Abstract

Magnesium sulfate displays numerous characteristics that make it a useful drug in anesthesiology (N-methyl-d-aspartate receptor antagonist, vasodilator, antiarrhythmic, inhibitor of catecholamine release and of acetylcholine in the terminal motor plate). The perioperative use of this drug as an adjuvant capable of decreasing the required dose of anesthetics, has been proposed. To assess the influence of intravenous magnesium sulfate administration during general anesthesia on the overall dose of required anesthetics. A systematic review of controlled randomized trials and meta-analysis. An electronic bibliography search in MEDLINE and in the Cochrane Database of Controlled trials (CENTRAL) up to 2015. Randomized, double-blind trials relating to general anesthesia in elective surgery using intravenous magnesium sulfate that provide information about the anesthetic requirements in ASA I and II patients. 20 clinical trials were selected for the qualitative analysis and 19 for the quantitative one. The use of perioperative intravenous magnesium sulfate reduces the requirement of the anesthetic, propofol during induction (-28.52mg; CI 95% -35.22-1.82; p<0.001) and maintenance (-213.56mg; CI 95% -322.93, -104.18; p<0.001) of anesthes...Continue Reading

Anti-Arrhythmic Drug Therapies

Anti-arrhythmic drugs are used to prevent abnormal heart rhythms. These medications are used in conditions including, ventricular tachycardia, ventricular fibrillation and atrial fibrillation. Discover the latest research on anti-arrhythmic drug therapies here.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Antiarrhythmic Agents: Mechanisms of Action

Understanding the mechanism of action of antiarrhythmic agents is essential in developing new medications as treatment of cardiac arrhythmias is currently limited by the reduced availability of safe and effective drugs. Discover the latest research on Antiarrhythmic Agents: Mechanism of Action here.
