Intravenous Bag Label The safety profile of intravenous MgSO4 also appears to be distinctly superior compared with the other agents. The pH of a 5% solution is between 5.5 and 7.0. A 2014 Cochrane review of 14 RCTs found a 25% reduction in hospital admissions in adults who were treated in the emergency department with intravenous magnesium sulfate for asthma exacerbation (N = 1,769; OR = 0.75; 95% CI, 0.60 to 0.92).2 The number needed to treat to prevent one admission was 7 (95% CI, 2 to 13). Cardiac conduction is altered at greater than 7.5 mmol/L, and cardiac arrest can be expected when concentrations of magnesium exceed 12.5 mmol/L.

Pouch Label Excretion: Magnesium is excreted solely by the kidney at a rate proportional to the serum concentration and glomerular filtration. Emesis is a common side-effect, while a reduction in seizure threshold is reported even with therapeutic serum levels [33]. Until an adequately powered head-to-head trial shows superiority of any of the other intravenous bronchodilators, MgSO4 is the obvious choice. TIME/ACTION PROFILE (anticonvulsant effect), CV: arrhythmias, bradycardia, hypotension. A previous smaller trial [31] compared intravenous MgSO4 and salbutamol in a critical care environment. A recent Paediatric Emergency Care Applied Research Network (PECARN) registry review noted the use of intravenous MgSO4 is in around 10% of children presenting with acute asthma, with the median time from triage to administration around 2.5h.
