ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2023; 62:471-485. [PMID: 37128165 DOI: 10.1002/uog.26241] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/19/2023] [Revised: 04/18/2023] [Accepted: 04/24/2023] [Indexed: 05/03/2023]
Abstract
OBJECTIVE To review the evidence on the effect of mode of delivery on perinatal outcome of fetuses born before 32 weeks' gestation. METHODS MEDLINE, Scopus, Cochrane Central Register of Controlled Trials (CENTRAL), the ClinicalTrials.gov registry and gray literature sources were searched, starting from the year 2000 to reflect contemporary practice in perinatal care. Non-randomized or randomized studies that included singleton fetuses without chromosomal abnormality or major congenital defect delivered vaginally or via Cesarean section were eligible for inclusion in the analysis. Primary outcomes were neonatal death, defined as death in the first 28 days of age, and survival to discharge. Secondary outcomes were other adverse perinatal events. The ROBINS-I tool was used to assess the risk of bias. The overall quality of evidence for the outcomes was assessed according to GRADE. Summary odds ratios (ORs) with 95% CIs were calculated, and random-effects models were used for data synthesis. Subgroup analysis was performed for delivery before 28 weeks, delivery between 28 and 32 weeks and according to fetal presentation at delivery. RESULTS A total of 27 retrospective studies (22 887 neonates) were included in the systematic review and meta-analysis, all of which reported on singleton pregnancies. Among cases born before 28 weeks, vaginal delivery significantly increased the risk of neonatal death of fetuses with any type of presentation (n = 1496) (OR 1.87 (95% CI, 1.05-3.35); I2 = 65%, very low quality of evidence) and of fetuses with breech presentation (n = 733) (OR 3.55 (95% CI, 2.42-5.21); I2 = 21%, moderate quality of evidence). The odds of survival to discharge were significantly decreased among fetuses with breech presentation delivered before 28 weeks (n = 646) (OR 0.36 (95% CI, 0.24-0.54); I2 = 21%, low quality of evidence). Among breech fetuses born between 28 and 32 weeks, vaginal delivery increased the odds of perinatal death (intrapartum and neonatal) (n = 1581) (OR 3.06 (95% CI, 1.47-6.35); I2 = 0%, high quality of evidence). In non-cephalic fetuses born between 24 and 32 weeks, vaginal delivery decreased the odds of survival to discharge (n = 1030) (OR 0.28 (95% CI, 0.19-0.40); I2 = 0%, moderate quality of evidence). No significant effect on mortality of mode of delivery was observed in cephalic fetuses at any gestational age. CONCLUSIONS This systematic review and meta-analysis suggests that vaginal delivery in severe preterm birth is associated with an increased risk of neonatal and perinatal death in breech fetuses, while no significant association was observed for cephalic fetuses. © 2023 The Authors.

Abstract
BACKGROUND Preterm premature rupture of membranes (PPROM) is associated with high neonatal morbidity and mortality. However, the influences of cesarean section (CS) on neonatal outcomes in preterm pregnancies complicated with PPROM are not well elucidated. The aim of this study was to investigate the influence of delivery modes on neonatal outcomes among pregnant women with PPROM. METHODS A retrospective cross-sectional study was conducted in 39 public hospitals in 14 cities in the mainland of China from January 1st, 2011 to December 31st, 2011. A total of 2756 singleton pregnancies complicated with PPROM were included. Adverse neonatal outcomes including early neonatal death, birth asphyxia, respiratory distress syndrome (RDS), pneumonia, infection, birth trauma, and 5-min/10-min Apgar scores were obtained from the hospital records. Binary variables and ordinal variables were respectively calculated by binary logistic regressions and ordinal regression. Numerical variables were compared by multiple linear regressions. RESULTS In total, 2756 newborns were involved in the analysis. Among them, 1166 newborns (42.31%) were delivered by CS and 1590 newborns belonged to vaginal delivery (VD) group. The CS proportion of PPROM obviously increased with the increase of gestational age (χ = 5.014, P = 0.025). Compared with CS group, VD was associated with a higher risk of total newborns mortality (odds ratio [OR], 2.38; 95% confidence interval [CI], 1.102-5.118; P = 0.027), and a lower level of pneumonia (OR, 0.32; 95% CI, 0.126-0.811; P = 0.016). However, after multivariable adjustment and stratification for gestational age, only pneumonia was significantly related with CS in 28 to 34 weeks group (OR, 0.34; 95% CI, 0.120-0.940; P = 0.038). There were no differences regarding to other adverse outcomes in the two groups, including neonatal mortality, birth asphyxia, Apgar scores, RDS, pneumonia, and sepsis. CONCLUSIONS The proportion of CS of pregnant women with PPROM was very high in China. The mode of delivery does not affect neonatal outcomes of pregnancies complicated with PPROM.

Abstract
BACKGROUND: Preterm premature rupture of membranes (P-PROM) exerts a tremendous influence on pregnancy prognosis. Additionally, it is a major public health concern, as the cause of up to 40% of all preterm births. AIM: The objective of this study was to identify predictors of Caesarean Delivery in singleton pregnancies complicated by P-PROM. MATERIALS AND METHODS: This is a retrospective observational study of all consecutive singleton P-PROM deliveries (24-37 weeks) over an 18 months at a tertiary referral centre. Pertinent data was collected comprising demographics, obstetric history, pregnancy-associated pathology and delivery from electronic patient records. Univariate statistical analysis comprised Odds Ratio, 95% Confidence interval and Chi-square test with subsequent p-value with statistical significance set at p < 0.05. RESULTS: A total of 240 women delivered singletons following P-PROM over an 18-month period. Maternal age ranged between 12-41 years with an average age of 28 ± 6.27 years. Vaginal delivery (VD) was the predominant mode of delivery, accounting for 52.9% (n = 127) of deliveries. The following parameters were identified as predictors of Caesarean Section (CS) in P-PROM: vaginal infection (p = 0.04), previous CS (p < 0.0001), primiparity (p = 0.004), gravidity > 5 (p = 0.009), university education (p = 0.0006) and prenatal care (p < 0.0001). CONCLUSION: The advantage of CS over vaginal delivery is expedited delivery of the distressed fetus, while that of vaginal delivery entails avoiding postoperative morbidity. However, large multicentric randomised-controlled studies are needed to elucidate this dilemma definitively.

Abstract
OBJECTIVES Preterm premature rupture of fetal membranes (PPROM) exposes the fetus to preterm birth, and optimal timing for delivery is controversial. The aim of this study was to compare intentional early delivery ("active management") with expectant management in very preterm birth (28-32 weeks). STUDY DESIGN We conducted a prospective randomized controlled trial with intent-to-treat analysis, at 19 tertiary-care hospitals in France and 1 in Geneva, Switzerland. Inclusion criteria were women age ≥18 years, PPROM at 280/7 to 316/7 weeks' gestation, singleton pregnancy. Exclusion criteria were maternal/fetal indications for immediate delivery. All participants received prophylactic antibiotics (amoxicillin + gentamicin) and two doses of corticosteroids. Women in expectant management delivered at 34 weeks, sooner if medically indicated. Women in active management delivered 24 h after the second steroid dose. The primary outcome measure was a composite of neonatal death/severe adverse events: periventricular leukomalacia, intraventricular hemorrhage, sepsis, oxygen requirement at 36 weeks, and necrotizing enterocolitis. The secondary outcome was clinical chorioamnionitis. RESULTS The trial was stopped prematurely, due to recruitment difficulties. Of 360 women assessed, 139 (40% of calculated sample size) were randomized: 70 to expectant management, 69 to active management. Mean gestational age at PPROM was similar in both groups (30 ± 1.3 vs. 30.2 ± 1.2 weeks, respectively). There were 35 cases of medical/suspected complications requiring delivery in expectant management vs. 4 in active management. Mean latency between PPROM and delivery was 11.7 ± 9.8 vs. 2.8 ± 0.6 days, respectively; P < 0.0001 (median 8.4 (1.8-44.2) vs. 2.7 (1.9-4.3)). There were more caesarean deliveries in active than expectant management (80% vs. 60%, respectively; P < 0.01). There were 2 chorioamnionitis cases, both in expectant management. One baby died in expectant management; 2 in active management (one with heart defect). There was no significant difference in sepsis rates. The combined neonatal death/severe adverse events measure was 12.9% for expectant management and 13.0% for active management (OR 0.98; 95% CI: 0.33-2.93, P = 0.97). CONCLUSION For PPROM at 28-32 weeks, and with antenatal antibiotic and steroid therapy, there were no observed differences in neonatal health when comparing expectant management to early delivery. As expected, expectant management resulted in higher gestational age and birth weight. However, our study was underpowered to draw firm and reliable conclusions.

Impact of mode of delivery on pregnancy outcomes in women with premature rupture of membranes after 28 weeks of gestation in a low-resource setting: A prospective cohort study.

Abstract
Background Despite the high prevalence of premature rupture of membranes (PROM) in low-resource settings, the preferred mode of delivery remains unclear. We compared the perinatal mortality in a prospective cohort of women with PROM after 28 weeks following vaginal or caesarean delivery at Mulago Hospital with the aim of adopting evidence based practice and improving patient care. Methods Between November 2015 and May 2016, 1455 women with PROM after 28 weeks of gestation and their newborns were prospectively followed from admission to discharge at Mulago Hospital. The primary outcome was perinatal mortality. Secondary neonatal outcomes included sepsis and admission to the Special Care Unit. Maternal outcomes included maternal deaths and complications. Outcomes were compared between women who had vaginal vs. caesarean delivery using multivariable logistic regression. All statistical tests were 2-sided with the level of statistical significance set at p < 0.05. Results The incidence of PROM was 12.1%. The perinatal mortality following PROM was 65 per 1000 live births. Of the 1425 women with PROM, 991 (69.5%) had vaginal delivery and 434 (30.5%) underwent Caesarean section. There was no statistical difference in perinatal mortality by the mode of delivery (vaginal vs. caesarean) in PROM (p = 0.12). The risk factors for perinatal mortality included chorioamnionitis, failure to administer corticosteroids in preterm PROM, gestational age (28–33 weeks), duration of drainage of liquor (24–48 hours), and presence of maternal complications. Caesarean delivery was associated with increased maternal postpartum infections, admission to the Special Care Unit and maternal death. Conclusion In low resource settings, vaginal delivery is the preferred mode of delivery for PROM after 28 weeks gestation. It is associated with lesser maternal and perinatal morbidity when compared to caesarean delivery.

Abstract
OBJECTIVE Antibiotic administration is a standard practice in preterm premature rupture of membranes (PROM). Specific anti-microbial agents often include ampicillin and/or erythromycin. Anaerobes and genital mycoplasmas are frequently involved in preterm PROM, but are not adequately covered by antibiotics routinely used in clinical practice. Our objective was to compare outcomes of PROM treated with standard antibiotic administration versus a new combination more effective against these bacteria. STUDY DESIGN A retrospective study compared perinatal outcomes in 314 patients with PROM <34 weeks receiving anti-microbial regimen 1 (ampicillin and/or cephalosporins; n = 195, 1993-2003) versus regimen 2 (ceftriaxone, clarithromycin and metronidazole; n = 119, 2003-2012). Intra-amniotic infection/inflammation was assessed by positive amniotic fluid culture and/or an elevated amniotic fluid MMP-8 concentration (>23 ng/mL). RESULTS (1) Patients treated with regimen 2 had a longer median antibiotic-to-delivery interval than those with regimen 1 [median (interquartile range) 23 d (10-51 d) versus 12 d (5-52 d), p < 0.01]; (2) patients who received regimen 2 had lower rates of acute histologic chorioamnionitis (50.5% versus 66.7%, p < 0.05) and funisitis (13.9% versus 42.9%, p < 0.001) than those who had received regimen 1; (3) the rates of intra-ventricular hemorrhage (IVH) and cerebral palsy (CP) were significantly lower in patients allocated to regimen 2 than regimen 1 (IVH: 2.1% versus 19.0%, p < 0.001 and CP: 0% versus 5.7%, p < 0.05); and (4) subgroup analysis showed that regimen 2 improved perinatal outcomes in pregnancies with intra-amniotic infection/inflammation, but not in those without intra-amniotic infection/inflammation (after adjusting for gestational age and antenatal corticosteroid administration). CONCLUSION A new antibiotic combination consisting of ceftriaxone, clarithromycin, and metronidazole prolonged the latency period, reduced acute histologic chorioamnionitis/funisitis, and improved neonatal outcomes in patients with preterm PROM. These findings suggest that the combination of anti-microbial agents (ceftriaxone, clarithromycin, and metronidazole) may improve perinatal outcome in preterm PROM.

Abstract
Prematurity is a frequent event and clearly raises an issue concerning how these fetuses with multiple weaknesses should be delivered. Although, a systematic abdominal approach has no scientific basis, there are cases where the caesarean is chosen because of other factors associated to prematurity such as any maternal or fetal indication to terminate the pregnancy while labour induction remains impossible. However, in case of breech presentation, which is often delivered by caesarean, the literature does recommend neither the vaginal nor the abdominal approach. Caesarean in case of prematurity is more difficult because of the absence of any inferior segment and implies making a large incision so as to easily extract these weak fetuses. Increased maternal morbidity related to preterm caesarean sections has been reported through out literature. The viability gestational age limit represents a confounding factor in most studies since caesarean is rarely chosen for these fetuses because of a very low expected survival rate, while it is probably in this situation that the abdominal approach could provide a real benefit. Larger studies are required to show potential advantages. Systematic use of episiotomies or instrumental deliveries in case of vaginal births is not recommended in case of prematurity. Protecting the fetal head with spatulas still requires further evaluations.
