A Phase 4 study testing hyoscine-N-butyl bromide(HBB) and Saline in people with Labor Fast, run by Sisli Hamidiye Etfal Training and Research Hospital at 1 site in Turkey (Türkiye).
Trial summary
Although Hyoscine N butyl bromide (HBB) is used liberally to facilitate cervical dilatation, there is little and inconclusive data about its efficacy. The aim of this study was to determine the efficacy and safety of HBB on the augmentation of labor.420 of total 1640 pregnant women admitted to the investigators clinic… Read more about this study

About this study
Official title: Efficacy and Safety of Hyoscine N Butyl Bromide on the Augmentation of Labor: a Double-Blind, Placebo - Controlled Trial
Although Hyoscine N butyl bromide (HBB) is used liberally to facilitate cervical dilatation, there is little and inconclusive data about its efficacy. The aim of this study was to determine the efficacy and safety of HBB on the augmentation of labor.420 of total 1640 pregnant women admitted to the investigators clinic (Sisli Ethal Training and Research Hospital, Obstetrics and Gynecology Department Obstetrics Service ) between 37-41 gestational weeks, active phase (cervical dilatation: 4 cm, cervical effacement: %50 or more) of spontaneous labor with vertex presentation enrolled to study. 382 of them were included in this study. Patients were randomized to receive intravenously(IV) either 20 mg/ml HBB or a similar amount of placebo (1 ml 0.9% NaCl) at the beginning of the active phase of labor. The medications applied as single dose. The time elapsed until the second stage of labor, second stage and third stage were measured.
Read the detailed description
The investigators aimed to study the effects and safety of 20mg intravenous HBB for the shortening of labor in both prima- and multigravid women.The study designed as a double blind, randomized, controlled trial comparing the two groups of intervention; Intravenous 20 mg (1mL) Hyoscine-N-Butylbromide (HBB) versus placebo (1mL saline) in both primigravid and multigravid women.Singleton, vertex presentation at term (gestational age range; 37-41weeks) primigravid and multigravid women without any chronic and pregnancy-induced diseases were included to the study. The investigators excluded the cases with premature rupture of membranes, preeclampsia, eclampsia, placental abruption, placenta previa, abnormal placental attachment, twin pregnancy, non- cephalic presentations, previous uterine surgery and cephalopelvic disproportion.Randomization was done by using cards .The women were allocated into two groups by using a sealed enveloped system.A yellow and a red card were placed separately in each sealed envelope. The syringes containing the drug and placebo were prepared by the investigational pharmacy staff and labeled with a yellow or red sticker on it. Each syringe contained either 1ml(20mg) of Hyoscine-N-Butylbromide (HBB) (MOLIT ampule,Adeko, Turkey) or 1 ml of normal saline solution (placebo) in which both of the liquids are colorless. The participants, nurses and doctors were all blinded to syringes. The patients were asked to pick up one envelope in order and the color of the card was corresponding to the sticker's color on the syringe.Nurses applied the selected color labeled syringe to each patient. Participants received the contents of the syringe as a single dose, given intravenously (IV).
A partogram was drawn and vaginal examinations recorded in every 2 hours.The active phase of labor was defined as 4 cm cervical dilatation and 50% cervical effacement in the presence of regular uterine contractions (2-3 contractions in every 10 minutes). The drug was given only once when the active phase was achieved. Iatrogenic amniotomy was performed for women who did not have a spontaneous rupture of membrane at the time when the cervical ripening was 8 cm. The duration of labor during the first, second and third stages, oxytocin induction, iatrogenic amniotomy, pre- and postpartum haemoglobin levels, birth weight and APGAR scores were recorded. Neonatal APGAR scores were determined 1 and 5 minutes after birth.

What is being measured
The primary outcome is the main question the study is designed to answer.
Effect of HBB on the active management of labor
The aim of the active management of labor is to shorten the duration of labor without an increase in maternal or fetal morbidity and mortality. Appropriate cervical dilatation and effacement are essential for the progression of labor. Our study designed to evaluate the effects of HBB on cervical dilatation and demonstrated the efficacy of HBB in augmenting labor. We are going to measure cervical effacement and dilation in every 2 hours to evaluate the progression of labor. To evaluate the effect of HBB on active phase of labor, we will measure the time (in minutes) between the active phase of labor and delivery.The measured time difference is going to give us 'does HBB has any effects on the shortening of active phase of labor'.
Measured: up to 7 month
Secondary outcomes (2)
Safety and efficacy of HBB on maternal outcomes
Maternal complications of drug-related side effects (nausea, vomiting, pruritus, rash, mouth establishment, collided), postpartum hemorrhage (more than 500cc), 3th or 4th degree vaginal tears, intrapartum chorioamnionitis (38 ° C higher fever, vaginal temperature increase, uterine tenderness, or Fetal heart rate above 160 to be), postpartum endometritis (first 24 hours, 38 ° C higher with fever uterine tenderness, purulent foul-smelling discharge) covers.
Measured: up to 7 month
Safety and efficacy of HBB on fetal outcomes
The 5th minute Apgar score of neonatal complications (5 Min. 7 below), feeding intolerance, neonatal jaundice, Transient tachypnea of the newborn (TTN), hypoglycemia, neonatal sepsis and intensive care unit covers the need.
Measured: up to 7 month

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Effect of HBB on the active management of labor (time frame: up to 7 month). It is what the study was designed to measure, not a finding.

Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Mar 2014.
