Decoding Labor and Delivery: Essential Terms and Abbreviations

This article aims to provide clarity and understanding, helping you navigate the complexities of childbirth with greater ease. We'll explore various terms related to pregnancy, labor, delivery, and postpartum care, along with their corresponding abbreviations.

Pregnancy-Related Terms and Abbreviations

• EDD (Estimated Due Date): The approximate date when your baby is expected to be born. It's calculated based on the first day of your last menstrual period (LMP).
• LMP (Last Menstrual Period): The first day of your last menstrual period, used to calculate the EDD.
• Gestational Age: The age of the pregnancy, measured in weeks from the first day of the LMP.
• Gravida/Para (G/P):
  • Gravida (G): The total number of pregnancies a woman has had, regardless of outcome.
  • Para (P): The number of pregnancies that have resulted in a birth after 20 weeks of gestation. Para is often followed by four numbers (TPAL):
    • T (Term): Number of term births (37 weeks or later).
    • P (Preterm): Number of preterm births (between 20 and 37 weeks).
    • A (Abortions): Number of pregnancies ending in abortion (spontaneous or induced) before 20 weeks.
    • L (Living): Number of living children.
  • Example: G3P1112 means the woman has been pregnant three times, has one term birth, one preterm birth, one abortion, and two living children.

• Amniotic Fluid: The fluid surrounding the baby in the uterus.
• Placenta: The organ that provides oxygen and nutrients to the baby and removes waste products.

Labor and Delivery Terms and Abbreviations

• Labor: The process of childbirth, from the first contractions to the delivery of the baby and placenta.
• Contraction: The tightening and relaxing of the uterine muscles, which helps to dilate the cervix and push the baby down the birth canal.
• Cervix: The lower part of the uterus that opens into the vagina.
• Dilation: The opening of the cervix, measured in centimeters (cm) from 0 to 10 cm. 10 cm is considered fully dilated.

• Station: The position of the baby's head in relation to the ischial spines (bony prominences in the pelvis). Station is measured from -3 to +3. 0 station means the baby's head is at the level of the ischial spines.
• Engagement: When the baby's head has descended into the pelvis and is at 0 station.
• SROM (Spontaneous Rupture of Membranes): The amniotic sac ruptures on its own.
• AROM (Artificial Rupture of Membranes): The amniotic sac is intentionally ruptured by a healthcare provider to induce or augment labor.
• Induction: The process of starting labor artificially, usually with medication or AROM.
• Augmentation: The process of speeding up labor that has already started, usually with medication or AROM.
• Pitocin (Oxytocin): A synthetic hormone used to induce or augment labor by stimulating uterine contractions.
• Epidural: A type of regional anesthesia that numbs the lower body, providing pain relief during labor.
• Spinal: A type of regional anesthesia similar to an epidural, but administered as a single injection into the spinal fluid. It provides faster pain relief but is usually used for Cesarean births.
• C-Section (Cesarean Section): A surgical procedure in which the baby is delivered through an incision in the mother's abdomen and uterus.
• VBAC (Vaginal Birth After Cesarean): A vaginal birth after a previous Cesarean birth.
• TOLAC (Trial of Labor After Cesarean): Attempting a vaginal birth after a previous Cesarean birth.
• Episiotomy: A surgical incision made in the perineum (the area between the vagina and anus) to enlarge the vaginal opening.
• Perineal Laceration: A tear in the perineum that occurs during childbirth. Lacerations are graded from first to fourth degree, depending on the severity.
• Forceps: A surgical instrument used to assist in the delivery of the baby's head.
• Vacuum Extraction: A device that uses suction to assist in the delivery of the baby's head.
• Meconium: The baby's first bowel movement, which can sometimes be passed in the amniotic fluid before or during labor.
• Fetal Distress: Signs that the baby is not tolerating labor well, such as an abnormal heart rate.
• Shoulder Dystocia: A complication of vaginal delivery in which the baby's shoulder gets stuck behind the mother's pubic bone.
• Breech: When the baby is positioned with the buttocks or feet presenting first.
• Transverse: When the baby is positioned sideways in the uterus.
• Occiput Anterior (OA): The most common and favorable fetal position for delivery, where the back of the baby's head (occiput) is facing the front of the mother's pelvis (anterior).
• Occiput Posterior (OP): A fetal position where the back of the baby's head is facing the back of the mother's pelvis (posterior). This position can sometimes lead to longer and more painful labor.

Postpartum Terms and Abbreviations

Understanding Fetal Heart Rate Monitoring

Fetal heart rate monitoring is a crucial part of labor management. It helps healthcare providers assess how the baby is coping with the stress of labor. Here's a breakdown of terms related to fetal heart rate patterns:

• Baseline FHR: The average fetal heart rate over a 10-minute period, excluding accelerations, decelerations, and marked variability.
• Variability: Fluctuations in the baseline FHR. It indicates a healthy nervous system. Variability can be minimal, moderate, marked, or absent. Moderate variability is generally considered reassuring.
• Accelerations: A temporary increase in the FHR of at least 15 bpm above the baseline, lasting at least 15 seconds. Accelerations are usually a sign of fetal well-being.
• Decelerations: A temporary decrease in the FHR below the baseline. Decelerations can be:
  • Early Decelerations: Gradual decrease in FHR that mirrors the contractions. They are usually caused by head compression and are generally benign.
  • Late Decelerations: Gradual decrease in FHR that starts after the peak of the contraction and recovers after the contraction ends. They are often associated with uteroplacental insufficiency (inadequate blood flow to the placenta).
  • Variable Decelerations: Abrupt decrease in FHR that varies in timing and shape. They are often caused by umbilical cord compression.
• Category I FHR Tracing: Considered normal. It includes a baseline FHR of 110-160 bpm, moderate variability, accelerations may be present or absent, and no late or variable decelerations.
• Category II FHR Tracing: Not predictive of abnormal fetal acid-base status, but requires continued evaluation and surveillance. It includes tracings with minimal or marked variability, absent accelerations after stimulation, recurrent variable decelerations, or prolonged decelerations.
• Category III FHR Tracing: Abnormal and predictive of abnormal fetal acid-base status. It requires prompt evaluation and intervention. It includes absent variability with recurrent late decelerations, recurrent variable decelerations, or bradycardia.
