Lamellar bodies represent a storage form of pulmonary surfactant within Type II pneumocytes, secretion of which increases with advancing gestational age, thus enabling prediction of the degree of FLM. Preterm premature rupture of membranes (PPROM) complicates approximately 1/3 of all preterm births. Birth within 1 week is the most likely outcome for any patient with PPROM in the absence of adjunctive treatments. Respiratory distress has been reported to be the most common complication of preterm birth. Sepsis, intraventricular haemorrhage, and necrotizing enterocolitis also are associated with prematurity, but these are less common near to term. Objective: To assess the efficacy of the amniotic fluid lamellar body counting from a vaginal pool in predicting fetal lung maturity in women with preterm premature rupture of membranes. Methods: This study was conducted at Ain Shams University Maternity Hospital in the emergency ward from January 2019 to September 2019. It included 106 women with singleton pregnancies, gestational age from 28 - 36 weeks with preterm premature rupture of membranes. This study is designed to assess the efficacy of the amniotic fluid lamellar body counting (LBC) from a vaginal pool in predicting fetal lung maturity in women with preterm premature rupture of membranes. Results: The current study revealed a highly significant increase in the lamellar body count in cases giving birth to neonates without RDS compared to that cases giving birth to neonates with RDS. Also, no statistically significant difference between LBC and age, parity and number of previous miscarriages in the mother was found. Gestational age at delivery was significantly lower among cases with respiratory distress. Steroid administration was significantly less frequent among cases with respiratory distress. However, lamellar bodies had high diagnostic performance in the prediction of respiratory distress. Conclusion: Lamellar body count (LBC) is an effective, safe, easy, and cost-effective method to assess fetal lung maturity (FLM). It does not need a highly equipped laboratory or specially trained personnel, it just needs the conventional blood count analyzer. Measurement of LBC is now replacing the conventional Lecithin/Sphyngomyelin L/S ratio. LBC cut-off value of ≤42.5 × 10<sup>3</sup>/μL can be used safely to decide fetal lung maturity with sensitivity of 95.7% and specificity of 97.6%.展开更多

We aimed to evaluate whether atypical prelabor rupture of membranes (PROM) is a high-risk factor for causing neonatal pneumonia in a prospective real-world study. Patients and Methods: A total of 250 pregnant women at pregnancy week 39 were non-selectively recruited. All were examined by PROM and neonatal pneumonia related clinical, bedside and lab tests, including body temperature, blood pressure, increased vagina discharge, posterior vault pooling, abdominal tenderness, WBC count, nitrazine test, amniotic fluid index, Leakection (a sICAM-1 based lateral flow immunoassay) and vagina streptococcus examinations. Increased vagina discharge with a Leakection positivity was adopted as a working criterium for identifying atypical PROM. Neonatal pneumonia was diagnosed based on the clinical presentation and lab tests. Results: Twenty cases of neonatal pneumonia (8.0%) were diagnosed after the deliveries of the 250 pregnant women. In these neonatal pneumonia cases, 12 (16.7%) occurred in 72 deliveries with atypical PROM, 2 (16.7%) in 12 deliveries with typical PROM, and 6 (3.6%) in 166 deliveries with non-PROM. Conclusion: In this real-world study, we find that a systematic screening at pregnancy week 39 was very meaningful in revealing atypical PROM. Moreover, atypical PROM is a major risk factor for neonatal pneumonia. Therefore, an early diagnosis and intervention on atypical PROM could potentially reduce the occurrence of neonatal pneumonia.展开更多

In particular, the pre-viable PPROM (<23 weeks of gestation) is much more difficult to be treated. The clinical recommendation is to terminate the pregnancy as soon as possible. The pregnancy outcomes of PPROM in the early second-trimester of two twin pregnant women in our hospital were reported to explore the treatment protocols. The pregnancies of the two women developed PROM at 12 and 16 weeks of gestation, respectively. After expectant treatment, they were deliveried successfully at 34+6 and 34+4 weeks of gestation, respectively. The assessment of growth and development of infants was normal during the following six months after birth. Therefore, if PPROM occurs in the early second-trimester of pregnancy, the management of PPROM should be individualized, it’s a long process which should include comprehensive communication between patients and families regarding alternative treatment options (including expectant management) and risks and benefits of the procedure. In the absence of spontaneous labor or occurrence of complications that would prompt delivery (intra-amniotic infection, abruptio placenta, cord prolapse), and fetal status is normal, the patients should proceed with expectant treatment, induction of labor is commonly performed in pregnancies with PPROM ≥34 weeks of gestation.展开更多

In Ethiopia, where maternal mortality is still high, the maternal and fetal outcomes in PROM is very important to decrease maternal and child mortality and for better management and prevention of complications. Thus, this study aimed to detect the maternal and fetal outcomes and associated factors in term PROM at Mizan-Aman General Hospital, south-west Ethiopia.METHODS: A retrospective cross sectional study was conducted using data available at MizanAman General Hospital during a period of 3 years(January 2011 to December 2013). We examined records of 4 525 women who gave birth in the hospital; out of these women, 185 were diagnosed with term PROM and all of them were included in the study. The data of these women were collected using a checklist based on registration books. The data were analyzed using SPSS version 20.0 statistical package. The association between independent and dependent variables was assessed by bivariate and multiple logistic regression analyses. 95%CI and P value less than 0.05 were considered statistically signifi cant.RESULTS: Of the 4 525 women who gave birth in the hospital, 202 were complicated by term PROM. About 22.2% of the women showed unfavorable maternal outcomes. The most common cause of maternal morbidity and mortality was puerperal sepsis. About 33.5% of neonates experienced unfavorable outcomes. The duration of PROM >12 hours(AOR=5.6, 95%CI 1.3–24.1) latency >24 hours(AOR=2.8, 95%CI 1.7–11.8), residing in rural areas(AOR=4.2, 95%CI 3.96–29.4) and birth weight less than 2 500 g were associated with unfavorable outcomes.CONCLUSION: Women residing in rural areas, long latency, and neonates with birth weight less 2 500 g may have unfavorable outcomes. Therefore, optimum obstetric and medical care is essential for the reduction of the devastating complications related to disorders.展开更多

Therefore, optimum obstetric and medical care is essential for the reduction of the devastating complications related to disorders.
文摘目的探讨声诱发反应(acoustic stimulation test,AST)在胎膜早破(prelabor rupture of membranes,PROM)胎儿听力监测中的可行性。方法选取2018年6月—2021年12月宁德师范学院附属宁德市医院妇产科收治的2725例PROM孕妇作为PROM组,根据PROM发生时阴道分泌物病原体检测结果分为生殖道感染(reproductive tract infections,RTI)组(阳性)918例和无RTI组(阴性)1807例;再根据胎龄进一步划分为足月组(孕期≥37周)1792例和早产组(28周≤孕期<37周)933例,为以上受试者行AST检测和新生儿听力筛查及诊断。同时,选取无PROM受试者600例作为对照组,最后将各组结果进行对比。结果RTI组足儿和早产儿的AST阳性率均明显低于无RTI组和对照组,差异有统计学意义(P<0.05);3月龄时,PROM组足月儿和早产儿的声导抗和畸变产物耳声发射(DPOAE)与对照组比较,差异无统计学意义(P>0.05),但其V波阈值明显高于无PROM组;6月龄时,PROM组足月儿和早产儿的声导抗、DPOAE及V波阈值与对照组比较,差异均无统计学意义(P>0.05);在听力损失随访幼儿中,起初超过一半患儿的声导抗异常,而DPOAE通过率低、V波阈值差。随着月龄增加,各组患儿(PROM组足月儿除外)的声导抗异常率、DPOAE通过率及V波阈值均出现明显改善;在阳性AST,PROM组及对照组患儿听力损失多为轻、中度;在阴性AST,PROM组患儿听力损失多为单或双耳中、重度,而对照组则多为同时双耳;AST对筛查胎儿听力损失的曲线下面积(Area under the curve,AUC)为0.821,联合DPOAE的AUC则为0.915,高于单独使用AST或DPOAE,对重度和极重度者具有很好的敏感度。结论AST可以较好地反映与预估PROM宫内胎儿听力,可供临床选择/联合使用;尤其是RTI阴性者,其听力损失率较高,应加强此类患儿的听力跟踪与随访。
文摘目的:探究妊娠合并糖尿病对未足月胎膜早破(PROM)发生率及母婴结局的影响。方法:选取2018年6月—2022年6月于福州福兴妇产医院就诊的糖代谢异常孕产妇400例作为研究组,同期选取于福兴妇产医院行产前检查的糖代谢正常孕产妇400例作为对照组。均行血糖检测,比较两组未足月PROM发生率、母婴结局及妊娠合并糖尿病指标与母婴妊娠结局的相关性。结果:研究组孕产妇未足月PROM发生率为20.5%,显著高于对照组的3.0%,差异有统计学意义(P<0.05);研究组产妇早产、剖宫产、羊水过多、产后出血、妊娠期高血压疾病发生率均明显高于对照组,差异有统计学意义(P<0.05);研究组新生儿发生新生儿窒息、新生儿低血糖、高胆红素血症、新生儿呼吸窘迫综合征(NRDS)、巨大儿及围生儿死亡的比例显著高于对照组,差异有统计学意义(P<0.05);空腹血糖(FPG)、餐后2 h血糖(2 h PG)及糖化血红蛋白(HbA1c)与糖代谢异常孕产妇早产、产后出血、妊娠期高血压综合征呈显著正相关性(r>0,P<0.05),FPG、2 h PG及HbA1c与新生儿窒息、巨大儿、NRDS、新生儿低血糖、高胆红素血症呈显著正相关性(r>0,P<0.05)。结论:孕产妇糖代谢异常会增加未足月PROM发生率,糖代谢异常孕产妇妊娠期高血压疾病、新生儿出现巨大儿发生率仍较高,且糖尿病相关指标与母婴部分结局密切相关,需重视并加强妊娠合并糖尿病的诊断与治疗,降低未足月PROM发生率及母婴并发症,从而降低妊娠风险。
