Background: Preterm premature rupture of membrane (PPROM) is among the most important cause of the perinatal morbidity and mortality. We sought to determine whether cervical length and amniotic fluid index individually or in combination can predict the pregnancy outcome in cases of PPROM.Methods: The prospective observational study was done on 170 women complicated by PPROM with gestational age between 24-36+6 weeks. They were categorized into three groups Group I.24-28 weeks, Group II.28+1 to 32 weeks and Group III. 32+1 to 36+6 weeks. Cervical length and amniotic fluid index were measured using trans abdominal ultrasound within 24 hr of admission. Maternal outcomes were recorded in terms of latency period, chorioamnionitis, and abruption , and neonatal outcomes were recorded in terms of birth weight, first minute APGAR score <7, NICU admission and early neonatal death. Qualitative variables were correlated using Chi-Square test /Fisher’s exact test. Univariate logistic regression was used to assess cervical length and AFI as a predictor of complication. A p value of <0.05 was considered statistically significant.Results: Out of 170, majority (95) belonged to 28+1 to 32 weeks group. Latency was inversely related to period of gestation (p<0.0001). A long cervical length correlated with increased latency, increased risk of chorioamnionitis and increased neonatal complications in all three groups. Also, women with PPROM having AFI >5 cm had a greater mean latency period (8.32±1.25 days) which increased their risk of developing chorioamnionitis as compared to women with PPROM having AFI ≤5 cm, who had a shorter mean latency period (7.63±1.07 days) and a lower risk of developing chorioamnionitis (p value <0.0001).Conclusions: Latency is inversely related to period of gestation. A long cervical length and increased amount of AFI correlates with increased latency, increased risk of chorioamnionitis and increased neonatal complications.

Adverse Perinatal Outcomes

Objective Amniotic fluid plays a vital protective role in fetal growth and development. Low amniotic fluid index (AFI) during pregnancy increases risk of adverse perinatal outcomes. Prior studies reported association of oligohydramnios (AFI<5 cm) with shorter latency period and inconsistent correlation with chorioamnionitis after preterm premature rupture of membranes (PPROM). We studied effects of oligohydramnios on perinatal outcomes after PPROM. Methods A retrospective cross-sectional study was performed at our medical center on women with PPROM between 23 to 34 weeks during 2014 to 2016. The primary predictor variable was AFI of <5 cm or ≥5 cm in relationship to perinatal outcomes. Results From a total of 117 PPROM cases reviewed, 46 women had AFI<5 cm and 71 had AFI≥5 cm. Length of stay (LOS) in neonatal intensive care unit (NICU) was 42 days for AFI<5 cm versus 26.5 days for AFI>5 cm (p<0.007). The mean neonatal Apgar scores at 1 and 5 minutes (5.2 and 7.4 respectively) were lower in the AFI<5 cm group compared to AFI≥5 cm (6.9 at 1 minute and 8.4 at 5 minutes, p<0.001). Conclusion Oligohydramnios after PPROM is associated with adverse perinatal outcomes such as lower Apgar scores and longer LOS in the NICU. No association was observed with latency period and chorioamnionitis.

IntroductionConservative treatments with latency period have been used for the treatment of preterm premature rupture of membranes (PPROM) in clinical practice, we aimed to evaluate the role and potential influencing factors of latency period, to provide insights to the clinical treatment of PPROM.Material and methodsPPROM pregnant women treated in our hospital from January 1, 2015 to September 30, 2020 were included. PPROM patients were divided into 48～168h group and the >168h latency group, the characteristics and prognosis of this two groups were compared and analyzed. Logistic regression analyses were conducted to analyze the relevant influencing factors of latency period.ResultsA total of 131 PPROM patients were included. There were significant differences on the age, BMI, gestational age on admission, amniotic fluid volume before childbirth, and positive rate of cervical secretion culture between two groups (all p<0.05). Logistic regression analyses indicated that the latency period was shorter in the PPROM patients with age≥30y(OR0.048, 95%CI0.121~0.863) and gestational age≥32w on admission(OR0.463, 95%CI0.069~0.811), and the latency period was prolonged in the PPROM patients with BMI≥23kg/㎡(OR1.591, 95%CI1.134~1.944) and amniotic fluid volume≥6cm(OR2.129, 95%CI1.093~3.042) (all p<0.05). There were significant differences in the incidence of low birth weight and NRDS between 48~168h group and >168h group (all p<0.05).ConclusionsLatency period plays an important role in the PPROM, which is associated with the pregnant women's age, BMI, gestational week of rupture and amniotic fluid index.

SUMMARY Objective: To determine the association between amniotic fluid index (AFI) and perinatal outcomes in preterm premature rupture of membranes (PPROM). Method: A retrospective cohort study was conducted between 2008 and 2012. 86 pregnant women were included, with a diagnosis of PPROM and gestational age from 24 to 35 weeks. Women who presented hypertensive disorders, diabetes, fetuses with birth defects and infection at admission were excluded. To determine the association between AFI and perinatal outcomes, chi-square and Fisher’s exact test were used if necessary, as well as risk ratio (RR) and 95% confidence intervals (95CI). Correlation between AFI and perinatal outcomes was determined by using simple linear regression, and AFI progression during pregnancy was analyzed by Z-test. Results: When comparing newborns presenting ultrasound with AFI<5cm and AFI>5cm, there was a higher frequency of perinatal mortality when the AFI was lower than 5 cm. However, when the oligohydramnios was diagnosed as severe (AFI<3cm), there was a higher frequency of Apgar scores less than seven at 1 minute, neonatal sepsis and early neonatal mortality compared to those presenting AFI>3cm. There was a positive correlation between AFI and gestational age at delivery, birth weight and Apgar scores at minutes 1 and 5. There was also a decrease in amniotic fluid volume with increased gestational age. Conclusion: The presence of severe oligohydramnios after PPROM contributed to a higher frequency of perinatal complications and death.
