Abstract
OBJECTIVE Periviable premature rupture of membranes (PROM) counseling should describe maternal and neonatal outcomes associated with both immediate delivery and expectant management. Unfortunately, most published data focuses on neonatal outcomes and maternal risk estimates vary widely. We performed a meta-analysis to describe outcomes associated with expectant management compared with immediate delivery of periviable PROM. STUDY DESIGN We performed a search on PubMed, MEDLINE, Web of Science, PROSPERO, Cochrane library, and ClinicalTrials.gov utilizing a combination of key terms. Published clinical trials and observational cohorts were included if published after 2000. Publications were selected if they included maternal and/or neonatal outcomes for both expectant management and immediate delivery. Gestational age range was limited from 14 to 25 weeks. The primary outcome was maternal sepsis. Secondary outcomes included chorioamnionitis, hemorrhage, laparotomy, and neonatal survival. Pooled risk differences (RDs) were calculated for each outcome using a random-effects model. Publication bias was assessed using funnel plots and Harbord test. RESULTS A total of 2,550 studies were screened. After removal of duplicates and filtering by abstract, 44 manuscripts were reviewed. A total of five publications met inclusion for analysis: four retrospective and one prospective. Overall, 364 (68.0%) women underwent expectant management and 171 (32.0%) underwent immediate delivery. Maternal sepsis was significantly more frequent in the expectant group (RD, 4%; 95% confidence interval, 2-7%) as was chorioamnionitis (RD 30%; p < 0.01) and any laparotomy (RD, 28%; p < 0.01). Neonatal survival in the expectant group was 39% compared with 0% in the immediate group (p < 0.01). CONCLUSION Women who undergo expectant management following periviable rupture of membranes experience significantly increased risks of sepsis, chorioamnionitis, and laparotomy. Overall, 39% of neonates survive to discharge. Knowledge of these risks is critical to counseling patients with this diagnosis. KEY POINTS · Expectant management associated with 4% increased risk of sepsis.. · Expectant management associated with 30% increased risk of chorioamnionitis.. · A total of 39% of neonates survived to discharge with expectant management..

Abstract
Objective To describe perinatal and maternal outcomes of preterm prelabour rupture of membranes (PPROM) before 23 weeks' gestation in a national cohort. Design Prospective observational study. Setting National population based cohort study with the UK Obstetric Surveillance System (UKOSS), a research infrastructure of all 194 obstetric units in the UK, 1 September 2019 to 28 February 2021. Participants 326 women with singleton and 38 with multiple pregnancies with PPROM between 16+0 and 22+6 weeks+days' gestation. Main outcome measures Perinatal outcomes of live birth, survival to discharge from hospital, and severe morbidity, defined as intraventricular haemorrhage grade 3 or 4, or requiring supplemental oxygen at 36 weeks' postmenstrual age, or both. Maternal outcomes were surgery for removal of the placenta, sepsis, admission to an intensive treatment unit, and death. Clinical data included rates of termination of pregnancy for medical reasons. Results Perinatal outcomes were calculated with all terminations of pregnancy for medical reasons excluded, and a worst-best range was calculated assuming that all terminations for medical reasons and those with missing data would have died (minimum value) or all would be liveborn (maximum value). For singleton pregnancies, the live birth rate was 44% (98/223), range 30-62% (98/326-201/326), perinatal survival to discharge from hospital was 26% (54/207), range 17-53% (54/326-173/326), and 18% (38/207), range 12-48% (38/326-157/326) of babies survived without severe morbidity. The rate of maternal sepsis was 12% (39/326) in singleton and 29% (11/38) in multiple pregnancies (P=0.004). Surgery for removal of the placenta was needed in 20% (65/326) and 16% (6/38) of singleton and twin pregnancies, respectively. Five women became severely unwell with sepsis; two died and another three required care in the intensive treatment unit. Conclusions In this study, 26% of women who had very early PPROM with expectant management had babies that survived to discharge from hospital. Morbidity and mortality rates were high for both mothers and neonates. Maternal sepsis is a considerable risk that needs more research. These data should be used in counselling families with PPROM before 23 weeks' gestation, and currently available guidelines should be updated accordingly.

Abstract
Importance Periviable and previable premature rupture of membranes (pPPROM) occurs in <1% of pregnancies but can have devastating consequences for the mother and the fetus. Understanding risk factors, possible interventions, and both maternal and neonatal outcomes will improve the counseling and care provided for these patients. Objective The aim of this review is to describe the etiology, risk factors, management strategies, neonatal and maternal outcomes, and recurrence risk for patients experiencing pPPROM. Evidence Acquisition A PubMed, Web of Science, and CINAHL search was undertaken with unlimited years searched. The search terms used included "previable" OR "periviable" AND "fetal membranes" OR "premature rupture" OR "PROM" OR "PPROM." The search was limited to English language. Results There were 181 articles identified, with 41 being the basis of review. Multiple risk factors for pPPROM have been identified, but their predictive value remains low. Interventions that are typically used once the fetus reaches 23 to 24 weeks of gestation have not been shown to improve outcomes when used in the previable and periviable stage. Neonatal outcomes have improved over time, but survival without severe morbidity remains low. Later gestational age at the time of pPPROM and longer latency period have been shown to be associated with improved outcomes. Conclusions and Relevance Periviable and previable premature rupture of membranes are uncommon pregnancy events, but neonatal outcomes remain poor, and routine interventions for PPROM >24 weeks of gestation have not proven beneficial. The 2 most reliable prognostic indicators are gestational age at time of pPPROM and length of the latency period.

CHILDREN (BASEL, SWITZERLAND) 2023; 10:1347. [PMID: 37628346 PMCID: PMC10453507 DOI: 10.3390/children10081347] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/17/2023] [Revised: 07/14/2023] [Accepted: 07/31/2023] [Indexed: 08/27/2023]
Abstract
The diagnosis of previable preterm pre-labor rupture of membranes (PROM) is known to be associated with poor outcomes for both the mother and the fetus. Following previable preterm PROM, patients are generally offered either active management through the termination of the pregnancy or expectant management to increase the chances of fetal survival. It is difficult to counsel patients because there is a lack of data directly comparing maternal outcomes following active vs. expectant management. Using the data in the current literature, the goal of the present meta-analysis was to determine if there were any differences in terms of maternal risks when active versus elective management was chosen. PubMed, Google Scholar, EMBASE, and Scopus were searched. We found four studies accounting for a total of 506 patients. The risk ratio (RR) of chorioamnionitis in active vs. expectant management was 0.30 (with a 95% confidence interval, CI, of 0.09-1.02). The heterogeneity of the study results was 81% (I2). A sub-analysis of two included studies revealed an RR of postpartum hemorrhage in active vs. expectant management of 0.75 (95% CI 0.27-2.07) and an RR of maternal sepsis of 0.23 (95% CI 0.04-1.28). The heterogeneity of the study results for this sub-analysis was 68% (I2) for postpartum hemorrhage and 0% (I2) for maternal sepsis. Overall, there was no statistically significant difference in the risk of chorioamnionitis, postpartum hemorrhage, or maternal sepsis when active management was chosen over expectant management in previable preterm PROM at <24 weeks. The scarcity and the high heterogeneity of the available data likely contributed to the lack of statistical significance and calls for further work directly comparing maternal outcomes following active vs. expectant management.

Abstract
Preterm prelabour rupture of membranes (PPROMs) before viability carries significant perinatal mortality and morbidity. Clinical management and prenatal counselling are a challenge, especially in twin pregnancies, due to scarce evidence on how previable PPROM affects this population. The aim of this study was to describe pregnancy outcomes of twin pregnancies complicated with previable PPROM and evaluate potential prognostic factors that may predict perinatal mortality. A retrospective cohort including dichorionic and monochorionic diamniotic twin pregnancies complicated with PPROM before 24 + 0 weeks of pregnancy was evaluated. Perinatal outcomes of pregnancies managed expectantly were described. Factors predicting perinatal mortality or reaching periviability (defined from 23 + 0 weeks onwards) were evaluated. Of the 45 patients included, 7 (15.6%) spontaneously delivered within the first 24 h after diagnosis. Two patients (5.3%) requested selective termination of the affected twin. In the 36 ongoing pregnancies that opted for expectant management, the overall survival rate was 35/72 (48.6%). There were 25/36 (69.4%) patients who delivered after 23 + 0 weeks of pregnancy. When periviability was achieved, neonatal survival increased up to 35/44 (79.5%). Gestational age at delivery was the only independent risk factor of perinatal mortality. The overall survival rate of twin pregnancies complicated with previable PPROM is poor but similar to singletons. No prognostic factors, apart from achieving periviability, were identified as individual predictors of perinatal mortality.

Abstract
BACKGROUND ppPROM < 24 + 0 weeks of gestation complicates < 1 % of all pregnancies but is responsible for significant maternal and neonatal morbidity. It is associated with 18-20% of perinatal deaths. OBJECTIVE To evaluate neonatal outcome after expectant management in ppPROM in order to obtain evidence-based information for purposes of future counselling. METHODS A single-centre, retrospective cohort study of 117 neonates born 1994 to 2012 after ppPROM < 24 weeks of gestation with a latency period > 24 hours and admission to the NICU of the Department of Neonatology, University of Bonn. Data of pregnancy characteristics and neonatal outcome were collected. The results were compared to those found in the literature. RESULTS The mean gestational age at ppPROM was 20.45±2,9 weeks (range 11 + 2 -22 + 6) with a mean latency period of 44.7±34.8 days (range 1-135). Mean gestational age at birth was 26.77±3.22 weeks (range 22 + 2-35 + 3). 117 newborns were admitted to the NICU, the overall survival rate at discharge was 72.6% (85/117). Non-survivors had a significantly lower gestational age and higher rates of intra-amniotic infections. The most common neonatal morbidities were RDS (76.1%), BPD (22.2%), pulmonary hypoplasia (PH) (14.5%), neonatal sepsis (37.6%), IVH (34.1% all grades, 17.9% grades III/IV), NEC (8.5%) and musculoskeletal deformities (13.7%). Mild growth restriction as a new complication of ppPROM was observed. CONCLUSIONS Neonatal morbidity after expectant management is similar to that described for infants without ppPROM, but carries a higher risk of pulmonary hypoplasia and mild growth restriction.

[PMID: 36758309 DOI: 10.1016/j.jflm.2023.102491] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2022] [Revised: 01/30/2023] [Accepted: 02/02/2023] [Indexed: 02/05/2023]
Abstract
PURPOSE In the present study, the purpose was to determine the indications of pregnancy termination procedures that are performed before and after the limit of viability (between 10 and 22 weeks) in a tertiary center and to investigate the characteristics of the cases in which fetocide procedure was offered after the limit of viability (22 weeks and later). It also aimed to discuss the legal deadline for the fetocide procedure and legal aspect of pregnancy termination. MATERIAL AND METHOD The present study was conducted as a result of the retrospective examination of 198 cases who underwent pregnancy termination after the 10th week of pregnancy (the legal limit for voluntary termination of pregnancy in our country) in our clinic and met the study criteria. The cases were divided into two main groups as Early Termination (10-22 weeks) and Late Termination (22 weeks and later). The characteristics of these groups (i.e. reason for termination, termination week) and the characteristics of the cases in which fetocide procedure was performed and the cases that were not (i.e. termination week, reasons for termination) were compared. RESULTS A total of 171 (86%) cases were under 22 weeks and 27 (14%) were 22 weeks or more. In the cases terminated early, the gestational week was found to be highest [20 + 1 (12+3-21 + 1)] in those with preterm premature rupture of membranes, and lowest in those with fetal gastrointestinal abnormalities. No statistically significant differences were detected between the termination reason and the gestational week in the late-terminated group, and also, although the termination week of 5 patients for whom the fetocide procedure was offered [median = 23 + 1 (22+4-26 + 0] was higher than the week of 22 patients for whom the fetocide procedure was not offered [median = 22 + 4 (22+1-25 + 4], the difference was not found to be statistically significant. CONCLUSION Since the majority of pregnancy terminations are performed before the viable period, the need for the fetocide procedure in pregnancy terminations is relatively low, and we think that this rate will decrease even more because the rate of early diagnosis of fetal anomalies increases as a result of developments in ultrasonographic imaging. Families who choose the termination of pregnancy search for other countries with appropriate legislation and the loss of time and the indecision of the family might cause the application of pregnancy termination after the viable period because of the limitations in the legal regulations of countries.

Abstract
Objective To describe the early neurodevelopmental outcomes following fetal exposure to previable preterm prelabour rupture of membranes (pPPROM). Methods This was a secondary analysis of a subgroup of neonates born following pPPROM from a retrospective cohort study (2009–2015). Surviving infants who underwent standardized neurodevelopmental evaluation at 18–24 months corrected age (CA) between 2017 and 2019 were eligible for inclusion. Data abstracted from hospital charts were linked to prospectively collected developmental outcomes stored in an electronic database from a regional neonatal follow-up clinic. The primary outcome was Bayley-III composite scores (compared to the population mean 100, standard deviation (SD) 15). Secondary outcomes included presence of cerebral palsy, vision loss, hearing impairment, and requirement of rehabilitation therapy. Descriptive statistics were used to present results. Results 25.7% (19/74) of neonates born after pPPROM survived to hospital discharge, but only 21.6% (16/74) survived to 18–24 months CA. Of these, 9 infants were eligible for follow-up at the regional clinic and 7 had developmental outcomes stored in the electronic database. Infants exposed to pPPROM exhibited Bayley-III scores more than 1 SD below the population mean across all three domains: cognitive 84.9 (SD 12.2); motor 82.3 (SD 11.5); and language 66.4 (SD 18.9). There were particular deficiencies in language development with 71% (5/7) scoring more than 2 SDs below the population mean. There were no cases of cerebral palsy. Conclusions Only 1 in 5 infants born following expectantly managed pPPROM survived to 18–24 months CA. These infants born after pPPROM had significantly lower Bayley-III scores and particular deficiencies in language development. Better understanding of early neurodevelopmental challenges following pPPROM will help refine counselling of families contemplating expectant management and provide insights into the postnatal educational resources required to improve long-term developmental outcomes for these children.

Abstract
BACKGROUND After preterm premature rupture of membranes at <24 weeks' gestation, pregnant women may choose continuation (expectant management) or termination of pregnancy, via either dilation and evacuation or labor induction. Neonatal outcomes after expectant management are well described. In contrast, limited research addresses maternal outcomes associated with expectant management compared to termination of pregnancy. OBJECTIVE This study aimed to compare maternal morbidity after preterm premature rupture of membranes at <24 weeks' gestation in women who choose either expectant management or termination of pregnancy. STUDY DESIGN This retrospective cohort study included women with preterm premature rupture of membranes between 14 0/7 and 23 6/7 weeks' gestation with singleton or twin pregnancies at 3 institutions from 2011 to 2018. We excluded pregnancies complicated by fetal anomalies, rupture of membranes immediately after obstetrical procedures (chorionic villus sampling, amniocentesis, cerclage placement, fetal reduction), spontaneous delivery <24 hours after membrane rupture, and contraindications to expectant management. Our primary outcome was the difference in composite maternal morbidity between women choosing expectant management and women choosing termination of pregnancy. We defined composite maternal morbidity as at least 1 of the following: chorioamnionitis, endometritis, sepsis, unplanned operative procedure after delivery (dilation and curettage, laparoscopy, or laparotomy), injury requiring repair, unplanned hysterectomy, unplanned hysterotomy (excluding cesarean delivery), uterine rupture, hemorrhage of >1000 mL, transfusion, admission to the maternal intensive care unit, acute renal insufficiency, venous thromboembolism, pulmonary embolism, and readmission to the hospital within 6 weeks. We compared the demographic and antenatal characteristics of women choosing expectant management with that of women choosing termination of pregnancy and used logistic regression to quantify the association between initial management decision and composite maternal morbidity. RESULTS We identified 350 women with pregnancies complicated by preterm premature rupture of membranes at <24 weeks' gestation, and 208 women were eligible for the study. Of the 208 women, 108 (51.9%) chose expectant management as initial management, and 100 (48.1%) chose termination of pregnancy as initial management. Among women selecting termination of pregnancy, 67.0% underwent labor induction, and 33.0% underwent dilation and evacuation. Compared to women who chose termination of pregnancy, women who chose expectant management had 4.1 times the odds of developing chorioamnionitis (38.0% vs 13.0%; 95% confidence interval, 2.03-8.26) and 2.44 times the odds of postpartum hemorrhage (23.1% vs 11.0%; 95% confidence interval, 1.13-5.26). Admissions to the intensive care unit and unplanned hysterectomy only occurred after expectant management (2.8% vs 0.0% and 0.9% vs 0.0%). Of women who chose expectant management, 36.2% delivered via cesarean delivery with 56.4% non-low transverse uterine incisions. Composite maternal morbidity rates were 60.2% in the expectant management group and 33.0% in the termination of pregnancy group. After adjusting for gestational age at rupture, site, race and ethnicity, gestational age at entry to prenatal care, preterm premature rupture of membranes in a previous pregnancy, twin pregnancy, smoking, cerclage, and cervical examination at the time of presentation, expectant management was associated with 3.47 times the odds of composite maternal morbidity (95% confidence interval, 1.52-7.93), corresponding to an adjusted relative risk of 1.91 (95% confidence interval, 1.35-2.73). Among women who chose expectant management, 15.7% avoided morbidity and had a neonate who survived to discharge. CONCLUSION Expectant management for preterm premature rupture of membranes at <24 weeks' gestation was associated with a significantly increased risk of maternal morbidity when compared to termination of pregnancy.

Maternal, perinatal and childhood outcomes of the PPROMEXIL-III cohort: Pregnancies complicated by previable prelabor rupture of membranes. Eur J Obstet Gynecol Reprod Biol 2021; 265:44-53. [PMID: 34428686 DOI: 10.1016/j.ejogrb.2021.08.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2021] [Revised: 07/30/2021] [Accepted: 08/03/2021] [Indexed: 10/20/2022]
Abstract
OBJECTIVE Perinatal mortality after previable prelabor rupture of membranes (previable PROM) might be underestimated as most studies exclude patients with poor prognosis, or solely include patients in tertiary-care centers. We aimed to report perinatal, neonatal and long-term outcomes in a consecutive series of women with pregnancies complicated by previable PROM. STUDY DESIGN We conducted a prospective cohort study including women with singleton pregnancies and previable PROM ≤ 23+6 weeks gestational age (GA) from one tertiary hospital and eight affiliated secondary hospitals in the region of Amsterdam, the Netherlands (June 2012 until January 2016, PPROMEXIL-III cohort). Exclusion criteria were signs of active labor before onset of PROM or fetal structural anomalies visible at ultrasound. We assessed perinatal mortality. Furthermore, outcomes were maternal, perinatal, neonatal and long-term child characteristics. RESULTS We included 98 pregnancies with previable PROM. Twelve women (12.2%) opted for termination of pregnancy, resulting in 86 pregnancies included in further analyses. Median GA at PROM was 20+2 weeks (interquartile range (IQR) 17+6-22+0). Median GA at delivery was 22+6 weeks (IQR 20+1-26+4). Delivery within 1 week occurred in 38.4% of women and 60.4% delivered before 24 weeks GA (viability). Perinatal mortality occurred in 73.3% of pregnancies. 23/33 (69.7%) live-born neonates survived to discharge, representing 26.7% of total. None of the children died after discharge. Developmental data at two and/or five years of age was available for 13/23 children (i.e. all children born before 32 weeks of gestation), with 69.2% of children reporting a normal neurodevelopment. However, more than half of children reported respiratory problems. CONCLUSION In women with previable PROM perinatal mortality was 73.3%, with a normal neurodevelopment in 69.2% of surviving children with follow-up data. Due to broad inclusion criteria, this cohort represents a population more generalizable to daily practice as compared to previous studies.

Predicting previable preterm premature rupture of membranes (pPPROM) before 24 weeks: maternal and fetal/neonatal risk factors for survival. J OBSTET GYNAECOL 2021; 42:597-606. [PMID: 34382497 DOI: 10.1080/01443615.2021.1935818] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 10/20/2022]
Abstract
We sought to compare maternal and neonatal risk factors in cases with previable premature rupture of membranes (pPPROM, between 14-24 weeks) for optimal counselling. Therefore, 192 pregnancies of 485 cases which met selection criteria and agreed to follow-up were retrospectively analysed. Mean gestational age at pPPROM was 20.45 weeks. Live births occurred in 171 cases, but 67 (39.2%) of them died in the neonatal period (neonatal death group) and 104 cases (60.8%) constituted surviving neonate group. Of the surviving neonates, 37 (33.7%) experienced at least one complication. Most seen maternal complications were chorioamnionitis (24.48%) and placental abruption (8.33%). Although amniotic fluid volume, length of pPPROM period, completing antibiotherapy and CRP values were significant, amniotic fluid volume and length of pPPROM showed also significance for multivariate regression analysis for maternal risk factors. Risk factors for birth were gestational age at pPPROM, gestational age at birth, new-born weight at birth, 1st and 5th minute Apgar scores, umbilical cord pH value and need for neonatal resuscitation. Furthermore, development of respiratory distress syndrome, necrotising enterocolitis, intraventricular haemorrhage and retinopathy of premature were additional risk factors for neonate. Of them, gestational age at birth, new-born weight at birth, respiratory distress syndrome and retinopathy of prematurity were also significant in multivariate regression analysis.Impact StatementWhat is already known on this subject? Management of previable premature rupture of membranes is controversial and there is no definite consensus on the approach. The factor that best predicts neonatal survival is the gestational age at birth (Deutsch et al. 2010).What do the results of this study add? Appropriate counselling for pPPROM cases is important especially during antenatal period (maternal factors) and postpartum period (neonatal factors). Maternal infection risk is increased with an increased latency period of PPROM. As the gestational age at birth increases, the survival rate increases and neonatal complication rates decrease. Other important determinants of neonatal survival and well-being are the presence of oligo-anhydramnios and latency period of previable PPROM to delivery.What are the implications of these findings for clinical practice and/or further research? Counselling the patient with previable PPROM about pregnancy complications and paediatric outcome is challenging because of the small size, different gestational age ranges, and retrospective nature of the multiple studies on this subject. The most important feature of our study was the relatively high number of patients compared to other series. Thus, we can counsel pregnant women with PPROM prior to 24 weeks of gestation about the maternal antenatal factors and neonatal postnatal factors with related outcomes and help make an informed decision regarding termination or conservative follow-up. Nevertheless, there is a need for larger multicentric prospective studies to validate our data and to establish the prognosis of previable PPROM for both mother and foetus.

Int J Womens Health 2021; 13:627-637. [PMID: 34234574 PMCID: PMC8254139 DOI: 10.2147/ijwh.s303120] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2021] [Accepted: 06/02/2021] [Indexed: 11/23/2022] Open
Abstract
Purpose To determine perinatal outcomes and influence of amniotic fluid volume in pregnancies complicated by previable, preterm prelabor rupture of membranes (pPPROM). Patients and methods This was a historical cohort study from two tertiary-level maternity hospitals (January 1, 2009 to December 31, 2015). All pregnancies complicated by pPPROM were identified using ICD coding of discharge abstracts. Hospital charts were reviewed to collect maternal demographics, pregnancy and delivery events, and immediate postnatal outcomes (including survival). Post-processing review of stored ultrasound images was performed to evaluate the relationship between amniotic fluid volume and outcomes. Results A total of 113 pregnancies were eligible and 99 were included in the final analysis (74 with “expectant management” and 25 opting for elective termination). The median gestational age at pPPROM was 20+6 weeks [IQR 19+4 to 21+5]. For those choosing expectant management, the median latency between pPPROM and delivery was 7 days, median gestational at delivery was 23+1 weeks, and neonatal survival to discharge was 27.5% overall. There was a trend towards higher rates of pregnancy termination at one hospital (31.7%) compared to the other (15.4%), but no difference between sites with respect to latency, mode of delivery, or survival amongst those managed expectantly. There was a relationship between survival and gestational age at pPPROM (p<0.04), as well as initial amniotic fluid volume category: 52.6% of survivors had normal initial amniotic fluid volumes whereas the majority of previable losses had oligohydramnios and the majority of stillbirths had anhydramnios. Conclusion After expectant management, more than one in four newborns following pPPROM survived to hospital discharge. While gestational age at rupture was most strongly correlated with survival, normal initial amniotic fluid volumes were mostly seen in survivors whereas stillbirths more frequently had anhydramnios. These findings will help to improve counseling and care of patients with pPPROM and in guiding long-term follow-up studies.

Abstract
OBJECTIVE Endocan is a novel marker of endothelial inflammation. In this study, we aimed to show whether there was a significant difference between the endocan levels of pregnant women with and without preterm premature rupture of membranes (PPROM and non-PPROM). Also, we aimed to find a relation between endocan levels and the latent period. MATERIAL AND METHODS Pregnant women with PPROM between 28 and 34 weeks of gestation and those without PPROM with similar gestational weeks were included in the study. A total of 88 pregnant women, 44 with PROM and 44 healthy pregnancies, were evaluated. Demographic and obstetric features, leukocyte, and endocan levels of the study and control groups were compared. RESULTS The demographic features and obstetric history of both groups were similar. The mean leukocyte and endocan levels of the study group were higher than in the control group (p < 0.001 and 0.029, respectively). The leukocyte level was the only independent factor predicting PPROM after multivariate logistic regression analysis. CONCLUSION Although the endocan levels were higher in patients with PPROM, multivariate analysis showed that the only independent predictive factor was the leukocyte level.

Abstract
OBJECTIVE The aim of this study was to assess neonatal and maternal adverse outcomes following expectant management of preterm prelabor rupture of membranes (PPROM) between 18 and 26 weeks and to identify maternal morbidity and prognostic factors for neonatal outcomes. METHODS Data were collected from all pregnant women who presented PPROM between 18+0 and 26+0 weeks admitted into two tertiary centers in Brazil from 2005 to 2016. The neonatal adverse outcomes (mortality or the development of a severe morbidity) and maternal adverse outcomes were analyzed and compared among four groups (180/7 to 200/7 weeks, 20+1 to 220/7 weeks, 22+1 to 240/7 weeks and 24+1 to 260/7 weeks). A multiple logistic regression was performed for each predictor of neonatal adverse outcomes, and the area under the receiver operating characteristics curves for birth weight and gestational age at birth were calculated. RESULTS Of the 101 women with PPROM during the study period, 97 fulfilled the eligible criteria. Among these patients, 30 (30.9%) had a miscarriage or stillbirth. Overall there were 67/97 (69.1%) livebirths, 45/97 newborns survived to discharge (46.3%), and 53/97 (54.6%) experienced severe neonatal adverse outcome. The median latency period was seven days, with 36 (37.1%) patients ending the pregnancy in 2-14 days. Among 29 patients with PPROM at 24+1 to 260/7 weeks, only 13 (44.8%) delivered between 2 and 14 days. Multivariate analysis has demonstrated that the independent predictor for adverse neonatal outcome was birthweight. The maternal morbidity was high; however, the expectant management did not increase the rate of severe maternal morbidity. CONCLUSIONS PPROM between 18+0 and 26+0 weeks has high morbidity and mortality, and the only significant independent predictor of severe adverse neonatal outcomes is birthweight. Maternal morbidity is high, however, the expectant management is not increased by expectant management.

Abstract
Objective To describe our hospital's experience following expectant management of previable preterm prelabor rupture of membranes (pPPROM). Study Design Retrospective review of neonatal survival and maternal and neonatal outcomes of pPPROM cases between 2012 and 2019 at a tertiary referral center in South Central Louisiana. Regression analyses were performed to identify predictors of neonatal survival. Results Of 81 cases of pPPROM prior to 23 weeks gestational age (WGA), 23 survived to neonatal intensive care unit discharge (28.3%) with gestational age at rupture ranging from 18 0/7 to 22 6/7 WGA. Increased latency (adjusted odds ratio [aOR] = 1.30, 95% confidence interval [CI] = 1.11, 1.52) and increased gestational age at rupture (aOR = 1.62, 95% CI = 1.19, 2.21) increased the probability of neonatal survival. Antibiotics prior to delivery were associated with increased latency duration (adjusted hazard ratio = 0.55, 95% CI = 0.42, 0.74). Conclusion Neonatal survival rate following pPPROM was 28.3%. Later gestational age at membrane rupture and increased latency periods are associated with increased neonatal survivability. Antibiotic administration following pPPROM increased latency duration.

Abstract
Preterm birth occurs in approximately 10% of all births in the United States and is a major contributor to perinatal morbidity and mortality (). Prelabor rupture of membranes (PROM) that occurs preterm complicates approximately 2-3% of all pregnancies in the United States, representing a significant proportion of preterm births, whereas term PROM occurs in approximately 8% of pregnancies (). The optimal approach to assessment and treatment of women with term and preterm PROM remains challenging. Management decisions depend on gestational age and evaluation of the relative risks of delivery versus the risks (eg, infection, abruptio placentae, and umbilical cord accident) of expectant management when pregnancy is allowed to progress to a later gestational age. 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 when available. Additional guidelines on the basis of consensus and expert opinion also are presented. This Practice Bulletin is updated to include information about diagnosis of PROM, expectant management of PROM at term, and timing of delivery for patients with preterm PROM between 34 0/7 weeks of gestation and 36 6/7 weeks of gestation.

Abstract
Objective: The objective of this study was to assess if maternal and obstetric characteristics other than gestational age at the time of rupture impact short-term neonatal outcomes.Methods: This is a retrospective observational study from a single tertiary care referral center. This study reviewed women with a singleton pregnancy complicated by preterm prelabor rupture of membranes over a 3-year period from May of 2014 through May of 2017. Maternal characteristics and short term neonatal outcomes were collected.Results: We identified 210 pregnancies complicated by preterm prelabor rupture of membranes. Eighteen of these patients had rupture of membranes prior to viability. Of the maternal characteristics at time of admission studied, gestational age at rupture and race influenced short term neonatal outcomes. Women who identified as race other than white had neonates with lower rates of intubation than neonates born to white patients. Gestational age at rupture significantly influenced the neonatal intensive care unit length of stay. Each additional week gained before rupture occurred was associated with a 17.1% decrease in length of stay. Maternal age, gravidity, parity, body mass index, single deepest pocket, and amniotic fluid index did not influence short term neonatal outcomes.Conclusions: Gestational age at rupture of membranes is the most predictive factor associated with short term neonatal outcomes. Race may also influence short term neonatal outcomes. Other maternal characteristics do not seem to influence short term neonatal outcomes. This information can assist with patient counseling on admission for preterm prelabor rupture of membranes and expected neonatal course.

Abstract
Objective: Preterm premature rupture of membranes (PPROM), associated with prematurity, is an important obstetric complication that may cause neonatal mortality and morbidity. The optimal delivery time is controversial in cases with the expectant approach. The fetal effects of long-term exposure to PPROM are unknown. This study aimed to evaluate the maternal and fetal outcomes of expectantly-managed PPROM cases with different latency periods at 240/7-346/7 weeks of gestation.Material and method: The study group consisted of 206 patients at 240/7-346/7 weeks of gestation who met the inclusion criteria. Patients were divided into three groups according to their weeks of PPROM diagnosis as 240/7-286/7, 290/7-316/7, and 320/7-346/7. The period from membrane rupture to delivery was defined as the latency period and divided into three subgroups as 3-7 days, 8-13 days and ≥14 days. In addition to the demographic characteristics of the patients, maternal and obstetric complications, primary and secondary neonatal outcomes were compared between the groups. Primary neonatal outcomes were determined in terms of pathological Apgar scores (<5 at minute 1, <7 at minute 5), requiring resuscitation, admission to Neonatal Intensive Care Unit (NICU) and NICU length of stay. Secondary neonatal outcomes were determined in terms of respiratory distress syndrome, bronchopulmonary dysplasia, intraventricular hemorrhage, retinopathy of prematurity, necrotizing enterocolitis, patent ductus arteriosus, periventricular leukomalacia, and neonatal sepsis. In addition, for the prediction of morbidity and mortality, newborns were evaluated by SNAPPE II (Score for Neonatal Acute Physiology with Perinatal extension-II) consisting of the combination of biochemical and physiological parameters, using the parameters including mean blood pressure (mm/Hg), corporal temperature (°C), PO2/FiO2 ratio, lowest serum pH, multiple seizures, urine output (ml/kg/hr), Apgar score, birth weight, and small for gestational age. The higher the score of SNAPPE II, the higher the morbidity and mortality risk of neonates. For the statistical analysis, the Kruskal Wallis and one-way ANOVA tests were utilized for the numerical data. Categorical data were compared using the chi-square test. The receiver operating characteristic (ROC) test was used to determine the threshold value of the data affecting neonatal morbidity.Results: The mean PPROM week was found to be 29.7 ± 3.0 weeks and the mean delivery week was 31.8 ± 2.5 weeks. The mean latency period for all the patients was 15.1 ± 13.8 days. Clinic chorioamnionitis was observed in 17% of the cases. The lowest chorioamnionitis rate (8.6%) was in the 3-7-day latency period group. Total complications were significantly lower in the 290/7-316/7 week PPROM group in which the latency period was ≥14 days, compared to those in 3-7 days and 8-13 days (p = .001). Total complications were lower in the < 32 weeks PPROM groups in which the latency period was ≥14 days compared to those obtained in 3-7 days and 8-13 days. There was no significant difference between the latency period and total complications after 32 weeks (p = .422). The best discriminative cutoff value of SNAPPE-II for neonatal morbidity was 11.0 (sensitivity 82%, specificity 80%). In the present study, the optimal latency period for the best neonatal outcomes was found to be 34.5 days (sensitivity 70% and specificity 84%) between weeks 240/7-286/7, and 11.0 days between weeks 290/7-316/7 (sensitivity 68% and specificity 85%).Conclusions: Our findings indicated that a long latency period did not increase neonatal morbidity and there was no increase in neonatal complications after 32 weeks of the gestational period compared to those obtained before 32 weeks.

[Antenatal management in case of preterm premature rupture of membranes before fetal viability: CNGOF Preterm Premature Rupture of Membranes Guidelines]. ACTA ACUST UNITED AC 2018; 46:1076-1088. [PMID: 30409732 DOI: 10.1016/j.gofs.2018.10.023] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2018] [Indexed: 12/26/2022]
Abstract
OBJECTIVES To evaluate the maternal, perinatal and long-term prognosis in the event of previable premature rupture of the membranes (PROM) and to specify the interventions likely to reduce the risks and improve the prognosis. METHODS The PubMed database, the Cochrane Library and the recommendations from the French and foreign obstetrical societies or colleges have been consulted. RESULTS Previable PROM is a rare event whose frequency varies from 0.3 to 1% according to estimates (NP4). When occurring as a complication of amniocentesis, the prognosis is generally better than when spontaneous (NP3). Between 23 and 39% of women will deliver in the week following PROM and nearly 40% of women will not have given birth 2 weeks after (NP3). The frequency of medical termination of pregnancy varies greatly according to the studies (NP4), as does that of fetal death (NP4). Hospital survival and survival rates without major morbidity as a proportion of conservatively treated patients range from 17-55% and 26-63%, respectively (NP4). Neonatal prognosis is largely dominated by prematurity and its complications (NP3). The frequency of maternal sepsis varies from 0.8 to 4.8% in the most recent studies (NP4). Only one case of maternal death is reported, although 3 cases were identified in France between 2007 and 2012 (NP3). Information is a major component of the care to be provided to women and their partners (Professional consensus). An initial period of hospitalization may be proposed after previable PROM (Professional consensus). Thereafter, there is no argument to recommend hospital management rather than extra-hospital management when there is no argument in favour of intrauterine infection (Professional consensus). An evaluation of the amount of amniotic fluid by ultrasound may be proposed at the initial consultation and after a period of 7 to 14 days if pregnancy continues (Professional consensus). Prophylactic antibiotic treatment is recommended as soon as PROM is diagnosed (Professional consensus). The gestational age at which corticosteroid therapy may be proposed will depend on the thresholds selected for neonatal resuscitation care. In particular, it will take into account parental positioning (Professional consensus). From the time of the decision to perform neonatal resuscitation until the gestational age of 32 weeks, it is recommended to administer MgSO4 to the woman whose delivery is imminent (Grade A). Tocolysis is not recommended in this context (Professional consensus). In certain situations, meeting strictly the conditions mentioned by the CSP article L. 2213-1, a maternal request for medical interruption of pregnancy may be discussed. CONCLUSION The levels of evidence of scientific work on the management of previable PROM are low, therefore, most of the recommendations proposed here are based on professional agreement by "reasonable" extension of recommendations valid for later gestational ages.
