Birth Process

  • Introduction to Birth

    • Focus on understanding the birth process and its various stages.

    • Discussion on assessing newborns and issues related to preterm and low birth weight infants.

Learning Objectives

  • Describe the Birth Process: Understand the three stages of labor and delivery.

  • Assessing Newborns: Familiarize with various assessment scales (e.g., Apgar scale).

  • Preterm and Low Birth Weight Infants: Characteristics and developmental implications.

Stages of Birth

1. Three Stages of Labor

  • Stage I: Uterine contractions 15-20 minutes apart, lasting up to 1 minute. This stage is the longest, taking 6-12 hours.

  • Stage II: Begins when the baby’s head moves through the cervix and ends when the baby is fully born, lasting 45 minutes to 1 hour.

  • Stage III: Afterbirth stage, involves the expulsion of the placenta, umbilical cord, and membranes, lasting only a few minutes.

2. Labor Positions

  • Various positions to assist during labor include:

    1. Standing or walking

    2. Leaning (on a partner or wall)

    3. Sitting

    4. Squatting

    5. Kneeling

    6. Side-lying

    7. Semi-sitting or semi-reclining

Birth Practices in the U.S.

  • Hospital Births: 98.5% of births occur in hospitals, with 1.5% outside, including 63% at home and 31% at birthing centers.

  • Role of Midwives: Present in 8% of hospital births; provide emotional and educational support (doula).

  • Pain Management: Options include analgesia, anesthesia, and oxytocin.

Childbirth Methods

  • Natural Childbirth: Aims to reduce pain and anxiety via education and relaxation techniques.

  • Prepared Childbirth (Lamaze Method): Emphasizes breathing to manage pushing during delivery.

  • Cesarean Delivery: Surgical method used for certain complications, with ongoing debate over benefits and risks.

Assessing Newborns

1. Apgar Scale

  • Evaluates five criteria at 1 and 5 minutes:

    1. Heart rate

    2. Respiratory effort

    3. Muscle tone

    4. Body color

    5. Reflex irritability

  • Low Scores: Linked to educational support needs, ADHD, and developmental risks.

2. Additional Assessment Tools

  • Brazelton Neonatal Behavioral Assessment Scale (NBAS): Assesses neurological development and reflexes within the first month.

  • Neonatal Intensive Care Unit Neurobehavioral Scale (NNNS): Focuses on behavior, neurological responses, and regulation.

Preterm and Low Birth Weight Infants

  • **Definitions:

    • Low Birth Weight:** <5.5 lbs; very low: <3.5 lbs; extremely low: <2 lbs.

    • Preterm Infants: Born before 37 weeks of gestation.

    • Small for Date Infants: Below normal weight for the gestational period.

1. Supporting Development

  • Kangaroo Care: Involves skin-to-skin contact to foster infants' growth and reducing stress.

  • Massage Therapy: Promotes weight gain and can lower hospital stay duration.

Discussion: Baby Naming

  • Cultural Influence: Explore how cultural and familial backgrounds create various nuances in naming conventions.

    • Key considerations about meaning, symbolism, and potential drawbacks of unique names.

Reminders

  • Participation Required: Weekly questions and memes are mandatory for participation credits.

  • Quiz Information: Open-note quiz on prenatal to early childhood topics available in Week 4.
