This single-injection, peribulbar technique provides a painless and efficacious block without the need for intravenous supplements. One hundred consecutive patients achieved lid akinesia and complete akinesia and anesthesia of the globe by the transconjunctival route. Only 1% needed a supplemental injection, and complications were minor and infrequent.

Case ReportsLong-term brachial plexus anesthesia using a subcutaneous implantable injection system. Case report.
Continuous brachial plexus anesthesia with local anesthesia has been used since 1946 for prolonged surgical procedures, in postoperative pain relief, and in sympathetic nerve block. The benefit or effectiveness of this technique in the relief of sympathetically maintained pain has yet to be established. ⋯ Controlled studies need to be done to establish the safety and efficacy of this form of therapy.

Randomized Controlled Trial Clinical Trial Controlled Clinical Trial
[Intubation conditions and circulatory effects 90 seconds after a divided mivacurium dose with three different TIVA induction methods].
The aim of this study was to compare the intubating conditions of a mivacurium-induced neuromuscular block 90 s after a divided administration with three different methods of induction of anaesthesia. ⋯ A dose of mivacurium 3.57 times the ED95 does not produce any haemodynamic instability, if it is divided into two parts to induce a TIVA. After this dose, all patients could be safely intubated within 90 s. A prolongation of the neuromuscular block after higher mivacurium doses could not be seen, and this dose did not produce a more rapid onset of the maximal block in any group. The time for recovery from a mivacurium infusion did not differ among the groups. Etomidate, due to its short half-life, seems not ideal for induction of a TIVA together with mivacurium in the dosage used. Mivacurium meets the demands of good controllability as required for a TIVA and can be recommended for a 90-s injection-intubation interval as well as for maintenance of the neuromuscular block.

Case ReportsVenous blood gas analysis for evaluation of blood circulation of the hand during continuous axillary block.
Computer analysis of blood gas measurements was used to evaluate the effect of a continuous axillary block on the circulation of the hand of a patient suffering from regional circulatory insufficiency due to ligation of the brachial artery. Venous blood samples drawn from the cephalic vein were analysed at 0, 1, 2.5 and 18 hours after the blockade. Improved circulation of the hand was indicated by decreased arterio-venous oxygen difference and increased venous oxygen partial pressure following the blockade. The advantage in using the extended blood gas analysis is the possibility of estimating the main factors influencing tissue oxygenation: oxygen capacity, oxygen partial pressure and the haemoglobin oxygen affinity.

Anaesthesia for microvascular surgery in children. A combination of general anaesthesia and axillary plexus block.
Nowadays, microvascular reconstructions are performed with high success rate even in small children. The combination of general anaesthesia and axillary plexus block was used in this prospective study in order to achieve optimal surgical conditions in these challenging operations. Fifteen children under eight years of age (1-8 years) were anaesthetised with a standardised anaesthesia method using a combination of general anaesthesia and axillary plexus block for microvascular toe-to-hand transfer. ⋯ One 1-year-old child developed a moderate hyperthermia of 39.1 degrees C. According to this study axillary plexus block can be combined with general anaesthesia in prolonged microvascular operations. When the effect of general anaesthesia ceased, the plexus block effectively increased peripheral circulation in the operated hand.
