Control group
Active

Outcomes
Primary outcome [1] 290731 0
maternal blood loss that will be determined by calculation the difference in the postoperative and preoperative weight of surgical drapes and towels.Also, the difference between the initial hematocrit and the final hematocrit (24 h after the operation) was evaluated.

intraoperatively and also postoperative 24 hour.
Secondary outcome [1] 305107 0
unintended extension of incision evaluated as any defect beyond original incision.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
the allocation was done with sealed opaque envelopes
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Assignment to one of the two treatment groups was generated using a table of random numbers. The assigned treatment was written on a card and sealed in secure opaque envelopes numbered in sequence.

A sample size and power calculation was undertaken,
and it was determined that 425 women in each group was
sufficient power (power of 0.80, a of 0.05, and b 1/4 0.20)
to demonstrate a difference of 5% between groups.
