title: [Induced and spontaneous labor: its duration and hourly frequency].
abstract: A retrospective randomized paired study was performed of 200 electively induced labor by means of artificial rupture of membranes and oxytocin infusion and 200 spontaneous labor. It was found that labor length was significantly shorter (p < 0.5) in the study group tan the control group (2.02 +/- 3 h and 6.2 +/- 3 h respectively). Delivery was accomplished in the majority of the induced group (50.2%) between 12:00 and 17:59 h (p < 0.001), while in the control group it occurred randomly during the 24 hours (p > 0.05).
