Case Reports
[High spinal anaesthesia following intrathoracic intercostal nerve block. Report of a case (author's transl)].
In a 59-year-old female, anaesthetized with halothane, nitrous oxide/oxygen, intercostal nerve blocks were performed after right lateral thoracotomy. Before closure of the chest four segments were blocked each with 3 ml 0.5% bupivacain (Marcain, Carbostesin) without adrenaline. ⋯ The patient was able to be extubated 90' after the last block and there were no further complications. The possible mechanism of producing spinal anaesthesia after peripheral nerve blocks and the necessary precautions to avoid this complication are discussed.

Sciatic block with Mepivacaine (3-4 mg/kg) revealed successful in 91.9% of 340 rheumatoid patients with Keller/Clayton operation. In unsufficient blocks (8.1%) supplementary anesthesia by femoral nerve block, reblocking the sciatic nerve or local anesthetics secondarily gave good operating conditions. In three cases it was necessary to use additional spinal anesthesia. The concomitant sympathetic block gives an immediate cessation of sweating and a long lasting evaluation of skin temperature.

Catheter technique in axillary plexus block. Presentation of a new method.
A flexible, disposable intravenous catheter can be introduced into the neuro-vascular sheath in the axilla and used for injection of local anesthetic solution to block the axillary brachial plexus. The technique is described and the results of the first 137 consecutive catheter blocks are reported and compared to a similarly evaluated series of conventional axillary blocks. The catheter method constitutes an interesting alternative to needle techniques and offers the possibility of a continuous axillary block.

Peripheral nerve injury due to injection needles used for regional anesthesia. An experimental study of the acute effects of needle point trauma.
Nerve injury can arise as a complication peripheral nerve block anesthesia. Of the various factors involved, the trauma caused by the injection needle may be of significance. ⋯ Fascicular injury was indicated by a fluorescence microscopy technique, tracing locally applied Evans Blue Albumin, The results show that a 45 degrees-beveled needle less frequently produces fascicular damage and should therefore be recommended for use in clinical anesthesia. It is also concluded that paresthesiae, when necessary, should be elicited gently, and that intraneural injections should be avoided.
