Gynecology

Menstrual Patterns

  • Normal Menstrual Cycle:

    • Interval: Typically ranges from 21 to 35 days, with the ideal being 28-29 days.

    • Duration: Lasts from 1 to 8 days of bleeding.

    • Amount: Normal blood flow equates to less than one pad or tampon every 3 hours. The total amount of menstrual blood loss ranges from 25 to 60 ml, with an average of about 35 ml.

  • Factors Impacting Menstrual Cycle:Emotional, physical, and environmental factors greatly influence menstrual cycles. Stress, lifestyle changes, and medical conditions can alter the regularity and symptoms of menstruation.

Severe Acute Bleeding:

  • This is defined as bleeding that requires more than one pad or tampon per hour.

    • Double Protection: Use of 2 pads/tampons or 1 of each.

    • Triple Protection: Use of 3 pads/tampons or 1 pad and 2 tampons, indicating a need for immediate medical evaluation.

Ovarian Cycle

  • Phases:

    • Follicular Phase (Days 1-14): Follicle matures under the influence of Follicle-Stimulating Hormone (FSH) and Luteinizing Hormone (LH) until ovulation occurs.

    • Luteal Phase (Days 15-28): The ovum leaves the follicle, and the corpus luteum develops under the influence of LH, releasing hormones to prepare the uterus for potential implantation.

Uterine Cycle

  • Phases:

    • Menstrual Phase (Days 1-6): Characterized by low estrogen levels, leading to the shedding of the endometrium.

    • Proliferative Phase (Days 7-14): Estrogen levels peak, the endometrial and myometrial thickness increase, and cervical mucus becomes favorable for sperm passage.

    • Secretory Phase (Days 15-26): Dominated by progesterone, preparing the endometrium for possible implantation of a fertilized egg.

    • Ischemic Phase (Days 27-28): Hormone levels drop, leading to the endometrial shedding and the start of menstruation.

Hormonal Function

  • Estrogen:

    • Essential for the development of female secondary sexual characteristics, the proliferation of endometrial mucosa, and the overall regulation of the menstrual cycle.

  • Progesterone:

    • Decreases uterine contractility and plays a critical role in preparing the body for pregnancy by initiating secretory changes in the endometrium.

  • FSH and LH:

    • FSH: Facilitates the maturation of ovarian follicles.

    • LH: Triggers the final maturation of the follicle and stimulates hormone production in the corpus luteum.

Dysfunctional Uterine Bleeding:

  • Common issues arise at the beginning of menstrual cycles (often due to anovulation) and during perimenopause as hormonal levels fluctuate.

  • Up to 50% of women may experience menstrual irregularities due to various causes, necessitating further medical evaluation.

Menstrual Conditions

  • Abnormal Uterine Bleeding (AUB):Any deviation from normal menstruation or a cycle pattern can signify underlying issues needing assessment.

  • Heavy Menstrual Bleeding (HMB):Excessive bleeding that significantly interferes with daily activities and quality of life.

  • Intermenstrual Bleeding (IMB):Light bleeding that occurs between menstrual periods, often requiring evaluation.

  • Postmenopausal Bleeding (PMB):Bleeding occurring more than a year after the last menstrual period, often requiring diagnostic procedures.

Menstrual Irregularities

  • Causes can include:

    • Pregnancy

    • Hormonal imbalances (e.g., anovulation)

    • Polycystic Ovary Syndrome (PCOS)

    • Uterine fibroid tumors

    • Infections

    • Endometrial polyps or cancers

Primary Amenorrhea

  • Definition: The absence of menstruation by age 14 in the absence of secondary sexual characteristics or by age 15 regardless of development status.

  • Causes:

    • Congenital obstructions

    • Chromosomal disorders (e.g., Turner syndrome)

    • Hormonal imbalances (e.g., hypothalamic amenorrhea)

Secondary Amenorrhea

  • Definition: The absence of menses for 3-6 months in women who have previously menstruated.

  • Common Causes:

    • Pregnancy

    • Lactation

    • Hormonal imbalances

    • Stress-related factors

    • Use of oral contraceptives

Primary Dysmenorrhea

  • Definition: Menstrual cramps without any identifiable underlying disease.

  • Pathophysiology: Caused by release of prostaglandins that lead to increased uterine activity, causing pain and discomfort.

  • Management: Non-steroidal anti-inflammatory drugs (NSAIDs) should be taken before the onset of menses for alleviation.

Self-Care for Dysmenorrhea

  • Recommended are regular exercise, application of heat to the lower abdomen, and maintaining a healthy diet.

  • It’s advised to avoid high salt intake, and vitamins B6 and E may help in symptom alleviation.

Secondary Dysmenorrhea

  • Associated with reproductive tract pathologies, including conditions like endometriosis, fibroids, and ovarian cysts.

Leiomyoma/Fibroids

  • Description: Benign tumors originating from smooth muscle cells, affecting about 20-25% of reproductive-age women, with a higher incidence in African-American women.

  • Symptomatic Fibroids: May necessitate surgical intervention, including hysterectomy, depending on severity.

Treatment for Fibroids

  • Pharmacologic Options: GnRH therapy serves as a temporary solution, while hormonal treatments are indicated for small, asymptomatic fibroids.

  • Surgical Options: Reserved for larger or symptomatic fibroids.

Endometriosis

  • Definition: The presence of endometrial tissue outside the uterine cavity, which can lead to inflammation and pain.

  • Symptoms: Varying symptoms including infertility, dysmenorrhea, pain during intercourse, heavy or prolonged menses, and chronic fatigue.

  • Diagnosis: Primarily through patient history and laparoscopy for visualization and potential biopsy.

  • Treatment: Available options include both medical management (such as hormonal therapies) and surgical interventions.

Nursing Management for Endometriosis

  • Focused on effective pain relief and preservation of reproductive capacity, including support and education on available treatment options.

Polycystic Ovarian Syndrome (PCOS)

  • Definition: An endocrine disorder characterized by elevated estrogen and testosterone levels, as well as decreased progesterone.

  • Diagnosis: Based on the presence of ovulation dysfunction, clinical signs of hyperandrogenism, and ultrasound finding of polycystic ovaries.

  • Symptoms: Amenorrhea, hirsutism, obesity, signs of insulin resistance, and issues with infertility.

  • Nursing Management: Emphasizes emotional and educational support, lifestyle changes (diet and exercise), hormonal treatments to regulate cycles, and medications to improve insulin sensitivity.

Pap Smear & Pelvic Exams

  • Pap Smear: A cervical cytology test used to screen for abnormalities that may indicate cancer or precancerous changes; enhanced by liquid-based cytology for improved accuracy.

Pap Screening Guidelines**:

  • Under 21: No screening necessary

  • Ages 21-29: Cytology alone every 3 years

  • Ages 30-65: Either cytology every 3 years or HPV testing every 5 years.

Abnormal Pap Results

  • May necessitate follow-up tests or procedures such as colposcopy or biopsy to evaluate detected abnormalities further.

Vaginal Infections

  • Symptoms: Common symptoms include discharge, irritation, itching, and dyspareunia (pain during intercourse).

  • Common Types:

    • Bacterial Vaginosis: Characterized by a fishy odor.

    • Candidiasis: Usually presents with a white, curd-like discharge.

Pelvic Inflammatory Disease (PID)

  • Definition: An infectious condition that affects pelvic reproductive organs; it’s important to note that many sexually transmitted infections (STIs) can be asymptomatic in women, making awareness and screening critical.

STIs and Treatment:

  • Trichomoniasis: Treated with Metronidazole; it is a common and curable STD.

  • Chlamydia: Treated with Azithromycin; poses the risk of infecting newborns during delivery.

  • Gonorrhea: Managed with Ceftriaxone; often asymptomatic in females.

  • Herpes: Treatable with Acyclovir for symptom management, no cure available.

  • Syphilis: Managed with Penicillin G; may have serious long-term systemic effects if untreated.

  • Condylomata (Genital Warts): Caused by HPV; various treatment options exist, including preventive vaccines.
