- BACKGROUND: The aim of this study was to compare maternal labour and birth outcomes between women who gave birth on a birth seat or in any other position for vaginal birth and further, to study the relationship between synthetic oxytocin augmentation and maternal blood loss, in a stratified sample.METHODS: A re-analysis of a randomized controlled trial in Sweden. An on-treatment analysis was used to study obstetrical outcomes for nulliparous women who gave birth on a birth seat (birth seat group) compared to birth in any other position for vaginal birth (control group). Data were collected between November 2006 and July 2009. The outcome measurements included perineal outcome, post partum blood loss, epidural analgesia, synthetic oxytocin augmentation and duration of labour.RESULTS: The major findings of this paper were that women giving birth on the birth seat had shorter duration of labour and were significantly less likely to receive synthetic oxytocin for augmentation in the second stage of labour. Significantly more women had an increased blood loss when giving birth on the birth seat, but had no difference in perineal outcomes. Blood loss was increased regardless of birth position if women had been exposed to synthetic oxytocin augmentation during the first stage of labour.CONCLUSIONS: The results of this analysis imply that women with a straightforward birth process may well benefit from giving birth on a birth seat without risk for any adverse obstetrical outcomes. However it is important to bear in mind that, women who received synthetic oxytocin during the first stage of labour may have an increased risk for greater blood loss when giving birth on a birth seat. Finally it is of vital importance to scrutinize the influence of synthetic oxytocin administered during the first stage of labour on blood loss postpartum, since excessive blood loss is a well-documented cause of maternal mortality worldwide and may cause severe maternal morbidity in high-income countries.TRIAL REGISTRATION: Unique Protocol ID: NCT01182038 ( http://register.clinicaltrials.gov).

- Abstract Background: The WHO advises against recumbent or supine position for longer periods during labour and birth and states that caregivers should encourage and support the woman to take the position in which she feels most comfortable. It has been suggested that upright positions may improve childbirth outcomes and reduce the risk for instrumental delivery; however RCTs of interventions to encourage upright positions are scarce. The aim of this study was to test, by means of a randomized controlled trial, the hypothesis that the use of a birthing seat during the second stage of labor, for healthy nulliparous women, decreases the number of instrumentally assisted births and may thus counterbalance any increase in perineal trauma and blood loss. Methods: A randomized controlled trial in Sweden where 1002 women were randomized to birth on a birth seat (experimental group) or birth in any other position (control group). Data were collected between November 2006 and July 2009. The primary outcome measurement was the number of instrumental deliveries. Secondary outcome measurements included perineal lacerations, perineal edema, maternal blood loss and hemoglobin. Analysis was by intention to treat. Results: The main findings of this study were that birth on the birth seat did not reduce the number of instrumental vaginal births, there was an increase in blood loss between 500 ml and 1000 ml in women who gave birth on the seat but no increase in bleeding over 1000 ml and no increase in perineal lacerations or perineal edema. Conclusions: The birth seat did not reduce the number of instrumental vaginal births. The study confirmed an increased blood loss 500 ml - 1000 ml but not over 1000 ml for women giving birth on the seat. Giving birth on a birth seat caused no adverse consequences for perineal outcomes and may even be protective against episiotomies. Trial registration number: ClinicalTrials.gov.ID: NCT01182038

- Background: Physical benefits are suggested for women and their babies when women adopt an upright position of their choice at birth. Available care options during labour influence women's impressions of what intrapartum care is. This indicates that choice of birth positions may be determined more by midwives than by women's preferences. Question: The aims of this study were to investigate factors associated with adherence to allocated birth position and also to investigate factors associated with decision-making for birth position. Method: An invitation to answer an on-line questionnaire was mailed. Findings: Despite being randomised, women who gave birth on the seat were statistically significantly more likely to report that they participated in decision-making and that they took the opportunity to choose their preferred birth position. They also reported statistically significantly more often than non-adherers that they felt powerful, protected and self-confident. Conclusions: Midwives should be conscious of the potential impact that birth positions have on women's birth experiences and on maternal outcomes. Midwives should encourage women's autonomy by giving unbiased information about the birth seat. An upright birth position may lead to greater childbirth satisfaction. Women's experience of and preferences for birth positions are consistent with current evidence for best practice. (C) 2013 Australian College of Midwives.
