An interventional study of Positioned group in Labor; Prolonged, Second Stage and Delivery Problem, sponsored by Biruni University. Completed. Open to female participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2025-04-17.
Sponsored by Biruni University · Not applicable, Interventional, and Supportive care
This is a randomized controlled experimental study to determine the effect of maternal position on the progression of labour in deliveries in which the foetus is in the occiput posterior position.
The study included 148 gravidas admitted to a private Istanbul hospital, who consented to participate. They were divided into intervention and control groups (n=72). The intervention group assumed a side-lying position on the occiput side for 20 minutes, a prostrate position for 15 minutes, then leaned towards the bed's head for 10 minutes (rest), followed by another 20-minute side-lying position. The control group received routine delivery care.
This is a randomized controlled experimental study. The research was carried out in a private hospital in Istanbul. The population of the study covered gravidas who were admitted to the hospital for delivery with the foetus in the occiput posterior position in labour. The sample of the study included 148 volunteering gravidas, who were divided into intervention and control groups.
Research Hypotheses:
H1: In deliveries where the foetus is in the occiput posterior position, the positions given to the mother help the foetus to rotate to the occiput anterior position.
H2: Positions given to the mother in the occiput posterior position do not affect the Apgar score.
H3: In deliveries where the foetus is in the occiput posterior position, the positions given to the mother reduce the rate of interventional delivery.
Implementation :
After the occiput posterior position was established by ultrasonography, the gravidas included in the study were randomized into 2 groups as intervention and control groups. The intervention group was given the following positions during labour:
After 1 hour, the gravida was placed in a side lying position on the side of the occiput. Digital vaginal examination was repeated at 2 hour intervals. If the foetus has rotated to the occiput anterior position, the women was released (could walk, stand, allowed to do as she pleased). If the occiput posterior continued but the descent of the head was progressing, she was tilted to the side of the occiput on the delivery table after the dilatation is completed and instructed to push (keeping the upper leg up). At the time of coronation, she was laid on her back and delivered. If there was no head descent or rotation according to the digital vaginal examination finding, time was allowed for dilatation to reach 7-8 cm in the primiparae. Caeserean section (C/S) was scheduled if there was no change. If the posh was not open in multiparous patients and the head was at -3 -2, amniotomy was performed and time was allowed until dilatation was complete. However, C/S was planned if digital vaginal examination performed with an interval of 2 hours did not indicate progress.
The control group was followed up in the routine delivery room, and no positioning was done.

Ran from Feb 2015 to primary completion in Dec 2016, 22 months.
Of 18 interventional studies with no phase under Dystocia, half reached primary completion within 23 months of starting (the median), counting those still running; a quarter within 18 and three quarters within 40. This study's 22 months is close to that.
