Most published reports indicate that intensified hemodialysis results in better pregnancy outcomes. Here we studied clinical characteristics and the outcomes of 28 pregnant women receiving hemodialysis. We found an association between maternal blood data and birth weight, and gestational age and outcomes. There were 18 surviving infants who were followed up for one year. In the others there were 4 spontaneous abortions, 1 stillbirth, 3 neonatal deaths and 2 deaths after birth. Analysis of blood chemistry for 20 pregnancies from 12 weeks of gestation until delivery showed that the average hemoglobin level was significantly higher in the group that successfully delivered than in the unsuccessful group. There were significant negative relationships between the blood urea nitrogen (BUN) level and the birth weight or gestational age in the latter cohort. A birth weight equal to or greater than 1500 g or a gestational age equal to or exceeding 32 weeks corresponded to BUN levels of 48-49 mg/dl or less. Whether the low BUN is the direct cause of the improved outcome remains to be examined.
Preeclampsia with FGR is severe condition which can possibly adversely affect the maternal condition. About 15% of all mothers diagnosed with FGR developed preeclampsia afterwards; therefore, those with FGR are considered to be candidates for close monitoring for the clinical manifestation of preeclampsia, and those with early-onset FGR with proteinuria may represent a high-risk group for preeclampsia.
Aim. To clarify the effect of perinatal events on the survival of ELBW infants in Japan. Methods. 1,713 ELBW infants, from 92,630 live births in 2001 and 2002, born at 22–36 weeks of gestation were registered. Case was defined as death at discharge. The relevant variables were compared between the cases (n = 366) and the controls (n = 1,347). Results. The total survival rate was 78.6%. There was a significant difference between the survival rate in cesarean and vaginal delivery at 24–31 weeks of gestation. Cesarean delivery in infants with a birth weight >400 g was significantly advantageous to the survival rate of ELBW infants than vaginal delivery. The significant contributing factors were gestational age at delivery (OR: 0.97), Apgar score at 5 min (0.56), antenatal steroid (0.41), and birth weight (0.996). Nonvertex presentation (1.81), vaginal delivery (1.56), and placental abruption (2.50) were found to be significantly associated with neonatal death. Conclusions. Cesarean section might be advantageous for survival in ELBW infants over 24 gestational weeks or 400 grams of birth weight. Nonvertex presentation, vaginal delivery, and placental abruption could be significant risk factors for survival of ELBW infants.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
