A study was carried out to assess the effects of immediate postoperative oral rehydration in 51 unpremedicated women undergoing caesarean section under epidural anesthesia. The patients were randomly assigned to 2 groups: group 1 (n = 22)--fasting at least until 24 hours after the end of the operation, and group 2 (n = 29)--receiving immediate [...]

Although the mechanisms responsible for the onset of preterm labor in human pregnancy are unclear, animal studies have demonstrated that decreased nutrient intake is associated with increased uterine prostaglandin F metabolite production and spontaneous uterine contractions. The purpose of this study was to assess the association of maternal nutrition and dehydration with preterm uterine contractility. [...]

Fetal renal pyelectasis is a frequent finding on routine obstetrical sonography. The cause of this pelvocalyceal dilatation is often not apparent, although urinary tract obstruction is the most important condition to be excluded. One of the many hypothetical explanations for minimal fetal renal pyelectasis suggests that aggressive maternal hydration before sonography leads to fetal diuresis [...]

BACKGROUND: Hypernatremic dehydration amongst exclusively breastfed neonates due to inadequate breastfeeding or underfeeding is a potentially devastating condition. We investigated the epidemiological and clinic features of hypernatremic dehydration. METHODS: We retrospectively reviewed the medical records of neonates that were less than 28 days of age, weighing > or =2000 g with gestational age of 36 [...]

OBJECTIVE: To determine the long-term outcome of neonatal dehydration. STUDY DESIGN: We identified 182 newborns who were rehospitalized with dehydration (weight loss > or =12% of birth weight and/or serum sodium > or =150 mEq/L) and 419 randomly selected controls from a cohort of 106,627 term and near-term infants with birth weight > or =2000 [...]

Neurologic damage secondary to dehydration occurs in one of two ways; there can be circulatory shock with hypoxic damage, or a hypernatremic state with cerebral hemorrhage and sometimes thrombosis. The shock variety is most often seen after massive water and electrolyte losses from diarrheal disease; the hypernatremic variety has also been mostly seen in diarrheal [...]

Severe neonatal hypernatremia is an important electrolyte disorder that has serious effects on the central nervous system, including brain edema, intracranial hemorrhage, hemorrhagic infarct, and thrombosis. Cerebral venous thrombosis is relatively rare in severe neonatal hypernatremic dehydration. The English literature contains only a few reports of the cranial radiological findings in severe neonatal hypernatremia. The [...]

AIMS: To ascertain the effect of a policy of early weighing on the detection and severity of neonatal hypernatraemic dehydration (NHD) and on breastfeeding rates in the short and medium term. METHODS: A policy of weighing infants at 72-96 h was introduced from 1 July 2004. Two time periods were studied: pre-policy and post-policy (18 [...]

OBJECTIVES: To determine the incidence of neonatal dehydration leading to rehospitalization, whether clinical and health services data could predict its occurrence, and the outcome of dehydrated infants. METHODS: We employed a retrospective case-control design nested within a cohort of 51 383 newborns weighing 2000 g or more, with a gestational age of 36 weeks or [...]
