Which of the following abnormalities of labor is associated with a significantly increased incidence of neonatal morbidity?



A Prolonged latent phase

B Protracted descent

C Secondary arrest of dilation

D Protracted active-phase dilation

Ans. C

Secondary arrest of dilation

a. Three significant advances in the treatment of uterine dysfunction have reduced the risk of perinatal morbidity and mortality:

i. the avoidance of undue prolongation of labor;

ii. the use of intravenous oxytocin in the treatment of some patterns of uterine dysfunction; and

iii. the liberal use of cesarean section (rather than midforceps) to effect delivery when oxytocin fails.

b. Prolonged latent phase is not associated with increased risk of perinatal morbidity (PNM) or low Apgar scores and should be treated by therapeutic rest.

c. Pro traction disorders have a higher rate of PNM and low Apgar scores, but not if spontaneous labor follows the abnormality Arrest disorders are associated with significantly higher rates of PNM following either spontaneous or instrument-assisted delivery
