BACKGROUND We investigated the effects of a magnesium sulfate pretreatment on intubating conditions and cardiovascular responses during rapid sequence tracheal intubation (RSI) in this double-blind randomized study. METHODS Adult patients (n = 154) were randomly allocated to a rocuronium-0.6, rocuronium-0.9, or magnesium group. The magnesium group was pretreated with 50 mg/kg MgSO4, and the o...

The purpose of this study was to examine the effect of intravenous magnesium sulfate on patients with COPD exacerbation requiring hospitalization. In this randomized clinical trial 30 patients with COPD exacerbation were studied. Patients were randomly assigned to group A (case) who concurrent with standard therapy received 2g magnesium sulfate in normal saline infused in 20 minutes on days one...

Objective In terms of efficacy, several previous studies have shown that the success rate in inhibiting preterm labor was not different between magnesium sulfate and ritodrine. However, there is a paucity of information regarding the efficacy of both medications after consideration of intra-amniotic infection, which is one of the most important prognostic factors in patients of threatened prete...

Background: Several studies have shown that administration of magnesium sulfate prolongs the bleeding time. Objective: To investigate such effects in pregnant women in Shiraz, southern Iran.  Methods:This study was conducted on 30 pregnant women aged between 18 and 32 yrs, with a gestational age of 20 to 37 weeks, who presented to Hafez and Zeynabiyeh Emergency Units affiliated to Shiraz Univer...

Objective: Evidence shows that magnesium has anti-arrhythmic roles. However, clinical trials suggest that there are conflicting outcomes of cardiac arrest patients given magnesium. The study aimed to examine the effects of magnesium sulfate therapy on cardiac arrest patients using a meta-analysis. Methods: We searched the MEDLINE (1966-July 2011), OVID (1980-July 2011), EMBASE (1980-July 2011),...
