OB Patients Flashcards
Why do more than 60% of pregnant patients report LBP?
- Changes in maternal structure and biomechanics
- Changes in hormones
- Fluid circulation
Research in pregnant women who underwent OMT
Previous research indicates that all women in that study had back pain, but those that are treated with OMM have better functional scoring.
Pregnant woman with scoliosis: how does it change during pregnancy?
- Curvature does NOT increase,
- Pain may increase.
- Possible increased risk of premature bb.
Pregnant woman with Rheumatoid arthritis: how does it change during pregnancy?
- Symptoms improve from [conception => post-partum]
Pregnant woman with Ankylosing Spondylitis: how does it change during pregnancy?
- Worsened with pregnancy due to increase stress on SI joint
What MSK Changes occur during pregnancy?
- LB
- Neck
- Shoulder
- Abdominal muscles
- Anterior and posterior longitudinal L
- Pelvis
- SI joint/ pubic symphysis
- Structures
- Ligaments
- ↑ lordosis in LB
- Neck flexes forward
- Shoulders move downward
- Abdominal muscles weaken/ seperate
- Anterior and posterior longitudinal L => joint laxity
- Pelvis tilts ANTERIORLY
- SI joints/Pubic symphysis widen and increase mobility
- Fluid retention => compression of structures
- Ligamentous laxity
What affect does forward/anterior tilting of the pelvis cause?
↑ lordosis in lower back to counterbalance => ↑ stress on vertebra and ↑ shear across IV discs
As pregnancy progesses, distension of the abdomen =>
weakens muscls ability to counterbalance
A 29 yo primigravid (pregnant for the first time) female presents to her OB for her 37 week appointment. The patient complains of back pain that has been present for several months but is “becoming unbearable.” The pain worsens with activity and is alleviated by rest. The pain is generally localized to her low back, but at times radiates down the back of her thighs. Her sleep has progressively deteriorated during the pregnancy, but the patient reports worse back pain at night, especially with turning. Which of the following will most likely be found on physical exam?
A.+1/4 Achilles reflex bilaterally
B.Decreased ROM of lumbar spine
C.3/5 Muscle strength of hip flexor bilaterally
D.Increased pain on pelvic compression
E.Leg length discrepancy
B. decreased ROM of lumbar spine
What is the etiology of LBP in the past patient?
- Posterior pelvic pain => LBP (distal and lateral lumbosacral junction) due to relaxation of ligaments => down posterior thigh & knee.
- No muscle weakness
- No sensory impairment
- NL reflexes (2/4)
Alarm findings: What s/sxwould grant referral for further evaluation in a patient with posterior pelvic pain (located distal and lateral to lumbosacral junction)?
- Severe pain that interferes with fx, esp if laying asleep at night
- Pain increases w cough, sneezing or valsalva
- Neuro problems (bowel/bladder dyx, weakness, sensory deficits, ABNL reflezes)
Pregnant women who has radicular pain
- Etiology:
- Due to:
- Presenatation:
- Etiology: Bulging disc (40%); herniated disk (10)
- Due to: Ligmentous structures apply pressure on nerve root of (geniitofemoral or ilioinguinal nerve)
- -Presentation: paresthesias and “ lightening pain” in ilioinginal/genitofemoral nerve root distribution (anterior thight)
RF for LBP in pregnancy (7)
- ◦Previous history of LBP
- ◦Pain during menstruation
- ◦Multiparity
- ◦Higher BMI
- ◦Smoking
- ◦Age
- ◦Strenuous work
Outcome of LBP in pregnancy
80-95% resolve
During pregnancy, changes do we see in lymphatics, venous and hormoneal
- Increase intersitial fluids by 6.5 L due to increased demand of pelvic organs
- Tissue edema due to Increase [estrogen, progesterone and adrenal hormones]
What are the non-painful palpable bumps patients can get during pregnancy?
Vulvular variscosities
How to treat vulvular variscotisies that occur in pregnancy?
Tell pt to sleep left LR.
How is Left LR a treatment for vulvular varisocities in pregnancy?
Increases CO
- When supine: ↓ CO => ↓ preload => ↓ SVR => ↑ HR, seen mostly at > 20 weeks
Cardiac output is higher when the pregnant woman lays _____
on her left side
What changes in pregnancy are MOST common in 3rd Trimester?
↑ venous stasis => decrease lymphatic flow => Hemorrhoids, vulvar, and LE varicosities
What are the causes of decreased lymphatic flow (pressure gradient) in pregnancy?
1. Fascial torsions
2. Organ hypertrophy
3. Diaphragm restriction
Pregnant patient has LBP that hurts MORE THAT NIGHT, even though she is very active during the day. What is her problem?
Venous stresses: more blood (fluid) gets to the tissues than can be returned/removed by the venous and lymphatic systems => stagnant hypoxia of the neural and vertebral tissues => delayed LBP
