[High conduction block of the brachial plexus using axillary approach].

An original technique of the brachial plexus block from the axillary approach is presented. The recommended technique suggests introduction of a rigid catheter into the paraneural space of the plexus up to the level of the sternoclavicular triangle. This provides for a high efficacy of the anesthesia and prevents development of complications. The methodology was elaborated on the basis of anatomic (n = 20) and clinicoradiological (n = 29) studies. The clinical evidence was obtained from 115 anesthesias for long-term reconstructive and plastic operations on the upper limb. A protocol for conduction anesthesia maintenance by repeated administration of lidocaine, trimecaine, and bupivacaine solutions is offered.

[The inguinal paravascular technique of lumbar plexus block--anatomical pretests were unsuccessful].

Using 28 anatomic preparations, the boundaries of dye expansion in tissues adjacent to nervous stems have been experimentally studied during the application of lumbar plexus local anesthesia technique via inguinal paravascular approach according to A. Winnie. It has been established that the above technique is not associated with anatomic conditions for simultaneous contact of a model dye solution with 3 basic derivates of the lumbar plexus both at the level of formation and further on. There is massive dye diffusion from femoral nerve perineural space into the intermuscular connective tissues. Compact structure of perineural spaces in musculus psoas major prevents lumbar plexus infiltration. The junction of lumbar and obturator fascia, forming the fascial node between large and small pelvis, excludes any possible contacts between the dye solution and the obturator nerve.

[Infusion therapy tactics during prolonged reconstructive and plastic surgery using microsurgical techniques].

The impact of various infusion therapy techniques has been studied in 166 patients during microsurgery for posttraumatic tissue defects. It has been established that the achievement of hypervolemic hemodilution is accompanied by the damage of water-electrolyte homeostasis and peripheral circulation during the operation and on the first postoperative day. Normovolemic hemodilution makes it possible to prevent the above disturbances and optimize peripheral blood flow in case the infusion programme is compiled adequately with an obligatory introduction of blood plasma preparations.

[A comparative analysis of the efficacy of trimecaine, lidocaine and bupivacaine for a prolonged brachial plexus block].

Local anesthetic effects of trimecaine, lidocaine and bupivacaine have been compared in high axillary brachial plexus blockade in 110 patients operated on the lower limb. The clinical pattern of conductive anesthesia and its efficacy (90 to 95.5%) did not depend on the kind of the anesthetic used. The rate of analgesia development in this technique is determined by physicochemical properties of the drug. Trimecaine effect is of minimum duration (130.0 +/- 1.3 min), while bupivacaine effect is of maximum duration (375.7 +/- 22.7 min). Lidocaine has an intermediate position (161.4 +/- 2.6 min).
