This document provides information on the second stage of labour, including its definition, duration, phases, physiology, management, and the cardinal movements involved in normal delivery. Key points include:
- The second stage begins with full cervical dilation and ends with birth of the baby. It typically lasts 2 hours for primiparous women and 30 minutes for multiparous women.
- It involves three phases: latent, active, and transition. Important physiological changes include uterine contraction, soft tissue displacement, and fetal rotation and extension.
- Management includes monitoring the woman's pushing efforts, positioning, preparing for delivery, and potentially applying controlled traction during crowning. Spontaneous delivery of the head is preferred over techniques like
