Chloride Balance in Preterm Infants during the First Week of Life

Objective. To describe the chloride balance in infants born 25-32-week gestation, analyze the association of chloride changes with hydroelectrolytic status and their relationship with perinatal conditions, morbidities, and neurological outcome. Methods. For 7 days after birth, sodium and chloride balance, plasma potassium, phosphate, and total carbon dioxide (tCO(2)) were prospectively determin...

Renal Blood Flow Velocity in Non-Distressed Preterm Infants during the First 72 Hours of Life

Renal blood flow velocity (RBFV) was studied with two­ dimensional/pulsed Doppler ultrasound in 28 non-distressed very preterm infants (mean ± SD gestational age was 27.3 ± 2.1 weeks and birth weight 907 ± 214 g) at 6, 12, 24, 36, 48, and 72 h of age. Mean arterial blood pressure (MABP), PaCC>2 , PaC>2 , and Hct were determined simultaneously. Mean RBFV increased significantly from 14.5 ± 1 . 9...

Renal blood flow velocity in non-distressed preterm infants during the first 72 hours of life.

Renal blood flow velocity (RBFV) was studied with two-dimensional/pulsed Doppler ultrasound in 28 non-distressed very preterm infants (mean +/- SD gestational age was 27.3 +/- 2.1 weeks and birth weight 907 +/- 214 g) at 6, 12, 24, 36, 48, and 72 h of age. Mean arterial blood pressure (MABP), PaCO2, PaO2, and Hct were determined simultaneously. Mean RBFV increased significantly from 14.5 +/- 1....

The RELATIONSHIP BETWEEN ABO BLOOD GROUPS AND SUSCEPTIBILITY TO DIARRHEA IN INFANTS DURING THE FIRST YEAR OF LIFE

Hyponatraemia in the first week of life in preterm infants. Part I. Arginine vasopressin secretion.

Continuous sequential urinary arginine vasopressin measurements in 14 preterm, ventilated infants suggest that both osmoreceptor and volume receptor systems are able to stimulate the prolonged secretion of arginine vasopressin from 26 weeks' gestation. The kidney is able to respond to arginine vasopressin stimulation from the first day of life and from 26 weeks' gestation. A maximum urine osmol...
