Item type:Publication, Does the addition of dexamethason to local anesthetic prolong the analgesia of interscalen plexus brachialis block in patients with shoulder surgery?(Association of medical doctors Sanamed Novi Pazar, 2016); ; ; ; Introduction: Peripherial nerve blocks is a suitable alternative to general anesthesia especially for one-day case surgery. Interscalene approach of plexus brachialis block as much as supraclavicular and infraclavicular provide reliable, safe, effective, low cost andmostcompleteanesthesia withsatisfactory postoperative analgesia for upper limb surgery. Postoperative analgesia of plexus brachialis blocks can be prolonged by using different drugs as adjuvants with local anesthetics. Dexamethasone has been shown to prolong the duration of postoperative analgesia when given as an adjunct for peripheral nerve blocks. The investigation was randomized, prospective, double blinded and controlled study. Objective: The study was designed to compare the effects of dexamethasone administered as an adjunct to bupivacaine in interscalene brachial plexus block on the onset, duration and postoperative analgesia in patients under the shoulder surgery. Methods: A prospective, double-blind study was undertaken in patients scheduled for shoulder surgeries under the interscalene brachial plexus block. We enrolled 60 patients, ASAI-II both sexes, aged 19-65 years, weighing 54-89 kg, divided to two groups G1 and G2. The brachial plexus block was performed by interscalene approach andmixtureof2%lidocaine(12ml)and0.5%bupivacaine (22 ml) either alone or combined with dexamethasone (4 mg). The block was performed by using double technique neurostimulator/ultrasound technique. Results: In our investigation we found a significant increase in onset and duration of motor and sensory block in Group G2(with dexamethasone) as compared to Group G1 patients (p < 0.01). Conclusion: Addition of dexamethasone to local anesthetic drugs in interscalene plexus brachialis block, significantly prolongs the duration of analgesia and motor block in patients undergoing shoulder arthroscopy. Moreover, it is a remarkably safe and cost effective method of providing postoperative analgesia. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Stereological study of the Wistar rats` thymus after application of high therapeutic doses of dexamethasone and medroxyprogesterone acetate(Macedonian Association of Anatomists and Morphologists, 2017); Aim: The aim of our study was to evaluate the eventual immunosuppressive effect of high therapeutic dose of medroxyprogesterone acetate (MPA), to determine morphological and stereological thymic tissue characteristics and to compare them with the morphological characteristics induced by the high therapeutic dexamethasone (Dex) dose. Material and Methods: A total of 36 female Wistar rats were divided into three groups. The control group of rats were administered physiological solution, whereas the experimental groups received Dex at a dose of 3 mg/kg bw and MPA at a dose of 150 mg/kg bw. Drugs were administered intramuscularly every day, in a period of 7 days. Thymus paraffin sections were stained according to the following methods: hematoxylin-eosin, periodic acid-Schiff and elastica-van Gieson. The stereological measurements were performed by using the Weibel’s multipurpose test system (M-42). Results: Histological analysis in the drug-treated rats showed disrupted thymic cytoarchitecture, lymphocyte density reduction which in some areas was to a degree of lymphocyte depletion, presence of Hassal’s corpuscles in thymic lobules medulla and abundant presence of interstitial connective tissue. Stereological analysis showed a significant reduction in the thymic parenchyma volume density, which was due to the more pronounced decrease in the thymic lobules cortex volume density and a significant increase of the interstitial connective tissue volume density. Conclusion: Our results showed that the high therapeutic dose of MPA provoked a marked reduction in immunocompetent lymphoid tissue, which led in changing the proportion of thymic structural components. These resulted in an immunosuppressive effect. Almost identical changes were caused by the high therapeutic dose of Dex, but thymic parenchyma was significantly more sensitive substrate for Dex than for MPA. - Some of the metrics are blocked by yourconsent settings
