Randomized Controlled Trial Multicenter Study Clinical Trial
Effect of early amniotomy on the risk of dystocia in nulliparous women. The Canadian Early Amniotomy Study Group.
Early amniotomy has been advocated as a means of preventing dystocia, but its efficacy has not been studied prospectively. The purpose of this multicenter study was to determine whether routine early amniotomy reduces the risk of dystocia for nulliparous women in spontaneous labor. ⋯ Early amniotomy is an effective method of shortening the duration of labor and reducing the frequency of dystocia among nulliparous women in labor, but it does not lower the rate of cesarean section.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Ondansetron compared with dexamethasone and metoclopramide as antiemetics in the chemotherapy of breast cancer with cyclophosphamide, methotrexate, and fluorouracil.
Although ondansetron was found to be effective as an antiemetic in numerous clinical trials of highly emetogenic combination-chemotherapy regimens that included cisplatin, its role in milder emetogenic regimens has not been fully defined. To address its use with a widely used but less emetogenic regimen, we performed a double-blind, randomized clinical trial comparing ondansetron with dexamethasone and metoclopramide in patients with breast cancer receiving chemotherapy with cyclophosphamide, methotrexate, and fluorouracil. ⋯ For women with breast cancer who are being treated with cyclophosphamide, methotrexate, and fluorouracil, the efficacy of dexamethasone and metoclopramide in controlling nausea and vomiting equaled or exceeded that of ondansetron.
