CONTEXT: Prenatal magnesium sulfate may reduce the risk of cerebral palsy or death in very preterm infants. OBJECTIVE: To determine the effectiveness of magnesium sulfate given for neuroprotection to women at risk of preterm birth before 30 weeks' gestation in preventing pediatric mortality and cerebral palsy. DESIGN, SETTING, AND PATIENTS: Randomized controlled trial at 16 tertiary hospitals in Australia and New Zealand with stratification by center and multiple pregnancy. A total of 1062 women with fetuses younger than 30 weeks' gestation for whom birth was planned or expected within 24 hours were enrolled from February 1996 to September 2000 with follow-up of surviving children at a corrected age of 2 years. INTERVENTIONS: Women were randomly assigned to receive a loading infusion of 8 mL (4 g [16 mmol] of 0.5 g/mL of magnesium sulfate solution or isotonic sodium chloride solution [0.9%]) for 20 minutes followed by a maintenance infusion of 2 mL/h for up to 24 hours. MAIN OUTCOME MEASURES: Rates of total pediatric mortality, cerebral palsy, and the combined outcome of death or cerebral palsy at a corrected age of 2 years. RESULTS: Data were analyzed for 1047 (99%) 2-year survivors. Total pediatric mortality (13.8% vs 17.1%; relative risk [RR], 0.83; 95% confidence interval [CI], 0.64-1.09), cerebral palsy in survivors (6.8% vs 8.2%; RR, 0.83; 95% CI, 0.54-1.27), and combined death or cerebral palsy (19.8% vs 24.0%; RR, 0.83; 95% CI, 0.66-1.03) were less frequent for infants exposed to magnesium sulfate, but none of the differences were statistically significant. Substantial gross motor dysfunction (3.4% vs 6.6%; RR, 0.51; 95% CI, 0.29-0.91) and combined death or substantial gross motor dysfunction (17.0% vs 22.7%; RR, 0.75; 95% CI, 0.59-0.96) were significantly reduced in the magnesium group. CONCLUSIONS: Magnesium sulfate given to women immediately before very preterm birth may improve important pediatric outcomes. No serious harmful effects were seen.

Cerebral palsy is a condition that may be associated with swallowing disorders, that is, oropharingeal dysphagia. The aim of this study was to characterize and compare the swallowing processes of 32 children with this condition, by clinical and videofluoroscopic evaluation, with special focus on tracheal aspiration detectability. Results show an important compromise of oral phase. The most important findings during the pharyngeal phase were velopharingeal incompetence and residuals on the pharyngeal recesses. Aspiration was more common with liquids, before and after deglutition. On clinical and videofluoroscopic evaluation, cervical hyperextension was the commonest postural abnormality. Videofluoroscopy confirmed the occurrence of aspiration on most of the cases that presented suggestive signs of aspiration during clinical evaluation. We conclude that clinical and videofluoroscopic evaluations are complementary on deglutition evaluation and together may point to the most specific rehabilitation procedure.
