Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The randomization assignments were placed into opaque envelopes. Based on the obtained schedule, the number of sealed envelopes, which are equal to the required blocks, will be prepared and labeled. Each envelope contains the corresponding sealed allocation cards that will allocate treatments to patients. The people, who prepare the randomized scheme, will not involve in the trial. The allocation schedule will be concealed until the end of trial.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
After signing on the consent form, all eligible patients will be enrolled in the trial and then randomized by computer-generated randomization into two groups to receive intravenous oxytocin and intramuscular oxytocin in the management of the third stage of labor.
Masking / blinding
