BACKGROUND In the present study, we used Doppler velocimetry in the ophthalmic artery to evaluate the hemodynamic status of the intracranial vasculature. This is the first time in the literature that indices of ophthalmic artery Doppler sonography of women with preeclampsia were evaluated before and after the use of magnesium sulfate to prevent eclampsia. CASE PRESENTATION Indices of ophthalm...

Introduction In the United States, parenteral magnesium sulfate has been used for the prevention of recurrent seizures in patients with eclampsia for over 80 years. As a natural extension to its use for the treatment of eclamptic convulsions in the United States, magnesium sulfate was then adopted for seizure prophylaxis in women with varying degrees of hypertensive disorders of pregnancy. In 1...

Because ketamine and magnesium block NMDA receptor activation by distinct mechanisms of action, we hypothesized that in a model of inflammatory pain in rats the combination of ketamine and magnesium might be more effective than ketamine alone. Antinociceptive activity was assessed by the formalin test in male Wistar rats (200-250 g). Animals were injected with 100 μL of 2.5% formalin to the pla...

BACKGROUND Studies of IV magnesium sulfate as a treatment for acute asthma have had mixed results, with some data suggesting a benefit for acute severe asthma, but not for mild-to-moderate asthma. In a multicenter cohort, this study tests the hypothesis that administration of magnesium sulfate improves pulmonary function in patients with acute severe asthma. DESIGN Placebo-controlled, double-...

In this paper, the corrosion residual strength of the AZ91D magnesium alloy in the presence of sulfate-reducing bacteria is studied. In the experiments, the chemical composition of corrosion film was analyzed by a scanning electron microscope with energy dispersive X-ray spectroscopy. In addition, a series of instruments, such as scanning electronic microscope, pH-meter and an AG-10TA materials...

Objectives. We tested the hypothesis that administration of magnesium sulfate in labor protects against the development of neonatal brain lesions and cerebral palsy (CP) in low birth weight infants. Methods. Magnesium exposure was ascertained in a population-based cohort of 1105 infants weighing 2000 g or less through review of medical records of maternal magnesium sulfate administration and, w...

We induced experimental delayed cerebral vasospasm by the intracisternal injection of greater than 0.5 ml blood in 30 rats. Seventy-two hours later the basilar artery was exposed via the transclival approach and photographed at high-power magnification through an operating microscope. We then evaluated the effect of topical (n = 30) and intravenous (n = 20) magnesium sulfate on the spastic arte...

BACKGROUND Spinal anesthesia is widely used for caesarean section. Addition of intrathecal magnesium sulfate to local anesthetics seems to improve the quality of block and prolong the duration of analgesia. OBJECTIVES The present study was designed to examine whether addition of intrathecal magnesium sulfate enhances the analgesic efficacy of intrathecal bupivacaine in patients undergoing ces...

Background: Cisplatin is an antineoplastic agent used to treat many malignancies; however, the main side effect of cisplatin is nephrotoxicity. The aim of this study was to evaluate the effect of hydration therapy with and without magnesium on prevention of cisplatin-induced nephrotoxicity. Methods: This retrospective study was performed on 46 patients with malignancy who were candidate to rec...
