Q

Pathophys of Thromboembolic Disorders

A
  • physiologic changes of pregnancy contribute to Virchow’s triad
  • venous stasis in lower extremities from compression of IVC and pelvic veins by enlarging uterus
  • increased hormone-mediated deep vein capacitance secondary to increased circulating levels of estrogen & production locally of prostacyclin & nitric oxide
  • Progesterone: inc. decidual & hemostatic systems
  • doubling of fibrinogen levels
  • increases factors: 7,8,9,10,12 1000%
  • vWF inc 400%
  • 40% dec in free protein S conc. = resistance to activated protein C
  • returns to baseline 6 weeks postpartum

Hypermenorrhea
-synonymous with Menorrhagia
26
Polymenorrhea
-uterine bleeding occurring at regular intervals of less than 21 days
27
Intermenstrual Bleeding
-bleeding of variable amounts occurring between regular menstrual periods
28
Causes of Abnormal Uterine Bleeding: Pregnancy
- Implantation Bleeding - Abortion - Molar Trophoblastic - Ectopic
29
Causes of Abnormal Uterine Bleeding: Neoplasia/Anatomy
- vulva & vagina - cervix: squamous cell carcinoma - Uterine Corpus: uterine fibroids, endometrial cancer - ovary - endometriosis
30
Causes of Abnormal Uterine Bleeding?
- trauma - systemic disease: coagulopathies, blood dyscrasias, endocrinopathy - drug effects
31
Pregnancy on Asthma
- Dyspnea 60-70% all pregnant women | - pregnancy has unpredictable effect on underlying asthma
32
Asthma Effects on Infant
- increased risk IUGR - increased neonatal hypoxia - increased low birth rate - increased neonatal mortality
33
Best Measure of Pulmonary Function
-FEV1
34
Choice for Rescue inhaler in Pregnancy?
SABA- albuterol
35
Choice for Controller in Pregnancy?
ICS - Budesonide
36
Choice for ADD On in Pregnancy?
LABA - Salmeterol
37
What may cause bronchospasms and should be avoided in pregnancy?
Hemabate (PGF2)
38
Birth Control Pill Benefits
- dec. risk of ovarian & endometrial cancer - decreased dysfunctional uterine bleeding - menstrual regularity (inc. hemoglobin) - inc. SHBG so dec. androgens: less hirsuitism & acne - can be used "off label" for poly cystic ovary syndrome
39
Side effects of Oral Contraceptives
Estrogen: nausea, breast tenderness/enlargement - low does, increased breakthrough bleeding - unexpected bleeding common with low dose - older formulations with >50mcg of ethinyl estradiol caused more MI and stroke - venous thromboembolism: with combination pills especially in smokers
40
Progesterone-Only
"mini pill" - daily & continuously, no placebo - take at same time each day - best for women breast-feeding - women > 35 years old who smoke
41
Transdermal Patch
- mixe - new patch 3 weeks off for 1 week - less effective in women >90kg adipose tissue - breakthrough for 2 cycles - skin irritation
42
Prevalence of Urinary Incontinent
10-35% of adults - women>men - patients under-reporting
43
Classifying Urinary Incontinence
- stress - urge - mixed - overflow - functional - unconscious or reflex - fistula
44
Management Urinary Incontinence
- assess - understand risk factors & reversible causes - treat reversible conditions - educate - treat to improve quality of life - agree on management plan
45
Risk Factors of Urinary Incontinence
F>M | menopause, childbirth, immobility, environmental barriers, altered cognition, meds, smoking, collagen disorders,
46
Increased risk of Urinary Incontinence with past medical history?
- parity | - any repairs or other birth trauma (forceps/vacuum)
47
Drugs to prevent voiding?
- anti-cholinergic | - alpha-adrenergic
48
Drugs to promote voiding?
- cholinergic-bladder irritability | - alpha-blocking-decrease sphincter tone
49
Diet and Urinary Incontinence?
caffeine spicy foods alcohol citrus food & drinks
50
Q-Tip Test
-assesses bladder neck mobility -sterile technique -anesthetic gel +30> hypermobility -stress urinary incontinence (SUI) often has hypermobility, but if have it not necessarily SUI
51
Laboratory Testing Urinary Incontinence
Urinalysis & Culture - bacterial mucosal irritation - endotoxin inhibition of alpha-adrenergic receptors in urethra
52
To hold the urine??
-urethral pressure must be greater than bladder, abdominal, volume pressure
53
Treatment of Urinary Incontinence
- treat reversible conditions first - behavioral therapy - medications - devices - surgery
54
Reversible Causes of Urinary Incontinence
- UTI - atrophic urethritis/vaginitis - dietary - meds - excess fluid intake/caffeine - delirium - phychological - restricted mobility
55
Nonsurgical Treatment of Stress incontinence
- Kegel exercises (stop peeing mid stream, then start again) - Pessaries: requires regular care, managed by patient - Fem-Soft (helps prevent leaking)
56
Surgical Treatment of Stress Incontinence
- Burch Retropubic Urethropexy - Sling (mesh: have erosion/problems) - Urethral Bulking: inject substance to close urethra up some (if to much can't pee)
57
Symptoms of Prolapse
- pressure - bulge "down there" - vaginal irritation/Ulvers ***pain is not presenting symptom***
58
Symptoms of Anterior Prolapse
- stress urinary incontinence - incomplete bladder emptying - possible increased frequency of UTIs
59
Symptoms of Posterior Prolapse
- incomplete stool evacuation | - splinting to assist defecation
60
Risk Factors of Prolapse
- childbirth - increased intra-abdominal pressure (chronic cough/lifting/obesity/constipation/straining) - Neurologic Injury - Genetic Predisposition (connective tissue abnormalities) - Estrogen Deficiency
