Portograms of two hundred obstetrically and medically normal labouring patients were studied which included hundred primiparas and hundred multiparas. Analysis of partograms revealed that mean cervical dilatation rate for primiparas was 1.55 cm/hr, 0.91 cm/hr and 0.39 cm/hr in spontaneous, assisted and caesarean section deliveries, respectively. An initial dilatation rate (IDR) of 1 cm/hr or more resulted in 100% vaginal deliveries, while 60.5% required assisted delivery or caesarean section with an IDR of less than 1 cm/hr. In multiparous patients the IDR was 1.66 cm/hr for spontaneous deliveries. Mothers needing assisted delivery had a mean IDR of 0.93 cm/hr. All multiparas delivered spontaneously with an IDR of 1 cm/hr or more and none of them delivered without assistance when the IDR was less than 0.5 cm/hr. The principal contribution of initial dilatation rate (IDR) measurements is in reliably labeling the potential problem deliveries.
