Brain magnetic resonance imaging using a customized vacuum shape-keeping immobilizer without sedation in preterm infants.

Objective: To validate that a customized vacuum shape-keeping immobilizer (VaSKI) can be used in preterm infants without sedation.

Methods: Preterm infants who underwent brain MRI from February 2008 to March 2017 at Osaka Medical College Hospital were retrospectively assigned to the sedation group (February 2008 to September 2013, n = 64) or VaSKI group (October 2013 to November 2016, n = 64). The examination success rates and diagnosable case classification were determined by pediatricians and radiologists.

Antenatal exposure to Ureaplasma species exacerbates bronchopulmonary dysplasia synergistically with subsequent prolonged mechanical ventilation in preterm infants.

Introduction: The presence of microorganisms in gastric fluid in neonates at birth is postulated to reflect antenatal infection and also to be associated with the development of bronchopulmonary dysplasia (BPD).

Results: A logistic regression analysis, after controlling for other risk factors, indicated that Ureaplasma-positive infants were not at increased risk for moderate/severe BPD (adjusted odds ratio (OR): 2.58, 95% confidence interval (CI): 0.
