BACKGROUND The current study was designed to test the hypothesis that the increased duration of analgesia caused by adding dexmedetomidine to local anesthetic results from blockade of the hyperpolarization-activated cation (I(h)) current. METHODS In this randomized, blinded, controlled study, the analgesic effects of peripheral nerve blocks using 0.5%… (More)
BACKGROUND The current study was designed to test the hypothesis that dexmedetomidine added to ropivacaine would increase the duration of antinociception to a thermal stimulus in a dose-dependent fashion in a rat model of sciatic nerve blockade. METHODS Fifty adult Sprague-Dawley rats (10 rats/group) received unilateral sciatic nerve blocks with 0.2 ml… (More)
BACKGROUND AND OBJECTIVES The present study was designed to test the hypothesis that perineural dexmedetomidine provides a longer duration of analgesia than the same dose given subcutaneously in a peripheral nerve block in rats. METHODS Fifty-four rats received unilateral sciatic nerve blocks along with a subcutaneous injection at the base of the neck by… (More)
The author, after a short introduction about the pathogenesis of pregnant lumbago and the following alteration of the lumbo-pelvic rhythm, test his patients considering the value of the lumbar's segment mobility in conformity with the Schoberth's test modified by Troisier. After, he explains his manipulations techniques and his results.
