<![CDATA[AbstractIndonesia is the country with the fifth highest figure in the world of prematurity. The incidence of severe preeclampsia in Indonesia as much as 31.04%.Indonesia still use magnesium sulfate as an anti-seizure medications and recurrent seizures. Some developed countries in the world have been using magnesium sulfate as a neuroprotective fetus during antenatal for baby with a risk of premature birth. Premature babies have an increased risk of morbidity short term and long term. Nearly 50% of premature babies have neurological problems such as motor disorders. This study aimed to determine the effect of a history of the use of magnesium sulfate in the mother during antenatal against gross motor development in children aged 2-3 years. Analytic observational research with cross-sectional approach. Samples were selected by using purposive sampling with 30 respondents. Collecting data on the data preterm infants with a history of giving antenatal magnesium sulfate obtained through medical record RSIA Puri Bunda Malang and gross motor development is obtained by means of door-to-door using a checklist denver II. Analysis of the results of studies using the Fisher Exact Test correlation test. The research data is obtained as much as 43.3% of respondents with a history of antenatal magnesium sulphate diagnosed normal gross motor development, 6.7% suspect and no diagnosed untestable. While the respondents without a history of antenatal magnesium sulphate showed 16.7% of children diagnosed normal gross motor development and 33.3% suspect and no respondents who were diagnosed untestable. The results showed that there was a significant effect (p value = 0.008), so that it can be concluded that a history of antenatal magnesium sulfate use in premature babies have a better effect than the group that did not have a history of use of antenatal magnesiumsulfate.]]>
