These typically resolve within 40 hours if due to pe but persist longer after acute mi. •• electrocardiogram may show nonspecific st-segment and t-wave changes and tachycardia. Diagnostic imaging tests •• a computed tomography (ct) scan is the most commonly used test to diagnose pe, but some institutions still use a ventilation/perfusion (v/q) scan. Spiral ct scans can detect emboli in the pulmonary arteries. A v/q scan measures the distribution of blood and air flow in the lungs. When there is a large mismatch between blood and air flow in one area of the lung, there is a high probability the patient has a pe. •• pulmonary angiography is the gold standard for diagnosis of pe. However, it is an invasive test that involves injection of radiopaque contrast dye into the pulmonary artery. The test is expensive and associated with significant risk of mortality. Improve venous blood flow by mechanical means.

Certain agents such as male condoms require the male partner to play an active role in contraception. Cost may also be an issue for patients. Insurance may not cover all forms of contraception, and patients may have to bear the entire cost for certain options.

Therefore, it is difficult to determine the true efficacy of contraceptives in preventing unwanted pregnancy. Table 48–1 shows the percentage of women who experience unintended pregnancy within 1 year of contraceptive use with ongoing sexual activity. 3 oral contraceptives (combination) cocs contain a synthetic estrogen and one of several steroids with progestational activity. Most oral contraceptives contain one of three types of estrogen. Ethinyl estradiol (ee), which is pharmacologically active. Mestranol, which is converted by the liver to ee. Or estradiol valerate, which is metabolized to estradiol and valeric acid. Many different progestins are found in the various oral contraceptives. These include norethindrone, norethindrone acetate, ethynodiol diacetate, norgestrel, levonorgestrel, desogestrel, norgestimate, drospirenone, and dienogest. The primary mechanism by which cocs prevent pregnancy is through inhibition of ovulation. Fsh and lh regulate the production of estrogen and progesterone by the ovaries. Secretion of estrogen and progesterone by the ovaries occurs in a cyclic manner, which determines the regular hormonal changes that occur in the uterus, vagina, and cervix associated with the menstrual cycle. Cyclic changes in the levels of estrogen and progesterone in the blood, together with fsh and lh, modulate the development of ova and the occurrence of ovulation. The estrogen component of cocs is most active in inhibiting fsh release. 3 however, at sufficiently high doses, estrogens also may cause inhibition of lh release. In low-dose cocs, the progestin component causes suppression of lh. 3 ovulation is prevented by this suppression of the midcycle surge of both fsh and lh3 and mimics the physiologic changes that occur during pregnancy.
