Neonatal Complications (neonatal + complications)
Selected AbstractsPregnancy and rare bleeding disordersHAEMOPHILIA, Issue 5 2009R. KADIR Summary., Rare bleeding disorders include deficiency of fibrinogen, prothrombin, factor V, factor VII, factor X, factor XI and factor XIII together with combined deficiency disorders, factor V+VIII deficiency, and deficiency of the vitamin K-dependent factors (factor II, VII, IX and X). They account for 3,5% of all inherited coagulation disorders. Due to their rarity, information about pregnancy complications and management is limited and mostly derived from case reports. Deficiency of fibrinogen and FXIII are both found to be strongly associated with increased risk of recurrent miscarriage and placental abruption. Factor replacement is used to reduce these risks. However, the risk of miscarriage and ante-partum complications is less clear in women with other bleeding disorders. Haemostatic abnormalities in women with rare bleeding disorders seem to persist throughout pregnancy especially if the defect is severe. Therefore women affected with these disorders are at risk of post-partum haemorrhage. The fetus can also be affected and potentially at risk of bleeding complications. Specialised multidisciplinary management is essential to minimise the potential maternal and neonatal complications and ensure an optimal outcome. This paper presents literature review for pregnancy complications in each of the rare bleeding disorders. In addition general principles for management of pregnancy, labour and delivery are discussed. [source] Outcomes of multifetal pregnanciesJOURNAL OF OBSTETRICS AND GYNAECOLOGY RESEARCH (ELECTRONIC), Issue 1 2007Ounjai Kor-anantakul Abstract Aim:, To determine the outcomes of multifetal pregnancies and to compare maternal and neonatal complications between spontaneously conceived and assisted reproductive therapy. Methods:, A retrospective analysis was conducted of the information from medical records relating to all multifetal pregnancies. The outcomes were analyzed and used for a comparison between spontaneous and assisted multifetal pregnancies. Results:, There were 387 multifetal pregnancies during the study period, which was 1.3% of all the deliveries; 334 cases (86.3%) were spontaneous conceptions and 53 cases (13.7%) were the result of assisted reproductive therapy. Higher-order fetuses (,3) represented 8% of all multifetal pregnancies, 13% in the spontaneous group and 87% in the assisted group. The overall cesarean delivery rate was 73.9%. The assisted reproductive therapy group had a cesarean rate of 90.6% compared with 71.3% in the spontaneous group (P = 0.008). The assisted multifetal pregnancy group had more preterm labors and a longer maternal hospital stay than the spontaneous group. One maternal death occurred in the assisted group. The main causes of early neonatal death were prematurity, infection and congenital malformation. The newborns in the assisted group had more complications than the spontaneous group; most notable were respiratory distress syndrome, newborn intensive care admission, infection and longer hospital stay (6 days vs 15 days, P < 0.001). More complications occurred in higher-order fetuses than with twins. Conclusions:, Assisted multifetal pregnancies were more likely to be delivered by cesarean section and had a higher rate of higher-order fetuses, preterm birth and neonatal prematurity-related complications with a longer hospital stay in both mothers and newborns, than spontaneous multifetal pregnancies. [source] Neurodevelopmental outcome in high-risk patients after renal transplantation in early childhoodPEDIATRIC TRANSPLANTATION, Issue 1 2002Erik Qvist Abstract: Patient and graft survival rates of pediatric renal transplant recipients are currently excellent, but there are few reports regarding the long-term neurodevelopmental outcome after renal transplantation (Tx) in early childhood. Children with renal failure from infancy would be expected to have a less favorable developmental prognosis. We report the neurodevelopmental outcome in 33 school-age children transplanted between 1987 and 1995 when < 5 yr of age. We prospectively performed a neurological examination, magnetic resonance imaging (MRI) of the brain, electroencephalograms (EEGs), audiometry, and neuropsychological tests (NEPSY), and measured cognitive performance (WISC-R); we related these results to school performance and to retrospective risk factors prior to Tx. Twenty-six (79%) children attended normal school and 76% had normal motor performance. Six of the seven children attending a special school had brain infarcts on MRI. The EEG was abnormal in 11 (35%), and five (15%) received anti-convulsive treatment after Tx. Sensorineural hearing loss was documented in six patients. The mean intelligence quotient (IQ) was 87, and 6,24% showed impairment in neuropsychological tests. The children attending a special school had been more premature, but had not had a greater number of pre- or neonatal complications. They had experienced a greater number of hypertensive crises (p =,0.002) and seizures (p =,0.03), mainly during dialysis, but the number of septic infections and the mean serum aluminum levels were not significantly greater than in the children with normal school performance. In these previously lethal diseases, the overall neurodevelopmental outcome is reassuring. However, it is of crucial importance to further minimize the risk factors prior to Tx. [source] Maternal and neonatal outcomes in 54 triplet pregnancies managed in an Australian tertiary centreAUSTRALIAN AND NEW ZEALAND JOURNAL OF OBSTETRICS AND GYNAECOLOGY, Issue 3 2004Andrea BARKEHALL-THOMAS Abstract Background:, To provide current data on maternal and neonatal outcomes in triplet pregnancies in an Australian population. Methods:, Retrospective case note review of all triplet pregnancies managed within a single Australian tertiary centre. Results:, Fifty-four sets of triplets were managed from January 1996 to October 2002. A total of 59% resulted from the use of assisted reproductive technologies. The median gestation at delivery was 32.5 weeks (range: 21,36 weeks); 14% delivered prior to 28 weeks and 43% delivered before 32 weeks. Preterm labour and preterm rupture of membranes were the most common antenatal complications occurring in 57 and 22% of pregnancies, respectively. A total of 93% of pregnancies were delivered by Caesarean section and 37% of mothers experienced at least one post-partum complication. A total of 96% of neonates were liveborn, with a median birthweight of 1644 g (range: 165,2888 g). The two most common neonatal complications were jaundice and hypoglycaemia in 52 and 43% of liveborn neonates, respectively. A total of 28% of neonates were below the 10th centile for gestational age and sex. A total of 8% of neonates demonstrated congenital anomalies. The perinatal mortality at a gestational age of 20,24 weeks was 100%, 22% at 25,28 weeks and zero for those babies born at 29 weeks or beyond. Conclusion:, Assisted reproductive technologies contribute significantly to the incidence of triplet pregnancies. Gestational age at delivery and perinatal mortality is comparable to published international data. Triplets born in a tertiary centre beyond 28 weeks gestation have a very favourable prognosis in the newborn period. [source] Evidence-Based Strategies for Reducing Cesarean Section Rates: A Meta-AnalysisBIRTH, Issue 1 2007Nils Chaillet PhD ABSTRACT: Background: Canada's cesarean section rate reached an all-time high of 22.5 percent of in-hospital deliveries in 2002 and was associated with potential maternal and neonatal complications. Clinical practice guidelines represent an appropriate mean for reducing cesarean section rates. The challenge now lies in implementing these guidelines. Objectives of this meta-analysis were to assess the effectiveness of interventions for reducing the cesarean section rate and to assess the impact of this reduction on maternal and perinatal mortality and morbidity. Methods: The Cochrane Library, EMBASE, and MEDLINE were consulted from January 1990 to June 2005. Additional studies were identified by screening reference lists from identified studies and expert suggestions. Studies involving rigorous evaluation of a strategy for reducing overall cesarean section rates were identified. Randomized controlled trials, controlled before-and-after studies, and interrupted time series studies were evaluated according to Effective Practice and Organisation of Care Group criteria. Results: Among the 10 included studies, a significant reduction of cesarean section rate was found by random meta-analysis (pooled RR = 0.81 [0.75, 0.87]). No evidence of publication bias was identified. Audit and feedback (pooled RR = 0.87 [0.81, 0.93]), quality improvement (pooled RR = 0.74 [0.70, 0.77]), and multifaceted strategies (pooled RR=0.73 [0.68, 0.79]) were effective for reducing the cesarean section rate. However, quality improvement based on active management of labor showed mixed effects. Design of studies showed a higher effect for noncontrolled studies than for controlled studies (pooled RR = 0.76 [0.72, 0.81] vs 0.92 [0.88, 0.96]). Studies including an identification of barriers to change were more effective than other interventions for reducing the cesarean section rate (pooled RR = 0.74 [0.71, 0.78] vs 0.88 [0.82, 0.94]). Among included studies, no significant differences were found for perinatal and neonatal mortality and perinatal and maternal morbidity with respect to the mode of delivery. Only 1 study showed a significant reduction of neonatal and perinatal mortality (p < 0.001). Conclusions: The cesarean section rate can be safely reduced by interventions that involve health workers in analyzing and modifying their practice. Our results suggest that multifaceted strategies, based on audit and detailed feedback, are advised to improve clinical practice and effectively reduce cesarean section rates. Moreover, these findings support the assumption that identification of barriers to change is a major key to success. (BIRTH 34:1 March 2007) [source] Selected neonatal outcomes in dizygotic twins after IVF versus non-IVF pregnanciesBJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 6 2010B Källén Please cite this paper as: Källén B, Finnström O, Lindam A, Nilsson E, Nygren K-G, Otterblad Olausson P. Selected neonatal outcomes in dizygotic twins after IVF versus non-IVF pregnancies. BJOG 2010; Objective, To compare neonatal outcome among twins conceived after in vitro fertilisation (IVF) with that of spontaneously conceived twins. Design, Comparison of different-sex (dizygotic) twins born after IVF with non-IVF dizygotic twins. Setting, National health registers in Sweden. Population, All births in Sweden during the period 1982,2007. Methods, We studied gestational duration, lowest birthweight and birthweight difference in the twin pair, presence of one or two twins with a respiratory complication, and with jaundice in one or both twins. Risk estimates were calculated as odds ratios with adjustments for year of birth, maternal age, parity and smoking in pregnancy. Main outcome measures, Gestational duration, birth weight, respiratory complications, jaundice. Results, We studied 1545 pairs of dizygotic twins born after IVF, and 8675 pairs of dizygotic twins where IVF was not known to have occurred. The risk for preterm delivery before 32 weeks of gestation was significantly increased among dizygotic twin pairs born after IVF compared with non-IVF dizygotic twin pairs. No significant difference in low birthweight or birthweight difference within twin pairs was seen. There was an increased occurrence of twin pairs with respiratory problems or jaundice, but only the latter diagnosis occurred in a statistically significant excess. Conclusions, The study confirms recent findings that IVF is associated with an increased risk for some neonatal complications, not only among singletons but also among twins. [source] Titrated low-dose vaginal and/or oral misoprostol to induce labour for prelabour membrane rupture: a randomised trialBJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 12 2008L Bricker Objective, To evaluate the clinical effectiveness and safety of titrated low-dose misoprostol for induction of labour (IOL) in the presence of prelabour rupture of membranes (PROM). Design, Randomised controlled trial. Setting, Maternity units in the UK (9) and Egypt (1). Population, Women >34 weeks of gestation with PROM, singleton viable fetus and no previous caesarean section. Methods, Subjects randomised to IOL with a titrated low-dose misoprostol regimen (oral except if unfavourable cervix, where initial dose vaginal) or a standard induction method, namely vaginal dinoprostone followed by intravenous oxytocin if the cervix was unfavourable or intravenous oxytocin alone if the cervix was favourable. Main outcome measures, Primary outcome measures were caesarean section and failure to achieve vaginal delivery within 24 hours. Analysis was by intention to treat. Results, The trial did not achieve the planned sample size of 1890 due to failure in obtaining external funding. Seven hundred and fifty-eight women were randomised (375 misoprostol and 383 standard). There were less caesarean section (14 versus 18%, relative risk [RR] 0.79; 95% CI 0.57,1.09) and less women who failed to achieve vaginal delivery within 24 hours in the misoprostol group (24 versus 31%, RR 0.79; 95% CI 0.63,1.00), but the differences were not statistically significant. Subgroup analysis showed that with unfavourable cervix, misoprostol may be more effective than vaginal dinoprostone. There was no difference in hyperstimulation syndrome. There were more maternal adverse effects with misoprostol, but no significant differences in maternal and neonatal complications. Conclusions, Titrated low-dose misoprostol may be a reasonable alternative for IOL in the presence of PROM, particularly in women with an unfavourable cervix. Safety and rare serious adverse events could not be evaluated in a trial of this size. [source] Pregnancy outcome in women with heart disease undergoing induction of labourBJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 7 2004Galia Oron Objective To examine the safety and outcome of induction of labour in women with heart disease. Design Prospective single-centre comparative study. Setting Major university-based medical centre. Population/Sample One hundred and twenty-one pregnant women with heart disease. Methods The sample included all women with acquired or congenital heart disease who attended our High-Risk Pregnancy Outpatient Clinic from 1995 to 2001. The files were reviewed for baseline data, cardiac and obstetric history, course of pregnancy and induction of labour and outcome of pregnancy. Findings were compared between women who underwent induction of labour and those who did not. Forty-seven healthy women in whom labour was induced for obstetric reasons served as controls. Main outcome measures Pregnancy outcome. Results Of the 121 women with heart disease, 47 (39%) underwent induction of labour. There was no difference in the caesarean delivery rate after induction of labour between the women with heart disease (21%) and the healthy controls (19%). Although the women with heart disease had a higher rate of maternal and neonatal complications than controls (17%vs 2%, P= 0.015), within the study group, there was no difference in complication rate between the patients who did and did not undergo induction of labour. Conclusion Induction of labour is a relatively safe procedure in women with cardiac disease. It is not associated with a higher rate of caesarean delivery than in healthy women undergoing induction of labour for obstetric indications, or with more maternal and neonatal complications than in women with a milder form of cardiac disease and spontaneous labour. [source] Optic nerve hypoplasia in North America: a re-appraisal of perinatal risk factorsACTA OPHTHALMOLOGICA, Issue 5 2010Pamela Garcia-Filion Abstract. Purpose:, The purpose of this study is to describe and clarify the birth and prenatal characteristics of a large cohort of children with optic nerve hypoplasia. Methods:, This is a descriptive report of 204 patients aged , 36 months and enrolled in a prospective study at the Children's Hospital Los Angeles. Birth characteristics, including complications, were abstracted from study files and medical records. Systematic maternal interviews were conducted to obtain detailed prenatal histories. National birth data were used for comparison with birth findings. Results:, Birth characteristics were unremarkable for birthweight and gestation, but significant for increased frequency of caesarean delivery and fetal and neonatal complications. Young maternal age and primaparity were dominating maternal features. Preterm labour, gestational vaginal bleeding, low maternal weight gain and weight loss during pregnancy were prevalent. Conclusions:, These findings confirm young maternal age and primaparity as associated risk factors, challenge many other suggested factors such as alcohol and drug abuse, and introduce potentially significant prenatal characteristics such as maternal weight loss and early gestational vaginal bleeding as aetiological correlates. [source] Most very low birth weight subjects do well as adultsACTA PAEDIATRICA, Issue 9 2009P-O Gäddlin Abstract Aim:, To study health, quality of life, educational level and occupation in very low birth weight (VLBW) children in early adulthood and the relationship of the findings to neonatal risk factors and later handicap. Methods:, This is a prospective long-term follow-up study of a regional cohort of 20-year-old VLBW subjects (n = 77) of all surviving VLBW children (n = 86) and 69/86 term controls born in 1987,1988 in the south-east of Sweden. Postal questionnaires were used: 1. A study-specific form, 2. Medical Outcomes Study, Short Form (SF-36), 3. Sense of Coherence. Results:, VLBW subjects did not differ significantly from their controls in self-perceived health, use of tobacco, education, occupation and way of living, or scoring on SF-36 and Sense of Coherence. Sixteen had cerebral palsy, attention deficit hyperactivity disorder or isolated mental retardation, and these subjects differed significantly from controls on SF-36 in physical functioning and physical health score, but not on Sense of Coherence. VLBW subjects were significantly lighter and shorter than their controls. Extremely low birth weight (ELBW), bronchopulmonary dysplasia and intraventricular haemorrhage were significantly associated with poorer scores on physical function. Conclusion:, The 20-year old VLBW subjects reported perceived health and managed transition to adulthood similar to controls. Handicapped subjects had poorer self-perceived physical function. ELBW and severe neonatal complications were associated with poorer self-perceived physical health. [source] Comparative outcome study between triplet and singleton preterm newbornsACTA PAEDIATRICA, Issue 11 2002A Maayan-Metzger Aim: To evaluate the outcome of triplet versus singleton preterm newborns. Methods: The study population included 64 sets of preterm triplet (gestational age 25-34 wk) and 64 singleton controls. Data on prenatal and perinatal findings, neonatal complications, duration of hospitalization, and neonatal mortality were collected by chart review. Results: Mothers of triplets were more likely to receive prenatal tocolytic treatment and more antenatal steroids for foetal lung maturation, and to be delivered by caesarean section. No differences were found between the groups in perinatal parameters (cord pH, Apgar score, respiratory support after birth), respiratory parameters (severity of acute and chronic lung disease, use and duration of oxygen treatment and assisted ventilation), or neonatal complications (patent ductus arteriosus, intraventricular haemorrhage, periventricular leukomalacia, necrotizing enterocolitis, retinopathy of prematurity, meningitis, sepsis and jaundice). This was also true for duration of hospitalization and neonatal mortality. No differences were recorded by birth order among the triplets for any of these parameters. Conclusion: The study indicates that good prenatal care can lead to a good outcome for preterm triplets, close to that of preterm singleton infants. Families and physicians should consider this information when foetal reduction is offered. [source] | ||||||||||
