Today’s Topics Contraception Infertility Menstrual Disorders
Phases of the Menstrual Cycle • Proliferative Phase (Follicular) 6-14d • High Estrogen and FSHdevelop follicle • Ovulation • Secretory Phase (Luteal) 15-26d • High Progesterone, Decreasing Estrogen • Ischemic Phase 27-28d • Menstrual Phase 1-6d
The Menstrual Cycle Olds, S. London, M., Ladewig, P., Davidson, M. (2004). Maternal-newborn nursing & women’s health care.(7th ed.). Upper Saddle River, NJ.: Prentice Hall. (p. 211).
Contraception begins with Fertility Awareness • Ovulation • Ovum can be fertilized w/in 48 hrs • Sperm viable for 72 hrs • Problem pinpointing ovulation • Basal Body Temperature (BBT)[chart] • Progesterone increases = BBT increases • Take temp when awakened • Temp drops .2-.3 F; 24-36 before ovulation • Rises .7-.8 after ovulation--sample
Contraception begins with Fertility Awareness • Cervical Mucous (Spinbarkeit) • More abundant, thin clear, stretchy mucous at ovulation • Thickens and less amount until menses • Other Symptoms • Mittelschmertz • Increased libido • Bearing Down Pain
Physiological Methods • Calendar • Keep records for 6-8 months • 18 days from end of SHORTEST cycle • 11 days from end of LONGEST cycle • Abstain during “fertile” times • BBT—website with calendar • Billings Method
Barrier Methods • Male Condom • Hold onto ring when withdrawing • Female Condom • Diaphragm • Refit after each childbirth • Use with Contraceptive Jelly • Leave in for 6 hours AFTER intercourse • If repeat intercourse, use more spermicide • Cervical Cap • Leave in for 8-48 hours
Chemical Methods • IUD—Prevents fertilization • Mirena-5 years, SKYLA-3 yrs • Paragard -10 years • Risk of PID, Heavier periods (paragard), perforation, dysmenorrhea • Teach to string after each menses • Spermicides • May have to wait to dissolve • Reapply with repeat intercourse • Use with diaphragm/condom • Non-oxinol 9—Kills HIV and other STD’s
Chemical Methods—BCP’s • Types • Combination P & E • Progesterone ONLY “minipill” • Phasic • Side effects (table 4-2, pg 63; 10th ed) • Estrogen effects: N/V, weight gain, headaches, breast tenderness, etc. • Progesterone effects: acne, breast tenderness, ↓ libido, depression, fatigue, hirsuitism, weight gain, etc. • Contraindications • Thrombophlebitis, CHD, Breast CA, SMOKER • Some antibiotics DECREASE effectiveness
Long-Acting Chemical Methods • Implanon • Lasts up to 3 years • Flexible plastic rod the size of a matchstick that is put under skin in the upper arm • Chief side effect: irregular bleeding • Depo-Provera • Injection 4 x / yr • Prolonged amennorhea or uterine bleeding
Newer Chemical Methods • Contraceptive Patch • ORTHO EVRA • Contraceptive Ring • NuvaRing • A helpful website • http://www.ultimatebirthcontrol.com/
Emergency Contraception • Take 2 BCP’s at once and 2 more 12 hours later • Use within 72 hours after unprotected intercourse • Prevents implantation
Operative Sterilization • Male Vasectomy • Outpatient • 81-91% reversal • Ice for pain, swelling • NOT immediate sterility—up to 36 ejaculations to rid ducts of all sperm • Sperm count to verify • Female Tubal Ligation • Can be done with C/sec • General Anesthesia or epidural if done after vaginal delivery • 20 minutes • Less successful reversals
Outpatient Sterilization • Essure-small metallic implant that is placed into the fallopian tubes under hysteroscopic guidance • Induces scar tissue to form over the implant, blocking the fallopian tube and preventing fertilization of the egg by the sperm
99.8% effective • Oral contraceptives are often prescribed at least one month prior to insertion to induce endometrial atrophy and to prevent an undiagnosed pregnancy • Paracervical blocks are given to anesthetize the perineum • NSAIDs and Diazapam can be given during the procedure to minimize discomfort • Educate patients to use alternate contraceptive methods until a hysterosalpingogram is performed 3 months after placement to confirm complete blockage of fallopian tubes • 99.8% effective
Abortion • ElectivePerformed at woman’s request • Therapeutic performed for reasons of maternal or fetal health • 1st trimester • Roe v. Wade • 2nd trimester • States decide
RU-486 • Combination of 2 drugs • Mifepristone is an anti-Progesterone drug that stops the early pregnancy from growing. • Misoprostol is the second drug and causes the uterus to contract and an early pregnancy to be expelled.
Procedure • Confirm Pregnancy Blood test or U/S • Take Mefipristone (1 pill) • 2-4 days later, Take Misoprostol • Come back to office in 2 weeks—U/S to confirm NO pregnancy
Side Effects • Abdominal cramping pain, bleeding, nausea, vomiting, and diarrhea, which may be extreme in some cases. • Dilatation and Curettage (D&C) may be needed in rare cases.
Plan B Levonorgestrel • Emergency contraception-not effective if already pregnant • Reduces risk of pregnancy when take after unprotected sex • With in 72 hours after intercourse • No prescription required for 17 years and older, prescription needed 16 yrs and younger
Plan B • Levonorgestrel works by stopping ovulation, fertilization, or implantation, depending on where a woman is in her cycle. • Side effects • Nausea, abdominal pain, fatigue, headache and changes in menstural cycle
Assess patient’s knowledge, lifestyle, preferences, any cultural taboos or implications • Take a thorough patient history to identify any factors that put a patient at high risk for complications and rule out certain contraceptives. Nurse’s Role in Birth Control Counseling • Provide handouts, demonstration, discuss advantages and disadvantages of each method, • Allow time for questions and feedback
