Stages of labor

  • 1st stage: Onset of labor to dilatation of cervix

– 6-20 hours in primigravida

– 2-10 hours in multigravida

  • 2nd stage: From full dilatation of cervix to complete birth of baby
  • 3rd stage: Birth of infant to delivery of placenta

Q. 4

Q. 4

Which of the following is seen in 2nd stage of labor:

September 2005

 A

Expulsion of the fetus

 B

Increase in contraction

 C

Cervical dilatation

 D

All of the above

Ans. D

Explanation:

Ans. D: All of the above

Second stage (expulsion) begins when the cervix is fully dilated, and ends when the baby is finally born.

At the beginning of the normal second stage, the head is fully engaged in the pelvis; the widest diameter of the head has successfully passed through the pelvic brim. Ideally it has successfully also passed below the interspinous diameter. This is the narrowest part of the pelvis.

The volume of the uterine cavity is reduced and uterine contractions and retraction becomes stronger.
