Pilot Study of Magnesium Infusions in Pediatric Asthma

This study has been withdrawn prior to enrollment.

Keith Cross, University of Louisville Identifier:
First received: January 24, 2012
Last updated: March 29, 2017
Last verified: March 2017
This is a prospective randomized pilot study that seeks to address the research question: In children with moderate-to-severe asthma, do intravenous magnesium infusions added to standard Pediatric intensive care unit (PICU)-level asthma care significantly decrease time from patient presentation until PICU discharge?

Condition Intervention Phase
Drug: Magnesium Sulfate
Drug: Placebo
Phase 2
Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Participant, Care Provider, Outcomes Assessor
Primary Purpose: Treatment
Official Title: A Pilot Study of Magnesium Infusions (Drips) for Moderate-to-Severe Pediatric Asthma Exacerbations

Primary Outcome Measures:
  • Time to discharge [ Time Frame: Duration of hospital stay, typically 3-5 days ]
    The primary outcome for this study is elapsed time from emergency department (ED) presentation to readiness for PICU discharge.

Secondary Outcome Measures:
  • Beta receptor haplotype [ Time Frame: Once on enrollment ]
    The subject's genetic haplotype for beta adrenergic receptor. It will be determined by blood test during their admission in the hospital and enrollment on the study protocol.

Enrollment: 0
Study Start Date: January 2012
Study Completion Date: October 2013
Primary Completion Date: October 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Magnesium
Half the enrolled subjects will be randomized to receive active drug, a magnesium infusion.
Drug: Magnesium Sulfate
Continuous magnesium drip, titrated to effect until patient's symptoms improve
Placebo Comparator: Control
Half the subjects will be randomized to receive a drip that does not have active drug (magnesium sulfate).
Drug: Placebo
Simple saline drip, without active drug

Detailed Description:
This study will be a double-blind, prospective randomized pilot study. Subjects will be randomized on a 1:1 basis to receive routine asthma care with or without a magnesium drip.
