Comparison of balloon catheter and oral misoprostol for cervical ripening in women with pre-labor rupture of membranes: A Finnish randomized controlled trial.

Introduction: Pre-labor rupture of membranes (PROM) occurs in about 8% of term pregnancies with over 70% delivering spontaneously within 24 h. However, prolonged PROM increases the risk of chorioamnionitis and neonatal sepsis. While misoprostol and oxytocin are considered safe and effective methods of labor induction, most guidelines do not encourage balloon catheter (BC) use following PROM given concerns about increased risk of chorioamnionitis.

Comparison of balloon catheter, oral misoprostol, or combination of both for cervical ripening in late-term and post-term nulliparous women: A Finnish randomized controlled multicenter pilot trial.

Introduction: Nulliparous women beyond term have high rates of induction failure. The aim of this study was to compare delivery outcomes for balloon catheter, misoprostol, and combination of both in nulliparous late- and post-term women with unfavorable cervices. We intended to explore whether the combination strategy has lower cesarean section rate and is as safe as either method alone.

Labor induction at 41 gestational weeks or expectant management for the nulliparous woman: The Finnish randomized controlled multicenter trial.

Introduction: Neonatal and maternal risks increase in term pregnancy as gestational age advances and become increasingly evident post-term. Management practices of late- and post-term pregnancies vary, and the optimal time point for intervention by labor induction is yet to be determined.

Material And Methods: This randomized controlled trial of 381 nulliparous women with unripe cervices compared labor induction at 41 gestational weeks (early induction) with expectant management and labor induction at 41 to 42 gestational weeks (expectant management).

Women's subjective perceptions and background factors associated with poor maternal childbirth experience among induced and spontaneous onset of labour: a two-year tertiary hospital cohort study.

Background: Women undergoing induction of labour (IOL) more often have poor childbirth experience compared to women with spontaneous onset of labour (SOL). For understanding and optimizing childbirth experience in IOL, we investigated the subjective maternal reasons and perceptions leading to poor childbirth experience in IOL compared to SOL, as well as the background factors and delivery outcomes associated with the poor experience.

Methods: Two-year retrospective cohort study included 836/19442 deliveries (4.

Childbirth experience in induced labor: A prospective study using a validated childbirth experience questionnaire (CEQ) with a focus on the first birth.

Objective: First birth and labor induction are risk factors for negative childbirth experiences. As labor inductions are increasing, research into this high-risk group's childbirth experiences is important. We aimed to investigate whether nulliparity or factors related to labor induction, labor, and delivery explain the association.

Comparison of primiparous women's childbirth experience in labor induction with cervical ripening by balloon catheter or oral misoprostol - a prospective study using a validated childbirth experience questionnaire (CEQ) and visual analogue scale (VAS).

Introduction: Primiparity and labor induction, especially when cervical ripening is required, are risk factors for a negative childbirth experience. Our aim was to compare childbirth experience in primiparous women with cervical ripening by balloon catheter or oral misoprostol using the validated Childbirth Experience Questionnaire (CEQ). We also wanted to compare assessment of a negative childbirth experience by visual analogue scale (VAS) and CEQ.

Breaking the myth: the association between the increasing incidence of labour induction and the rate of caesarean delivery in Finland - a nationwide Medical Birth Register study.

Objectives: To determine the association between the rate of labour induction and caesarean delivery.

Design: Medical Birth Register-based study. We used data from the nationwide Medical Birth Register collecting data on delivery outcomes on all births from 22+0 weeks and/or birth weight of at least 500 g.

Comparison of delivery outcomes in low-dose and high-dose oxytocin regimens for induction of labor following cervical ripening with a balloon catheter: A retrospective observational cohort study.

A variety of oxytocin regimens are used for labor induction and augmentation. Considering the increasing rates of labor induction, it is important to assess the most optimal oxytocin regimen without compromising maternal and fetal safety. The aim of this study was to compare delivery outcomes of low-dose and high-dose oxytocin induction protocols.

Planned vaginal and planned cesarean delivery outcomes in pregnancies complicated with pregestational type 1 diabetes - A three-year academic tertiary hospital cohort study.

Background: Finland has the world's highest incidence of 62.5/100000 of diabetes mellitus type 1 (DM1) with approximately 400 (1%) DM1 pregnancies annually. Pregnancies complicated by DM1 are accompanied with increased risk for perinatal morbidity and mortality.

Vaginal streptococcus B colonization is not associated with increased infectious morbidity in labor induction.

Introduction: Labor induction rates are increasing and, in Finland today, one of three labors is induced. Group B streptococcus (GBS) is a bacterium found in 10%-30% of pregnant women and it can be transmitted to the neonate during vaginal delivery. Although GBS is rarely harmful in the general population, it is the leading cause of severe neonatal infections such as sepsis, pneumonia, and meningitis.

Maternal childbirth experience in induced and spontaneous labour measured in a visual analog scale and the factors influencing it; a two-year cohort study.

Background: Poor maternal childbirth experience plays a role in family planning and subsequent pregnancies. The aim of this study was to compare childbirth experiences in induced and spontaneous labor and to investigate the factors influencing the childbirth experience.

Methods: This two-year cohort study included all women with term singleton pregnancies in cephalic presentation aiming for vaginal delivery at Helsinki University Hospital between January 2017 and December 2018.

Balloon catheter use for cervical ripening in women with term pre-labor rupture of membranes: A 5-year cohort study.

Introduction: To investigate the safety of balloon catheter for cervical ripening in women with term pre-labor rupture of membranes (PROM) and to compare the incidence of maternal and neonatal infections in women with PROM and women with intact membranes undergoing cervical ripening with a balloon catheter.

Material And Methods: This retrospective cohort study of 1923 women with term singleton pregnancy and an unfavorable cervix undergoing cervical ripening with a balloon catheter was conducted in Helsinki University Hospital between January 2014 and December 2018. For each case of PROM, two controls were assigned.

Success of trial of labor in women with a history of previous cesarean section for failed labor induction or labor dystocia: a retrospective cohort study.

Background: The rates of cesarean section (CS) are increasing worldwide leading to an increased risk for maternal and neonatal complications in the subsequent pregnancy and labor. Previous studies have demonstrated that successful trial of labor after cesarean (TOLAC) is associated with the least maternal morbidity, but the risks of unsuccessful TOLAC exceed the risks of scheduled repeat CS. However, prediction of successful TOLAC is difficult, and only limited data on TOLAC in women with previous failed labor induction or labor dystocia exists.

The efficacy of misoprostol vaginal insert compared with oral misoprostol in the induction of labor of nulliparous women: A randomized national multicenter trial.

Introduction: Our objective was to compare the efficacy of a 200-μg misoprostol vaginal insert vs oral misoprostol regarding the cesarean section rate and the time interval to vaginal delivery in nulliparous women with unfavorable cervix.

Material And Methods: In this prospective multicenter trial, 283 nulliparous women at term with Bishop score <6 were randomized to induction of labor with either a misoprostol vaginal insert (n = 140) or oral misoprostol (n = 143). In the oral misoprostol group, a 50-μg dose of oral misoprostol was administered every 4 hours up to three times during the first day; during the second day, the dose was increased to 100-μg every 4 hours up to three times during the first day, if necessary.

Cervical and Amniotic Fluid Matrix Metalloproteinase-8 and Interleukin-6 Concentrations in Preterm Pregnancies with or without Preterm Premature Rupture of Membranes.

Introduction: Intra-amniotic inflammation is defined by elevated inflammatory biomarkers in the amniotic fluid (AF), either due to microbial invasion of the amniotic cavity (MIAC) or sterile inflammation. Amniocentesis being an invasive procedure, we wanted to investigate whether elevated matrix metalloproteinase-8 (MMP-8) or interleukin-6 (IL-6) concentrations could be detected from cervical fluid samples.

Materials And Methods: This prospective study included 67 women with singleton nondiabetic pregnancies with or without preterm premature rupture of membranes (PPROM) between 22+0 and 37+0 weeks of gestation.

Cervical biomarkers as predictors of successful induction of labour by Foley catheter.

The prediction of successful labour induction is difficult, indicating a need for a biomarker test. Little is known about the effect of Foley catheter (FC) induction on biochemical mediators in the cervix, such as the insulin-like growth factor binding protein-1 (IGFBP-1), matrix metalloproteinases (MMP) and their inhibitors (TIMP). We enrolled 35 nulliparous women with singleton pregnancies, intact amniotic membranes and cephalic presentation ≥40 gestational weeks scheduled for labour induction by FC.

Foley Catheter or Oral Misoprostol for Induction of Labor in Women with Term Premature Rupture of Membranes: A Randomized Multicenter Trial.

Objectives To compare the Foley catheter and misoprostol for induction of labor in term women with premature rupture of membranes. Study Design A randomized controlled trial was performed in three university hospitals in Finland between March 2012 and September 2014. A total of 202 term women with ruptured membranes >18 hours, singleton pregnancies in cephalic presentation, unfavorable cervix, and no prior cesarean section were enrolled.
