RESUMO
INTRODUCTION: In clinical experience, occiput posterior (OP) position is associated with longer labor duration than occiput anterior (OA) position, but few studies have investigated the association between labor duration and fetal position. We aimed to compare duration of the active phase of labor in OP deliveries with OA deliveries in a contemporary population using survival methods. Secondary aims were to compare the frequencies of operative interventions, obstetric anal sphincter injuries (OASIS), postpartum hemorrhage, and newborn outcomes in OP with OA deliveries. MATERIAL AND METHODS: We did a historical cohort study in three university hospitals in Norway from 2012 to 2022. Women with a single fetus in cephalic presentation, no previous cesarean section and gestational age ≥37 weeks were eligible and stratified into the first four groups of the Robson ten-group classification system (TGCS). We estimated the mean duration and calculated the hazard ratio (HR) for delivery using survival analyses. Cesarean sections and instrumental vaginal deliveries were censored. RESULTS: The study population comprised 112 019 women, 105 571 (94.2%) were delivered in OA and 6448 (5.8%) in OP position. The estimated mean duration of the active phase of labor was longer in women with the fetus in OP position in all four TGCS groups. The estimated duration was longer in the OP groups in analyses stratified with respect to epidural analgesia and oxytocin augmentation. The graphical abstract illustrates the probability of delivery in OP compared with OA position in merged TGCS groups 1 and 2a, as a function of time. The unadjusted HR was 0.33 (95% CI 0.31-0.36) for fetuses delivered in OP position compared with OA position in TGCS group 1, 0.25 (95% CI 0.21-0.27) in group 2a, 0.70 (95% CI 0.67-0.73) in group 3, and 0.61 (95% CI 0.55-0.67) in group 4a, respectively. Neither maternal age, gestational age, BMI nor birthweight had confounding effect. Operative delivery rates and OASIS rates were higher in OP position in all four groups. CONCLUSIONS: We found longer duration of the active phase of labor in women with the fetus delivered in OP position in all four TGCS groups.
RESUMO
BACKGROUND: Seven Norwegian hospitals offer an outpatient service for women who have undergone female genital cutting (FGC). This study presents symptoms, findings and treatment in women who were examined at the outpatient clinics in the period 2004-2015. MATERIAL AND METHOD: Each hospital identified patients by searching for relevant diagnostic and procedure codes. All those who had been examined at the outpatient clinics were included. Data were retrieved from patient records. RESULTS: A total of 913 women were included. The median age at the time of undergoing FGC was seven years, and at the time of consultation, 26 years. Almost half of the women were pregnant. The majority (81 %) had FGC type III (infibulation). Of these, 87 % had gynaecological problems. Of women with types I and II FGC, 55 % and 70 %, respectively, reported gynaecological problems. Altogether 64 % received surgical treatment, primarily deinfibulation (98 %). Few complications were recorded. INTERPRETATION: In many young, non-pregnant infibulated women, FGC-related problems that can be treated with deinfibulation may have been present since childhood and adolescence. There is probably an unmet need for treatment, irrespective of the type of FGM.
