<P> Some of these efforts are: emphasizing a long latent phase of labor is not abnormal and not a justification for C - section; a new definition of the start of active labor from a cervical dilatation of 4 cm to a dilatation of 6 cm; and allowing at least 2 hours of pushing for women who have previously given birth and 3 hours of pushing for women who have not previously given birth before labor arrest is considered . Physical exercise during pregnancy also decreases the risk . </P> <P> Adverse outcomes in low risk pregnancies occur in 8.6% of vaginal deliveries and 9.2% of caesarean section deliveries . </P> <P> In those who are low risk, the risk of death for caesarean sections is 13 per 100,000 and for vaginal birth 3.5 per 100,000 in the developed world . The United Kingdom National Health Service gives the risk of death for the mother as three times that of a vaginal birth but it is important to remember the actual risk of death in either situation is extremely small in resource - rich settings . </P> <P> In Canada the difference in serious morbidity or mortality for the mother (e.g. cardiac arrest, wound hematoma, or hysterectomy) was 1.8 additional cases per 100 or three times the risk . </P>
