Lecture Notes: Fetal Station

Introduction to Fetal Station

• Fetal Station Definition: Location of the baby's presenting part in the pelvis.
  • Presenting part: Closest to the exit route of the uterus.
  • Common presenting parts: Head (most common), buttocks, shoulder.

Measurement of Fetal Station

• Measured in centimeters.
• Reference Point: Ischial spine.
• Interpretation:
  • Positive Numbers: Presenting part below the ischial spine.
  • Negative Numbers: Presenting part above the ischial spine.

Finding Fetal Station

• Ischial Spine Location:
  • Left and right ischial spine.
  • Line between spines = Fetal Station Zero.

Fetal Station Scale

• Negative Numbers: Above the ischial spine.
  • Negative 1: 1 cm above the ischial spine.
  • Negative 2: 2 cm above the ischial spine.
  • Progression continues to Negative 5.
• Fetal Station Zero:
  • Landmark: Ischial spine.
  • Baby is considered "engaged" at this point.
• Positive Numbers: Below the ischial spine.
  • Positive 1: 1 cm below the ischial spine.
  • Positive 2: 2 cm below; typically when mother begins pushing.
  • Positive 4 & 5: Birth is imminent, baby likely crowning.

Memory Trick

• Positive Numbers: "I am positive I am getting this baby out today."
• Negative Numbers: Negative because the baby isn't ready to exit.

Quick Quiz

• Fetal Station at Ischial Spine: 0 cm (Baby is engaged).
• Example: If the baby's presenting part is at station +4, it is 4 cm below the ischial spine.

Conclusion

• For more information: Refer to complete mother-baby flashcards.
• Aim: Present material in a concise manner without textbook fluff.
• Encouragement for future nurses: Happy studying!
