Management Method

Background: Preterm premature rupture of membranes (PPROM) is a complication responsible for a third of preterm births. Clinical management is initially hospital based, but homecare management is possible if patients are clinically stable 48 h after PPROM. This study set out to determine factors that are predictive of short latency (delivery ≤ 7 days) exceeding 48 h after PPROM, enabling estimation of the prevalence of maternal and neonatal complications and comparison of maternal and fetal outcomes between inpatient and outpatient management. Method: This was a monocentric retrospective study conducted between 1 January 2010 and 28 February 2017 on all patients experiencing PPROM at 24 to 34 weeks + 6 days and who gave birth after 48 h. Maternal, obstetric, fetal, and neonatal variables were included in the data collected. The primary endpoint was latency, defined as the number of days between rupture of membranes and delivery. Results: 170 consecutive patients were analyzed. Short latency could be predicted by the need for tocolysis, a cervical length less than 25 mm at admission and the existence of anamnios. Outpatient follow-up was not found to lead to increased maternal morbidity or neonatal mortality. Conclusion: Our study highlights predictive factors of short latency exceeding 48 h after PPROM. Knowledge of these factors may provide justification for outpatient monitoring of patients presenting with a long cervix, absence of need for tocolysis and persistence of amniotic fluid and, thus, no risk factors after 48 h of admission.

Abstract Objective: A current descriptive assessment of perinatal outcomes in pregnancies complicated by previable preterm premature rupture of membranes (pPPROM) at <24 weeks of gestation, after expectant treatment. Study design: Maternal and short-term neonatal data were collected for patients with pPPROM. Results: Seventy-three patients with 93 fetuses were hospitalized with pPPROM at 15–24 weeks’ gestation. Among these patients, 27.4% (n=20) chose pregnancy termination, 27.4% (n=20) miscarried and 45.2% (n=33) proceeded to live births. After a median latency period of 38 days, ranging from 1 to 126 days, 24 singletons and 20 multiples were live-born, of whom 79.5% (n=35) survived the perinatal period. The main neonatal sequelae were pulmonary hypoplasia (29.5%; n=13), connatal infection (56.8%; n=25), intraventricular hemorrhage (25%; n=11; resulting in five neonatal deaths) and Potter’s syndrome (15.9%; n=7). Nine newborns died, within an average of 2.8 days (range, 1–10 days). The overall neonatal survival rate was 51.5% – including miscarriages but not elective terminations. The intact survival rate was 45.5% of all live-born neonates. Conclusions: Even with limited treatment options, overall neonatal survival is increasing. However, neonatal mortality and morbidity rates remain high. The gestational age at membrane rupture does not predict neonatal outcome.

Abstract Objective: To describe the perinatal outcomes of twin pregnancies with preterm premature rupture of membranes (PPROM) before 34 weeks’ gestation and identify factors associated with discharge without severe or moderate-severe neonatal morbidity.Methods: This study was conducted as a retrospective analysis of twin pregnancies with PPROM occurring at 24 0/7 to 33 6/7 weeks’ gestation. Perinatal outcomes were assessed by gestational age (GA) at PPROM. Factors associated with discharge without severe or moderate-severe neonatal morbidity were identified using logistic regression analysis.Results: Of the 180 pregnancies (360 foetuses), only 17 (9.4%) women remained pregnant 7 days after PPROM. There were 10 (2.8%) cases of prenatal or neonatal death; 303 (84.2%) and 177 (49.2%) neonates were discharged without severe or moderate-severe morbidity, respectively. As GA at PPROM increased, the adverse obstetric and neonatal outcomes decreased, especially after 32 weeks. The GA at PPROM and latency period were both significantly associated with discharge without severe or moderate-severe neonatal morbidity. Pregnancy complications and 5-min Apgar score < 7 increased severe neonatal morbidity.Conclusion: As GA at PPROM increased, the risk of adverse perinatal outcomes decreased. GA at PPROM and latency period were significantly associated with discharge without severe or moderate-severe neonatal morbidity.

The Impact

Objective The aim of the present study was to evaluate the impact of residual anhydramnios following preterm premature rupture of membranes (PPROM) on respiratory distress syndrome (RDS) after the pregnancy was expectantly managed. Methods This study was retrospectively conducted at Erciyes University Medical School, Turkey. It assessed women with singleton pregnancies admitted to the hospital between 2010 and 2020 for expectant management of PPROM between 24th and 28th gestational weeks. The patients were divided into three groups as follows: (1) anhydramnios, (2) oligohydramnios, (3) normal amniotic fluid volume (AFV). Main outcome measure was as follows: The first evaluation was AFV at admission and the primary outcome was a neonatal RDS. Adjusted odds ratios (aOR) and 95% confidence interval (CI) for RDS were calculated for each AFV-at-presentation adjusting for gestational age (GA) at PPROM, GA at delivery, latency period, birth-weight percentile, cesarean birth, and chorioamnionitis. Results Of the 440 women with PPROM, 261 fulfilled the inclusion criteria. There were 125 (47.8%) with normal AFV, 71 (27.3%) with oligohydramnios, and 65 (24.9%) with anhydramnios at admission. The maternal demographic characteristics were similar among the groups. Birth weight was significantly different among the groups. RDS was highest in the anhydramnios group (64.6%). Decreased AFV was not associated with RDS in either oligohydramnios or anhydramnios at presentation. A GA at PPROM, latency period >30 days, and cesarean delivery were co-factors in the outcome. Conclusion Our results indicated that oligohydramnios and anhydramnios were not associated with RDS risk, but GA at PPROM and delivery, latency period, and cesarean delivery were independently associated with the RDS risk.
