Preterm labor and delivery remain a significant problem in contemporary obstetric practice. Although the exact cause remains unclear, it is most likely to be multifactorial in nature. No satisfactory screening tool or marker currently exists to firmly establish the diagnosis of impending labor. However, epidemiologic and historical variables associated with preterm delivery show some promise in this regard and are currently being evaluated in preterm prevention programs. Appropriate management of preterm labor mandates early recognition of subtle signs and symptoms; successful therapy is dependent on this issue. The approach to the clinical management of the patient in preterm labor used at our institution is described. Therapy with beta-adrenergic receptor agonists is currently the recommended pharmacologic treatment of this disorder. A review of other tocolytic agents and their usefulness in the management of preterm labor are presented.
