From the Guidelines
The primary goal of the third Leopold maneuver is to identify the presenting fetal part in the lower uterine segment, which is crucial for determining fetal presentation and planning delivery. This is achieved by palpating the abdomen to determine the position of the fetus, as outlined in the American Family Physician guidelines for intrapartum fetal monitoring 1. The third Leopold maneuver involves placing one hand just above the pubic symphysis and grasping the lower portion of the uterus between the thumb and fingers to identify whether the presenting part is hard and round (indicating the head) or softer and irregular (suggesting the breech).
Key aspects of the third Leopold maneuver include:
- Determining fetal presentation, which directly impacts delivery planning and management
- Identifying whether the presenting part is engaged in the pelvis, which can affect delivery outcomes
- Assessing fetal position, presentation, and engagement in preparation for delivery, as recommended in the guidelines for intrapartum fetal monitoring 1
The importance of accurately determining fetal presentation and position is highlighted in the guidelines, which emphasize the need for regular assessments during labor, including palpation of the abdomen to determine fetal position 1. By performing the third Leopold maneuver, healthcare providers can gather critical information to inform delivery planning and ensure the best possible outcomes for both mother and baby.
From the Research
Leopold Maneuvers
The Leopold maneuvers are a series of four abdominal palpations used to determine the position, presentation, and engagement of the fetus in the womb.
Third Leopold Maneuver
- The goal of the third Leopold maneuver is to identify the small parts of the fetus, such as the feet, knees, or elbows, and to determine the presentation of the fetus, whether it is cephalic (head-first), breech (feet-first), or transverse (lying across the womb) 2.
- This maneuver involves palpating the abdomen to feel for the fetal small parts and to determine the presentation of the fetus.
- The accuracy of the third Leopold maneuver in determining fetal presentation can be influenced by various factors, including the experience of the operator, the size and position of the fetus, and the presence of any uterine or fetal anomalies 3, 4.
- Studies have shown that the Leopold maneuvers, including the third maneuver, can be an effective method for determining fetal presentation, but may not always be accurate, especially in cases where the fetus is in a non-vertex presentation 5, 6.
