3. Protracted Labour

“…Following these criteria it will be found that, in the series here discussed, the number of prolonged labours probably caused by the prolonged duration of the second stage, is very limited. On the other hand, the duration of the third stage is, as a rule so short (in parturients between the ages of 20 and 24 years, 16.8 minutes, according to RITALA (13), and in elderly primiparas, 16.4 minutes, according to VARA (14)) that its consideration, apart from facilitating the collection of cases, would not have significantly affected the results which have been assessed using the accepted 6-hour periods. Besides, the estimation of the duration of labour is based on the information given by the patients.…”

“…With the prolongation of labour, this difference disappears. In view of the fact that lo, the full duration of labour initiated by irregular pains is about one and a half times longer than that of the labours initiated by regular pains, 2' the duration of the period of irregular pains is definitely longer than that of the regular pains (RITALA (13): in primiparas: 15 hours, 06 minutes, and 11 hours, 46 minutes; in secundiparas: 11 hours, 1 2 minutes, and 6 hours, 15 minutes), it was considered justified, in estimating the durations of the labours in this series, also to count the elapsed time from the first irregular pains to the end of the third stage (Table 3). This table-shows also the duration in the group dabour initated by premature rupture of the membranes)) which were estimated from the moment when the membranes ruptured.…”
