About this trial

This randomized clinical trial aims to compare the effect of the left lateral decubitus position versus the supine position on the duration of the active phase of labor in nulliparous women. A total of 188 participants will be randomly assigned to one of two groups. The intervention group will be placed in the left lateral decubitus position, while the control group will remain in the supine position. Both positions will be maintained for 30-minute intervals with 5-minute rest periods, continuing until delivery. The primary outcome is the duration of the active phase of labor. Secondary outcomes include rates of cesarean section, use of oxytocin and analgesics, and maternal and neonatal complications.

Trial design

Design model

Parallel

Treatments tested in this trial

  • Left Lateral Decubitus Group

    Other intervention

    Participants will be placed in the left lateral decubitus position for periods of 30 minutes, interspersed with 5-minute rest periods. This cycle will continue throughout the active phase of labor until delivery.

  • Supine Position Group

    Other intervention

    Participants will remain in the supine position for periods of 30 minutes, interspersed with 5-minute rest periods. This cycle will continue throughout the active phase of labor until delivery.

Trial outcomes

Primary outcomes

1

Duration of the active phase of labor.

The primary objective is to measure and compare the time taken to progress from the active phase to delivery between the two positioning groups.

Time frame
Time (in minutes) from the diagnosis of the active phase of labor (cervical dilation ≥6 cm) to delivery of the newborn. Within the first 24 hours after diagnosis of active phase.

Secondary outcomes

1

Incidence of Cesarean Delivery

The proportion of participants in each group who undergo a cesarean section.

Time frame
From randomization until delivery (anticipated within 48 hours per participant).
2

Use of Oxytocin for labor augmentation/conduction.

The proportion of participants in each group who receive oxytocin infusion.

Time frame
From randomization until delivery.
3

Incidence of maternal complications (e.g., perineal tears, hemorrhage, hypotension).

Composite of adverse maternal outcomes recorded during labor and the immediate postpartum period.

Time frame
From randomization until hospital discharge (approximately 24-48 hours postpartum).
4

Neonatal status as measured by Apgar score.

The Apgar score (0-10) will be recorded and compared between groups.

Time frame
At 1 minute and 5 minutes after birth.
