Effect of amoxicillin sulbactam in threatened preterm labour with intact membranes: a randomised controlled trial.

Objective: To determine whether treatment with amoxicillin-sulbactam in women with threatened idiopathic preterm labour will prolong the gestation and reduce preterm birth rates in a Latin-American population.

Methods: A double-blind, placebo-controlled, randomized trial was conducted in 96 women who were hospitalized for preterm labour between 24 and 34 weeks of gestation at the Pereira Rossell Hospital, in Montevideo, Uruguay. The primary outcome measure was prematurity.

Meperidine for dystocia during the first stage of labor: A randomized controlled trial.

Objective: This study was undertaken to evaluate whether the administration of meperidine decreases the length of labor in patients with a diagnosis of dystocia during the first stage of labor.

Study Design: Women with term singleton pregnancies who received a diagnosis of dystocia and required an active management of labor were randomly assigned to receive either 100 mg of meperidine or placebo. The primary outcome measure was length of labor.
