Maternal positioning to correct occiput posterior fetal position during the first stage of labour: a randomised controlled trial.

OBJECTIVE: To evaluate the efficacy of the hands and knees position during the first stage of labour to facilitate the rotation of the fetal head to the occiput anterior position. DESIGN: Randomised controlled trial. SETTING: Geneva University Hospitals, Switzerland. POPULATION: A total of 439 women with a fetus in the occiput posterior position during the first stage of labour. METHODS: The women in the intervention group were invited to take a hands and knees position for at least for 10 minutes. Women allocated to the control group received the usual care. For both groups, 15 minutes after randomisation, women completed a short questionnaire to report their perceived pain and the comfort of their position. MAIN OUTCOME MEASURES: The rotation of the fetal head in occiput anterior position confirmed by ultrasonography 1 hour after randomisation. RESULTS: One hour after the randomisation, 35 of 203 (17%) fetuses were diagnosed as being in the occiput anterior position in the intervention group compared with 24 of 209 (12%) in the control group. This difference was not statistically significant (relative risk 1.50; 95% CI 0.93-2.43; P = 0.13). The change in the evaluation of comfort between the randomisation and 15 minutes after showed an improvement in 70 and 39 women, no change in 82 and 78 women and a decrease in 56 and 86 women in the intervention and control groups, respectively (P = 0.02). CONCLUSIONS: This study could not demonstrate a benefit of the hands and knees position to correct the occiput posterior position of the fetus during the first stage of labour, but the women reported an increase in their comfort level. TWEETABLE ABSTRACT: Hands and knees position does not facilitate rotation into occiput anterior but increases the comfort level of women.

[Maternal postures and epidural analgesia during labour]. / Postures maternelles pendant le travail: description et interférence avec l'analgésie péridurale.

The evolution of birth is of interest for obstetricians and midwives. Postures with asymmetric stretching and balance, kneeling, or sitting have been claimed to be able to help foetal head rotation. Although walking during labour have no influence on the outcome of labour, hip-flexed postures enlarging the pelvic diameter are yet evaluated to improve the obstetric course of labour. In a prospective randomised study including 93 parturients, we compared the supine 30 degrees lateral tilt (control group) to three hip-flexed postures: sitting (S), right hip-flexed left lateral position (L) and left hip-flexed right lateral position (R). Epidural analgesia with 12 ml ropivacaine 0.1% and sufentanil 0.5 microg/ml was administered over a period of six minutes. The total epidural spread was 15+/-0.3 dermatomes and the upper level of thermo-analgesic blockade reached T7-T8 (T5 to T10) in each group. There were no differences between groups for the left and right total spread and upper level of epidural blockade, for the time to maximal block and pain relief. There was no motor block and no maternal or foetal side effects. We conclude that, for the three hip-flexed postures tested, position does not influence local anesthetic spread or symmetry of analgesia after induction of obstetric epidural anaesthesia.
