An interventional study of Left Lateral Decubitus Group and Supine Position Group in Labor Pain, sponsored by Universidad Nacional Autonoma de Honduras. Recruiting at 1 site in Honduras. Open to female participants aged 18 Years to 45 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-02-13.

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.
Globally, maternal positioning during labor is a key component of humanized childbirth. While the World Health Organization recommends allowing women to adopt comfortable positions, the supine position remains prevalent in many clinical settings for practitioner convenience. This study in Honduras seeks to generate local evidence on the impact of maternal position on labor progression. Nulliparous women at term (≥37 weeks) with a singleton pregnancy in cephalic presentation and in the active phase of labor (≥6 cm dilation) will be recruited from the labor and delivery unit of the Hospital Materno Infantil. After providing informed consent, participants will be randomized. The primary efficacy endpoint is the time from the onset of the active phase (or intervention start, if later) until delivery. The study hypothesizes that the left lateral position will significantly reduce active labor duration compared to the supine position, potentially reducing unnecessary surgical interventions and improving the childbirth experience.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

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.
Other: Left Lateral Decubitus Group
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.
Other: Supine Position Group
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.

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.
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).
Use of Oxytocin for labor augmentation/conduction.
The proportion of participants in each group who receive oxytocin infusion.
Time frame: From randomization until delivery.
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).
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.
Plan to share: Undecided — The research team acknowledges the importance of data sharing but has not yet established the necessary infrastructure, resources, and legal/ethical agreements required for the secure preparation, anonymization, and controlled sharing of individual participant data (IPD). Decisions regarding future sharing will depend on internal review, compliance with Honduran data protection regulations, and securing appropriate funding and technical support for long-term data stewardship.
