Stages/Mechanisms of labor and Labor pains

Chin is brought into closer contact with fetal chest

Flexion
Biparietal diameter of the head passes the pelvic outlet

Engagement
The head is born with this mechanism

Extension
Head rotates briefly to the position it occupied when it was engaged in the outlet

Restitution
Descent depends on these four forces
- Pressure amniotic fluid
- Direct pressure of contracting fundus
- Contraction of maternal diaphragm and abdominal muscles
- Extension and straightening of the fetal body
This is the longest stage

First Stage
This stage is when homeostasis is established

Fourth Stage
The three phases of the second stage of labor
- Latent
- Descent
- Transition
The three phases of the first stage of labor
- Latent
- Active
- Transition
this risk increases as the length of the third stage increases

- Efflurage
- Breathing
- Hypnosis
Pain in the first stage of labor is caused by this

Cervical stretching
