Abstract
Background
Magnesium sulfate is an accepted intervention for fetal neuroprotection. There are some perceived differences in the international recommendations on the use magnesium sulfate for fetal neuroprotection in preterm labor.
Content
This systematic review analyses the available clinical guidelines for the use of magnesium sulfate for fetal neuroprotection and compares the recommendations, and assesses the quality of guidelines. This provides the consensus, differences and explores the areas for future collaborative research. We searched databases of PUBMED, EMBASE, COCHRANE, Web of Science, LILACS; and included the national and the international clinical practice guidelines. We included seven guidelines out of 227 search results. We evaluated the methodological quality of guidelines using the Appraisal of Guidelines Research and Evaluation (AGREE II) tool and systematically extracted guideline characters, recommendation and supporting evidence base.
Summary
Five guidelines were of high quality and two were of moderate quality. One guideline achieved more than an 80% score in all the domains of AGREE II tool. All guidelines recommend use of magnesium sulfate for fetal neuroprotection. However, there are differences in other recommendations such as upper gestational age, dose, duration, repeating treatment and use of additional tocolytics.
Outlook
Future guidelines should include recommendations on all aspects of magnesium sulfate therapy for fetal neuroprotection. Future research and international collaboration should focus on areas where there are no international consensual recommendations.
