An interventional study of ้High-dose Magnesium sulphate and standard-dose Magnesium Sulfate in Asthma Exacerbation, Emergency Department and Magnesuim Sulfate, sponsored by Thammasat University. Not yet recruiting. Open to participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-08-31.
Sponsored by Thammasat University · Not applicable, Interventional, and Treatment
The goal of this clinical is to compare treatment outcomes between high dose continuous IV Magnesium and standard therapy in the management of acute exacerbation of asthma in the emergency department. Participants will random assign to either high dose continuous IV drip or standard infusion. Participants in the intervention group received high-dose 50% magnesium sulfate (MgSO4), consisting of 2 g + normal saline (NSS) 100 ml administered intravenously over 30 minutes, followed by MgSO4 6 g + NSS 350 ml infused over 3.5 hours (approximately 40-50 mg/kg/h). In contrast, participants in the control group received standard-dose 50% MgSO4, consisting of 2 g + NSS 100 ml administered intravenously over 30 minutes, followed by a NSS 350 ml infusion over 3.5 hours. Measurements include symptom severity, respiratory rate, oxygen saturation, and pulmonary function tests. Primary endpoints are ED stay length, hospital admission, and ED revisit within 48 hours post-discharge. Adverse events are documented.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.
GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².
Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.

Participants in the intervention group received high-dose 50% magnesium sulfate (MgSO₄), consisting of 2 g diluted in 100 mL normal saline (NSS) administered intravenously over 30 minutes, followed by MgSO₄ 6 g diluted with NSS up to a total volume of 350 mL infused intravenously over 3.5 hours (approximately 40-50 mg/kg/h).

Length of ED stay (hours)
Length of ED stay was defined as the time from administration of the first nebulized treatment to the time of physician-ordered disposition from the emergency department.
Time frame: through study completion, an average of 1 year
Hospital admission rate (%)
Hospital admission rate (%) was defined as admission to an inpatient ward or intensive care unit directly from emergency department following the index visit.
Time frame: through study completion, an average of 1 year
