[Epidural anesthesia in surgical interventions on the spine and spinal cord. I. Comparative analysis of the effectiveness of anesthesiological protection under conditions of epidural anesthesia and neuroleptanalgesia in surgery of the spine and and spinal cord].

The study was carried out in 22 patients operated on for vertebral disk hernias and spinal tumors at lumbosacral level. The patients were divided in 2 groups depending on the type of anesthesia (epidural or neuroleptanalgesia-EA and NLA). In the test group all patients were operated under EA with local anesthetics combined with intravenous sedative drugs (diprivan + relanium) under conditions of spontaneous respiration and O2 inhalation through a mask.

[The characteristics of epidural analgesia during the removal of lumbar intervertebral disk hernias].

Epidural analgesia (EA) was used in 29 patients undergoing surgical removal of lumbar discal hernia. Marcain EA with controlled medicinal sleep and non-assisted breathing allowed to perform the whole operation in 27 patients. EA may be ineffective in combination of sequestrated disk hernia with scarry adhesive process.

[Current and voltage kinetics of an autonomic electrostimulator of the gastrointestinal tract].

The paper presents experimental findings of the kinetics of current and voltage of a self-contained electric stimulator (SCES) of the gastrointestinal tract (GIT) with 12X18H9 stainless steel electrodes in 1% HCI solution (which mimics gastric juice). The structure and parameters of a dynamic SCES model are electrochemically considered. The model adequately describes experimental findings and may be used to generate capacity and Faraday components in the electrostimulation current at the electrode-electrolyte borders in order to evaluate the delivery of trace elements, which are deficient in the body, from the SCES electrodes into GIT on electrostimulation.

[Mechanism of glucose tolerance disorders in tumors located in the sellar-diencephalic area].

Clinical and biochemical examination carried out in 20 patients with tumors of the sellar-diencephalic area and 10 healthy persons revealed a dependence between functional disorders of the thalamus and hypophysis and the pancreatic beta-cells, which was attended by the development of obesity in patients with large endosuprasellar tumors of the hypophysis and diminution of glucose tolerance in all patients. Hyperinsulinemia revealed during intravenous glucose tolerance test and reduced glucose tolerance are evidence of relative insular insufficiency and substantiate pathogenetically the inclusion of insulin in the complex of intensive therapy applied in the early postoperative treatment of patients with tumors located in the sellar-diencephalic area.
