OB-GYN Flashcards
Existing stresses (gravity) aggravated by pregnancy
Aggravates AP postural curves
Fascial torsions
Why do pregnant patients get congested?
More blood gets to the tissues than can be removed by venous system
Abdominal diaphragm is an extrinsic pump –it has a decreased efficiency due to the changes induced by the spinal curve change
Somatic dysfunction in pregnancy can increase energy requirements up to
300%
HorMechanical effects of pregnancy hormones
Weakening of muscle and supporting ligaments
Increased fluid retention
2 mechanical effects of pregnancy
Changed center of gravity
Organ hypertrophy
Physiological stresses of pregnancy
Increased ISF
Increased circulating volume to support the hypertrophy of the organs
Increased fluid retention mediated by estrogen and adrenal hormones
Venous stresses of pregnancy
Congestion of CNS
Changes in volume of organs (increase)
Increase cavity pressures
Relative reversal of venous blood flow (valveless system in CNS)
Relative CI for OMT during pregnancy (5)
Toxemia of pregnancy (decreased seizure threshold) PROM Premature labor Abruptio placenta Ectopic pregnancies
2 osteopathic principles addressed in OMT of pregnancy
The body has self-regulatory mechanisms which will provide optimal compensation for the stresses of pregnancy if they are free to work efficiently.
Distinctive osteopathic care is based upon the belief and the clinical observations that within the body unit, structure and function are reciprocally interrelated and interwoven with optimum homeostasis.
Structural Stage (0-28 weeks) results in
increased fat storage
growth of the uterus
hypertrophy of the breast and other tissues
blood volume expansion
shift on center of gravity
pelvis rocks forward
increased lumbar lordosis
compensatory thoracic kyphosis will develop in cervical/suboccipital area
muscles and ligaments more vulnerable to mechanical stresses
Tx of structural stage
Evaluate initial status
past trauma, current problems
manipulation based on exam
addresses pre-existing conditions and body changes related to pregnancy
Congestive stage (28-36 weeks)
more fluid accumulates in the tissues than can be effectively removed by the venous and lymphatic systems
congestion is mechanical/hormonal/biological
associated with decreased oxygenation and cellular nutrition
expanding uterus
-“ball valve” between veins of legs and vena cava
-hypotensive when supine
-limits chest volume
-diaphragm must work harder
Tx o congestive stage
treat common compensatory pattern to maintain freedom of the fascial pathways and thus improve lymphatic drainage
maintain symmetry of thoracic inlet
relax thoracolumbar junction (diaphragm attachment)
diaphragm doming
Preparatory stage (36 weeks-delivery)
maintain good structural balance and support lymphatic flow
build psychological support for delivery
carefully check the craniosacral mechanism
What can help with pain control during labor?
Sacral pressure
