Duration of labor

 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.

 

Calculation of duration of labour

Example:

 

Date – 12/6/2008

 

Time:

 

Labour begins – 12:30a.m

 

OS fully dilated – 7.15a.m

 

Baby delivered – 7.25am.

 

Placenta & membranes delivered – 7.38a.m 1st Stage: 12.30 – 7.15a.m = 6hrs : 45mins

2ndStage : 7.15 – 7.25a.m = 10mins

3rd Stage: 7.25 – 7.33a.m = 8mins

TOTAL = 7hrs: 3mins
