“…14 However a recent survey from the Netherlands answered by 1154 women reported that 58.9 % preferred supine positions, 19.6 % preferred non-supine positions and 21.5 % had no distinct preference. 15 Midwives' personal attitudes and own physical capacity were shown, to some extent, to have an impact on the adherence-rate in an RCT by Thies-Lagergren et al 16 and other researchers have also suggested that midwives have an impact on women's birth position. 1, 7 Non-adherence in intrapartum studies is a problem that has been discussed in a study by Hundley and Cheyne.…”

“…The present article is based on data collected in an RCT by Thies-Lagergren et al [9,11] and is a re-analysis of the following outcomes; synthetic oxytocin for augmentation of labour, perineal outcomes (episiotomies/lacerations/oedema), postpartum blood loss, duration of labour. An additional analysis regarding use of epidural analgesia was carried out.…”

“…A secondary analysis, also carried out according to the ITT principal, was performed to assess whether birth on the birth seat affected the use of synthetic oxytocin for augmentation of the second stage of labour, duration of labour and infant outcomes. The main findings of that analysis were that women allocated to the birth seat had a significantly shorter second stage of labour despite similar numbers of women who received synthetic oxytocin augmentation in both groups and that neonatal outcomes did not differ between the groups [11]. …”

“…Analysis according to the received treatment or “on-treatment” (OT) analysis is carried out without regard to the initial randomization and may be considered as a complement to ITT analysis when non-compliance is substantial, however with an increased risk for selection bias [18]. There was considerable non-compliance (49.5%) to randomization in the RCT by Thies-Lagergren et al [9,11] and it is important to attempt to understand if the results, which showed a shortened second stage of labour and increased blood loss were associated with the use of the birth seat per se. Therefore, the present article is in response to colleagues’, researchers’ and reviewers’ questions about how the results of the maternal outcomes in the two ITT analyses [9,11] might be, if analysis was carried out according to how women actually gave birth (OT).…”

BackgroundThe 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.MethodsA 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.ResultsThe 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.ConclusionsThe 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 registrationUnique Protocol ID: NCT01182038 ( http://register.clinicaltrials.gov)
