A 28-year-old woman, gravida 1, para 0, at 36 weeks gestation presents for a routine prenatal visit. The pregnancy has been uncomplicated. To systematically determine the fetal lie, presentation, position, and engagement, the physician performs Leopold maneuvers. Arrange the distinct steps of the Leopold maneuvers in their standard sequential order, from the first maneuver to the fourth maneuver, as performed during an obstetric examination.
- 1Palpation of the uterine fundus to determine whether the fetal head or breech occupies the superior aspect of the uterus
- 2Bilateral palpation of the lateral maternal abdomen to identify the orientation of the continuous fetal back versus the small extremities
- 3Single-handed grasp of the lower maternal abdomen just above the pubic symphysis to assess the mobility and identity of the presenting part
- 4Bilateral deep palpation of the lower uterine segment while facing the patient's feet to assess the attitude and cephalic prominence of the fetal head
Answer
The standard sequence of Leopold maneuvers is: 1) Palpating the fundus, 2) Palpating the lateral abdomen to find the fetal back, 3) Grasping the lower abdomen above the pubic symphysis, and 4) Palpating the lower uterine segment while facing the patient's feet.
Leopold maneuvers follow a standard protocol to systematically map the fetus within the uterus. The examiner begins at the top of the uterus (fundal grip) to identify the fetal pole. Next, the examiner moves laterally (umbilical grip) to locate the continuous, firm fetal back. Then, the examiner uses one hand at the lower abdomen (Pawlik's grip) to determine what fetal part is presenting at the pelvic inlet. Finally, the examiner changes position to face the patient's feet and uses both hands (pelvic grip) to assess the fetal head's attitude (flexion or extension) and depth of engagement in the maternal pelvis.
Step-by-Step Solution
Key Concept
Leopold maneuvers are a systematic, four-step tactile examination of the maternal abdomen used to accurately determine fetal lie, presentation, position, and engagement.
