Clinical OB/GYN Flashcards
Sympathetic Innervations
Ovaries: T9-10
Uterus: T10-L1
Cervix: T10-L2
Increased sympathetic tone
Ovaries: increased vasoconstriction > decreased blood flow
Uterus: increased uterine contraction, increased vasoconstriction
Cervix: relaxes cervix
Parasympathetic innervations
Ovaries: Vagus/S2-4
Uterus: S2-4
Cervix: S2-4
Increased parasympathetic tone
Ovaries: increased vasodilation > increased blood flow
Uterus: increased relaxation of uterus, increased vasodilation
Cervix: constricts cervix
Ovaries Chapman’s
Anterior: pubic tubercles
Posterior: T10 transverse processes
Uterus Chapman’s
Anterior: inferior pubic rami
Posterior: L5 transverse processes
Broad ligament Chapman’s
Anterior: lateral ITB
Posterior: PSIS
Junction levels
Pelvic - L5-S1 (LS)
Thoracic - T12-L1 (TL)
Thoracic inlet (C7, T1, 1st rib) - CT
Suboccipital (OA, AA)
1st trimester postural changes
- More weight bearing on LS junction > sacral extension
- Pubic shear tenderness at pubic symphysis
- Posterior rotation of pelvis
- Decrease of lumbar lordosis
- Hyperemesis gravidarum > tx w/ parasympathetics, occipitomastoid suture decompression (vagus), sacral rocking/inhibition
Common SD in 1st trimester
- C2 with recurrent SD and T2 locking
- T4-T8 SD d/t breast tenderness/enlargement
- Pelvis and sacral; pain at pubic symphysis
2nd trimester postural changes
- Increased lumbar lordosis
- Anterior rotation of pelvis
- shortening of paraspinal mm.
- increase in thoracic kyphosis
- diaphragm restrictions
- anterior rotation of shoulder girdle
- cervical lordosis
- thoracic and rib pain
Symptoms and SD in 2nd trimester
- Uterus into abdomen > pain over pubic symphysis
- MFR and CS safest
- hand and wrist pain from carpal tunnel common (edema causes compression of median n.)
- De Quervains’ Tenosynovitis common too
- Tx of pectoral girdle and upper thoracics (sympathetics to UE @ T2-7), stretch of transverse carpal lig., or active articulation of carpal bones
3rd trimester postural changes
- Breast enlargement with increased stress @ T5-8
- Lumbar lordosis
- anterior pelvic rotation with exaggerated sacral flexion
- Compression @ L5-S1
- Stress on lumbar facets
- SI and pubic pain
Symptoms and SD in 3rd trimester
- GERD (restrictions in excursion of diaphragm affect GE junction and as fundus enlarges, abdominal contents compressed)
- pubic symphysis widens (hormonal influence of estrogen and relaxin) > predisposes to pubic shear, LS pain may increase (less able to lie prone), LE edema, constipation, hemorrhoids d/t compression on pelvic organs and vasculature
- Upper rib SD (exhalation)
- iliopsoas strain (usually bilateral, pelvic side shift away from tight psoas, increased LS pain), LE edema, constipation, hemorrhoids
- piriformis syndrome (pain in butt w/ radiation into calf or foot, assoc with piriformis, mid-pole SI, and greater trochanter TPs)
Organic causes of low back pain in pregnancy
- Pyelonephritis (fever/chills), nephrolithiasis
- preterm labor (<37 weeks)
- PID/UTI
