Study Notes
Sedative Drugs in Labor
- Commonly used sedatives include barbiturates and hypnotics: secobarbital sodium (Seconal) and pentobarbital sodium (Nembutal).
- Phenothiazine derivatives and hydroxyzine may be administered alone or with narcotics during early and active labor.
Anesthesia in Childbirth
- Anesthesia involves loss of pain sensation, potentially with loss of consciousness, during labor and delivery.
- Two pain types during childbirth:
- Visceral pain from cervix and uterus: transmitted via sympathetic fibers entering spinal levels T10, T11, T12, and L1.
- Somatic pain from pressure and stretching of the vagina and perineum: transmitted to sacral regions S2, S3, and S4 by the pudendal nerve.
Regional Anesthesia
- Provides pain relief during labor without loss of consciousness by blocking conduction of pain signals.
- Allows patients to experience labor while alleviating discomfort in targeted areas.
Drugs Enhancing Uterine Muscle Contractility
- Uterotropic drugs like oxytocin, ergot alkaloids, and certain prostaglandins stimulate uterine smooth muscle.
Oxytocin
- Administered intravenously, oxytocin assists with labor induction and augmentation in patients experiencing inadequate contractions.
- Lower starting doses may be more effective for patients with uterine inertia.
Ergot Alkaloids
- Cause direct stimulation of smooth muscle receptors: not recommended during labor due to risk of sustained, harmful contractions.
- After delivery, effective in managing postpartum hemorrhage and promoting uterine involution, with methylergonovine maleate (Methergine) being the most utilized derivative.
Combined Oral Contraceptives
- High effectiveness (92% to 99.3%) for contraception, but potential side effects include skin reactions, menstrual cramps, and vision changes.
- Variants are available:
- Monophasic pills provide constant estrogen-progestin ratio.
- Biphasic or phasic pills vary in hormone levels.
Spermicides
- Chemical agents like nonoxynol-9 that inactivate sperm before they ascend through the cervix.
NuvaRing
- A flexible ring inserted vaginally, releasing daily doses of estrogen and progestin similar to lower-dose combined oral contraceptives.
Progestin-Only Contraceptives
- Options include various formulations aimed at preventing pregnancy but less effective for women over a specific weight.
Alternative Therapies
- Black cohosh may alleviate menopausal symptoms like hot flashes.
- Mifepristone (RU486): anti-progestin; causes breakdown of uterine lining, ending support for the embryo.
- Misoprostol induces uterine contractions to expel pregnancy products.
Menopause Stages
- Perimenopause: transitional phase with irregular cycles, heavy/light bleeding, and common symptoms like hot flashes.
- Menopause: permanent cessation of menstruation after one year without periods.
Hormone Therapy (HT)
- Intended to relieve menopausal symptoms: hot flashes, vaginal dryness, and mood changes.
- Types include estrogen-progestin therapy (EPT) for women with intact uterus and estrogen therapy (ET) for those post-hysterectomy.
- Available as oral, transdermal, and vaginal preparations, particularly effective for vaginal dryness.
