Leopold’s Maneuvers

Leopold’s Maneuvers are methods to determine position, presentation and engagement of fetus.

They will include:

1. Determination of what is in the fundus
2. Evaluation of the fetal back and extremities
3. Palpation of the presenting part above the symphysis, and
4. Determination of the direction and degree of flexion of the head.

How to Perform Leopold’s Maneuver

Before performing Leopold’s Maneuver, ask the mother to empty the bladder, warm hands, and apply them to the mother’s abdomen with firm and gently pressure.

First Leopold’s Maneuver:

1. It will determine which part of the fetus is in the fundus.
2. Place pals on each side of the upper abdomen and palpate around the fundus
3. You would feel a hard, round, movable object if the head is in the fundus
4. You would feel soft and have an irregular shape and are more difficult to move if the buttock is in the fundus

Second Leopold’s Maneuver:

1. Move hand downward over each side of the abdomen, applying firm, even pressure.
2. The fetus’s back which is a smooth, hard surface should be felt on one side of the abdomen.
3. The hands, feet, elbows, and knees which are as irregular knobs and lumps will be felt on the opposite side of the abdomen.

Third Leopold’s Maneuver:

1. It will determine fetal position
2. Place hand above the symphysis pubis
3. Bring thumb and fingers together and grasp the part of fetus between them that may be the head or the buttocks

Fourth Leopold’s Maneuver:

1. It is used in the late stage of pregnancy to determine how far the fetus has descended into the pelvic inlet.
2. Place hand on the sides of the lower abdomen close to the midline
3. Slide hands downward and press inward
4. If you have determined that the buttocks are in the fundus, then feel for the head
5. If you cannot feel the head, it probably has descended

Mechanism of Labor

There are eight classical steps in the normal mechanism of labor as following here:

Engagement

• This is also called lightening or dropping
• The fetus nestles into the pelvis

Descent

• This process starts from the time of engagement until birth and is assessed by the station.
• The fetal head undergoes as it begins its journey through the pelvis.

Flexion

• The fetal head’s nodding forward toward the fetal chest
• While descending through the pelvis, the fetal head flexes so that the fetal chin is touching the fetal chest. This functionally creates a smaller structure to pass through the maternal pelvis

Internal Rotation

• With further descent, the occiput rotates anteriorly and the fetal head assumes an oblique orientation. In some cases, the head may rotate completely to the occiput anterior position.

Extension

• It begins after the head crowns
• This means that the fetal chin is no longer touching the fetal chest.
• It enables the head to emerge when the fetus is in a cephalic position
• The extension of labor is completed when the head passes under the symphysis pubis and occiput and the anterior fontanel, brow, face and chin pass over the sacrum and coccyx and are over the perineum

Restitution

• After the head emerges, the fetal head becomes in a realignment

External Rotation

• The shoulder of fetus externally rotates after head emerging and restitution
  
• The shoulder is in the anteroposterior diameter of the pelvis.

Expulsion

• This is the birth of entire body.
