Neonatal Outcomes (neonatal + outcome)
Kinds of Neonatal Outcomes Selected AbstractsCommunity-based, Prospective, Controlled Study of Obstetric and Neonatal Outcome of 179 Pregnancies in Women with EpilepsyEPILEPSIA, Issue 1 2006Katriina Viinikainen Summary:,Purpose: This study evaluated obstetric and neonatal outcome in a community-based cohort of women with active epilepsy (WWAE) compared with the general pregnant population receiving modern obstetric care. Methods: We reviewed the total population who gave birth between January 1989 and October 2000 at Kuopio University Hospital. Obstetric, demographic, and epilepsy data were collected prospectively from 179 singleton pregnancies of women with epilepsy and from 24,778 singleton pregnancies of unaffected controls. The obstetric data from the pregnancy register was supplemented with detailed neurologic data retrieved from the medical records. The data retrieved were comprehensive because of a follow-up strategy according to a predecided protocol. Results: During pregnancy, the seizure frequency was unchanged, or the change was for the better in the majority (83%) of the patients. We found no significant differences between WWAE and controls in the incidence of preeclampsia, preterm labor, or in the rates of caesarean sections, perinatal mortality, or low birth weight. However, the rate of small-for-gestational-age infants was significantly higher, and the head circumference was significantly smaller in WWAE. Apgar score at 1 min was lower in children of WWAE, and the need for care in the neonatal ward and neonatal intensive care were increased as compared with controls. The frequency of major malformations was 4.8% (,0.6,10.2%; 95% confidence interval) in the 127 children of WWAE. Conclusions: Pregnancy course is uncomplicated and neonatal outcome is good in the majority of cases when a predecided protocol is used for the follow-up of WWAE in antenatal and neurologic care. Long-term follow-up of the neurologic and cognitive development of the children of WWAE is still needed. [source] Effects of Oral L-Arginine on the Foetal Condition and Neonatal Outcome in Preeclampsia: A Preliminary ReportBASIC AND CLINICAL PHARMACOLOGY & TOXICOLOGY, Issue 2 2006Krzysztof Rytlewski Randomized, placebo-controlled, double-blind, clinical trial. Oral therapy with 3 g of L-arginine daily or placebo as a supplement to standard therapy. Eighty-three preeclamptic women, randomly assigned to the L-arginine (n=42) or placebo (n=41) groups; [n=30 (L-arginine) and n=31 (placebo) ended the study, respectively]. Foetal gain chances due to ultrasound biometry, biophysical profile, Doppler velocimetry of pulsatility indices of umbilical and middle cerebral arteries, cerebro-placental ratio, as well as differences in duration of pregnancy and clinical data of newborn. L-arginine treatment transitory accelerated foetal gain and improved biophysical profile. Starting from 3rd week of therapy, the umbilical artery pulsatility indices values were significantly lower in L-arginine than in placebo group. Moreover, treatment with L-arginine caused significant increase of middle cerebral artery pulsatility indices and cerbro-placental ratio values. Latency was longer in L-arginine group. Neonates delivered in the L-arginine group revealed higher Apgar score. Supplementary treatment with oral L-arginine seems to be promising in improving foetal well-being and neonatal outcome as well as in prolonging pregnancy complicated with preeclampsia. However, these benefits require confirmation in more-powered, larger studies.

Fisler EdM MD ABSTRACT: Background: Trial of labor after cesarean section has been an important strategy for lowering the rate of cesarean delivery in the United States, but concerns regarding its safety remain. The purpose of this study was to evaluate the outcome of newborns delivered by elective repeat cesarean section compared to delivery following a trial of labor after cesarean. Methods: All low-risk mothers with 1 or 2 previous cesareans and no prior vaginal deliveries, who delivered at our institution from December 1994 through July 1995, were identified. Neonatal outcomes were compared between 136 women who delivered by elective repeat cesarean section and 313 women who delivered after a trial of labor. To investigate reasons for differences in outcome between these groups, neonatal outcomes within the trial of labor group were then compared between those mothers who had received epidural analgesia (n = 230) and those who did not (n = 83). Results: Infants delivered after a trial of labor had increased rates of sepsis evaluation (23.3% vs 12.5%, p = 0.008); antibiotic treatment (11.5% vs 4.4%, p = 0.02); intubation to evaluate for the presence of meconium below the cords (11.5% vs 1.5%, p < 0.001); and mild bruising (8.0% vs 1.5%, p = 0.008). Within the trial of labor group, infants of mothers who received epidural analgesia were more likely to have received diagnostic tests and therapeutic interventions including sepsis evaluation (29.6% vs 6.0%, p = 0.001) and antibiotic treatment (13.9% vs 4.8%, p = 0.03) than within the no-epidural analgesia group. Conclusions: Infants born to mothers after a trial of labor are twice as likely to undergo diagnostic tests and therapeutic interventions than infants born after an elective repeat cesarean section, but the increase occurred only in the subgroup of infants whose mothers received epidural analgesia for pain relief during labor. The higher rate of intervention could relate to the well-documented increase in intrapartum fever that occurs with epidural use. (BIRTH 30:2 June 2003) [source] Oral nifepidine versus subcutaneous terbutaline tocolysis for external cephalic version: a double-blind randomised trialBJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 1 2009R Collaris Objective, To evaluate oral nifedipine versus subcutaneous terbutaline tocolysis for external cephalic version (ECV). Design, A double-blind randomised trial. Setting, A university hospital in Malaysia. Population, Non-labouring women with a term singleton fetus in breech presentation or transverse lie suitable for elective ECV. Methods, Participants were randomised to either 10 mg oral nifedipine tablet and subcutaneous saline placebo or oral placebo tablet and 250 microgram bolus terbutaline subcutaneously. Participants and providers were blinded. Ultrasound assessment and cardiotocogram were performed prior to ECV. ECV was commenced 20,30 minutes after treatment. A maximum of two ECV attempts were permitted. Elective caesarean delivery or a repeat ECV attempt at a later date was offered to participants following failed ECV. After successful ECV, management was expectant. Main outcome measures, Primary outcomes were successful ECV (cephalic presentation immediately after ECV) and caesarean delivery. Results, Ninety women were randomised: 44 to nifedipine and 46 to terbutaline. Initial ECV success rate was 15/44 (34.1%) versus 24/46 (52.2%) (relative risk [RR] 0.7, 95% CI 0.4,1.1; P= 0.094), and caesarean delivery rate was 34/44 (77.3%) versus 26/46 (56.5%) (RR 1.4, 95% CI 1.01,1.85; numbers needed to treat to benefit 5, 95% CI 2.5,55; P= 0.046) for nifedipine and terbutaline groups, respectively. Neonatal outcome was not different. Conclusions, Bolus subcutaneous terbutaline tocolysis for ECV compared with oral nifedipine resulted in less caesarean deliveries. ECV success rate was not significantly higher. Larger studies are indicated. [source] Neonatal outcome following pregnancy exposure to antidepressants: a prospective controlled cohort studyBJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 2 2008S Maschi Objective, To determine the incidence of early adverse effects associated with antidepressant drug use during pregnancy. Design, Prospective, controlled cohort study. Setting, A Drug and Health Information Centre in Milan, Italy. Population, A total of 200 neonates exposed to antidepressants in utero and 1200 controls. Methods, Women who took antidepressants during pregnancy and delivered liveborn children between 1995 and 2003 were selected. Each case was matched for maternal age and gravidity to six randomly selected controls (not exposed to teratogenic drugs or drugs known to cause neonatal side effects). Odds ratio was estimated for attributable risks. Main outcome measures, Neonatal adverse events and Special Care Unit admission rate, assessed through an interview with the mothers. Results, Of the 200 neonates exposed to antidepressants in utero, 14 had adverse events and 3 required Special Care Unit admission. Jaundice (n = 5), agitation (n = 3) and respiratory distress (n = 2) were the most common symptoms. In the control group, 50 newboms had side effects and no statistically significant differences in the prevalence rate compared to the exposed group were found, even after stratification for drugs and pregnancy period of exposure. Only the prematurity rate was significantly higher in exposed compared to non-exposed newborns (OR = 2.31; 95% CI 1.14,4.63). Conclusions, These results do not support an association between antidepressant exposure and unsafe fetal and neonatal outcomes in newborns. However, a collaborative international multicentre epidemiological monitoring of the use of psychotropic drugs during pregnancy is needed in order to guarantee pregnant women and their children safe and effective treatments, both at brief and long time from exposure.

(BIRTH 30:2 June 2003) [source] Immersion in Water in the First Stage of Labor: A Randomized Controlled TrialBIRTH, Issue 2 2001Kerena Eckert RN Background:Current forms of analgesia often have significant side effects for women in labor. Bathing in warm water during labor has been reported to increase a woman's comfort level and cause a reduction in painful contractions. The objective of this trial was to compare immersion in warm water during labor with traditional pain management for a range of clinical and psychological outcomes.Methods:A prospective randomized controlled trial of 274 pregnant women, who were free from medical and obstetric complications and expecting a singleton pregnancy at term, was conducted at the Women's and Children's Hospital, a maternity tertiary referral center in Adelaide, South Australia. Women in labor were randomized to an experimental group who received immersion in a bath or to a nonbath group who received routine care. Pharmacological pain relief was the primary outcome that was measured, and secondary outcomes included maternal and neonatal clinical outcomes, factors relating to maternal and neonatal infectious morbidity, psychological outcomes, and satisfaction with care.Results:The use of pharmacological analgesia was similar for both the experimental and control groups; 85 and 77 percent, respectively, used major analgesia. No statistical differences were observed in the proportion of women requiring induction and augmentation of labor or in rates of perineal trauma, length of labor, mode of delivery, or frequency of cardiotocographic trace abnormalities. Neonatal outcomes (birthweight, Apgar score, nursery care, meconium-stained liquor, cord pH estimations) revealed no statistically significant differences. Infants of bath group women required significantly more resuscitation than routine group women. Routine group women rated their overall experience of childbirth more positively than bath group women. Psychological outcomes, such as satisfaction with care or postnatal distress, were the same for both groups.Conclusion:Bathing in labor confers no clear benefits for the laboring woman but may contribute to adverse effects in the neonate. [source] Assessing teratogenicity of antiretroviral drugs: monitoring and analysis plan of the Antiretroviral Pregnancy Registry,,PHARMACOEPIDEMIOLOGY AND DRUG SAFETY, Issue 8 2004Deborah L. Covington DrPH Abstract This paper describes the Antiretroviral Pregnancy Registry's (APR) monitoring and analysis plan. APR is overseen by a committee of experts in obstetrics, pediatrics, teratology, infectious diseases, epidemiology and biostatistics from academia, government and the pharmaceutical industry. APR uses a prospective exposure-registration cohort design. Clinicians voluntarily register pregnant women with prenatal exposures to any antiretroviral therapy and provide fetal/neonatal outcomes. A birth defect is any birth outcome ,20 weeks gestation with a structural or chromosomal abnormality as determined by a geneticist. The prevalence is calculated by dividing the number of defects by the total number of live births and is compared to the prevalence in the CDC's population-based surveillance system. Additionally, first trimester exposures, in which organogenesis occurs, are compared with second/third trimester exposures. Statistical inference is based on exact methods for binomial proportions. Overall, a cohort of 200 exposed newborns is required to detect a doubling of risk, with 80% power and a Type I error rate of 5%. APR uses the Rule of Three: immediate review occurs once three specific defects are reported for a specific exposure. The likelihood of finding three specific defects in a cohort of ,600 by chance alone is less than 5% for all but the most common defects. To enhance the assurance of prompt, responsible, and appropriate action in the event of a potential signal, APR employs the strategy of ,threshold'. The threshold for action is determined by the extent of certainty about the cases, driven by statistical considerations and tempered by the specifics of the cases.

[source] Care and Outcome of Out-of-hospital DeliveriesACADEMIC EMERGENCY MEDICINE, Issue 7 2000Harry C Moscovitz MD Abstract. Objectives: To identify interventions by paramedics in out-of-hospital deliveries and predictors of neonatal outcome. Methods: A prospective case series of consecutive out-of-hospital deliveries at Yale-New Haven Hospital from January 1991 to January 1994. Data describing out-of-hospital interventions, demographics, maternal risk factors, and neonatal outcomes were collected from out-of-hospital, emergency department (ED), and hospital records. Subgroups defined by source of prenatal care were compared using a multiple logistic regression model to determine predictors of poor neonatal outcome. Results: Ninety-one patients presented to the hospital after delivery. Paramedics attended 78 (86%) of the cases. Paramedics performed endotracheal intubation in one neonate and supported ventilation in four others. Suctioning and warming of the neonate were documented in 58% and 76%, respectively, and hypothermia was common (47%) in the paramedicattended deliveries. There were 9 neonatal deaths. Eight (89%) of the neonatal deaths were in the group with no prenatal care (p < 0.0001). Lack of prenatal care (RR 304, 95% CI = 5.0 to 18,472) and history of poor prenatal care (RR 22.5, 95% CI = 1.19 to 427) were significant predictors of poor neonatal outcome. Sixteen percent of all study patients and 43% of those with no prenatal care were treated in the ED during their pregnancies. Eighteen percent of the patients had had no prenatal care during previous pregnancies. Conclusions: Paramedics manage labor and delivery of a high-risk population. Fundamental aspects of care were not universally documented. Lack of prenatal care was associated with high neonatal morbidity and mortality. Nearly half of the mothers who went on to deliver without prenatal obstetric care saw emergency physicians during their pregnancies. [source] Is neonatal risk from vasa previa preventable?JOURNAL OF CLINICAL ULTRASOUND, Issue 3 2010The 20-year experience from a single medical center Abstract Background. Vasa previa is a rare condition associated with neonatal morbidity and mortality that may be diagnosed prenatally using transvaginal sonography. The aim of this study was to assess the prenatal detection of vasa previa and its subsequent impact on neonatal outcomes in two 10-year periods (1988,1997 versus 1998,2007). Method. Retrospective review of all cases of vasa previa. Data on obstetrical history, modes of conception, sonographic scans, delivery mode, and neonatal outcome were retrieved and recorded. Result. There were 19 pregnancies (21 neonates) with confirmed vasa previa (overall incidence of 1.7/10,000 deliveries). Vasa previa were diagnosed prenatally in 10 (52.6%) cases. In cases without prenatal diagnosis, there was a higher proportion of neonates with 1, Apgar score ,5 and cord blood pH <7 compared with cases diagnosed prenatally (66.7% versus 10%, p , 0.05, and 33.3% versus 0%, p < 0.05, respectively). The prenatal detection rate of vasa previa increased from 25 to 60% between the 2 time periods (p > 0.05), whereas perinatal mortality and 1, Apgar scores ,5 decreased from 25 to 0% and from 50 to 33.3% (p > 0.05). Conclusion. Prenatal sonographic screening using targeted scans for vasa previa in women at risk or as part of routine mid-gestation scanning may significantly impact its obstetric manifestations. © 2010 Wiley Periodicals, Inc. J Clin Ultrasound, 2010 [source] Three-dimensional sonographic measurement of contralateral lung volume in fetuses with isolated congenital diaphragmatic hernia,JOURNAL OF CLINICAL ULTRASOUND, Issue 5 2008Rodrigo Ruano MD Abstract Purpose To use 3-dimensional sonography (3DUS) to measure contralateral lung volume and evaluate the potential of this measurement to predict neonatal outcome in isolated congenital diaphragmatic hernia (CDH). Methods Between January 2002 and December 2004, the contralateral lung volumes of 39 fetuses with isolated CDH were measured via 3DUS using rotational multiplanar imaging. The observed/expected contralateral fetal lung volume ratios (o/e-ContFLVR) were compared with the lung/head ratio (LHR), observed/expected total fetal lung volume ratio (o/e-TotFLVR), and postnatal outcome. Results Contralateral lung volumes are less reduced than total lung volumes in CDH. The bias and precision of 3DUS in estimating contralateral lung volumes were 0.99 cm3 and 1.11 cm3, respectively, with absolute limits of agreement ranging from ,1.19 cm3 to +3.17 cm3. The o/e-ContFLVR was significantly lower in neonatal death cases (median, 0.49 cm3; range, 0.22,0.99 cm3) than in survival cases (median, 0.58 cm3; range, 0.42,0.92 cm3 [p < 0.01]). Overall accuracy of the o/e-ContFLVR, o/e-TotFLVR, and LHR in predicting neonatal death were 67.7% (21/31), 80.7% (25/31), and 77.4% (24/31), respectively. Conclusion Although o/e-ContFLVR can be precisely measured with 3DUS and can be used to predict neonatal death in CDH, it is less accurate than LHR and o/e-TotFLVR for that purpose. © 2007 Wiley Periodicals, Inc. J Clin Ultrasound, 2008 [source] Neonatal C-reactive protein value in prediction of Outcome of Preterm Premature Rupture of Membranes: Comparison of Singleton and Twin PregnanciesJOURNAL OF OBSTETRICS AND GYNAECOLOGY RESEARCH (ELECTRONIC), Issue 4 2009Simin Taghavi Abstract Aim:, The clinical importance of preterm premature rupture of the membranes (PPROM) is its relationship to maternal and neonatal mortality and morbidity, especially in twin pregnancies. The aim of this study was to determine and compare the role of inflammatory factors as predictors of the PPROM outcome between singleton and twin pregnancies. Methods:, The medical records of 22 twins delivered between 28 and 34 weeks and complicated by PPROM were reviewed at the Al-Zahra Hospital in Tabriz, Iran. Also among singletons, 55 cases of matched gestational age were randomly selected as a control group. Three laboratory indices of neonatal white blood cell (WBC) count and C-reactive protein (CRP) in the two groups were measured immediately after delivery and the effects of two factors on neonatal outcome were assessed. Results:, In singletons, there was adverse relationship between the mean of WBC count and duration of latency (P = 0.007). Also, a positive relationship between the means of ventilation time and WBC count in second twins was found (P = 0.034). Positive CRP was the main predictor of neonatal intensive care unit admission in both singletons (odds ratio: 4.929, P = 0.042) and first twins (odds ratio: 9.000, P = 0.005). However, positive CRP did not influence the existence of metabolic acidosis or duration of latency in either of the two groups. Conclusion:, Neonatal WBC count was a predictor for the duration of latency in singletons and for ventilation time in twins. Positive neonatal CRP was an important factor for the prediction of neonatal intensive care unit admission in both types of pregnancy; its role in twins is clearer than in singletons. [source] Effect of Labour and Delivery on Plasma Hepatic Enzymes in the NewbornJOURNAL OF OBSTETRICS AND GYNAECOLOGY RESEARCH (ELECTRONIC), Issue 1 2000Dr. Max Mongelli Abstract Objective: To study the relationship between cord blood hepatic enzymes and obstetric and neonatal outcome in a Chinese population. Materials and Methods: The study group consisted of 288 low-risk Chinese women with singleton term pregnancies. The following enzymes were assayed in cord blood: lactate dehydrogenase (LDH), glutamyl transferase (GGT), aspartate aminotransferase (AST) and alanine transferase (ALT). These were correlated to maternal and neonatal characteristics. Results: A strong correlation was noted between cord blood AST and LDH (R = 0.582, p < 0.01), which was absent amongst those infants delivered by elective cesarean section. LDH, AST and ALT were negatively correlated with cord arterial pH and base excess (BE). GGT was inversely related only to gestational age (R = - 0.18, p < 0.01). Both LDH and AST were weakly correlated with the duration of the first and second stages of labour. LDH was most closely linked to arterial pH, whereas AST was related to both arterial BE and duration of the second stage. Conclusions: The reference values are comparable to those published for Caucasian populations. There are moderate elevations in LDH and AST associated with the onset of labour and changes in acid-base status. [source] Effect of delayed supine positioning after induction of spinal anaesthesia for caesarean sectionACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 4 2002F. Køhler Background: The study tested the hypothesis that the incidence of hypotension during spinal anaesthesia for caesarean section is less in parturients who remain in the sitting position for 3 min compared with parturients who are placed in the modified supine position immediately after induction of spinal anesthesia. Methods: Spinal anaesthesia was induced with the woman in the sitting position using 2.8 ml hyperbaric bupivacaine 0.5% at the L3,4 or L2,3 interspace. Ninety-eight patients scheduled for elective caesarean section under spinal anaesthesia were randomised to assume the supine position on an operating table tilted 10° to the left (modified supine position) immediately after spinal injection (group 0, n=52) or to remain in the sitting position for 3 min before they also assumed the modified supine position (group 3, n=46). Isotonic saline 2,300 ml was given intravenously over 15 min before spinal injection followed by 15 ml/kg over 15,20 min after induction of spinal anaesthesia. If the systolic blood pressure decreased to less than 70% of baseline or to less than 100 mmHg or if there was any complaint of nausea, ephedrine was given in 5 mg boluses intravenously every 2 min. Results: The blood pressure decreased significantly in both groups following spinal injection (P<0.001). Blood pressure variations over time differed significantly between the two groups (P<0.05). However, the incidence of maternal hypotension before delivery was similar in the two groups. The difference was caused by the time to the blood pressure nadir being significantly shorter in group 0 compared with group 3 (9.1±4.5 min vs. 11.7±3.7 min, P<0.01). Similar numbers of patients received rescue with ephedrine before delivery: 35 (67%) in group 0 vs. 26 (57%) in group 3 (NS). The mean total dose of ephedrine before delivery was 10.9 mg in group 0 vs. 9.2 mg in group 3 (NS). There were no differences in neonatal outcome between the two groups. Conclusion: At elective caesarean section, a 3-min delay before supine positioning does not influence the incidence of maternal hypotension after induction of spinal anaesthesia in the sitting position with 2.8 ml of bupivacaine 0.5% with 8% dextrose. [source] Immediate outcome of twin,twin transfusion syndrome following selective laser photocoagulation of communicating vessels at the NSW Fetal Therapy CentreAUSTRALIAN AND NEW ZEALAND JOURNAL OF OBSTETRICS AND GYNAECOLOGY, Issue 2 2010N. MERIKI Objective:, To audit the outcome for laser photocoagulation for twin,twin transfusion syndrome (TTTS) as managed by the New South Wales Fetal Therapy Centre (NSW FTC). Methods: A retrospective cohort study. Outcome data were reviewed for referrals between June 2003 and June 2008. The outcome measures included the severity of TTTS at presentation, delivery details (gestational age at delivery, birth weight and Apgar score at 5 min) and perinatal outcome (spontaneous miscarriage, premature rupture of membranes, intrauterine death, placental abruption and neonatal death). Results: Seventy-nine patients were treated with laser therapy for stage I,IV TTTS (median stage III). Median gestational age at treatment was 20 weeks (range 16,25). Median gestational age at delivery was 32 weeks (range 24,40). Survival of at least one baby in this study was 90.7% (88.9% for anterior and 92.1% for posterior placenta), and of both babies was 60.0%. Median birth weight was 1788 g (range 490,3695). Median Apgar score was nine at 5 min. Three women required repeat laser treatment for persistent TTTS. Conclusions: Selective laser photocoagulation of communicating vessels remains the treatment of choice for TTTS. Referrals to the NSW FTC have increased from five cases in the last half of 2003, to 18 cases in the first half of 2008. Local outcome figures at least equal any in the published international literature and support a continued policy of centralised care in Australia. A two-year follow-up study on neonatal outcome for survivors is underway. [source] Fetal extrasystole may predict poor neonatal outcomeAUSTRALIAN AND NEW ZEALAND JOURNAL OF OBSTETRICS AND GYNAECOLOGY, Issue 4 2009Jake A. BROWN Extrasystoles particularly premature atrial contractions noted during labour on the fetal heart rate monitoring strip are usually thought to be benign. In pregnancies complicated by fetal infection and/or the fetal inflammatory response syndrome, there are some data that extrasystoles noted during the intrapartum period may be related to neonatal sepsis and eventual poor neonatal outcome including death or neonatal encephalopathy. Additional observations are needed to substantiate this hypothesis. [source] Effects of Oral L-Arginine on the Foetal Condition and Neonatal Outcome in Preeclampsia: A Preliminary ReportBASIC AND CLINICAL PHARMACOLOGY & TOXICOLOGY, Issue 2 2006Krzysztof Rytlewski Randomized, placebo-controlled, double-blind, clinical trial. Oral therapy with 3 g of L-arginine daily or placebo as a supplement to standard therapy. Eighty-three preeclamptic women, randomly assigned to the L-arginine (n=42) or placebo (n=41) groups; [n=30 (L-arginine) and n=31 (placebo) ended the study, respectively]. Foetal gain chances due to ultrasound biometry, biophysical profile, Doppler velocimetry of pulsatility indices of umbilical and middle cerebral arteries, cerebro-placental ratio, as well as differences in duration of pregnancy and clinical data of newborn. L-arginine treatment transitory accelerated foetal gain and improved biophysical profile. Starting from 3rd week of therapy, the umbilical artery pulsatility indices values were significantly lower in L-arginine than in placebo group. Moreover, treatment with L-arginine caused significant increase of middle cerebral artery pulsatility indices and cerbro-placental ratio values. Latency was longer in L-arginine group. Neonates delivered in the L-arginine group revealed higher Apgar score. Supplementary treatment with oral L-arginine seems to be promising in improving foetal well-being and neonatal outcome as well as in prolonging pregnancy complicated with preeclampsia. However, these benefits require confirmation in more-powered, larger studies.

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] Review of the first 1502 cases of ECG-ST waveform analysis during labour in a teaching hospitalBJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 10 2007V Doria Objective, To assess the impact of introduction of the STAN monitoring system. Study design, Prospective observational study. Setting, Tertiary referral labour ward, St George's Hospital, London. Population, High-risk term pregnancies. Methods, We report all consecutive cases of intrapartum monitoring using the STAN S 21 fetal heart monitor. Cases with adverse neonatal outcome were evaluated in relation to the ST waveform analysis and cardiotocography (CTG). Main outcome measures, Cord artery metabolic acidosis, neonatal encephalopathy (NNE) and reasons behind cases with poor outcome. Results, Between 2002 and 2005, there were 1502 women monitored by STAN. Based on combined STAN analysis in the 1502 women, action was indicated in 358 women (23.8%), while in 1108 women (73.8%) no action was indicated. Traces were not interpretable in 36 women (2.4%). Of the 836 cases (55.7%) where cord blood gases were available, there were 23 cases (2.8%) of metabolic acidosis and 16 of these (70%) were identified by STAN. Overall, there were 14 cases of NNE monitored by STAN. Retrospective analysis of these highlights human errors, such as poor CTG interpretation, delay in taking appropriate action and not following the guidelines. Conclusions, Our experience suggests the need for more intense training on interpretation of CTG and strict adherence to guidelines.

[source] Fetal activin A: associations with labour, umbilical artery pH and neonatal outcomeBJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 4 2004Stephen Tong Objective To define the ontogeny of umbilical artery activin A at term and to evaluate activin A as a potential marker of perinatal hypoxia. Design A cohort study. Setting A university teaching hospital delivery suite. Population A convenience sample of 141 term pregnancies. Methods At delivery, umbilical artery and vein bloods were collected for blood gas measurements and subsequent measurement of activin A. Activin A levels were correlated with blood gas measurements and with labour and neonatal outcomes. Main outcome measures Umbilical arterial activin A and pH. Results The median (95% CI) umbilical arterial activin A level at delivery was 1.38 (1.34,1.70) ng/mL. Levels varied significantly across gestation (P= 0.03), increasing from 36 to 38 weeks, thereafter decreasing to a nadir at 41 weeks. In 60 matched samples, the median (95% CI) venous and arterial activin A levels were 0.89 (0.81,1.06) ng/mL and 1.38 (1.21,1.61) ng/mL, respectively (P < 0.0001). Mean umbilical arterial pH was 7.20 (7.06,7.38; 5,95th centiles) and was not significantly correlated with log10 activin A (r=, 0.01; P= 0.68). Compared with healthy controls, there was no difference in arterial activin A in neonates identified as having suffered significant intrapartum asphyxia (P= 0.96). Fetal activin A levels were significantly lower in cases delivered by emergency caesarean section for complications during the first stage of labour compared with cases delivered vaginally (P= 0.003). Conclusions Umbilical artery activin A does not appear to be a sensitive marker of fetal oxygenation or of risk of hypoxic,ischaemic encephalopathy. [source] The case for tocolysis in threatened preterm labourBJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 2003Nicholas M. Fisk The failure of tocolytics to improve neonatal outcomes in placebo-controlled trials has wrongly been interpreted as evidence that they do not work. While delivery is unequivocally prolonged by 24 hours, 48 hours and 7 days, the time gained was not exploited to optimise neonatal outcome. These trials typically studied women at relatively advanced gestational ages with predictably good outcomes, enrolled them in tertiary centres where they could not benefit from in-utero transfer, and had low levels of corticosteroid administration. No study has been powered to detect clinically meaningful differences that might be expected to accrue from 1,7 days prolongation of gestation. Despite this, Bayesian interpretation suggests that tocolytics do improve neonatal outcome. The largest placebo-controlled study showed clear trends towards better survival in fetuses <28 weeks, lower rates of cerebral palsy and higher Bayley mental scores. Meta-analysis of neonatal morbidity in the beta-agonist trials suggests a near-significant reduction in respiratory distress syndrome (RDS), together with trends towards reduced intraventricular haemorrhage, necrotising enterocolitis, and patent ductus arteriosus. Finally, there is the Orwellian analogy that tocolytics don't work, but some work better than others. Although calcium antagonists have not been evaluated against placebo, meta-analysis of comparative trials with beta-agonists demonstrate a significantly lower incidence of RDS and neonatal jaundice, presumably mediated through the reduced chance of delivery within 48 hours and 7 days. Development of tocolytics that are safe for mother and baby should facilitate adequately-powered placebo-controlled studies, which both focus on women most likely to benefit and capitalise on the 1,7 days gained. [source] Unexpected reduction in the incidence of birth trauma and birth asphyxia related to instrumental deliveries during the study period: was this the Hawthorne effect?BJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 3 2003W.C. Leung Objective The study was originally designed to identify the risk factors that could predict those difficult instrumental deliveries resulting in birth trauma and birth asphyxia. Design A prospective study on all singleton deliveries in cephalic presentation with an attempt of instrumental delivery over a 12-month period (13 March 2000 to 12 March 2001). Setting A local teaching hospital. Sample Six hundred and seventy deliveries. Methods A codesheet was designed to record the demographic data, characteristics of first and second stages of labour and neonatal outcome. In particular, the doctor had to enter the pelvic examination findings before the attempt of instrumental delivery. Main outcome measures Birth trauma and birth asphyxia. Results There was a significant reduction in the incidence of birth trauma and birth asphyxia related to instrumental deliveries during the study period (0.6%) when compared with that (2.8%) in the pre-study period (1998 and 1999) (RR 0.27, 95% CI 0.11,0.70). There was more trial of instrumental deliveries in the operating theatre although this was not statistically significant (RR 1.19, 95% CI 0.88,1.60). The instrumental delivery rate decreased during the study period (RR 0.88, 95% CI 0.82,0.94). The caesarean section rate for no progress of labour, the incidence of direct second stage caesarean section and the incidence of failed instrumental delivery did not increase during the study period. Conclusions Apart from the merits of regular audit exercise and increasing experience of the staff, the Hawthorne effect might be the major contributing factor in the reduction of birth trauma and birth asphyxia related to instrumental deliveries during the study period. [source] Expectant management of early onset, severe pre-eclampsia: perinatal outcomeBJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 10 2000D. R. Hall Consultant Objective To evaluate the perinatal outcome of expectant management of early onset, severe pre-eclampsia. Design Prospective case series extending over a five-year period. Setting Tertiary referral centre. Population All women (n= 340) presenting with early onset, severe pre-eclampsia, where both mother and the fetus were otherwise stable. Methods Frequent clinical and biochemical monitoring of maternal status with careful blood pressure control. Fetal surveillance included six-hourly heart rate monitoring, weekly Doppler and ultrasound evaluation of the fetus every two weeks. All examinations were carried out in a high care obstetric ward. Main outcome measures Prolongation of gestation, perinatal mortality rate, neonatal survival and major complications. Results A mean of 11 days were gained by expectant management. The perinatal mortality rate was 24/1000 (, 1000 g/7 days) with a neonatal survival rate of 94%. Multivariate analysis showed only gestational age at delivery to be significantly associated with neonatal outcome. Chief contributors to neonatal mortality and morbidity were pulmonary complications and sepsis. Three pregnancies (0.8%) were terminated prior to viability and only two (0.5%) intrauterine deaths occurred, both due to placental abruption. Most women (81.5%) were delivered by caesarean section with fetal distress the most common reason for delivery. Neonatal intensive care was necessary in 40.7% of cases, with these babies staying a median of six days in intensive care. Conclusion Expectant management of early onset, severe pre-eclampsia and careful neonatal care led to high perinatal and neonatal survival rates. It also allowed the judicious use of neonatal intensive care facilities. Neonatal sepsis remains a cause for concern. [source] Labour characteristics and uterine activity: misoprostol compared with oxytocin in women at term with prelabour rupture of the membranesBJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 2 2000Suk Wai Ngai Assistant Professor Objective To compare the labour pattern and uterine activity of oral misoprostol with oxytocin for labour induction in women presenting with prelabour rupture of membranes at term. Design Prospective randomised study. Setting Department of Obstetrics and Gynaecology, Queen Mary Hospital, Hong Kong. Participants Eighty women presenting with prelabour rupture of membranes at term. Methods The women were randomised to receive either 100 ,g misoprostol orally every 4 hours to a maximum of three doses, or intravenous oxytocin infusion according to the hospital protocol. Intrauterine pressure transducers were inserted one hour before induction of labour in both groups of women. We compared the pattern of uterine activity, the induction-to-delivery interval, duration of labour, mode of delivery and neonatal outcome between the two groups. Results Both oxytocin and oral misoprostol caused an increase in uterine activity within one hour of labour induction. Peak uterine activity was reached 6,8 h after oral misoprostol, with persistent effects, and 8,10 h after oxytocin, requiring continuous titration of medication. The duration of labour was significantly reduced in nulliparous women, but not in those who were multiparous in the misoprostol group. The induction-to-delivery interval, the mode of delivery and the perinatal outcome were similar for the two groups. Conclusion Oral misoprostol caused earlier peak uterine activity, compared with oxytocin (6,8 h vs 8,10 h). Oral misoprostol was not only as effective as oxytocin in inducing labour in women at term with prelabour rupture of the membranes, but it reduced significantly the duration of labour in nulliparous women. [source] Neonatal intensive care utilization and neonatal outcome of infants born to women aged 40 years and over in New ZealandACTA PAEDIATRICA, Issue 2 2010M Battin Abstract Background:, Increased maternal age is associated with pregnancy complications and there are few data available on neonatal outcome and utilization of neonatal resources. Our first aim was to use national New Zealand data to determine if the outcomes following admission to NICU are different for infants born to women aged 40 years and over, compared with those born to women under 40 years of age. The second aim was to document trends in the requirement of neonatal intensive care in infants born to women aged 40 years and older. Method:, Eligible infants were identified from registration with the Australian and New Zealand Neonatal Network for 1995,2004 inclusive. The relationship between maternal age and neonatal outcome was tested using univariate and multivariate analysis, and trends in the number of infants in maternal age groups below 35 years, 35,39 years and over 40 years were determined. Results:, On multivariate analysis using logistic regression, maternal age over 40 years was not found to be associated with a significant increase in the odds ratio for the composite poor outcome. However, over the 10-year period, there was an increase in the number of admissions and the percentage of admissions of infants born to women over 40 years of age. Conclusion:, Although the number of infants admitted for neonatal care following birth to women over 40 years of age has increased, these infants do not appear to have an increased risk of severe abnormal outcome. [source] Remifentanil for INSURE in preterm infants: a pilot study for evaluation of efficacy and safety aspectsACTA PAEDIATRICA, Issue 9 2009L Welzing Abstract Aim:, To evaluate intubating conditions, extubation times and outcome in preterm infants receiving remifentanil as induction agent for the INSURE procedure. Methods:, In twenty-one preterm infants of 29 to 32 weeks gestation and signs of respiratory distress, we utilized remifentanil as induction agent for the INSURE procedure. Following intubation and surfactant application, the infants were mechanically ventilated until respiratory drive was judged to be satisfactory for continuing CPAP therapy. Intubating conditions were classified by our own scoring system by rating limb movements, coughing and breathing. Heart rate, blood pressure and oxygen saturation were recorded during the entire INSURE procedure. Results:, Remifentanil provided excellent or good intubating conditions in all patients. We observed no serious side effects after remifentanil infusion, in particular, no thorax rigidity, clinically significant bradycardia or arterial hypotension. Average extubation time after surfactant administration was 16.9 min (1,45 min); none of the infants had to be reintubated. Following extubation, the infants required only 3.3 days (1,8 days) of CPAP therapy. None exhibited serious complications of prematurity like periventricular leucomalacia, intraventricular haemorrhage >I°, necrotizing enterocolitis or retinopathy. Conclusion:, In this pilot study, INSURE with remifentanil was associated with good intubating conditions and early extubation resulting in an excellent neonatal outcome. [source] |
