Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
A total of 160 nulliparous term pregnant women undergoing labor induction were randomly assigned to one of three treatment groups using computer generated random number table: 50 mg meperidine in group 1 (n=53) and 16 mg valethamate bromide in group 2 (n=53) as the treatment groups. All medications were given just once time by slow intravenous infusion in about 2 minutes when cervical dilation was about 4-6 cm and the fetal head was well applying. Patient and the doctor who followed the stages of labor were blind to the medication.
Intervention code [1] 3967 0
Treatment: Drugs
Comparator / control treatment
Group 3 served as control group and consisted of 53 women who were given normal saline (0.9 % NaCl) as placebo. The medication was given just once time by slow intravenous infusion in about 2 minutes using injectors containing 10 mL solution (normal saline plus related group’s drug) when fetal head was well applying and uterine contractions were well-established, and cervical dilatation was between 4 and 6 cm. Patient and the doctor who followed the stages of labor were blind to the medication.
Control group
Placebo

Timepoint [1] 5347 0
from the time of beginning of the intervention to the time of the expulsion of the fetus.
Secondary outcome [1] 8984 0
maternal adverse effects, monitored by the author who was blind to the medication.
Timepoint [1] 8984 0
Monitored constantly throughout the birth after the allocated treatment has been injected into the participant.
Secondary outcome [2] 8985 0
fetal adverse effects, monitored by the author who was blind to the medication.
Timepoint [2] 8985 0
Immediately after delivery .

Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Group allocation was predetermined and placed in consecutively numbered opaque, sealed envelopes. The next consecutive envelope was drawn after the patient consented to randomization.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomization was performed with use of a computer generated random number table.
Masking / blinding
Blinded (masking used)
