Objectives: The aim of the study was to analyze the course of labor of grand multiparas (4 deliveries and more) in comparison to multiparas (2 or 3 deliveries).
Materials and methods: A group of 400 grand multiparas were included in the study and compared with a group of 393 multiparas. All the deliveries took place in the City Hospital in Puck in the years 1998-2002. The age of parturients, duration of pregnancy, pregnancy accompanying pathologies, course and way of delivery, indications for cesarean section, complications of labor and newborns' condition were taken into account and analyzed statistically.
Results: It occurred that grand multiparas were significantly more often countryside dwellers, experienced preterm deliveries, gained less weight during pregnancy and amniorrhexis took place in a more advanced 1st stage of labor. Perineal ruptures and episiotomies were significantly less frequent in the study group. Moreover, grand multiparas preferred traditional form of labor, more rarely deciding on water labor, despite its common access. There were no differences as to the duration of labor stages, accompanying pathologies, the use of oxytocin, postpartum curettage and newborns' condition.
Conclusions: Grand multiparity seems not to be an independent risk factor of obstetrical complications and should not be considered dangerous in centers with well organized modern perinatal care.
