Introduction:
Each menstrual cycle, the endometrium (uterine lining)
prepares with
itself to nourish a fetus. If fertilization
doesn’t occur, the body sheds the endometrium during the monthly (on average)
cycle. In some cases, irregularity can occur in this cycle, indicating any of
the following menstrual disorders:
- Disorders of cycle
length:
Normal menstrual cycle length is
21- 35 days average 28 days
1)
Oligomenorrhea: is a
condition in which you have infrequent menstrual periods more than 35
days.
2)
Polymenorrhea: is a term
used to describe a menstrual cycle that is shorter than 21 days.
- Disorders of cycle
flow:
Normal menstrual cycle flow length
is 3-7 days
1)
Hypomenorrhea: is a
menstrual bleeding lasting less than 2 days or the loss of less than 30 mL of
blood heavy flow.
2)
Menorrhagia: is a menstrual
bleeding lasting more than 7 days or the loss of more than 80 mL of blood heavy
flow.
3)
Metrorrhagia: irregular
frequent bleeding of varying amounts but not excessive.
- Disorders of
ovulation:
Disorders of ovulation include
anovulation and oligoovulation.
1) Anovulation: is the absence of ovulation
when it would be normally expected, anovulation usually manifests itself as
irregularity of menstrual periods, that is, unpredictable variability of
intervals, duration or bleeding
. Anovulation can also cause cessation of periods or
excessive bleeding
"Dysfunctional uterine
bleeding"
-
Non-menstrual bleeding:
Post coital bleeding: is bleeding from the
vagina in women after sexual intercourse and may or may not be associated with
pain.
-
AUB classification according to
age:
❖ Childhood and adolescence bleeding:
1) Foreign body. 2)
Hormonal changes.
❖ Childbearing period bleeding.
❖ Perimenopausal bleeding:
1) Atrophy “most common”
2) Malignancy “most serious”: - Cervical tumor.
-
Endometruim tumor.
-
Ovarian tumor.
❖ Postmenopausal bleeding.
Childbearing
period
1) Exclusion of contraceptive method.
2) Exclusion of pregnancy:
N.B in case of positive
pregnancy test may be:
➢ Abortion.
➢ Vesicular mole.
➢ Ectopic pregnancy.
N.B in case of negative pregnancy test:
1) Organic lesion: referred to as PALM
➢ Uterine polyp.
➢ Malignancy.
➢ Leiomayoma.
➢ Adenomyosis.
2)
Inorganic lesion:
➢ Systemic.
➢ Chronic disease.
➢ Anovulation. “DUB”.
-
Definition of DUB:
Is defined as AUB that occurs in absence of
recognizable pelvic pathology, medications, systemic disease, trauma, or
pregnancy.
➢ Age incidence: 20% at
adolescence, 40% in patients >40 years, 60% in child bearing period
➢ Causes of DUB:
Most of the time, DUB happens because of
changes in the body’s hormone levels.
For teen girls, one of the most common
causes of hormone changes is when the body doesn’t release an egg from one of
the ovaries. This is called anovulation.
The release of an egg is part of the hormone
process that makes up the menstrual cycle. If a girl’s body doesn’t release an
egg, too much extra blood and tissue can build up in the lining of her uterus.
When that lining eventually leaves the body, a girl can have more than normal
amounts of bleeding. This bleeding might happen as part of a period or in
between periods.
Anovulation is most likely to happen after
a girl first starts getting her period. That’s because the ovaries aren’t fully
developed yet. It can last for several years until a girl’s periods become
regular.
Other things can lead a girl to
develop DUB:
- Some illnesses (like thyroid disease or polycystic ovary
syndrome) can mess with the body’s hormones.
- Problems like compulsive exercise, not eating healthy foods, or
too much stress can cause hormone changes.
➢ Signs and symptoms of DUB:
Symptoms that can
occur with DUB are:
- Breast tenderness.
- Bloating.
- Pelvic pain or
pressure.
- Dizziness.
- Fainting.
- Weakness.
- Low blood pressure.
- Increased heart
rate.
- Pale skin.
- Pain.
- Passing large clots.
- Soaking a pad every hour.
➢ Diagnosis of DUB:
(1) Physical diagnosis:
The physical exam should include:
1)
Vital signs, including
blood pressure and body mass index (BMI).
2)
Signs of pallor, such as
skin or mucosal pallor.
3)
Signs of endocrine
disorders.
4)
Examination of the thyroid
for enlargement or tenderness.
5) Excessive or abnormal hair growth patterns, clitoromegaly, acne
that could indicate hyperandrogenism.
7) Moon faces, abnormal fat distribution,
striae that could indicate Cushing's.
6)
Signs of coagulopathies,
such as bruising or petechiae.
7)
Abdominal exam to palpate
for any pelvic or abdominal masses.
8)
Pelvic exam: Speculum and
bimanual. - PAP smear if indicated.
- STI screening
(such as for gonorrhea and chlamydia) and wet prep if indicated.
)2( Local examination:
➢ Bimanual pelvic examination: To
exclude uterine leiomyomas, adenomyomas, and adnexal masses.
➢ Speculum examination: To exclude cervical polyp, erosion, ulcer,
mass, or associated vaginal pathology.
(3) Laboratory tests:
➢ Ultrasound:
To
view your reproductive organs. This examination will reveal whether you have
any abnormal growths, such as polyps or fibroids. It can also help to rule out
internal bleeding.
➢ Blood tests:
Blood tests are used to measure hormone
levels and complete blood count. Hormone levels can often give quick insight
into the cause of bleeding.
In case of heavy or prolonged bleeding, a
complete blood count reveals whether red blood cell count is too low. A low red
blood cell count can indicate anemia.
➢ Human chorionic gonadotropin (HCG):
For acute bleeding, a type and cross should be obtained.
➢ Thyroid-stimulating hormone (TSH) level
and prolactin level:
If anovulation is suspected.
➢ Endometrial biopsy:
If an abnormal growth is causing the
bleeding, or uterine lining is unusually thick, doctor will take a sample of
the uterine tissue for testing. If there are any abnormal cell changes in the
lining, a biopsy will reveal it. Abnormal cells can indicate hormone imbalances
or cancer, among other things.
➢ Diagnostic Procedures:
- Pap smear:
❖ To screen for cervical cancer if age >21 years.
- EMB should be performed
in:
❖ Women age >35 years with AUB to rule out cancer or
premalignancy.
❖ Postmenopausal women with ET ≥4 mm.
❖ Women aged 18 to 35 years with AUB and risk factors for
endometrial cancer.
❖ Perform on or after day 18 of cycle, if known; secretory
endometruim confirms ovulation occurred.
- Dilation and curettage
(D&C):
❖ Perform if bleeding is heavy, uncontrolled, or if emergent
medical management has failed.
❖ Perform if unable to perform EMB in office.
- Hysteroscopy:
❖ If another intrauterine lesion is suspected.
➢ Medical management:
(1)
Non-hormonal
therapy:
❖ Non-steroidal anti-inflammatory drugs "NSAIDs".
❖ Antifibrinolytic
drugs: Tranexamic acid (to inhibit the increased plasminogen activators and
plasmin).
(2)
Combined
oral contraceptive pills:
❖ Low-dose oestrogen-progestogen is used (regulate the cycle and
reduce amount of blood loss)
❖ Progestogen dominant pills is used in progesterone deficiency
and oestrogen dominant pills are used in oestrogen deficiency.
(3)
Oestrogens:
❖ Used
in anovulatory cycles to reduce the blood loss.
(4)
Levonogestrel
- releasing IUCD:
❖ Induces
endometrial atrophy with reduction of blood loss
(5)
Androgens
and Gonadotropin releasing hormone:
❖ Used when the above medical therapy has failed or surgery is
contraindicated.
➢ Nursing management of DUB:
✓ Assess maternal physiological circulatory status and blood
volume.
✓ Monitor vital signs including systolic and diastolic blood
pressure, pulse and heart rate.
✓ Measuring the level of hemoglobin in the blood to prevent
anemia.
✓ Educate the client about normal menstrual cycle and the possible
causes for her abnormal pattern.
✓ Inform the woman about treatment option.
✓ Inform her about any prescribed medication.
✓ Encourage patient to comply with the medication to reduce
discomfort and pain.
✓ Explain importance of iron-rich foods to supplement iron.
✓ Explain methods of quantifying blood loss and reporting to
healthcare provider.
✓ Assist in and teach patient pain-relieving techniques to promote
self-sufficiency in managing pain.
✓ Assess meaning of dysfunction for patient to explore self-
concept issues.
✓ Encourage patient to express her feelings to increase
understanding of individual coping style.
