Leopold maneuvers obstetric abdominal examination pregnancy

This clinical photograph captures an obstetric physical examination in a community or public health setting. A female patient is lying supine on an examination table with her abdomen exposed. The gravid abdomen is clearly visible, demonstrating significant distension consistent with pregnancy. The hands of a healthcare provider are positioned on the uterine fundus and lateral aspects of the abdomen, performing Leopold's maneuvers or a similar abdominal palpation to assess fetal position, presentation, or fundal height. The patient is wearing colorful traditional clothing, and the clinician is dressed in professional attire, including a white lab coat. The image illustrates a core procedural skill in maternal healthcare and prenatal screening, highlighting the clinical assessment of gestation within the obstetric and gynecological specialty. It serves as an educational resource for demonstrating patient positioning and manual examination techniques in low-resource or community health contexts.

The model is used for training in obstetrical maneuvers, specifically External Cephalic Version (ECV). The visual setup includes a lower body covered in light blue surgical scrubs and an upper torso draped in a patterned hospital gown. The central focus is a simulated gravid abdomen, constructed from skin-toned silicone layered over a pillowcase base. This abdominal component creates a smooth, rounded protuberance that replicates the anatomical appearance of a late-term pregnancy. The model is designed to house an internal 'uterus' mechanism—typically consisting of nested balloons and a fetal mannequin—to allow residents to practice palpation and the manual rotation of a fetus from a breech to a cephalic presentation. The image demonstrates the clinical application of simulation-based medical education (SBME) for improving procedural comfort and competency in obstetric care.

This clinical photograph illustrates a procedural setup for an obstetric ultrasound examination. The patient, a pregnant woman with a distended abdomen, is positioned supine on an examination table. A healthcare professional, positioned to the patient's right, is performing the scan using a curvilinear ultrasound transducer. A translucent coupling gel is visible on the lower abdominal region to facilitate acoustic transmission. The ultrasound machine's monitor is positioned at the patient's head level, displaying a real-time sonographic image of the fetus. The image demonstrates key aspects of maternal care and diagnostic imaging in obstetrics. Noteworthy anatomical features include the gravid uterus and striae gravidarum (stretch marks) on the abdominal skin. The clinical context relates to prenatal monitoring, fetal health assessment, and the study of maternal factors, such as obesity or insulin resistance, that may influence pregnancy and postpartum outcomes like lactation.

This diagnostic ultrasound image in the obstetric and gynecologic domain illustrates an abdominal pregnancy. The trans-abdominal scan reveals a fetus (marked with a white star) located outside the uterine cavity, positioned in close proximity to the maternal anterior abdominal wall. An empty, relatively amorphous uterus is identified separately (indicated by the white arrow). Key sonographic findings include the complete lack of myometrial tissue surrounding the fetus and the clear anatomical separation between the gestational sac and the uterine corpus. The fetus exhibits typical hyperechoic bony structures, while the adjacent uterine tissue presents a distinct, uniform echogenicity. This image serves as a clinical example of an extrauterine ectopic pregnancy, specifically an advanced abdominal pregnancy, emphasizing the diagnostic importance of identifying the relationship between the fetus and the empty uterus to prevent life-threatening maternal complications such as hemorrhage.

General and Obstetric Examination


PART 1: GENERAL EXAMINATION IN PREGNANCY

The general examination in a pregnant patient follows the same systematic approach as any medical patient, but specific signs related to pregnancy are sought at each step.

1. General Appearance

  • Build, nutritional status, pallor, jaundice, cyanosis, edema
  • Level of distress, anxiety, discomfort
  • Signs of systemic disease (thyroid enlargement, facial puffiness suggesting pre-eclampsia)

2. Vital Signs

ParameterClinical Relevance
Blood pressureHypertension (>140/90) - pre-eclampsia/gestational HTN; hypotension - aortocaval compression in supine position
Pulse rateTachycardia - anemia, infection, thyrotoxicosis, hemorrhage
TemperaturePyrexia - TORCH infections, chorioamnionitis, UTI
Respiratory rateTachypnea - pulmonary embolism, severe anemia, cardiac disease
WeightExcessive gain (>0.5 kg/week in 3rd trimester) - pre-eclampsia, polyhydramnios
HeightShort stature (<145 cm) - risk for cephalopelvic disproportion

3. Systematic General Survey

Eyes:
  • Pallor of conjunctivae - anemia
  • Scleral icterus - obstetric cholestasis, HELLP
  • Exophthalmos - Graves' disease
  • Papilledema - severe pre-eclampsia
Face:
  • Chloasma (melasma) - normal pregnancy pigmentation
  • Moon face - Cushing's syndrome
  • Facial edema - pre-eclampsia
Neck:
  • Thyroid enlargement - physiological or pathological goitre
  • Lymphadenopathy - infection, malignancy
Hands:
  • Koilonychia - iron deficiency anemia
  • Leukonychia - hypoalbuminemia
  • Peripheral edema, especially pitting pedal edema
  • Carpal tunnel signs - common in pregnancy
Skin:
  • Linea nigra, striae gravidarum - normal pregnancy changes
  • Spider naevi - hepatic disease or normal pregnancy (estrogen effect)
  • Jaundice
Breasts:
  • Enlargement, darkening of areola and nipple, Montgomery's tubercles - normal changes
  • Colostrum expression after 16 weeks
  • Lumps, mastitis signs

PART 2: OBSTETRIC (ABDOMINAL) EXAMINATION

This is the core of the obstetric assessment and is performed at every antenatal visit after 12-16 weeks. The patient should have an empty bladder and lie comfortably supine with head slightly elevated.

Sequence: Inspection → Palpation → Auscultation


A. INSPECTION

FindingSignificance
Size of abdomenConsistent with gestational age?
ShapeLongitudinal oval - normal; transverse - transverse lie
UmbilicusStretched/everted - common in pregnancy
SkinStriae gravidarum, linea nigra, scars (previous LSCS)
Fetal movementsVisible rippling movements in thin women
AsymmetryUterine fibroids, fetal position anomalies

B. PALPATION

1. Fundal Height Measurement

  • Measured from the upper edge of the pubic symphysis to the fundus using a tape measure
  • In centimeters, fundal height approximately equals gestational age in weeks (±2 cm) after 20 weeks
  • Fundal height > dates: multiple pregnancy, polyhydramnios, LGA fetus, uterine fibroids, wrong dates
  • Fundal height < dates: IUGR/SGA, oligohydramnios, transverse lie, wrong dates
Textbook of Family Medicine 9e, p. 3507 notes that larger-than-expected fundal height may indicate multiple gestation, fibroids, polyhydramnios, or an LGA fetus, and smaller-than-expected should prompt further workup.

2. Leopold's Maneuvers (Four Maneuvers)

These assess lie, presentation, position, and engagement of the fetus.
ManeuverActionDetermines
1st - Fundal GripPalpate the fundus with both handsWhat is in the fundus? (Head = hard, round, ballotable; Breech = soft, irregular, not ballotable)
2nd - Lateral/Umbilical GripBoth hands on lateral sides of abdomenFetal back (smooth, firm, resistant) vs. limbs (irregular, small parts felt); determines position (LOA, ROA, etc.)
3rd - Pawlik's GripRight hand grasps lower pole just above pubic symphysisPresentation (head or breech) and whether it is engaged or free
4th - Pelvic/Deep Pelvic GripFace patient's feet; both hands palpate lower uterine segmentDegree of engagement; descent of presenting part; direction of cephalic prominence
Tip: If not confident of fetal position after Leopold's maneuvers, intrapartum ultrasound should confirm lie - Pfenninger and Fowler's Procedures for Primary Care, p. 7126.

3. Assessment of Lie and Presentation

  • Lie: Relationship of fetal long axis to maternal long axis
    • Longitudinal (cephalic or breech) - normal
    • Transverse - always abnormal at term
    • Oblique - unstable, usually converts
  • Presentation: Part of fetus in lower uterine segment
    • Cephalic (most common, ~96%)
    • Breech (~4% at term): Frank breech, complete breech, footling/incomplete
    • Shoulder/Transverse
  • Position: Relationship of denominator (occiput for vertex, sacrum for breech) to maternal pelvis
    • LOA (Left Occiput Anterior) - most common
  • Engagement: Head engaged when biparietal diameter passes through pelvic inlet; in primigravida, occurs at ~36 weeks

C. AUSCULTATION

Fetal Heart Rate (FHR)

  • Normal FHR: 110-160 bpm
  • Heard best over the fetal back (for vertex: lower abdomen; for breech: above umbilicus)
  • Tools: Pinard's stethoscope (from 20 weeks), handheld Doppler (from 12 weeks)
  • Listen for 1 minute, count rate, note rhythm and character
  • Bradycardia (<110 bpm): fetal distress, cord compression
  • Tachycardia (>160 bpm): maternal fever, fetal infection, fetal anemia, prematurity

D. SPECIAL TESTS ON ABDOMINAL EXAMINATION

Ballottement:
  • Internal: finger in vagina - fetus floats away and returns (free head)
  • External: tapping one flank while opposite hand feels fluid thrill - checks for ascites/polyhydramnios
Fluid Thrill:
  • Positive in polyhydramnios; elicited by tapping one flank and feeling a transmitted impulse on the other, with the examiner's hand placed edge-on at the midline to block transmission through the abdominal wall

PART 3: VAGINAL (PELVIC) EXAMINATION IN OBSTETRICS

Indications:

  • First antenatal visit (Pap smear, pelvic assessment)
  • Assessment in labor (cervical dilatation, effacement, station, membranes)
  • Suspected preterm labor
  • Post-dates pregnancy

Findings to Assess (in labor - DECREM):

ParameterDescription
Dilatation0-10 cm (fully dilated)
EffacementCervical length shortening (0-100%)
ConsistencyFirm, medium, soft
RElation to pelvisPosition of cervix - posterior/mid/anterior
Engagement/station-3 to +3 (ischial spines = 0)
MembranesIntact or ruptured
Bishop Score combines these parameters to predict suitability for induction of labor.

PART 4: CLINICAL SIGNS SPECIFIC TO PREGNANCY

SignDescription
Chadwick's signBluish discoloration of vagina/cervix (6-8 weeks)
Hegar's signSoftening of the isthmus (6-8 weeks)
Goodell's signSoftening of the cervix
Osiander's signPulsation felt in lateral vaginal fornices
Braxton-HicksIrregular, painless uterine contractions
BallottementPassive movement of fetus through fluid

PART 5: SUMMARY - WHAT TO DOCUMENT AT EVERY ANTENATAL VISIT

  1. Gestational age (by LMP and/or ultrasound)
  2. Weight and BMI
  3. Blood pressure
  4. Urine dipstick (protein, glucose, nitrites)
  5. Symphysis-fundal height
  6. Fetal lie, presentation, position
  7. Engagement of presenting part
  8. Fetal heart rate
  9. Fetal movements (maternal perception and/or auscultation)
  10. Edema
