    The information system for analyzing the symptoms of a patient's disease, determining a preliminary diagnosis, and providing recommendations for contacting a doctor of a certain specialization is developed. The curent recommendation system performs the following main functions: preliminary medical diagnosis according to the selected symptoms; formation of reminder about taking medications; formation of history of taking medication.

    Plexus brachialis strain and compression deformation in the costo-axillary-brachial region : A cadaveric study
    (2011) Vasilevskis, Edgars; Skuja, Sandra; Evansa, Irina; Šteina, Eva; Pilipa, Anna Sondore; Vabels, Grigorijs; Teibe, Uldis; Jansons, Haralds; Groma, Valerija; Vanags, Indulis; Rīga Stradiņš University; Department of Morphology; Department of Anaesthesiology, Intensive Care and Clinical simulations
    Objective: The aim of this study was to clarify the role of different mechanisms in nerve injury during arm abduction positions. The tasks were to determine the strain deformation of the plexus brachialis during arm abduction, to measure the pressures in the neurovascular bundle in the cervico-costoclavicular-axillary area, and evaluate the histological changes of nerve after the stretch test. Material and Methods: During the cadaveric study on 7 specimens 7-20 h after death, strain deformation of plexus brachialis as well as compression deformation caused by the surrounding structures of the neurovascular bundle were investigated in the arm abduction position of 0°, 90°, 12°, 150°, and 180°. One nerve sample was studied histologically after 15% stretch on the bench. Results: The relative strain deformation of 3%-23% was documented during 0° to 180° abduction tests. The strain deformation from 0° to 90° was significant (P<0.001). The mean pressure change in the bundle was 13.6 mm Hg at 90°, 53.7 mm Hg at 120°, 73.4 mm Hg at 150°, and 89.0 mm Hg at 180° arm abduction. An increase in pressure was significant in the intervals: 0°-90° (P<0.001), 91°-120° (P<0.001), 121°-150° (P<0.001) and 151°-180° (P<0.05). Conclusions: Nerve traction and tissue compression arising during the arm abduction above 90° were found to be sufficient to induce lesions in neural bundles of the plexus brachialis.

    Special Devices for Regional Anaesthesia
    (2008-01) Vasilevskis, Edgars; Miščuks, Aleksejs; Vanags, Indulis; Rīga Stradiņš University
    The rapid growth of regional anaesthesia in the last 20 years has resulted in an increasing number of technical devices. Technical resources play a very considerable role in modern regional anaesthesia and they are being introduced to facilitate the quality performance of this type of anaesthesia. The task of this survey is to summarise the most important technical devices currently utilised for regional anaesthesia and to provide a review of the history of their introduction. Technical devices for performing regional anaesthesia could be divided in seven groups: 1) neurostimulation and simple needles and catheters; 2) neurostimulator with transcutaneous nerve stimulation (TENS); 3) ultrasonograph with a device to fix the probe; 4) devices for injection of local anaesthetics, such as perfusors, patient controlled analgesia systems and elastomeric infusion systems; 5) arm, leg and instruments supports; 6) regional anaesthesia injection monitor and data register devices, and 7) catheter fastenings and auxiliary materials. It is recommended that all of the apparatus applied should be classified to make it easier to acquire more immediate and understanding, and be easy to add this knowledge to the overall checklist before starting anaesthesia. The history of the introduction of technical equipment shows how much time was necessary for the development of modern regional anaesthesia methods.
