[Analysis of potential for research on giving birth in an upright position in German hospitals]

Health problem: In German hospitals, three quarters of all low-risk pregnant women give birth in the supine position, despite the fact that German, British and WHO guidelines do not recommend a supine birthing position which is associated with a higher risk to the health of both mother and fetus.

Corpus of evidence: Based on 22 RCTs with 7,280 participants, a systematic Cochrane review (Gupta et al., 2012) revealed that an upright position - compared with a supine or lithotomy position - (1) has a positive impact on fetal heart rate patterns, (2) reduces the requirement for analgesic or anaesthetic medications in the second stage of labour, and (3) results in fewer episiotomies and (4) fewer instrumental deliveries. There is a lack of evidence regarding perceived maternal autonomy, self-efficacy and anxiety when giving birth. Furthermore, evidence on long-term effects is absent. Some studies indicate that the choice of an upright birthing position might be boosted by a supporting physical and social environment and by specially trained midwives.

Implication for research: There is a need for a feasibility study and a subsequent cluster RCT in the German healthcare context in order to investigate the effects of the upright posture for birthing on perceived maternal autonomy, self-efficacy and anxiety, on the reduction of perinatal complications and on long-term complaints. The complex experimental intervention consists of (1) evidence-based and user-friendly information for women and their partners, (2) facilitating the choice for an upright labour position by special training for midwives and (3) providing a supportive physical and social environment. Within the first study phase, the exploration of feasibility in terms of access to the target group and acceptance of the intervention by pregnant women, their partners and midwives is recommended. Thereby, the implementation of guidelines for upright labour and birth, the documentation and collection of outcome and cost data could be evaluated. Non-German instruments for measuring benefits, harms and long-term effects could be adapted to and validated for the German context.
