Does prolonged labor affect the birth experience and subsequent wish for cesarean section among first-time mothers? A quantitative and qualitative analysis of a survey from Norway.

BACKGROUND: Prolonged labor might contribute to a negative birth experience and influence first-time mothers' attitudes towards future pregnancies. Previous studies have not adjusted for possible confounding factors, such as operative delivery, induction and postpartum hemorrhage. We aimed to determine the impact of prolonged labor on birth experience and a wish for cesarean section in subsequent pregnancies. METHODS: A survey including the validated "Childbirth Experience Questionnaire". First-time mothers giving birth between 2012 and 2014 at a Norwegian university hospital participated. Data from deliveries were collected. Regression analysis and thematic content analysis were performed. RESULTS: 459 (71%) women responded. Women with labor duration > 12 h had significantly lower scores on two out of four sub-items of the questionnaire: own capacity (p = 0.040) and perceived safety (p = 0.023). Other factors contributing to a negative experience were: Cesarean section vs vaginal birth: own capacity (p = 0.001) and perceived safety (p = 0.007). Operative vaginal vs spontaneous birth: own capacity (p = 0.001), perceived safety (p < 0.001) and participation (p = 0.047). Induced vs spontaneous start: own capacity (p = 0.039) and participation (p = 0.050). Postpartum hemorrhage ≥500 ml vs < 500 ml: perceived safety (p = 0.002) and participation (p = 0.031). In the unadjusted analysis, prolonged labor more than doubled the risk (odds ratio (OR) 2.66, 95%CI 1.42-4.99) of a subsequent wish for cesarean delivery. However, when adjustments were made for mode of delivery and induction, emergency cesarean section (OR 8.86,95%CI 3.85-20.41) and operative vaginal delivery (OR 3.05, 95%CI 1.46-6.38) remained the only factors significantly increasing the probability of wanting a cesarean section in subsequent pregnancies. The written comments on prolonged labor (n = 46) indicated four main themes: Difficulties gaining access to the labor ward. Being left alone during the unexpectedly long, painful early stage of labor. Stressful operative deliveries and worse pain than imagined. Lack of support and too little or contradictory information from the staff. CONCLUSIONS: Women with prolonged labors are at risk of a negative birth experience. Prolonged labor per se did not predict a wish for a cesarean section in a subsequent pregnancy. However, women with long labors more often experience operative delivery, which is a risk factor of a later wish for a cesarean section.

De-medicalization of birth by reducing the use of oxytocin for augmentation among first-time mothers - a prospective intervention study.

BACKGROUND: The use of synthetic oxytocin for augmentation of labor is rapidly increasing worldwide. Hyper-stimulation is the most significant side effect, which may cause fetal distress and operative delivery. We performed an intervention consisting of an educational program and modified guidelines to achieve a more appropriate use of oxytocin. METHODS: This prospective intervention study included 431 first-time mothers at term with spontaneous onset of labor before (October 2012 to May 2013), and 664 after the intervention (April 2014 to April 2015). Our outcomes were prevalence and duration of oxytocin treatment, mode of delivery, indication for operative delivery, episiotomy, anal sphincter tears, bleeding, labor duration, pain relief and the effect of oxytocin on mode of delivery. RESULTS: After the intervention, 52.9% were diagnosed with dystocia, compared with 68.9% before (p < 0.001). Oxytocin was not always used in accordance with the guidelines, but a significant reduction in oxytocin rates from 63.3% to 54.1% (p < 0.001) was obtained. More women without dystocia according to the existing guidelines were augmented after the intervention (18.9% vs 8.4%, p < 0.001). Assessing all labors, the median duration of oxytocin treatment was reduced by 72% (from 90 to 25 min) without increasing the median duration of labor (385 min in both groups). There was a moderate reduction in operative vaginal deliveries from 26.9 to 21.5% (p = 0.04), and dystocia as an indication for these deliveries increased (p = 0.01). There was a moderate increase in caesarean sections from 6.7 to 10.2% (p = 0.05), but no increase in dystocia as an indication for these deliveries. Women receiving oxytocin were more likely to have an operative vaginal birth, even after adjusting for birth weight, epidural analgesia and labor duration, OR: 2.1 (CI 1.1-4.0) before and OR 2.7 (CI 1.6-4.5) after the intervention. CONCLUSIONS: Our intervention led to a significant reduction in the use of oxytocin. However, more than half of the women remained diagnosed with dystocia. Operative vaginal births seem to be associated with oxytocin treatment. Therefore, augmentation with oxytocin should be used with caution and only when medically indicated. Even more modified guidelines for augmentation than the ones applied in this study might be appropriate.
