We report the case of a patient who had development of ventricular fibrillation following rapid intravenous administration of magnesium sulfate (2 g over 5 s) for treatment of sustained monomorphic ventricular tachycardia. Initial slowing of the tachycardia was followed by gradual widening of QRS complexes and electrical alternans, leading to ventricular fibrillation within 3 min of magnesium a...

BACKGROUND AND OBJECTIVES Hemodynamic response to airway stimuli is a common phenomenon and its management is important to reduce the systemic repercussions. The objective of this study is to compare the efficacy of intravenous magnesium sulfate versus lidocaine on this reflex hemodynamics after laryngoscopy and tracheal intubation. METHODS This single-center, prospective, double-blind, rando...

1. The electrolyte composition, the pH, and freezing points of the fluids of several invertebrates and one primitive chordate are reported. 2. Fluids of the worms, echinoderms, and the clam Venus were isotonic with sea water; fluids of the Arthropoda were hypertonic to sea water. 3. The pH of all fluids was below that of sea water. In the Arthropoda and Myxine less individual variation in pH ap...

BACKGROUND The aim of this study was to investigate the effect of magnesium administered before induction on the hemodynamic response and QT dispersion (QTd) related with intubation in hypertensive patients and to compare it with lidocaine. METHODS Patients with essential hypertension who were under ≤ 65 years old, scheduled for elective surgery with a Mallampati score of I-II were included i...

BACKGROUND Drugs currently available for the acute treatment of paroxysmal atrial fibrillation have significant limitations. We assessed the safety and effectiveness of intravenous magnesium sulfate versus diltiazem therapy in patients with prolonged episodes of paroxysmal atrial fibrillation. METHODS In a prospective randomized trial, 46 symptomatic patients presenting with paroxysmal atrial...

Introduction Magnesium is an N-methyl-D-aspartate receptor blocker and it’s known to have analgesic effect [1,2]. Hypomagnesaemia is often seen in major surgery and it is associated with higher morbidity, mortality, organ dysfunction, systemic inflammatory response syndrome and pulmonary hypertension [2,4]. It’s shown that intra-operative use of magnesium sulfate reduced per-operative analgesic...

The thermophilic Geobacillus bacterium catalyzed the formation of 100-μm hexagonal crystals at 60°C in a hydrogel containing sodium acetate, calcium chloride, and magnesium sulfate. Under fluorescence microscopy, crystals fluoresced upon excitation at 365 ± 5, 480 ± 20, or 545 ± 15 nm. X-ray diffraction indicated that the crystals were magnesium-calcite in calcite-type calcium carbonate.

MgSO4 is routinely used in therapeutics despite its toxicity. The aim of the present review was to compare MgSO4 and MgCl2 effects in order to answer the question whether MgSO4 could be or not replaced by MgCl2. Considering that the two salts have both similar and proper effects, a clear-cut conclusion is not easy to draw. However, choosing MgCl2 seems advisable because of its more interesting ...
