesthesia.

Randomized Controlled Trial Comparative Study Clinical Trial[Prevention of arterial hypotension during spinal anesthesia using intramuscular ephedrine in older people].
To assess the efficacy of intramuscular ephedrine for prevention of hypotension following subarachnoid block (SB) in the elderly. ⋯ Prophylactic intramuscular ephedrine is effective to prevent hypotension associated with SB in the elderly.

Randomized Controlled Trial Comparative Study Clinical Trial[Effects of CO2 and adrenaline on 1% lidocaine in axillary block].
To compare lidocaine hydrocarbonate and lidocaine hydrochloride, with and without adrenaline, in the axillary block obtained with a neurostimulator. ⋯ Considering the cost/benefit ratio and the absence of clinical benefits of lidocaine hydrocarbonate, lidocaine hydrochloride should be preferred.

Randomized Controlled Trial Clinical Trial[Brachial plexus block: effect of the addition of sufentanil to local anesthetic mixture on postoperative analgesia duration].
To compare the quality and the duration of analgesia produced by a supraclavicular brachial plexus blockade obtained with a mixture of lidocaine and bupivacaine when supplemented or not with sufentanil. ⋯ Sufentanil added to a mixture of lidocaine and bupivacaine increases twofold the duration of postoperative analgesia following branchial plexus blockade.

Comparative StudyGeneral anaesthesia versus cervical block and perioperative complications in carotid artery surgery.
To compare the influence of anaesthetic technique on perioperative complications in patients undergoing carotid endarterectomy. ⋯ Cervical block anaesthesia yields better perioperative results than general anaesthesia probably because it allows more reliable cerebral monitoring, reducing or even eliminating perioperative strokes related to clamping ischaemia. It facilitates detection of the mechanism underlying intraoperative stroke allowing surgical techniques and intraoperative management to be modified accordingly. Cervical block anaesthesia significantly reduces the need for internal carotid artery shunting.
