Randomized Controlled Trial Comparative Study Clinical TrialDoes magnesium sulfate affect the length of labor induction in women with pregnancy-associated hypertension?
Our purpose was to determine whether seizure prophylaxis with magnesium sulfate prolongs induction of labor in women with pregnancy-associated hypertension. ⋯ Compared with phenytoin, magnesium sulfate seizure prophylaxis in women with pregnancy-associated hypertension does not prolong the induction of labor nor does it result in an increase in cesarean deliveries.

Histologic evidence of old intrauterine bleeding is more frequent in prematurity.
Our purpose was to study the incidence and location of histologic evidence of intrauterine bleeding in preterm and term placentas. ⋯ Decidual bleeding is common in all clinical types of preterm birth and is most common in preterm preeclampsia and nonhypertensive abruption placentae. A clinical history of bleeding is not correlated with the presence of decidual hemosiderin. Bleeding in the basal plate is related to histologic evidence of chronic uteroplacental vascular pathologic processes, which in cases of spontaneous prematurity (premature rupture of membranes, preterm labor, nonhypertensive abruptio placentae) may be associated with decidual bleeding which occasionally may be clinically manifested as gestational bleeding.

Clinical TrialFavorable hemodynamic effects of magnesium sulfate in preeclampsia.
Our purpose was to evaluate the hemodynamic effects of magnesium sulfate in preeclamptic and preterm labor patients. ⋯ Magnesium sulfate infusion appears to have a prolonged hemodynamic effect in the preeclamptic patient. Sustained reduction in systemic vascular resistance and an increase in cardiac index is found in patients with preeclampsia but not in preterm labor.

Randomized Controlled Trial Clinical TrialPyridoxine for nausea and vomiting of pregnancy: a randomized, double-blind, placebo-controlled trial.
Our purpose was to determine the effectiveness of pyridoxine for nausea and vomiting of pregnancy. ⋯ Pyridoxine is effective in relieving the severity of nausea in early pregnancy.

Randomized Controlled Trial Clinical TrialThe effect of topical 20% benzocaine on pain during loop electrosurgical excision of the cervix.
Our purpose was to evaluate the effect of cervical application of 20% benzocaine on the pain associated with subsequent cervical injection of local anesthetic and tissue excision during the loop electrosurgical excision procedure of the cervix. ⋯ Preoperative cervical application of 20% benzocaine does not appear to reduce the pain associated with either subsequent local anesthetic injection or tissue excision during the loop electrosurgical excision procedure of the cervix.
