Patients with neonatal urea cycle defects (UCDs) typically have high mortality and poor neurological outcome unless they receive liver transplantation. Neurologic outcome may be better with liver transplantation before age one year. We report on a follow up on an initial prospective study performed to assess developmental outcome after early liver(More)
STUDY OBJECTIVE To quantify global coagulation and establish normal ranges for the celite-activated thrombelastograph (TEG) in healthy pediatric patients. DESIGN Prospective observational study. SETTING Operating suite of a university-based hospital. PATIENTS 110 healthy pediatric patients in four age groups and 25 healthy adult patients. (More)
PURPOSE To investigate perioperative coagulation in morbidly obese (MO) patients with the thromboelastograph (TEG) and Sonoclot analyzer. METHODS Twenty-six consecutive morbidly obese and 26 consecutive lean patients presenting for elective surgery were enrolled in this prospective, observational study. Blood was sampled for TEG and Sonoclot analysis(More)
UNLABELLED Although use of the Sonoclot device (Sienco, Inc., Morrison, CO) has been reported in isolated pediatric cases and in small reports in neonates, there are no published data for normal pediatric patients. As the device is used in situations of abnormal coagulation, such as cardiac and liver transplantation surgery, our aim was to determine normal(More)
Fifteen light for dates infants and their placentae were compared to 15 well-grown infants and their placentae. The former were born to thin, underweight women while the latter were born to women of normal weight. The light for dates infants were symmetrically growth retarded but not wasted at delivery and their placentae had a reduced weight, volume,(More)
