Braxton Hicks Contractions
- John Braxton Hicks, an English physician, first described it in 1871.
- Physiological myometrial contraction.
- Sporadic & usually starts at around 6 weeks.
- Visualized on ultrasound in 2nd & 3rd trimesters.
- In late pregnancy, these contractions cause false labor.
Ultrasound Findings:
- Appears as focal 'transient' myometrial thickening making confusion with fibroid or retroplacental abnormality. These abnormalities are not transient & fibroid will have a thin echogenic pseudocapsule.
- Give bed rest and recheck after an hour. Fibroid won't change its shape.
