This study was performed to examine the effectiveness of color Doppler imaging (CDI) in demonstrating the neonatal intracranial vessels and altered intracranial flow patterns and to determine the optimal approach in imaging and intracranial vasculature. The study was conducted in two parts. First, 14 neonates were examined with CDI by using a standard(More)
The clinical use of extracorporeal membrane oxygenation (ECMO) in the treatment of persistent pulmonary hypertension following surgical repair of congenital diaphragmatic hernia is reported on 11 patients. The patients had a total of 13 treatments; two patients had two treatments. During the same period of clinical use, 122 patients were placed on ECMO for(More)
Attempts to predict the degree of pulmonary hypoplasia associated with congenital diaphragmatic hernia have been made by evaluating the ventilation parameters and the arterial blood gasses of these patients. A CO2 index as a predictor of outcome, which correlates the PaCO2 with the ventilation index, was recently proposed. However, in this study the(More)
A new, rapid technique for determining fetal lung maturity, the FELMA, was tested against the standard lecithin/sphingomyelin (L/S) ratio in predicting hyaline membrane disease (HMD). The FELMA was tested on 236 samples, 154 of which were compared with the L/S ratio; 102 neonates were delivered within 48 hours. There was a significant correlation between(More)
The development and implementation of neonatal intensive care services have been essential components of perinatal regionalization during the past two decades. The transport of critically ill infants to regional neonatal intensive care units has played an important role in improving neonatal outcome. This article presents a profile of Southern California's(More)
The intrinsic fluidity of lipid aggregates in amniotic fluid (AF) can be determined by FP, a spectral technique which monitors molecular motion. FP of lipids in AF has been found to correlate with other measures of lung maturity. In order to extend these observations and provide clinical correlation, FP was determined on amniotic fluid obtained during(More)
