A study on feto-maternal outcome in patients with preterm premature rupture of membranes

Background: Preterm premature rupture of membranes (PPROM) is rupture of fetal membranes prior to labor in pregnancies between 28-37 weeks. PPROM is associated with significant maternal and neonatal morbidity or mortality. The present study was conducted to evaluate risk factor and etiology of PPROM and its fetomaternal effect in tertiary care hospital.Methods: A cross-sectional study was conducted in the department of obstetrics and gynaecology, SMS Hospital, Ahemdabad. From August 2023 to February 2024.The study included 50 pregnant women between 28-37 weeks gestation with PPROM were subjected to detailed history and examination. Each patient was followed till her delivery and fetomaternal outcome was recorded.Results: PPROM is a fair complication of pregnancy. 80% were belongs to 20-29 age, 70% were unbooked, 76% from low SE-class, 68% with gestational age of 34-36 weeks. Vaginal delivery was common 58%. The babies born to mothers with PPROM more in weight of 2-2.5 kg (48%). 34 had no risk factors to develop PPROM. Most common etiology for PPROM infection 16% and malpresentation 10%. Most of the mothers with PPROM had no complications. 17 (34%) babies required NICU admissions for complaints of premturity, respiratory distress, birth asphyxia, and sepsis. RDS was most common neonatal complication. 2 neonatal deaths in this study due to RDS and prematurity.Conclusions: Effective PPROM Mx involves evaluating the risks and advantage of conservative Mx strategies. Whenever possible, Rx should be focused towards prophylactic use of antibiotics and steroids during pregnancy can reduce fetal and mother morbidity and mortality. Termination of pregnancy should be considered at the 1st sign of chorioamnionitis.

Comparison of platelet to lymphocyte ratio and neutrophil to lymphocyte ratio in women with preterm premature rupture of membranes and women with preterm delivery

Background: Considering the adverse effect of PROM on birth outcomes and the condition of mother and fetus, early identification of risk factors of PROM and their control can reduce the occurrence of adverse outcomes for mother and fetus and improve their health. This study was conducted with the aim of comparing PLR and NLR in women with PROM and women with preterm delivery. Methods: This case-control study was conducted on 155 women with PPROM as case group and 155 women with preterm delivery as control group. Age, gestational age, type of delivery, baby's birth weight, gravida, parity, APGAR score, rate of hospitalization in Neonatal Intensive Care Unit (NICU), occurrence of neonatal sepsis and development of respiratory distress syndrome (RDS) were recorded from women's medical records. Also, the results of blood tests and PLR and NLR values were calculated for each pregnant woman. Collected data were analyzed by statistical methods in SPSS version 24. Results: The average gestational age and weight of babies at birth time in the case group were significantly lower than those with preterm delivery. The mean of NLR in case group with 4.8±2.5 was significantly higher than control group with 4.2±2.2. The mean of PLR in case group with 111.5±47.6 was significantly higher than control group with 100.98±43.4. Conclusions: The high values of PLR and NLR in the women with PROM compared to women with preterm delivery can be a marker to identify the risk of PPROM in pregnant women.

A study of fetal outcome in patients with premature rupture of membranes with gestational age more than 28 weeks

Background: Premature rupture of membranes is rupture of membranes before the onset of labour irrespective of gestational age. If it occurs before 37 weeks, it is called as preterm premature rupture of membranes (PPROM). Once PROM delivery is inevitable, so neonatal prognosis depends on gestational age at which PROM occurs. Neonatal complications include prematurity and its complications mainly, also pulmonary hypoplasia due to severe oligohydramnios, skeletal and joint deformities to foetus due to compression, increased risk of neurodevelopmental impairment and neonatal white matter damage. PROM is a still one of the most difficult and controversial problems in obstetrics.Methods: A prospective longitudinal study was conducted in Department of Obstetrics and Gynaecology at a tertiary care hospital from 2021 to 2023 (18 months). A total of 275 patients admitted with complaints of per vaginal leaking with gestational age more than 28 weeks were studied. A multivariate analysis was used to find association between PROM and foetal outcome.Results: In this study, 57% (157) new-borns had birth weight >2.5 kgs, 60% (166) new-borns had APGAR score 8/10, 71% (196) new-borns were term, 40% (109) had NICU stay, 6% (17) had respiratory distress syndrome (RDS), 3% (8) had neonatal sepsis, 2% (6) had neonatal hypoglycaemia and perinatal mortality rate was 1% (3).Conclusions: Once there is PROM, delivery is imminent. Neonatal outcome can be improved significantly after administration of steroids and antibiotics. To get that time short term tocolysis can be used. During that time foeto-maternal monitoring should be done for early detection of chorioamnionitis. Looking after preterm infants puts an immense pressure on family, economy and health care resources. The prevention of PROM is difficult so more focus should be on management of PROM.

High diversity in the vaginal microbiome in women following preterm premature rupture of membranes and its effect on fetomaternal outcome

Background: Premature rupture of the membranes (PROM) complicates 3% of pregnancies and its associated with adverse perinatal outcome. Methods: This was a case control study conducted over a period of two years. Our aim was to evaluate the bacterial colonization of genital tract of antenatal patients who presented with preterm premature rupture of membranes and their maternal and neonatal complications. We studied 6023 patients during our study period among which 156 patients presented with preterm premature rupture of membranes. Results: PPROM was found more commonly among age 25-30 years (46.79%) with p<0.001. Out of 156 pregnant women with PPROM, only 16 patients (10.26%) developed clinical chorioamnionitis. We observed that 43.59% patients (n=68) with PPROM underwent LSCS which was significantly higher than control group (19.93%). Among them 81.41% (n=127) of the patients delivered within 24 hours of admission. Among 156 patients, 94 (59.12%) mothers had babies with birth weight ranging between 1.5-2.5 kg as compared to control group where 30.51% mothers had low birth weight babies. The difference was statistically significant. Approximately 18.24% babies developed respiratory distress syndrome requiring ICU care in study group as compared to 3.03% in control group and the difference was statistically significant. Conclusions: It is important to diagnose the PPROM early and manage the patient until delivery for better outcome. Timely intervention after proper analysis of risk and benefit of early termination helps in reducing adverse perinatal outcomes, reduced NICU admissions and unnecessary interventions for neonates.

A study of maternal outcome in patients with premature rupture of membranes with gestational age more than 28 weeks

Background: Premature rupture of membranes is rupture of membranes before the onset of labour irrespective of gestational age. PROM is associated with variety of maternal complications from chorioamnionitis, unfavourable cervix, dysfunctional labour to caesarean rates, postpartum haemorrhage and endometritis in mother. PROM is a still one of the most difficult and controversial problems in obstetrics.Methods: This was a prospective longitudinal study conducted in a tertiary care hospital from 2018 to 2020 (18 months). Total 275 patients admitted with complaints of per vaginal leaking with gestational age more than 28 weeks were studied. A multivariate analysis was used to find association between PROM and maternal outcome.Results: PROM was common in women belonging to low socio-economic status (68%). Most of the cases were unbooked (73%), primigravida (42%) belonging to age group 21-25 yrs. (46%), and had gestational age more than 37 wks. (71%). 62% of cases delivered vaginally while remaining underwent LSCS, most common indication being oligohydramnios (35%). Post partum fever (14%) was most common morbidity followed UTI (7%).Conclusions: In present study, PROM was common in unbooked cases and women belonging to low socioeconomic status. Asymptomatic bacteriuria was most common predisposing factor. Maternal morbidity corresponds to duration between PROM and delivery. Early diagnosis and appropriate management reduces hospital stay and maternal morbidity.

Management of preterm premature rupture of membrane in a high-risk pregnancy

Preterm premature rupture of membranes (PPROM) usually has a multi factorial aetiology that is often unknown, although the most frequently reported cause is infection, others could be cervical insufficiency, over distention of uterine cavity, previous history of preterm labor, systemic inflammatory disease etc. This case report documented a rare incidence of preterm premature rupture of membranes, in a 35-year-old female with past history of 8 spontaneous abortions and 1 ectopic pregnancy. Patient had an IVF conception, amenorrheic for 7 months and 2 weeks, and came with a complaint of white discharge per vaginum. On per speculum examination, cervical os was found dilated. The patient was managed conservatively with protein and progesterone support along with prophylactic tocolytics and antibiotics, till early signs of chorioamnionitis were noticed. The decision of induction of labour and eventually preterm premature rupture of membranes lead to emergency cesarean section. Challenges faced in managing this high risk pregnancy are discussed, emphasizing the need of close monitoring and tailoring management in similar circumstances.

High neutrophils to lymphocytes ratio in maternal blood serum as risk factor for preterm premature rupture of membrane

Background: Neutrophil-to-lymphocyte ratio has been extensively studied as a prognostic factor for various diseases based on systemic inflammation. Premature rupture of membranes is an obstetric problem that does not only occur in term pregnancies but can also occur in preterm pregnancies. One of the main etiologies for premature rupture of membranes is inflammation. Knowing the difference in the NLR between preterm premature rupture of membranes and without PPROM is important to increase understanding of the crucial role of NLR in predicting the incidence of PPROM. Methods: This analytic case-control study compared NLR values ??in maternal blood serum between PPROM and without PPROM. This research was conducted in the emergency delivery room and obstetrics and gynecology outpatient clinic at Prof. dr. I.G.N.G. Ngoerah Hospital Denpasar from February to June 2022. Results: A high NLR in maternal blood serum may be a risk factor for PPROM. Patients with a high NLR had a 4.5 times greater likelihood of experiencing PPROM than those with a low NLR (OR=4.5; 95% CI=1.4-13.83; p=0.007). Conclusions: A high NLR in maternal blood serum is a marker of inflammation with an increased risk of 4.5 times for the occurrence of PPROM.

Feto maternal outcomes of fibroid in pregnancy: a retrospective observational study

Background: Uterine fibroid is one of the most common intrauterine masses among females at the reproductive age. Although most of the uterine fibroids are asymptomatic during pregnancy, serious complications may occur. Aim of this study was to assess the obstetric outcome (maternal and fetal) in pregnancy with fibroid.Methods: A retrospective observational study was performed at Obstetrics and Gynecology Department in ABVIMS and RML hospital. 50 pregnant patients with >2 cm size fibroids were taken in the study. Maternal age, parity, size of the fibroid, complications during pregnancy, and mode of delivery were noted.Results: The 20% of pregnancies ended up in spontaneous abortions. 60% of them had to undergo caesarean section out of which, 10% was for non-progress of labor (NPOL), 5% for outlet obstruction, 5% with malpresentation, 16% patients with APH, 4% patients had elective LSCS for placenta previa and 10% with previous cesarean who were not willing for vaginal delivery. Other complications; placenta previa 16% and low lying placenta 10% patients, pre-eclampsia 20%, malpresentation 20%. Post-partum hemorrhage (PPH) was seen in 24% of the cases. 4% cases had red degeneration which were managed conservatively. Neonatal outcomes included 30% of babies born preterm, 40% being small for gestational age, 10% having low 1-minute APGAR score and 4% with low APGAR at 5 and 10 min. 30% had NICU admission for varied reasons.Conclusions: Fibroids in pregnancy may be associated with complications affecting the course of pregnancy and labor. So, pregnancy must be cautiously monitored in the antenatal period, through regular follow-up.

Ruptura prematura de membranas ovulares / Premature rupture of ovular membranes

La ruptura prematura de las membranas ovulares se define como la pérdida de la integridad del amnios y corion antes del inicio del trabajo de parto, afecta el 3 % de los embarazos, causa un tercio de los partos pretérminos, los cuales ocupan el 10,49 % de los nacimientos y es el origen de altos índices de morbimortalidad perinatal. En la actualidad, el manejo de esta patología se orienta principalmente en evitar los factores de riesgo, hacer un diagnóstico adecuado, determinar la edad gestacional en que ocurre, realizar el monitoreo exhaustivo del bienestar materno-fetal y en decidir el momento idóneo de finalización de la gestación para minimizar sus complicaciones. Debido a la compleja y lábil estructura histológica de las membranas ovulares, se ha dejado a un lado el tratamiento directo de la entidad el cual sería sellar o reparar el defecto en sí. En los últimos años, numerosos estudios y protocolos clínicos de prestigiosos centros asistenciales han servido como guía para el manejo de esta entidad, pero en muy pocos se observa una terapia destinada a la reparación de dichas membranas o en sellar tal defecto. Las evidencias científicas demuestran que la regeneración y reparación de las membranas es lenta y compleja y los tratamientos propuestos para reparar o sellar su defecto no han gozado de la aceptación científica para su aprobación, sin embargo, el uso del parche hemático transvaginal endocervical autólogo luce como una alternativa terapéutica prometedora(AU)

The premature rupture of the ovular membranes is defined as the loss of the integrity of the amnion and chorion before the on set of labor, affects 3% of pregnancies, causes athird of preterm births which occupy 10,49% of births and is the origin of high rates of perinatal morbidity and mortality. At present, the management of this pathology is mainly oriented towards avoiding risk factors, making an adequate diagnosis, determining the gestational age in which it occurs, carrying out exhaustive monitoring of maternal-fetal well-being and deciding the ideal moment to end the treatment. Pregnancy to minimizeits complications. Due to the complex and labile histological structure of the ovular membranes, the direct treatment of the entity has been set a side, which would be to seal or repairthe defect it self. In recent years, numerous studies and clinicalprotocols from prestigious health care centers have served as aguide for the management of this entity, but very few have observed a therapy aimed at repairing said membranes or sealing such a defect. Scientific evidence shows that the regeneration and repair of the membranes is slow and complex and the treatment sproposed to repair or seal their defect have not enjoyed scientific acceptance for their approval, how ever, the use of the autologous endocervical transvaginal blood patch looks like a promising therapeutic alternative(AU)

Expectant management for a high-risk pregnancy patient who had preterm premature rupture of membranes with placenta and vasa praevia plus velamintous cord insertion

Objective of the study was to share a case of high risk pregnancy with premature preterm rupture of membranes (PPROM), placenta and vasa praevia plus velamintous cord insertion. PPROM carries the risk of increasing rates of neonatal respiratory distress syndrome, neonatal brain prematurity, and electrolyte imbalance. Having placenta previa and vasa praevia carries a significant risk of recurrent bleeding and increases the risk of making the pregnancy threatened by the antepartum haemorrhage with the chance of losing the baby and subsequent morbidities and mortalities to the mother and the baby. The velamentous cord insertion is linked to decreased foetal growth and premature births. Herein, we present the case of 28 years old that had multiple risk factors during her pregnancy in the form of having multiple miscarriages, stillbirth, PPROM early at 20 weeks of her gestation, placenta praevia, vasa praevia and velamentous cord insertion. Moreover, despite the above risk factors, which made the pregnancy very high risk, by expectant and management plans, we could push her pregnancy to reach near maturity and deliver her baby safely without complications either to the mother or to her baby. It could be theoretically imagined that the placenta praevia worked as a sealed system or a valve and prevented more leakage of the liquor in this PPROM case. Besides that, we can consider that the cervical stitch she had at 14 weeks, had a role in narrowing the cervical canal and decreasing the diameter of the membrane that has ruptured.

Characteristics of vaginal microbiota in pregnant women with premature rupture of membranes and establishment of prediction model / 中华微生物学和免疫学杂志

Objective:To study the characteristics of vaginal microbiota in pregnant women with premature rupture of membranes (PROM) and to establish prediction models for PROM.Methods:This study involved 35 women with preterm premature rupture of membranes (PPROM), 180 with term premature rupture of membranes (TPROM) and 255 term birth cases without premature rupture of membranes (TBWPROM, control group). The V3-V4 hypervariable region sequences in the vaginal samples collected at 16-28 weeks of gestation were detected by 16S rRNA gene next-generation sequencing. The differences in Alpha and Beta diversity, and the attributes and metabolic function prediction of each recognized species among the three groups were analyzed. Subsequently, a random forest model was used to establish the prediction models for PROM using vaginal microbiota species and environmental risk factors.Results:Compared with the control group, the Alpha diversity of the PPROM group was higher (Observed features, P=0.022; Faith_pd index, P=0.024) and Beta diversity was also significantly different (Unweighted UniFrac, P=0.010; Jaccard index, P=0.008). In PPROM cases, Megasphaera genomosp. typeⅠ was significantly increased ( P=0.017) and Lactobacillus mulieris was significantly decreased ( P=0.003). In the patients with TPROM, Megasphaera was significantly increased ( P=0.009) and Lactobacillus mulieris was significantly decreased ( P=0.002). In terms of functional pathways, sulfur oxidation ( P=0.021), methanogenesis from acetate ( P=0.036), L-histidine biosynthesis ( P=0.009), adenosylcobalamin biosynthesis ( P=0.041) and fucose degradation ( P=0.001) were significantly increased in patients with PPROM; L-histidine biosynthesis ( P<0.001) and fucose degradation ( P=0.030) were significantly increased in patients with TPROM. The prediction models were established using the random forest model with vaginal microbiota species and environmental risk factors and the prediction model for PPROM performed well [AUC: 0.739 (95%CI: 0.609-0.869), sensitivity: 0.928, specificity: 0.659, positive predictive value: 0.750, negative predictive value: 0.906], which had a certain reference value. Conclusions:Vaginal microbiota might be related to the development and progression of PROM. Studying the differences in vaginal microbiota might provide a new idea for the prevention and treatment of PROM. Functional prediction provided a direction for further research on the mechanism of PROM. The established prediction model could prevent the occurrence of PPROM and promote maternal and infant health.

Predictive value of serum inflammatory markers for histological chorioamnionitis among women with preterm premature rupture of membranes after undergoing cervical cerclage

ABSTRACT Purpose: To determine the predictive value of maternal White Blood Cells (WBC), neutrophils, and C-Reactive Protein (CRP) for diagnosing Histological Chorioamnionitis (HCA) among women with Preterm Premature Rupture of Membranes (PPROM) who underwent cervical cerclage. Methods: A retrospective cross-sectional study was conducted among women with singleton pregnancy and PPROM, who underwent cervical cerclage during 2018-2020. Results: A total of 55 eligible women were included in the final analysis, including 36 (61.02%) cases with HCA and 19 (38.98%) without HCA. Women with HCA had higher WBC count (12.31 ± 2.80) × 109/L and neutrophil count (9.67 ± 2.90)×109/L than those without HCA (10.35 ± 2.53) × 109/L and 7.82 ± 2.82 × 109/L, respectively) (both p < 0.05). The cut-off value of WBC count at 10.15×109/L was found to be the most effective in identifying HCA, with an Area Under Curve (AUC) of 0.707 (95% CI: 0.56-0.86; p = 0.012), sensitivity of 86.11%, specificity of 57.90%, Positive Predictive Value (PPV) of 79.49%, Negative Predictive Value (NPV) of 68.75%, and Youden index of 0.44. The combination of WBC + neutrophil had a slightly higher (AUC = 0.711, 95% CI: 0.57-0.86; p = 0.011), specificity (68.42%), and PPV (81.25%), but lower sensitivity (72.22%), than the WBC count alone. A cut-off value of neutrophil at 7.46 × 109/L was effective in identifying HCA, with an AUC of 0.689 (95% CI: 0.53-0.84; p = 0.022). Discussion: Combination use of WBC+neutrophil was found to be the most accurate predictor of HCA among women with PPROM after surgery of cervical cerclage.

El prematuro tardío, ¿qué sabemos desde el punto de vista perinatal? / The late premature, what do we know from the perinatal point of view?

Resumen El parto prematuro es la principal causa de morbimortalidad neonatal en Chile. Los prematuros tardíos, definidos como nacimientos entre 34 semanas con 0 días (34+0) y 36 semanas con 6 días (36+6) de gestación, representan el 70-80% de los prematuros y se asocian a baja morbilidad y excepcional mortalidad si se comparan con partos bajo 34 semanas, pero significativamente mayor al compararlos con partos de término. Los prematuros tardíos son el resultado de diversas condiciones obstétricas, tales como síndromes hipertensivos del embarazo, rotura prematura de membranas, colestasia intrahepática del embarazo y comorbilidad médica. El propósito de esta revisión es actualizar la información asociada a los prematuros tardíos y dar una visión de las tendencias en el uso de corticoides y el manejo expectante de la rotura prematura de membranas con el objetivo de disminuir las complicaciones en este grupo de prematuros.

Abstract Preterm delivery is the most important cause of neonatal morbidity and mortality in Chile. Late preterm, defined as deliveries between 34 +0 and 36+6-weeks accounts for 70-80% of preterm and is associated with non-severe morbidity and extremely low mortality when compared with deliveries below 34 weeks but significantly high when compared with full term babies. Late preterm deliveries are a result of several obstetric conditions, such a hypertensive disorder, premature rupture of membranes, intrahepatic cholestasis, and maternal medical comorbidities. The purpose of this review is to update the information associated with the risks of late preterm and to guide in the new trends in the application of steroid and expectant management for premature rupture of membranes in order to reduce the frequency of late preterm.

Beneficios de los antibióticos en la rotura prematura de membranas de pretérmino y factores que intervienen en la eficacia del tratamiento: revisión narrativa / Benefits of antibiotics in preterm premature rupture of membranes and factors involved in the efficacy of the treatment: narrative review

Resumen El parto prematuro es la principal causa de morbilidad y de mortalidad perinatal, y hasta un tercio de los casos presentan rotura prematura de membranas. La infección intrauterina que asciende desde la vagina es su principal causa en un hospital público de Chile. Esta revisión narrativa mediante búsqueda en PubMed, Cochrane, Embase, Scielo, Science Direct y Wiley Online Library incluye estudios publicados sobre los diferentes factores infecciosos que intervienen en el resultado adverso perinatal y la eficacia de los antibióticos en la rotura prematura de membranas de pretérmino. Además, contiene recomendaciones de sociedades científicas sobre el uso de antibióticos en estos casos. Los ensayos concluyen que los antimicrobianos prolongan el embarazo, disminuyen la corioamnionitis clínica y reducen variadas morbilidades neonatales, pero no reducen la mortalidad perinatal ni las secuelas tardías en la infancia. Los resultados adversos obstétricos, especialmente los neonatales, y las secuelas dependen de la existencia de invasión microbiana de la cavidad amniótica o de infección cérvico-vaginal, de la virulencia de los microorganismos aislados, del compromiso inflamatorio/infeccioso de la placenta (corioamnionitis histológica, funisitis) y de la respuesta inflamatoria fetal. Para mejorar los resultados adversos obstétricos neonatales en la rotura prematura de membranas de pretérmino, los esquemas de antibióticos deben ser eficaces, cubriendo el amplio espectro microbiológico existente y actuando sobre los factores infecciosos implicados en la gravedad de la infección. Además, deben administrarse de manera intensiva y prolongada hasta el parto.

Abstract Preterm birth is the leading cause of perinatal morbidity and mortality, and up to a third of them have premature rupture of membranes. Intrauterine infection that rises from the vagina is its main cause in a public hospital in Chile. This narrative review by searching PubMed, Cochrane, Embase, Scielo, Science Direct and Wiley Online Library includes published studies of the different infectious factors involved in perinatal adverse outcome and of the efficacy of antibiotics in preterm premature rupture of membranes. It also contains recommendations from scientific societies on the use of antibiotics in these cases. These trials conclude that antimicrobials prolong pregnancy, decrease clinical chorioamnionitis, and reduce various neonatal morbidities, but do not reduce perinatal mortality or infant sequelae. Obstetric and especially neonatal adverse outcomes in these patients depend on the existence of microbial invasion of the amniotic cavity and/or cervicovaginal infection, of the virulence of the isolated microorganisms, of inflammatory/infectious involvement of the placenta (histological chorioamnionitis, funisitis) and fetal inflammatory response. To improve adverse neonatal obstetric outcomes in preterm premature rupture of membranes, antibiotic regimens must be effective, covering the wide existing microbiological spectrum and acting on infectious factors responsible for the severity of the infection. In addition, they must be administered aggressively and for a long time until delivery.

Active versus expectant management for preterm premature rupture of membranes at 34-36 weeks of gestation and the associated adverse perinatal outcomes / Manejo ativo versus expectante para ruptura prematura de membranas entre 34 e 36 semanas de gestação e os resultados perinatais adversos associados

Abstract Objective: To compare the type of management (active versus expectant) for preterm premature rupture of membranes (PPROM) between 34 and 36 + 6 weeks of gestation and the associated adverse perinatal outcomes in 2 tertiary hospitals in the southeast of Brazil. Methods: In the present retrospective cohort study, data were obtained by reviewing the medical records of patients admitted to two tertiary centers with different protocols for PPROM management. The participants were divided into two groups based on PPROM management: group I (active) and group II (expectant). For statistical analysis, the Student t-test, the chi-squared test, and binary logistic regression were used. Results: Of the 118 participants included, 78 underwent active (group I) and 40 expectant management (group II). Compared with group II, group I had significantly lower mean amniotic fluid index (5.5 versus 11.3 cm, p = 0.002), polymerase chain reaction at admission (1.5 versus 5.2 mg/dl, p = 0.002), time of prophylactic antibiotics (5.4 versus 18.4 hours, p < 0.001), latency time (20.9 versus 33.6 hours, p = 0.001), and gestational age at delivery (36.5 versus 37.2 weeks, p = 0.025). There were no significant associations between the groups and the presence of adverse perinatal outcomes. Gestational age at diagnosis was the only significant predictor of adverse composite outcome (x2 [1] = 3.1, p = 0.0001, R2 Nagelkerke = 0.138). Conclusion: There was no association between active versus expectant management in pregnant women with PPROM between 34 and 36 + 6 weeks of gestation and adverse perinatal outcomes.

Resumo Objetivo: Comparar o tipo de manejo (ativo versus expectante) para ruptura prematura de membranas (PPROM, na sigla em inglês) entre 34 e 36 semanas e 6 dias de gestação e os resultados perinatais adversos relacionados, em 2 hospitais terciários do sudeste brasileiro. Métodos: No presente estudo de coorte retrospectivo, os dados foram obtidos através da revisão dos prontuários de gestantes internadas em dois centros terciários com protocolos diferentes para o seguimento da PPROM. As gestantes foram divididas em dois grupos com base no manejo da PPROM: grupo I (ativo) e grupo II (expectante). Para análise estatística, foram utilizados o teste t de Student, qui-quadrado e regressão logística binária. Resultados: Das 118 gestantes incluídas, 78 foram submetidas a tratamento ativo (grupo I) e 40 a seguimento expectante (grupo II). Comparado ao grupo II, o grupo I apresentou índice de líquido amniótico médio significativamente menor (5,5 versus 11,3 cm, p = 0,002), reação em cadeia da polimerase na admissão (1,5 versus 5,2 mg/dl, p = 0,002), tempo de antibióticos profiláticos (5,4 versus 18,4 horas, p < 0,001), tempo de latência (20,9 versus 33,6 horas, p = 0,001) e idade gestacional no parto (36,5 versus 37,2 semanas, p = 0,025). Não houve associações significativas entre os grupos e a presença de resultados perinatais adversos. A idade gestacional no diagnóstico foi o único preditor significativo de desfecho composto adverso (x2 [1] = 3,1, p = 0,0001, R2 Nagelkerke = 0,138). Conclusão: Não houve associação entre manejo ativo e expectante em gestantes com PPROM entre 34 e 36 semanas e 6 dias de gestação e resultados perinatais adversos.

Clinical Study of the Incidence of Preterm Premature Rupture of Membranes and Maternal and Fetal Outcome

Preterm premature rupture of membranes is one of the important causes of premature birth that can result in high perinatal morbidity and mortality along with maternal morbidity. The definition of premature rupture of membranes is rupture of membranes before labour and before 37 weeks of gestation is referred as Preterm PROM. If the membrane rupture is after 37 weeks of gestation, it is Term PROM. The incidence of PPROM ranges from 3 - 10 % of all deliveries and it contributes to 30 - 40 % of all preterm births. METHODSA prospective observational study of clinical analysis of the PPROM in 100 cases of 28 - 37 weeks of gestation which were delivered by caesarean section was conducted from 2018 October to 2019 September in the Department of Obstetrics and Gynaecology of Chalmeda Anand Rao Institute of Medical Sciences, Bommakal, Karimnagar. RESULTSPrevalence of PPROM in the study is 7.8 %. Intra amniotic infection was seen in 32 %. The mean latency period from rupture of membranes to delivery is 3.78 + 2.74 days. 25 % neonates were delivered by caesarean section. There was a total of 12 % perinatal deaths, still births - 4 %, 10 % - early neonatal deaths. CONCLUSIONSIn the current study, the prevalence of PPROM was 7.8 %. Careful antenatal monitoring, detection and prompt treatment of infection is necessary. Strict septic precautions, appropriate therapy, regular antenatal follow up are important factors in the prevention of PPROM. Close antenatal monitoring, identification of risk factors like cervicovaginal infection and their management play an important role in the prevention of PPROM.

Evaluation of urea and creatinine levels in vaginal wash fluid for the diagnosis of premature rupture of membranes

Background: Evaluation of urea and creatinine levels in vaginal wash fluid for the diagnosis of premature rupture of membranes.Methods: The study was conducted on150 pregnant patients, 50 in each group. Confirmed PROM and unconfirmed PROM. Per speculum examination was done to look for pooling, pH tested using the Pehanon paper and vaginal wash fluid was collected. Vaginal wash fluid urea and creatinine levels were tested by a kit based on spectrophotometry.Results: The mean urea levels were 26.35 mg/dl in the study Group 1 and 3.12 mg/dl in the control group. ROC curve was plotted and the cut off value of vaginal wash fluid urea was found to be 8.55 mg/dl. The vaginal wash fluid urea levels of >8.55 mg/dl detected PROM with a sensitivity, specificity, negative and positive predictive value of 100%. The mean creatinine levels were 0.62 mg/dl in study Group 1 and 0.20 mg/dl in the control group. ROC curve was plotted and the cut off value of vaginal wash fluid creatinine was found to be 0.405 mg/dl. Vaginal wash fluid creatinine levels detected PROM with a sensitivity of 76% and specificity of 100%. The negative predictive value and positive predictive values were 80.4% and 100%.Conclusions: Urea can be used as a definite marker of PROM and creatinine can be used as a supportive marker.

A study of maternal outcome in term premature rupture of membranes in a tertiary care hospital

Background: Premature rupture of membranes (PROM) remains a subject of great clinical relevance. The present study was conducted to study maternal morbidity and its relationship with PROM-delivery interval in patients with term PROM as compared to patients without PROM.Methods: A prospective case control study was conducted in the department of obstetrics and gynecology, Kasturba Hospital, New Delhi. 100 pregnant patients presenting to the labor room with features of PROM at term (POG>37 weeks) were taken as cases and 100 term pregnant women (age and parity matched) with intact membranes were taken as controls and compared in terms of maternal outcome.Results: This study reported maternal morbidity rate of 21% in term PROM cases which was significantly higher than in control group (5%). The major cause was febrile morbidity which occurred in 16% of cases indicating ascending infection. Other complications were abdominal and episiotomy wound infection (4%), chorioamnionitis (2%), postpartum hemorrhage (2%) and puerperal sepsis (1%). There was an increased rate of operative delivery in the case group (33%) as compared to 18% in patients without PROM. Duration of PROM-delivery interval had a significant direct proportional impact on the maternal morbidity. The duration of combined hospital stay of mother and neonate was also increased.Conclusions: Patients with term PROM have significant maternal morbidity which was mainly due to infection. The duration of the hospital stay was also significantly increased.

Retinopathy of prematurity in preterm babies in a local medical college and hospital

Background: Retinopathy of prematurity is a multifactorial vasoproliferative retinal disease that increases in incidence with decreasing gestational age and is one of the leading causes of preventable childhood blindness in India. Advances in neonatology have led to dramatic increase in survival of preterm neonates and in turn, to the risk of developing ROP. Since most of the risk factors associated with ROP mentioned above arise in the neonatal intensive care unit (NICU) itself and most of them are avoidable, cautious monitoring of the risk factors, early screening, follow up and surgical intervention have been shown to reduce the incidence and improve the outcome of ROP.Methods: This was a prospective observational study conducted for a period of 2 years. A total of 151 infants admitted in NICU /SNCU who satisfied the inclusion criteria were enrolled in this study. Initial and follow up screening was conducted in three phases the results were documented in proforma after ethical clearance.Results: Comparison of risk factors between eyes with and without ROP was done using Chi-square test. A p-value of<0.05 was considered to be statistically significant. Incidence of ROP in centre is found to be 33.8%. Among maternal risk factors, multiple gestation and PROM/PPROM is found to be significant in the development of ROP from this study. However, mode of delivery and gestational hypertension, were found to be not significant in ROP. Among neonatal risk factors, low birth weight, lower gestational age, prolonged oxygen exposure, blood transfusion, mechanical ventilation, sepsis, phototherapy was found to be significant in this study.Conclusions: ROP, being an emerging cause for potentially blinding visual disability, needs to be diagnosed early. Due to the advancements in neonatology and better survival of preterm babies, timely screening, regular follow up, early detection and intervention is mandatory. A multidisciplinary approach is required in diagnosis and treatment of the disease. Proper counselling and motivation for parents of preterm and low birth weight babies for regular follow up is also essential.
