The effects of delivery route and anesthesia type on early postnatal weight loss in newborns: the role of vasoactive hormones.

Objective: To investigate the effects of delivery route and maternal anesthesia type and the roles of vasoactive hormones on early postnatal weight loss in term newborns.

Methods: Ninety-four term infants delivered vaginally (group 1, n=31), cesarean section (C/S) with general anesthesia (GA) (group 2, n=29), and C/S with epidural anesthesia (EA) (group 3, n=34) were included in this study. All infants were weighed at birth and on the second day of life and intravenous (IV) fluid infused to the mothers for the last 6 h prior to delivery was recorded.

A chromosomal-effect study of intensive phototherapy versus conventional phototherapy in newborns with jaundice.

In this study, we aimed to make a comparison between chromosomal effects caused by conventional phototherapy and intensive phototherapy in jaundiced newborns. The study group included 83 newborns with gestation age of > or =35 weeks, and on days 3-10 after birth. Newborns were divided into four groups on the basis of total serum bilirubin (TSB) levels upon admission and need for phototherapy.

Maternal and umbilical venous adrenomedullin and nitric oxide levels in intrauterine growth restriction.

Objective: To verify whether adrenomedullin (AM) and nitric oxide (NO) concentrations are changed in the maternal and fetal circulation in pregnancies complicated by intrauterine growth restriction (IUGR) compared to normal pregnancies, and to determine any relationship between them.

Methods: Forty-six small for gestational age (SGA) and 34 appropriate for gestational age (AGA) infants were included in the study. Umbilical and maternal venous AM and NO concentrations were determined.

Hypernatremic dehydration in the newborn period and long-term follow up.

Background: Hypernatremic dehydration due to inadequate fluid intake can be a significant problem during the neonatal period and thereafter. The objective of the present study was to evaluate the term newborn infants admitted to Gazi University Hospital neonatal intensive care unit (NICU) for hypernatremic dehydration between June 2001 and June 2003 and compare the results with those of the literature search performed via MEDLINE for infants with the same diagnosis.

Methods: Infants with weight loss > or =10% were evaluated for hypernatremia and the ones with serum Na level > or =150 mEq/L were admitted to NICU.

Resuscitation failure due to Fraser syndrome in a newborn undiagnosed in the prenatal period.

Long segment laryngo-tracheal atresia is rare, and is usually incompatible with life in neonates. We report a case of an infant with Fraser syndrome that had not been diagnosed in the prenatal period who presented with impossible intubation due to severe long segment laryngeal atresia in the delivery room. Antenatal diagnostic features of Fraser syndrome and emergency airway management are discussed.

Impact of phototherapy on vasoactive mediators: NO and VEGF in the newborn.

Aim: The objective of this study was to evaluate the effects of close and remote phototherapy on serum nitric oxide (NO) and vascular endothelial growth factor (VEGF) levels as well as on body temperature heart rate and blood pressure in neonates of different gestational ages.

Patients And Method: Term (gestational age > or = 37 weeks) and preterm neonates (GA < 37 weeks) with hyperbilirubinemia requiring phototherapy were included in the study. All patients except for the ones in incubators were randomized to receive either close phototherapy (15 cm above the patient) or remote phototherapy (30-45 cm above patient).
