About 5% of normal subjects fail to produce increased hydrogen breath concentration after ingestion of the non-digestible carbohydrate lactulose (low hydrogen producers). The existence of low hydrogen producers limits the diagnostic use of hydrogen (H2) breath tests. We studied the effects of lactulose and of magnesium sulphate (MgSO4) pretreatment on stool-pH and on hydrogen exhalation after o...

UNLABELLED The aim of this work was to evaluate the effect of magnesium sulphate (MgSO4) administration on blood-brain barrier (BBB) permeabilization after cerebral hypoxia-ischemia (HI) induced by partial occlusion of the umbilical cord of premature fetal lambs. We also characterized BBB dysfunction in terms of the levels of expression of a panel of BBB proteins; Occludin, Claudin, Zona Occlud...

BACKGROUND AND OBJECTIVE Vaso-occlusive episodes (VOEs) are the most common complication of sickle cell disease in children. Treatment with magnesium seems to improve cellular hydration and may result in reduced vaso-occlusion. This study aimed to determine if intravenous (IV) magnesium sulfate (MgSO4) reduces length of stay (LOS) in hospital, pain scores, and cumulative analgesia when compared...

BACKGROUND In patients with subarachnoid hemorrhage (SAH), vasospasm remains one of the major complications. The application of intravenous magnesium sulfate (MgSO4) has been under discussion to prevent cerebral ischemia. Our aim was to examine the impact of early MgSO4 administration on local cerebral microcirculation during microsurgical clipping of SAH-related aneurysms. METHODS The non-in...

tudy Objective: To study the role of magnesium sulphate (MgSO4) on analgesic equirement, pain, discomfort, and sleep during perioperative period. esign: prospective, double-blinded, randomized study. ettings: Operating room and recovery ward at a university teaching hospital. atients: 50 ASA physical status I and II patients scheduled for elective open cholecysectomy with general anesthesia. nt...

Extracellular glutamate is elevated following brain ischemia or trauma and contributes to neuronal injury. We tested the hypothesis that magnesium sulfate (MgSO4, 3 mM) protects against metabolic failure caused by excitotoxic glutamate exposure. Rat cortical neuron preparations treated in medium already containing a physiological concentration of Mg(2+) (1 mM) could be segregated based on their...

BACKGROUND Remifentanil induced hyperalgesia (RIH) is characterized by stimulation evoked pain including allodynia and thermal hyperalgesia after remifentanil infusion. N-methyl-D-aspartate (NMDA) receptor was reported to be involved in the progress of RIH. We hypothesized that intrathecal MgSO4 could relieve hyperalgesia after remifentanil infusion via regulating phosphorylation of NMDA recept...

BACKGROUND Magnesium sulphate (MgSO4), NMDA receptor antagonist, is known to reduce perioperative requirement of anesthetics and analgesics. However, no studies assessed the effect of MgSO4 on onset and recovery from spinal anesthesia. A prospective, randomised, double blind study was designed to assess the effect of intravenous (IV) MgSO4 on onset and recovery from spinal anesthesia and post o...
