Phases of second stage labor. Four descriptive case studies

Area of Science:

• Obstetrics and Gynecology
• Maternal-Fetal Medicine
• Nursing Science

Background:

• The second stage of labor, a critical period from full cervical dilation to birth, has gained attention for its distinct behavioral phases.
• Previous observations suggest identifiable behavioral characteristics within this stage.

Observation:

• A descriptive case study design was employed, videotaping four nulliparous women during spontaneous labor.
• Data collection included videotapes, narrative transcripts, and uterine monitoring from complete dilation until delivery.

Findings:

• Analysis revealed distinct behavioral changes throughout the second stage of labor.
• These changes support the division of the second stage into three identifiable behavioral phases.
• These phases offer a pattern for recognizing normal labor progression.

Implications:

• The identified behavioral phases can aid nurses and midwives in assessing labor progress.
• This framework may help in identifying deviations from a typical labor pattern.
• Enhanced understanding of labor behaviors can improve clinical monitoring and patient care.
