Kisner ch 24 womens health Flashcards
The ligaments connected to the pelvic organs are more __________ than the ligaments supporting joint structures
fibroelastic
Why do women have an increased chance of contracting an UTI during pregnancy?
the perpendicular angle of the ureters may cause a reflux of urine out of the bladder and back into the ureter which can cause urinary stasis
How does pregnancy effect the orientation of the ribs?
hormones stimulate change in rib position, subcostal angle progressively increases and ribs flare up & out
Why does the diaphragm elevate by 4cm?
due to rib change in position (flaring up & out)
What occurs to the respiration rate with pregnancy?
RR unchanged but depth of respiration increases, TV & min ventilation increase but total lung capacity stays the same or slightly decreases
There is a natural state of ___________ to meet the oxygen demands of pregnancy
hyperventilation (15-20% o2 increase)
What is present during mild exercise as early as 20 weeks into pregnancy because of hyperventilation ?
dyspnea
Describe the “physiologic anemia” of pregnancy
plasma increase is greater than red blood cell increase; occurs to meet the O2 demands of pregnancy
What occurs to venous pressure in the LEs during standing?
increases as a result of increased uterine size & increased venous distensibility
What occurs to cardiac output and blood pressure w/ pregnancy?
CO increases, BP decreases
What occurs late in pregnancy especially in the supine position?
pressure in the inferior vena cava rises, caused by compression by the uterus just below the diaphragm, some women may experience hypotensive syndrome due to the decrease in CO
What occurs to the heart during pregnancy?
The heart size increases and it is more elevated b/c of the movement of the diaphragm
In what position is CO significantly increased during pregnancy?
woman is sidelying in which the uterus places the least pressure on the aorta
How many bpm does the HR increase? What % does CO increase during pregnancy?
10-20bpm, 30-60%
what occurs to the abdominal muscles (linea alba, retus) during pregnancy and how does that affect their strength?
the muscles become stretched, decreasing the ability to generate a strong contraction which decreases their efficiency of contraction
How does the shift in COG affect the abdominal muscles during pregnancy?
decreases the mechanical advantage of the muscles
What occurs to the pelvic floor muscles in terms of location during pregnancy?
must be able to hold changes in weight (antigravity position), pelvic floor drops 2.5cm
Generally what occurs to the connective tissues and joints during pregnancy?
hormones cause a systematic decrease in ligamentous tensile strength, joint laxity increases, ligamentous laxity increases, joint hypermobility
Why does the thoracolumbar fascia lengthen during pregnancy and how does that affect its ability to stabilize and support the trunk?
b/c of its attachment to the abdominal wall the fascia is lengthened and this diminishes its ability to support/stabilize the trunk effectively
What occurs to the metabolic rate and head production during pregnancy?
both increase
How many calories must be consumed to keep up w/ the increased BMR?
300 calories per day
What occurs to the COG during pregnancy?
shifts upward & forward b/c of the enlargement of the uterus & breasts
What occurs in the lumbar & cervical spine due to the shift in COG?
lordoses increase to compenstae for shift in COG
What occurs in the shoulder girdle and upper back due to the change in COG?
become rounded w/ scapular protraction & UE IR b/c breast enlargement
Tightness in the pec muscles and weakness of the scapular stabilizers are due to pregnancy? True or False
BOth! it can be due to preexisting conditions or induced by the pregnancy
What may occur in the knees due to the change in COG?
genu recurvatum will shift the weigh toward the heels in an attempt to counteract the anterior pull of the fetus
What occurs to the suboccipital muscles w/ the change of COG ?
maintain appropriate eye level (optical righting reflex), moderate forward head posture to go w/ the protracted scapula
Post pregnancy why might a women still have some of the postural changes that occur during pregnancy?
Some postures become habits, many child care activities contribute to persistence postural faults & asymmetry
What are some compensatory strategies the body will use to help redistribute weight and help w/ balance during pregnancy?
walks w/ wider BOS, increased ER of hips
describe shapes/layers of the pelvic floor musculature
sling/hammock orientation, figure eight orientation of the muscles around the orifice of the urethra/vagina & anal spinchter, funnel shape of the pelvic muscles
The pelvic floor musculature is composed of 3 layers in a _________ orientation w/ boney attachments to _______ &______.
The pelvic floor musculature is composed of 3 layers in a funnel shaped orientation w/ boney attachments to the pubic bone & coccyx
What is the prime mover of the pelvic floor
levator ani
What type tissues form the pelvic diaphram?
levator ani & coccygeus
What are the superficial muscles of the pelvic floor?
superficial transverse perineal muscles , ischiocavernosus, bulbocavernouss , external anal sphincter
The combined action of the pelvic floor muscles create what type of motion and in what direction?
superior force toward the heart and a puckering or drawstring motion around the spincters
What are the essential roles of the pelvic floor?
provide support to pelvic organs, able to withstand increased intra abdominal pressure, help stabilize the spine/pelvis, maintain continence at the urethral/anal sphincters, sexual resonse & reproductive function
What nerve supply the perineal tissues including their terminal branches?
pudendal nerve (3 terminal branches: dorsal, perineal, rectal), levator ani nerve, direct branches from the sacral nerve roots
how does muscle injury during vaginal birth affect vaginal closure pressure and the pelvic floor complex?
it diminished the maximal closure pressure of the pelvic floor complex, makes the pfc more vulnerable to increased abdominal pressure & may lead to prolapse
What is an episiotomy?
an incision made in the perineal body & is considered a 2nd degree laceration (forceps assisted delivery)
What is a prolapse?
Supportive impairment, descent of any of the pelvic viscera out of their normal alignment b/c of muscular, fascial, and/or ligamentous deficits & b/c of increased abdominal pressure
As the prolapse progresses what symptoms may the pt experience?
perineal pressure & heavyness, low back pain, abdominal pressure or pain, difficulties w/ defecation
What are the statistics for urinary incontinence and is is mostly affected?
15million ppl, women are twice as likely than men to have symptoms : suffer from social discomfort, anxiety regarding leakage & hygiene concerns
describe how strengthening of the pelvic floor can aide in preventing urinary incontinence and other pelvic floor dysfunctions
it improves structural support of the organs & connective tissue in addition to facilitating more effective recruitment of motor units & more consistent, proficient contractions
What are other factors that contribute to pelvic floor dysfunction for women who have never been pregnant
excessive straining b/c of chronic constipation, smoking, chronic cough, obesity, hysterectomy, (possibly the depletion of estrogen)
Why is patient education so important for pelvic floor impairments?
pt should understand all 3 dimensions of the complex, teach the patient the muscular orientation, provide verbal/detailed instructions
Describe the 3 dimensions of the pelvic floor muscle complex
sling/hammock fibers, the figure 8 orientation of the musculature, “funnel” configuration extending inferiorly to the outlet
What motion does the circumferential fibers produce in the pelvic floor?
drawstring or “pucker” effect
