Duration of labor
There are wide variations in the duration of labor. The length of labor is influenced by party, time of the last delivery, type of pelvis, size and presentation of the fetus, strength and frequency of uterine contractions. The greatest part of labor is taken up by the first stage. The most important thing is the progress of labor provided the woman is comfortable and the fetus is well. The labor last longer in primigravidae than in multigravidae.
Some times primigravidae spend less time while multipara spend more time in labour. Evidences have shown that the use of Oxytocin and one-to-one care has reduced the period of labour considerably.
