Abstract
BACKGROUND Antenatal day care units have been widely used as an alternative to inpatient care for women with pregnancy complications including mild and moderate hypertension, and preterm prelabour rupture of the membranes. OBJECTIVES The objective of this review is to compare day care units with routine care or hospital admission for women with pregnancy complications in terms of maternal and perinatal outcomes, length of hospital stay, acceptability, and costs to women and health services providers. SEARCH STRATEGY We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (February 2009). SELECTION CRITERIA Randomised controlled trials comparing day care with inpatient or routine care for women with complicated pregnancy. DATA COLLECTION AND ANALYSIS Two review authors independently carried out data extraction and assessed studies for risk of bias. MAIN RESULTS Three trials with a total of 504 women were included. For most outcomes it was not possible to pool results from trials in meta-analyses as outcomes were measured in different ways.Compared with women in the ward/routine care group, women attending day care units were less likely to be admitted to hospital overnight (risk ratio 0.46, 95% confidence interval 0.34 to 0.62). The average length of antenatal admission was shorter for women attending for day care, although outpatient attendances were increased for this group. There was evidence from one study that women attending for day care were significantly less likely to undergo induction of labour, but mode of birth was similar for women in both groups. For other outcomes there were no significant differences between groups.The evidence regarding the costs of different types of care was mixed; while the length of antenatal hospital stays were reduced, this did not necessarily translate into reduced health service costs.While most women tended to be satisfied with whatever care they received, women preferred day care compared with hospital admission. AUTHORS' CONCLUSIONS Small studies suggest that there are no major differences in clinical outcomes for mothers or babies between antenatal day units or hospital admission, but women may prefer day care.

Abstract
OBJECTIVE Fetal lung maturity (FLM) studies using vaginal pool can guide management in near-term gestations with rupture of membranes. Because an adequate sample may be difficult to collect using a syringe, we tested collection using a sterile sponge. STUDY DESIGN In this prospective study, vaginal pool was collected via both a syringe and a sponge from each gravida. Study patients experienced rupture of membranes between 34-41 weeks of gestation. Each sample was analyzed using the TDx-FLM II assay and phosphatidylglycerol (PG) testing. RESULTS Fifty patients were enrolled; 44 demonstrated concordant syringe/sponge results. There was 1 instance of mature TDx-FLM testing using a sponge but not a syringe; PG testing in this case was absent in both samples. Using the kappa statistic, agreement between the methods was "substantial" for TDx-FLM and "almost perfect" for PG. CONCLUSION Collecting vaginal pool with a sponge may provide clinically useful information, particularly when PG is present.

Abstract
Our understanding of the pathophysiologic processes leading to preterm premature rupture of membranes (PPROM) has grown tremendously in recent years. Evidence suggests that there may be a genetic susceptibility to PPROM and that genetic and environmental elements are important cofactors in its development. A number of risk-based protocols have been proposed in an attempt to identify those women at highest risk for PPROM. While we have made advances in the area of predicting PPROM, treatments based on current risk-based systems have failed to distinguish a specific, effective preventive therapy for PPROM. The concept that genetic factors increase susceptibility or decrease resistance to disease has stimulated new work in the field of PPROM. Several maternal and fetal gene polymorphisms have been identified that are associated with an increased risk for PPROM. Patients with 'susceptible' genotypes may also have clinical risk factors for PPROM resulting in a synergistic increase in the risk for PPROM, a so-called gene-environment interaction. The concept that these gene-environment interactions represent new targets for our efforts to prevent PPROM is explored.

Abstract
OBJECTIVE The aim of this randomized trial was to compare the efficacy and safety of vaginal misoprostol and oxytocin for cervical ripening and labor induction in patients with premature rupture of membrane (PROM) at term. METHODS Ninety-seven women with PROM at term were assigned randomly to receive intravaginal misoprostol or oxytocin. The primary outcome measure was the induction-delivery interval. Secondary outcomes included the number of women who delivered vaginally within 12 hours of the start of the induction in the two groups, the cesarean, hyperstimulation, and failed induction rates, the mode of delivery, and the neonatal outcome. RESULTS Forty-eight women were assigned to intravaginal misoprostol and 49 to oxytocin administration. The mean interval from induction to delivery was 10.61 +/- 2.45 hours in the misoprostol group and 11.57 +/- 1.91 hours in the oxytocin group (p = 0.063). The rates of vaginal delivery were 83.3% and 87.7% and cesarean delivery were 16.7% and 8.2% in the misoprostol and oxytocin groups, respectively. Neonatal outcomes were not significantly different. Of the cases, 8.3% in the misoprostol group and 8.2% in the oxytocin group revealed uterine contraction abnormalities. CONCLUSION Our study demonstrates that, intravaginally, misoprostol results in a similar interval from induction of labor to delivery when compared to oxytocin.

Abstract
New knowledge of the pathophysiology of premature birth enables us to introduce new approaches in prenatal care as well as the management of premature delivery. These apply for the patients with subclinical risk factors, particularly with thrombophilias, chronic infections or other latent chronic infections. The peri- and pre-conceptional dispensarisation of these women might help reduce the development of premature delivery. Secondary prevention with the administration of gestagens is highly important for women with anamnestic or existing risk of premature delivery. During the underlying premature delivery, it is advisable to re-evaluate the significance of the administration of antibiotics and tocolytics as well as timing of corticoid dosage in the induction of foetal lung maturity. Using new diagnostic and therapeutic methods, the aim of present premature delivery management is to prolong the duration of pregnancy to the maximum with the lowest risk of the development of foetal inflammatory response possible and, therefore, with a low risk of long-term handicaps in children.

Abstract
Intra-amniotic infection (IAI), or chorioamnionitis, complicates up to 10% of all pregnancies and up to 2% of labors at term. There is a significant risk of complications for the mother and the neonate following IAI, including sepsis and pneumonia. In addition, there is a correlation between IAI and premature rupture of membranes, preterm premature rupture of membranes, preterm labor, and preterm birth. Research in the last decade has also revealed a complex and significant association between IAI and cerebral palsy and other central nervous system damage in both the preterm and term fetus. Timely diagnosis and treatment of IAI can significantly reduce the risk of both maternal and neonatal complications.

Abstract
We present intentional delayed delivery of twin 2 after a spontaneous membrane rupture and abortion oftwin1 in a dichorionic twin pregnancy at 14 weeks. As signs of infection were missing, we adopted a conservative (not expectant) management. The pregnancy was prolonged to 35 weeks' gestation. In the absence of additional risk factors, the role of conservative management of multiple pregnancies after loss of one fetus in prolonging the pregnancy to fetal viability in resource-poor setting is highlighted. The gained gestational age of 20 weeks and 4 days (144 days in all), for the remaining fetus and the healthy mother and child pair after delivery at 35 weeks are discussed. The perinatal, economic and psychological implications are highlighted. The importance of good clinical assessment in the diagnosis of cervical incompetence and using ultrasound scan as a complimentary instrument is emphasized.

Abstract
The obstetrician's role is to recognize and treat maternal systemic infections which may spread transplacentally to the fetus, and to ensure that the lower genital tract is kept free from pathogenic organisms, particularly during the last trimester of pregnancy. In some cases the obstetrician can reduce the likelihood of premature rupture of the membranes by inserting a cervical suture. Where this has not been possible conservative management should be used to keep the fetus in utero before the 34th week and more active after this time. In trapartum infections can be reduced to a minimum by keeping the membranes intact during early labour, by the aggressive use of uterine stimulants to avoid prolonged labour, by exerting extreme care to avoid sepsis during pelvic examinations and internal monitoring, and by earlier use of Caesarean section.

Abstract
BACKGROUND Prematurity is the leading cause of perinatal morbidity and mortality in developed as well as in underdeveloped countries. In one third of the patients with preterm labour there is associated premature rupture of membranes. This prospective observational study was carried out in Ayub Teaching Hospital to determine the prevalence of preterm premature rupture of membrane (PPROM) and its association with the demographic risk factors and its outcome. METHOD There were 889 deliveries in Gynaecology 'C' unit from September 2005 to March 2006. Out of these, 85 patients were confirmed to have PPROM. Detail history and examination along with the demographic risk factors were recorded on a performa. Every patient was followed till her delivery and the mode of delivery and maternal and foetal outcome was recorded. RESULT Prevalence of PPROM in this study was 16%. It was seen to be common among patients who were young (15-25 years) 58.8%, with low socioeconomic status (68.2%), and with an educational status of primary to middle (71.7%). Risk of PPROM was seen to be highest among patients giving birth to their first child (42.2%), with gestational age between 30-35 weeks (43.5% cases) and 35-37 weeks (35.2%). In 69.4% cases there was no previous history of preterm deliveries while in 30.6% cases, there were one, two, or more previous preterm deliveries. Normal vaginal delivery occurred in (65.86%), while instrumental delivery rate in PPROM was 20% and caesarean section rate was 14%. Postnatally 16.47% patients developed infection while 24 (28.2%) babies developed infection and required antibiotics. Majority of babies born to patients with PPROM were low birth weight (62.3%), and 30.5% babies required neonatal intensive care. Perinatal mortality rate was 129.9/1000 (13%) of total births. CONCLUSION PPROM is an important cause of preterm birth, resulting in large number of babies with low birth weight, requiring neonatal intensive care. It is associated with increased foetal morbidity and mortality. Demographic variables can be applied to develop risk scoring so as to identify high-risk cases and treating them in time to prevent ascending infection along with its complications.

OBJECTIVES To assess the effect of fetoscopic tracheal occlusion (FETO) enhanced by hyperoncotic distension on pulmonary hypoplasia from preterm premature rupture of membranes prior to 22 weeks of gestation (ePPROM). METHODS AND RESULTS In a fetus with ePPROM since 19+5 weeks of gestation, MRI at 28+2 weeks provided a lung volume of 10 ml. FETO enhanced by hyperoncotic distension was performed at 28+3 weeks. After 4-5 days, balloon dislodgement was observed. The lung volume increased to 18 ml. The baby was born at 32+4 weeks and survived to discharge. CONCLUSIONS FETO enhanced by hyperoncotic distension may result in impressive lung distension in fetuses with pulmonary hypoplasia from ePPROM. Further research into the life saving potential of this strategy for this common and tragic gestational event is desired.

Abstract
BACKGROUND Preterm prelabour rupture of the membranes (PPROM) is an important clinical problem and a dilemma for the gynaecologist. On the one hand, awaiting spontaneous labour increases the probability of infectious disease for both mother and child, whereas on the other hand induction of labour leads to preterm birth with an increase in neonatal morbidity (e.g., respiratory distress syndrome (RDS)) and a possible rise in the number of instrumental deliveries. METHODS/DESIGN We aim to determine the effectiveness and cost-effectiveness of immediate delivery after PPROM in near term gestation compared to expectant management. Pregnant women with preterm prelabour rupture of the membranes at a gestational age from 34+0 weeks until 37+0 weeks will be included in a multicentre prospective randomised controlled trial. We will compare early delivery with expectant monitoring. The primary outcome of this study is neonatal sepsis. Secondary outcome measures are maternal morbidity (chorioamnionitis, puerperal sepsis) and neonatal disease, instrumental delivery rate, maternal quality of life, maternal preferences and costs. We anticipate that a reduction of neonatal infection from 7.5% to 2.5% after induction will outweigh an increase in RDS and additional costs due to admission of the child due to prematurity. Under these assumptions, we aim to randomly allocate 520 women to two groups of 260 women each. Analysis will be by intention to treat. Additionally a cost-effectiveness analysis will be performed to evaluate if the cost related to early delivery will outweigh those of expectant management. Long term outcomes will be evaluated using modelling. DISCUSSION This trial will provide evidence as to whether induction of labour after preterm prelabour rupture of membranes is an effective and cost-effective strategy to reduce the risk of neonatal sepsis.

Abstract
This study aims at evaluating the outcome of pregnancies complicated by pre-term premature rupture of membrane (PPROM) in a developing country and to highlight the problems of managing such cases and ways of improving future management. This was a retrospective review of 344 patients with PPROM at a University of Nigeria Teaching Hospital Enugu, Nigeria over a 10-year period (January 1994-December 2003). The prevalence of PPROM in this study was 25 per 1,000 births and patients of low parity (para 0-2) accounted for the highest number (56.4%). Previous abortion was significantly more among these women of low parity and may be a factor in the aetiology of PPROM. The gestational age range 28-30 weeks recorded the highest incidence (29.7%) of PPROM. The most common associated aetiological factor was cervical incompetence (11.6%), while chorioamnionitis, a major complication in the patients showed a statistically significant reduction with early antibiotic administration (p<0.05). About 72% (n=248) of the patients arrived at the hospital within 24 h of membrane rupture. Perinatal mortality was high (520 per 1,000 births) due to prematurity and perinatal infections. Better fetal outcomes were recorded among patients with PPROM at gestational age above 30 weeks, fetal weight above 2 kg, normal delivery, absence of maternal infection and latent period of not more than 5 days (p<0.05). The parity of the women did not significantly affect fetal outcome (p>0.05). Two (0.6%) maternal deaths were recorded. Prompt patient referral, early institution of antibiotics and improvement of neonatal facilities in tertiary health institutions in developing countries is advocated as a way of improving fetal survival in PPROM.

Abstract
OBJECTIVE To review the indications and outcomes of pregnant women requiring emergency air transfer to the Women's Hospital, IWK Health Centre, Halifax, Nova Scotia. METHODS A two-year (2003 and 2004) review of all antenatal and intrapartum air transfers to the Women's Hospital, IWK Health Centre, Halifax, via the Nova Scotia Department of Health Emergency Health Services (EHS) LifeFlight Program. Charts were reviewed for indications for maternal transfer and perinatal outcomes. RESULTS There were 121 maternal air transfers, representing 1.3% of all deliveries at the Women's Hospital. The primary reasons for transfer were threatened preterm labour (PTL) (41%); preterm premature rupture of the membranes (PPROM) (21%); hypertensive disease/hemolysis, elevated liver enzymes, and low platelets (HELLP) (16.5%); antepartum hemorrhage (13%); and others (8.5%). Of the women transferred, 63% delivered at the Women's Hospital, and 37% returned for delivery to their home hospital. Women transferred for threatened PTL were significantly less likely than those transferred for all other reasons to need delivery at the Women's Hospital (RR 0.44 [0.30-0.65], P < 0.0001). CONCLUSION In almost two thirds of cases, the indications for emergency air transport of pregnant women are threatened PTL or PPROM. The application of fetal fibronectin testing in cases of suspected PTL has the potential to reduce the need for maternal air transfer.

Abstract
Preterm delivery occurs in approximately 12% of all births in the United States and is a major factor contributing to perinatal morbidity and mortality (1, 2). Despite extensive research in this area, the rate of preterm birth has increased by 38% since 1981 (3). Premature rupture of membranes (PROM) is a complication in approximately one third of preterm births. It typically is associated with brief latency between membrane rupture and delivery, increased potential for perinatal infection, and in utero umbilical cord compression. Because of this, both PROM at and before term can lead to significant perinatal morbidity and mortality. There is some controversy over the optimal approaches to clinical assessment and treatment of women with term and preterm PROM. Management hinges on knowledge of gestational age and evaluation of the relative risks of preterm birth versus intrauterine infection, abruptio placentae, and cord accident that could occur with expectant management. The purpose of this document is to review the current understanding of this condition and to provide management guidelines that have been validated by appropriately conducted outcome-based research. Additional guidelines on the basis of consensus and expert opinion also are presented.

Abstract
OBJECTIVES The aim of our study was to define the benefits and risks related to expectant management in the midtrimester rupture of membranes and to assess the prognostic factors in order to give objective informations to parents facing these obstetrical situations. STUDY DESIGN We conducted a retrospective study. The study population included 49 patients with premature rupture of membranes at 16-23 weeks' gestation during the period January 1998-June 2003. The main criterion for judgement was neonate survival. Statistical analysis included chi2-test for the qualitative variables and Student's test for the quantitative variables. The threshold for significance was 5%. RESULTS Twenty couples out of 49 chose medical termination of pregnancy. Among the 29 other pregnancies, the mean latency period was 2.1 weeks. The mean gestational age at delivery was 23.2 weeks. Nineteen patients were delivered after 22 weeks. The main prognostic factors were the initial amniotic fluid index (2.9 cm versus 0.8 cm) (p=0.042) and gestational age at delivery (26.7 weeks versus 22.6 weeks) (p<0.001). About 2% of the pregnancies were complicated by maternal infection. Eighty-three percent of the survivors had neonatal respiratory distress syndrome. 41.2% of them presented sepsis. We observed no cases of severe intraventricular haemorrhage. The number of infants born after 24 weeks of gestation and still alive at 1 week was 12, representing 24% of pregnancies and 63% of the infants born after 24 weeks. CONCLUSION Expectant management can be widely suggested to patients. However, termination of pregnancy is acceptable, in cases with a poor prognosis including anamnios and premature rupture of membranes before 21 weeks.

Eur J Obstet Gynecol Reprod Biol 2007; 131:40-44. [PMID: 16730113 DOI: 10.1016/j.ejogrb.2006.04.024] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2005] [Revised: 03/24/2006] [Accepted: 04/20/2006] [Indexed: 11/30/2022]
Abstract
OBJECTIVES To investigate the effect of transcervical amnioinfusion on the management of labour and neonatal outcomes in preterm premature rupture of the membranes. STUDY DESIGN This clinical trial included 86 patients with premature rupture of the membranes between weeks 27 and 35 of gestation. Patients were randomly assigned to receive amnioinfusion via a two-way catheter or to the control group. Clinical management was otherwise the same in both groups. RESULTS Amnioinfusion decreased the frequency of variable decelerations in fetal heart rate (27.9% versus 53.5%, p<0.05) and the rate of obstetric interventions motivated by nonreassuring fetal status (13.6% versus 52.4%, p<0.05). At delivery, pH values were significantly higher in the treatment group than in the conventionally managed control group (median 7.29 versus 7.27). CONCLUSIONS Intrapartum transcervical amnioinfusion for preterm premature rupture of the membranes reduced the number of interventions needed because of nonreassuring fetal status, and improved neonatal gasometric values without increasing maternal or fetal morbidity.
