The characteristics and treatment of preeclampsia and eclampsia are reviewed. Risk factors for preeclampsia include (1) nulliparity, (2) a mother or sister(s) with a history of the disorder, (3) essential hypertension or renal disease, or (4) a twin or molar pregnancy. Preeclampsia is diagnosed when the systolic blood pressure (BP) increases by 30 mm Hg or the diastolic BP increases by 15 mm Hg after the 20th week of gestation and the BP rise is accompanied by edema, proteinuria, or both. ⋯ Among antihypertensive agents, i.v. hydralazine is preferred in this country to control blood pressure in the severely preeclamptic or eclamptic patient. Several studies provide promising evidence that low-dose aspirin (60-150 mg daily beginning at 28-30 weeks of gestation) prevents preeclampsia in women who are at risk for its development. Until additional comparative studies are completed, magnesium sulfate and hydralazine will remain the standard of care for the treatment of preeclampsia in the United States.

The physicochemical properties, pharmacology, pharmacokinetics, serum concentrations and clinical effects, adverse effects and contraindications, and dosage of transdermally administered fentanyl are described, and clinical studies evaluating the use of a transdermal fentanyl system in the treatment of postoperative pain and chronic cancer-associated pain are reviewed. After application of a transdermal system, fentanyl is absorbed into the skin beneath the patch, where a depot forms in the upper skin layers. Plasma fentanyl concentrations are barely detectable for about two hours after patch placement. ⋯ The 25-micrograms/hr patch should be used for initial treatment in patients not previously treated with narcotics. The dosage may be gradually increased until effective analgesia is obtained. Although experience with the product is limited, transdermally administered fentanyl appears to be effective for the long-term management of cancer-related pain.
